Watch Switch Buffering Structure for Impact-Protected Screw Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switch devices in wristwatches fail to effectively buffer external impacts, leading to potential damage to the male and female screw sections when the operation member is locked and subjected to external forces.
Innovation Solution
A switch device with a cylindrical member and operation member design that includes a buffering member with projections to absorb and distribute external impacts, ensuring the operation member is slidable and rotatable while preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operation member is locked in the pipe to prevent damage from external impacts, then reliability is improved, but the screw sections become vulnerable to damage when subjected to external forces
Solution Approach 1:
The patent applies beforehand cushioning by introducing a buffering member with elastic properties that is pre-positioned between the operation member and the pipe. When external impacts occur, this buffering member compresses and absorbs the shock energy before it can reach the screw sections, thereby protecting them from damage while maintaining the locked state for reliability.
2Stability of the object's composition
If a locking mechanism is used to secure the operation member, then stability is improved, but the structure becomes more complex
Solution Approach 1:
The patent merges the buffering function with the locking mechanism structure. The buffering member is integrated into the assembly between the operation member and the pipe, combining shock absorption and locking functions into a unified structure. This reduces overall device complexity while maintaining both stability and protection capabilities.
3Ease of operation
If the operation member is designed to be slidable and rotatable, then ease of operation is improved, but vulnerability to external impacts increases
Solution Approach 1:
The patent introduces the buffering member as an intermediary element between the movable operation member and the fixed pipe structure. This intermediary absorbs and dissipates impact forces, allowing the operation member to maintain its slidable and rotatable mobility for ease of operation while being protected from harmful impact forces transmitted through the structure.
