AI Technical Summary
Existing spring structures suffer from problems such as uneven stress distribution, low material utilization, easy rebound, large space occupation, and insufficient dynamic stability. They cannot maintain a compressed state for a long time and require an external locking mechanism.
The design incorporates a variable-diameter compressible spring structure with self-locking mechanisms at both ends, such as self-locking brackets or self-locking hooks. The diameter variation and self-locking mechanisms prevent rebound and maintain the compressed state.
By using a variable diameter design to achieve uniform stress distribution, weight is reduced, space occupancy is minimized, lifespan is increased, springback is prevented, dynamic stability is enhanced, and no external locking mechanism is required.
