Eyeglasses Temple Coupling Latch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglasses assemblies face issues with accidental detachment of temple units from the rim unit, especially when subjected to impact or pressure, which affects the user's experience and the durability of the eyewear.
Innovation Solution
The eyeglasses assembly incorporates a latch member that moves between a closed and open position, preventing accidental separation of the temple members from the rim unit by engaging with specific groove sections on the coupling members, ensuring secure attachment and easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connecting member is allowed to slide freely along the guiding groove for easy replacement, then the ease of operation is improved, but the reliability deteriorates as the temple unit may accidentally detach when impacted or pressed
Solution Approach 1:
The guiding groove is segmented into two distinct sections: a first groove section that permits sliding movement for easy replacement, and a second groove section that limits movement to prevent accidental detachment. This segmentation allows the connecting member to have different movement characteristics in different zones of the same groove, resolving the contradiction between ease of replacement and attachment stability.
Solution Approach 2:
The groove structure transitions from a static, uniform guiding groove to a dynamic structure with two functional zones. The first groove section allows dynamic sliding motion for replacement operations, while the second groove section provides static positioning to prevent accidental detachment during normal use, making the system's behavior adaptive to different operational states.
2Reliability
If a latch mechanism is added to prevent accidental detachment, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The latch function is merged with the guiding groove structure itself, eliminating the need for a separate latch mechanism. The two-section groove design integrates the attachment prevention function directly into the existing guiding structure, maintaining reliability while avoiding additional complexity from separate components.
Solution Approach 2:
The dual-section groove structure provides self-latching functionality through its geometry alone. The connecting member automatically engages with the second groove section's limiting structure without requiring external actuation or additional locking components, achieving reliable attachment prevention through the structure's own design rather than auxiliary mechanisms.

AI summary
An eyeglasses assembly includes a rim unit, two temple members, and two coupling units interconnecting the temple members and the rim body. The coupling unit includes a first coupling member that has a slide groove including a non-limiting and a limiting groove section, and a second coupling member that engages the non-limiting and limiting groove sections to permit and prevent separation of the first and second coupling members, respectively. The coupling unit further includes a latch member movably mounted to the first coupling member and movable between a closed position and an open position that respectively prevents and permits the movement of the second coupling member into the non-limiting groove section.
