In the future, I may consider such a line of work. Several times, I have thought about how nice it would be to take a more active role in the design of adult diapers. The engineering aspects could be fun. Product design and testing would also be pleasant. Often times, I have wondered how many people involved in the design of adult diapers actually wear them. My dream job would be the owner of a small diaper factory. Too bad the cost quickly enters the millions.
The best person to involve in the design of a product is actual users. A baby diaper design would be best handled by a mother. A youth/teen diaper should have good emphasis on bed wetters, but should not be limited to such constraints. Adult diapers should cover the widest group possible. Abena and Tena have the best product ranges, but have room for improvement. While an incontinent person may have more experience with diapers, a DL should not be excluded. Anyone who wears a diaper for an extended time will be able to provide good suggestions for the fit, tapes, and other such items. A diaper that does not stay in place on me while I sleep will likely not work well for others. The absorbency, discreteness, and look will vary from person to person without regards to reason for use. If you are wearing it in public, you will want a thinner, more discrete design. If it is for overnight use, absorbency and fasteners are more critical. For the plastic cover and scent, a DL may be biased differently than an IC.
To successfully work for a company, one should try to avoid discussing their AB/DL interests, but can show extra enthusiasm for the product. A good employee knows the product, knows their job very well, and seeks to help the company above personal interests. While some people may find my interest in adult diapers odd, my value to the company should keep that from being an issue. I definitely think that we could improve diapers and diaper company profits if we worked for them. The harder question is how good of an employee would we be?
Of course, I do not currently work for a diaper company. The previous statements are only my opinion and do not reflect any experience with diaper companies beyond the DL consumer level. For at least the next decade, I plan to remain in my current career. After that, I have no solid plans for my next career. Currently, bondage gear is higher on my list than diapers, but that may change by the time that I reach that point in my life. Currently, both industries have plenty of room for improvement.
