This bradidea comes to us from cousin Sarah G. The problem statement is: After wearing nylons/stockings all day in warm weather, or just wearing them with warm shoes, at the end of the day your sweaty feet make for an unpleasant ripeness when you disrobe.
The idea: Integrate an “Odor Eater” (or Dr. Scholl’s) style foot odor absorbing pad into the feet of the nylons. Alternatively, make the sole out of a more permeable material to improve airflow that will work with an existing Odor Eater that is in the shoe but not attached to the hose. The value added comfort would likely be a big selling point in higher-end product lines. The key challenges will likely be figuring out how to keep costs down and keep the entire product washing machine safe while maintaining the odor absorbing effectiveness of the insole.
This is another one from my brother Jason. He is taking a well-thought-out page from the cash register tape people or check-book “It’s time to reorder” reminder people, where when you are near the end of the roll of toilet paper (TP), you are reminded the end is nigh.
The idea is simple, color the last few sheets of TP on each roll a little differently, maybe light pink like Kleenex does? Or even just a colored stripe down one side of the last few sheets like the cash register tape? A value-added feature would be to add some reminder text like “The end is nigh! Make sure next roll is within arm’s reach!”
This idea would hopefully help reduce the number of embarrassing times where you have to yell out from the bathroom asking your wife to grab a package of TP from the storage closet downstairs.
Key Design Concepts: The color additive must not impact people with skin sensitivity. The reminder message should be appropriately localized and/or in multiple languages. Bonus might be a count of sheets remaining on the roll every 50 or so sheets to indicate just how much time you have left as opposed to guessing based on roll thickness.
This idea came to us via my brother Jason during Christmas dinner, and is a great one. Basically make the cardboard center roll for toilet paper out of some steam-resistant water-soluble material that would dissolve near instantly in water. When you are done with the last piece of paper, you just throw the roll tube in the toilet saving landfill and garbage space, or composting space if your town supports it.
Or, expanding on the idea, why not eliminate the cardboard center tube entirely? If you make the center of the roll just slightly bigger than the standard holder size (about 3/4 inch), the structure of the roll would likely stay intact until very near the last sheet, which is always ruined by the glue that holds it to the cardboard anyway. The added benefit is that you can fit more toilet paper per roll, reducing shipping costs. If the manufacturing requires a structure to be in place to support the center of the roll, some small compostable grommet could be used, and would be popped out by the roll holder when the roll is installed.
Addendum: Apparently the first part of this one has been tried, making the second option moot:
I disagree with the article’s point, and the third option above (no roll center tube) should still be kept on the table.
