Background:
Most kitchens contain a countertop and overhead cabinets. The doors on these cabinets generally swing open.
The issue:
An unlucky individual may stand up underneath one of these open cabinet doors and injure themselves on the edge.
Although this situation may seem unlikely, it can arise when a person bends over to pick up something that has fallen onto the kitchen floor (Figure 1).

Fig. 1: This hapless kitchen dweller has forgotten that the kitchen cabinet is open, and has stood up directly into it. Ouch!
Proposal:
A few potential fixes are immediately obvious:
- Cabinet doors could be removed entirely. They are generally only there for aesthetic purposes anyway!
- Sliding doors could be used. However, this usually means that only half of the cabinets can be open at one time, and sliding doors have their own issues.
- The edges of each cabinet door could be padded with foam. This would reduce cabinet-collision injury.
- Each cabinet door could be constructed out of gingerbread, so that it would safely crumble away upon contact with a person’s head.
Each of these fixes has some downsides. But the ultimate solution is both durable and visually indistinguishable from a regular cabinet: a “multi-panel safety door” in which multiple pieces of wood are loosely connected by springs (Figure 2).
If a person hits their head one one of the panels, they’ll just feel a slight amount of force as the spring compresses (and the piece of wood is pushed out of the way).

Fig. 2: A) The “multi-panel ‘safety’ door” is outwardly identical to a regular cabinet door. B) This “X-ray” view of the safety door shows that it is actually four separate pieces connected by springs: a “primary” part in the top left (red / brown) and three separate wooden edge pieces (blue and green). These edge pieces are loosely connected: if a person hits their head on the edge, the force will compress the springs a bit (and the edge piece will move inward), but the person will not be decapitated.
Conclusion:
After I patent this idea, you should amend your city’s residential building code to mandate this style of cabinet door. It’s the only safe option!
PROS: Reduces accidental kitchen decapitations, thus saving health care costs.
CONS: These complicated doors would probably require occasional maintenance.
