How to add suspension to a food trolley to prevent spillage of food and tea?
One of the biggest problems with current models is that when they go over the slightest bump or carpet runners/plates e.g. and they will spill and tip whatever is on them. This is a massive problem if the user is carrying hot tea or their dinner, increasing clean up work and generally reducing the quality of life of the user. I cannot think of a relevant method for stabilising the food tray/drink holder without drastically reducing the overall function and massively increasing cost while still allowing the trolley to support the user while they take their food from the prep area/kitchen to the eating area.
A few Ideas I have had:
large pneumatic wheels (solid rubber in most other examples), Some sort of spring suspension, Pistons, A counter weight... I have tried researching stabilisers for cameras but they don't seem to be relevant. Help with research keywords would also be useful as its difficult to know what to look up.
Another problem I'm addressing is the aesthetics of the product as most examples just look like hospital equipment not everyday furniture. Currently I am siding on wood as the main material for the frame, If anybody has suggestions that would be better than boring tubular steel I am still in the early stages of development and would appreciate inspiration!
