Lessons in Invention Development - Part 2

!±8± Lessons in Invention Development - Part 2

The thought entered my mind that perhaps price, place, and promotion weren't the only lessons to master. But I did redesign the product, too, in search of the right equation. Still, all of my attempts had failed. I had been blinded by my own dogged perseverance, causing me to fail the most crucial lesson of all. But what could that lesson be? I strained to find the answer, but it seemed time had run out. Then it was confirmed: offers for additional financial backing from my investor, representation, and free trade shows ceased, and with them my excitement and enthusiasm. I'd all but given up and others already had. What consumed me these days was how to explain to my friends, family and readers of my resume that I had lost six figures developing "pie-in-the-sky" inventions. I became seriously discouraged and as stressed as I'd ever been. I got in the habit of bringing a bath towel to bed with me so when I awoke during most nights, drenched in a cold sweat, I would have something to dry off with. Those around me sensed disaster and distanced themselves from me. Early into the invention project I ended a long-term relationship with my girlfriend who cringed at the amount of money I was spending and constantly reminded me of it. I couldn't tolerate her incessantly nagging me. She really thought I wasn't in my right mind. Even my friends lost patience with the never-ending saga. This inventing business was exacting a heavy toll, and I couldn't decide which was worse, flange installing or my invention project-"the disease or the cure."

Haunted by the memory of all the rejections during the last year and a half, I strained to find meaning at the last tradeshow as I demonstrated the last flange tool design. I was asked the same question for the nth timeby the nth tradesman-"why do they make the flanges like that?" We agreed that the flange design was questionable, but I sensed that he didn't think my tool concepts were the solution to the problem. Then I had a flash of insight, more importantly, a renewed perspective. My attention centered on the initial design options David and I had discussed at our first meeting. One design was of a flange with a hexagonal-shaped tightening surface. This was the turning point where I realized that I had veered down the wrong path by developing the flange tool of the same shape. A new flange design would offer the Reps and wholesalers a new utility that I was sure they could sell, as it would solve the installation problem for the tradesmen, and allow them to pass on the cost to their customer. My hope was rejuvenated.

I envisioned becoming successful with the first new circulator flange in as many as fifty years. Only now a shadow loomed over it, threatening it in its infancy. My investor surprised me by saying "No more, John!" She had often exclaimed, "Your inventions are all tinker toys!" To her I had also become the boy who cried wolf. I felt this time was different, just as in the tale of the boy and the wolf. Truthfully, I think she knew it, too. She was just being firm in her opposition to spend more money, merely out of principle.

Mary had considered using her 100-acre farm as collateral against a loan to my business early on. She had been ready to bet the farm-literally-but now was far from that liberal way of thinking. I felt hopeless, knowing she had already spent the money from the sale of her house where I had made the original service call roughly a year earlier. She had stayed with me for a year and 30 failed designs, I couldn't expect anything more. I could have begged her, but I had never asked her for money - she had just always known when to contribute in this way. And what if this idea failed too? Mary was 78 then, and her best friend since college had nicknamed her "CW", short for Crazy Woman, many years earlier. Exactly why I'm not certain, but it seems she took a risk in the past, and lost, with some sort of refrigeration business, and I didn't want to give her friend more fodder. Nevertheless, I persisted in explaining the significance of this latest discovery to her from as many angles as seemed relevant. I realized the simplest solutions often are the best ones. And I had to convince her that this flange was my best one. Thankfully, I found several people in the industry to corroborate my belief that I really had invented a "winner" this time around. It was then that I knew I was right. Finally, she believed the flange was a good idea and invested even more money.

I met with David once again and revisited the sketch of the tool/flange that we had made years earlier. We modified the design to include an octagon shaped nut that could be easily gripped by an ordinary wrench. The only significant difference between the flange tool and the new flange was that the tool had a hexagonal nut. It was so simple, like a Post It NoteÒ. The prior art suggested that nobody had done this with a circulator flange before, so I applied for as many design and utility patents as my lawyer and I could think of. At that time I conjured up nearly 70 ideas for a range of flange designs.

