Solution Overview
Problem
Existing bracelet clasps are complex, time-consuming to assemble, and costly to manufacture, with numerous parts that make them difficult to handle.
Innovation Solution
A simplified bracelet clasp design consisting of a single part, a strip with a hinged end and deformable portions, featuring pins and hooks for locking, and optionally a loop or peg for additional guidance and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional unfolding clasp with multiple parts is used, then the locking mechanism is secure, but the assembly is time-consuming and complicated with high manufacturing cost
Solution Approach 1:
The patent merges multiple separate components (base, cover, unfolding arms, hinges, resilient elements) into a single integrated strip component. The strip includes a rigid portion and deformable portions that are formed as one piece, eliminating the need for separate assembly of multiple parts and significantly simplifying manufacturing.
Solution Approach 2:
The single strip component is segmented into functional zones: a rigid portion for structural support and pin engagement, and deformable portions for elastic deformation to enable locking and unlocking. This segmentation allows the single component to perform multiple functions that previously required separate parts.
2Ease of operation
If a traditional unfolding clasp with multiple parts is used, then the locking mechanism is secure, but the clasp is not easy to handle
Solution Approach 1:
By combining all functional elements into a single flexible strip, the clasp becomes easier to handle as it requires no assembly and can be manipulated as one piece. The deformable portions allow the strip to be bent and shaped during operation without requiring separate components.
Solution Approach 2:
The strip transitions from a rigid multi-part structure to a dynamically flexible single component that can deform elastically during operation. The deformable portions enable the strip to bend and flex during locking and unlocking, improving ease of operation.
3Ease of manufacture
If a single-part strip design is used, then manufacturing is simplified and cost is reduced, but the locking mechanism must be redesigned
Solution Approach 1:
The locking mechanism relies on the dynamic elastic deformation of the strip's deformable portions rather than rigid mechanical linkages. When force is applied, the deformable portions bend to engage or disengage pins, providing a simple yet effective locking action that is easier to manufacture than traditional mechanisms.
Solution Approach 2:
The invention changes the physical state and mechanical properties of the strip by introducing deformable portions with specific elastic characteristics. This allows the material to transition between rigid and flexible states during operation, enabling the locking mechanism to function with a single component.
