Automatic Drying Diaper Improves Health Care
Japan is dealing with their problem of aging population by automating health care. This automatic drying diaper could replace catheters and provide extra benefits.
Catheters might be cheaper in the short run but risk infections, are uncomfortable to insert and remove and require some training to insert. This automatic drying diaper requires no training, is much more comfortable with less risk of infection and offers other advantages.
Since there is already some electronics this device could be easily expanded to measure amounts and times, perform tests on the contents to monitor health and help with diagnostics plus alert care givers of needed care.
This is just one of the 15 Alternatives solution types. A diaper that automatically dries itself is an example of Return to Stable, and this one does it multiple times. A disposable diaper is a Single Stable, although not very stable. A catheter is a Multiple Direct, it directly catches urine multiple times. That is only 3 of the possible 15 solution types. There are 12 other types of innovation possible.

Is P vs NP solved?
Vinay Deolalikar from HP Labs claims he may have solved the P vs NP problem proving that P ≠ NP. It’s literally a million dollar problem. Millennium Prize is offering $1,000,000 for the solution. This is very important for a range of problems including: cryptography, logistics, biology, mathematics, and innovation.
If P ≠ NP is true, it would allow a person to formally show that a problem cannot be solved efficiently, so attention could be focused on partial solutions or solutions to other problems. Or as I say in my talks about applying information theory to science, “Being able to prove something is impossible helps you focus on the things that might be possible.”
The other implication is that some problems can be proven to be harder to solve than to test that the solution is true. This is very important to cryptography. If P = NP then many of the encryption methods would be easy to break and would need to be changed.
Hard to solve, easy to check also directly relates to innovation. I run into this all the time. A company has what they believe is an impossible problem. After we apply the Predictive Innovation® and find the solution they think the solution was obvious. It was far easier to check the answer than it was to solve the problem. In fact it was so easy to check the answer they didn’t understand why it was so hard to find in the first place. I would not be surprised if P ≠ NP was proved.