I completed development on four of the designs in a month. It took just a few phone calls, and in an instant I was back on track. Once again the president of the local supply house offered his advice: 'Call the executive vice president of marketing at a Rep firm, Emerson-Swan, Inc., in Massachusetts and ask him what he thinks about the flange.' This firm represented a Rhode Island company, Taco, Inc., a manufacturer of "hydronic" components including circulators and flanges. Taco was the market leader in the region and their products enjoyed high brand loyalty. What I soon learned would delight and amaze me.

I called the VP, and we met two days later in the waiting room of a Mercedes dealership while his car was being serviced. He seemed very impressed with the flanges I showed him, though I had the feeling there was something he wasn't telling me-he seemed too interested. These were such simple low-tech sand castings. I sort of accepted his energy, rationalizing that it was typical to see a person's enthusiasm when they saw my inventions for the first time. But I decided to do a little digging and I am glad I did. I learned that Taco was losing money on their flanges, and were factoring that loss into the sell-price of their circulators. The negative contribution to profit stemmed from increased competition, resulting in the loss of 30% of their market share for flanges. This explained the VP's immediate enthusiasm for a new flange design.

A week had passed, and he stayed true to his word that he would arrange a meeting with Taco. I met with Taco's VP of marketing and a handful of managers at their plant. As expected, their interest level was high, and negotiations began. I was now in for an education in the art of negotiating. The pursuit of success had created immense strife in my personal life, but the pursuit of "a deal" dwarfed my earlier trials.

Negotiations weren't going the way I had naively hoped, so I decided to shop the flange around, realizing that if Taco was interested in the flanges then their competitors might be, too. They were. I discovered that they all had problems with their flanges. This seemed incredulous. It wasn't long before I was on a plane to California to meet with executives from the largest pump manufacturer in the world, Grundfos-all expenses paid. But Taco sold the greatest number of this style of threaded circulator flange in the world, over a million a year. Knowing this helped me determine the total market size, and I seriously considered supplying the market with flanges myself. I made contacts with an array of other manufacturers, Reps and potential investors. I lined up production agreements in case negotiations with the two primary companies fell through. Nonetheless, I pursued them vigorously.

The last thing Taco needed was yet another company competing against them. Therefore, they had the most to lose without my design, and the most to gain with it. They were aware that if they could regain their lost market share with a patent pending flange, a "better mousetrap", then a deal with me made a lot of sense. The fact that they produced so many flanges ensured the possibility of significant royalties for my investor and me, and I was determined to pay her back. So six months later I signed a license agreement with Taco on two flange designs, but not before asking for help one last time from the supply house president, this time with negotiations; I needed a mediator. Taco and I had reached an impasse in negotiations, but once the president agreed to mediate it took just 3 weeks to settle the deal, and the first check, ,000, was signed to my company.

Since closing the deal, Taco has replaced their old standard with my designs. The "freedom Flanges," as they've named them, are on the market, and the positive response has been nothing short of a consensus. It appears that a new standard has been created. The most often asked question is "Why didn't they do this years ago?" I wish I could collect royalties on my answer to that question. Whenever I hear that question I am reminded of an inspirational statement on a poster in my insurance agent's office: "What we can easily see is only a small percentage of what is possible. Imagination is having the vision to see what is just below the surface; to picture that which is essential, but invisible to the eye." This flange solution was a glaring example of a concept so simple that no one before me considered looking for it. The torturous route that I had taken may have been less grueling and more direct if I had given equal attention to the flange option right from the beginning. Hindsight is so clear. Is it not?

Eight months following completion of the first deal, Taco and I signed a second agreement on three valve inventions. Recently we began discussions on my latest invention ideas.

Seeking to create tools based on a flange design reminds me of the 3M Company's search for a new adhesive. When their engineer pasted a sticky substance on squares of paper, to keep his place in his church hymnal, he had created what would become the Post-It NoteÒ; as simple an idea as my flange. Another notable inventor, Norm Larson, created 39 chemical formulas to inhibit rust before his 40th proved successful: "Water displacement, 40th attempt" in other words, WD-40®. I became successful with my 30th attempt, though no comparison can be made to the 100 million dollar a year success that WD-40® has become. It seems solutions to certain problems are often discovered before they are recognized as solutions, and it can require carrying an idea through a process of elimination before the successful discovery is made. My plan wasn't to start a one-product company-one-product companies are rarely successful. Although, failing with the tools and succeeding with the flange made it apparent that the simplest designs can often be the most successful. Moreover, I knew little about the market for flanges in the beginning of my journey and didn't think I could compete with Taco's established North American distribution, even with a new flange design. Thankfully, I had come full circle with my journey and was a lot wiser for having taken the trip. With attainment of inventing wisdom my hair has begun to gray, but I no longer need that bath towel.

