I guess I am not your target market, but as far as I am concerned, this is a problem that has been solved. A suitcase is a box for moving your stuff around. It needs to be
- Relatively durable (to protect your stuff)
- Relatively lightweight (so you can take more stuff)
- Relatively secure (so nobody takes your stuff)
- A telescoping handle and 2 or 4 wheels are table stakes
Where are you hoping to innovate?
I use a 22" consumer-level TravelPro that is more than 8 years old. It was <$100 in 2010. It looks ugly and the handle sticks a little, but I have checked it more than 500 times in the last 3.5 years and it still works fine. Before that I had some off-brand soft-sided spinner from my local dept store that lasted more than 10 years (and I still use sometimes if my wife and I are traveling together).