The invention development process doesn't have to be as difficult as it was for me. I should have done a lot more market research before spending so much money on patent applications, costly patterns and prototypes, production runs, and, generally, spinning my wheels on whimsical ideas. In a perfect world a ,000 market analysis in the beginning may have helped me choose the path of profit much sooner. I would have discovered there was far greater market potential for flanges than for flange tools. I estimate I might have saved 5,000 if I had bypassed the tool approach and gone directly with the flanges and valves, my last five inventions.

Looking back at my experiences from my present perspective as president emeritus (2000) of New Hampshire Inventors Association, I've concluded that many other inventors are going through the same kind of educational process; I see mostly failure and small successes, as most inventors will have to learn by doing and aren't prepared for what it takes to succeed. Inventors need to have an awareness of the invention development process and its pitfalls. Also, they will need to possess passion and determination and, more importantly, a marketable idea. Moreover, I know the following declaration by Thomas Edison echoes in the minds of other inventors, as it has in mine: "Had I known in advance what I was in for I would not have started!" But I did start, and I finished successfully. I pushed forth with drive and creativity I didn't know I was capable of and beat the odds. 98% of inventors fail, many of them making the same predictable mistakes that I made.

It should be noted that my invention "boot camp," and my ultimate success, would not have been possible without the ongoing faith of my investor. In exchange for her risk-taking Mary will receive a ten percent return on her total investment, plus 40% of royalties from the second license agreement. Most inventors run out of money before they succeed; I would have too if not for Mary. She was not only my Angel, but my savior during my darkest hours of seemingly imminent failure. I'm very thankful that she will be repaid.

An intangible benefit to me is that I've learned more about my capabilities and limitations through this process than through any other personal challenge. In overcoming this challenge I have found the new career path I hoped to discover. I am presently in school completing a degree in business that I started in the 80s and will continue on in engineering-I'm reinvesting my royalties. Ironically, and with any luck, I've invented products for the trade that I may never need to return to and use.

Slow Hot Water - Why Your Hot Water is Slow and a Simple Fix!

!±8± Slow Hot Water - Why Your Hot Water is Slow and a Simple Fix!

Many people find it annoying that they have to wait for their hot water to reach the fixture. If you water heater is a substantial distance from your fixture, you could have a very long wait.

There are a number of factors involved with how long it will take for the hot water to reach your sink, but there are really four main variables. The first is how long the pipe is between the heater and the fixture, the second is the diameter of the pipe, and the third is the flow rate of the fixture itself. The last variable is how much heat the cold pipes pull out of the water on the way to your fixture.

Let's begin with the piping layout. When a home is built there are no plumbing blue prints to follow, so the plumbers just connect up the piping however the individual doing the job feels like it. Whatever is easiest often is the only criteria. I've encountered tract homes that have identical floor plans yet the plumbing is connected up substantially different.

If your heater is 30 feet from the fixture as the crow flies you probably have at least 40 feet of pipe. The simplest plumbing layout would have a pipe connecting from your water heater outlet, running either down to the crawl space or up to the attic, or even under the slab if you have slab floors.

Now add the 30 feet of pipe to the fixture, and the pipe running either up to the fixture or down to the fixture. So you now have at least 40 feet of pipe. However, seldom is the pipe run diagonally, usually following along beams or through walls etc, making right angle turns here and there. The pipe could be 50 feet or longer by the time it reaches your fixture.

The amount of water flowing through the pipe and the pipe diameter determine the speed at which the water flows. The flow rate of the water is most likely determined by the flow rate of the faucet or fixture.

At only 40 psi a ½" diameter copper pipe 100 feet long would have a flow rate of over 6 gallons per minute with a velocity through the pipe of over 10 feet per second. At that rate your hot water would arrive at your sink in about 5 seconds! Large diameter pipes would have even higher flow rates.

The Federal Energy Policy Act of 1992 required all faucet and shower fixtures made the USA to have a flow rate of no more than 2.2 GPM at 60 PSI. Since the pipe itself will allow a much greater flow rate, your water velocity in the pipe will be limited by the flow rate of the fixture. The larger the pipe is, the lower the velocity will be with a fixed flow.

At 2.2 gallons per minute, the velocity of the water in ½" diameter copper pipe is about 3 feet per second. If you are at a kitchen sink it will take about 16 seconds to get the hot water, assuming the flow rate of your fixture is 2.2 gallons per minute, if the cold pipe wasn't sucking any heat out of the water.

Normally bathroom sink fixtures are restricted to 1 gallon per minute or less, and many shower heads are 1 gallon per minute. At one gallon per minute the time to travel 50 feet would be 32 seconds.

Now we come to the part where the cold pipes are pulling the heat out of the water. There are some variables involved here, with the important ones being the ambient temperature of the piping material, what the pipe is made out of, and once again, the flow rate of the water.

Colder pipes absorb more heat, heavier pipe material hold more heat and so pulls more heat from the water, and the slower the water travels, the more heat gets removed. Insulating the hot water piping helps in that it keeps the pipes from getting as cold and reduces the ongoing heat loss from the pipes to the air, resulting in a higher temperature during usage.

The time it takes to get hot water at the fixture can easily double when the heat loss to the pipes is taken into account.

If you have a tankless water heater, then you are even worse off, since the whole water heater is like a long cold pipe. In order to get full temperature hot water out of the outlet it has to pass all the way through the heater from the inlet to the outlet. Instead of starting with hot water your starting with cold water and a cold heater, which takes time to heat. The owners of tankless water heaters need to add 10 or 15 seconds to the wait.

The fastest hot water delivery would be provided by using small diameter pipe, insulating the pipe, using plastic pipe instead of metal, and keeping the length of the pipe to a minimum.

The good news is that there are several products available that help you get your hot water faster without changing your plumbing system. Not only do you get your hot water faster, you don't run any water down the drain while you wait.

There are basically two approaches to the problem. One approach is to circulate warm water through the piping so that the pipe doesn't suck heat out of the water while it's on its way. This provides a substantial improvement in delivery time. These products consist of a small pump that mounts under the sink furthest from the water heater, which is temperature controlled, turning off and on as needed to keep the water in the piping system at between 85 and 95 degrees F.

The water is circulated from the water heater through the hot water pipes to the pump, and then on into the cold water line and back to the water heater inlet.

The down side is that the cold water pipes no longer have cold water...it's more like luke-warm, which some people don't mind, and some don't care for it. Another problem is that it uses a lot more energy since the water heater has to work harder to keep the water in the pipes at above ambient temperature.

The warm-water systems will not work with tankless water heaters.

The second approach is to again mount a small pump at the sink furthest from the water heater, but instead of keeping the pipes full of warm water the pump is only activated when hot water is wanted. When activated these pumps pump the water rapidly to the fixture at higher flow rates than the fixtures could provide. When the hot water reaches the pump, it shuts off.

Since the water is flowing at a higher than normal flow rate it arrives more quickly, and since it is traveling at a higher velocity, the pipe absorbs less heat from the water. Again, no water gets run down the drain. These systems are called "demand hot water systems" since they only operate on demand, i.e. when the user pushes a button that starts the pump.

Demand type hot water systems will work with tankless water heaters as long as they produce enough flow. Some pumps do and others don't, so check with the manufacturer of the demand system to make sure it will work with your model of tankless heater.

The warm-water pumping systems are manufactured by Laing, Grundfos, RedyTemp, and others. The demand type systems are manufactured by Chilipepper Sales, Metlund, Taco, and others. Suggested retail prices range from about 0 to about 0.

Installing one of these systems not only provides the convenience of fast hot water, but can also save thousands of gallons of water per year. A typical family of four can save over 12,000 gallons of water a year.

Along with the water savings comes a reduction in green house gas emissions since energy is used to pump and treat the water in most residential water systems. And don't forget about the reduction in sewage, the same energy reduction applies to it.
