Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mechanical attachment methods are used to connect temple arms to lens frame, then structural strength is improved, but reversing orientation becomes complex and requires additional mechanical components
Solution Approach 1:
The patent replaces traditional mechanical attachment methods (screws, clips, or hinges) with a magnetic attachment system. Magnets embedded in the temple arms and lens frame create secure attachment without complex mechanical reversing mechanisms, allowing simple orientation changes while maintaining strong connection.
2Ease of operation
If magnetic attachment is used to facilitate temple arm reversal, then ease of operation is improved, but retention strength may be insufficient without additional locking mechanisms
Solution Approach 1:
The magnetic attachment system is divided into multiple magnet segments distributed across the temple arms and lens frame. This segmentation provides multiple attachment points that collectively deliver strong retention force while maintaining ease of reversal through simple orientation changes.
3Adaptability or versatility
If reversible orientation mechanism is added to allow temple arm flipping, then adaptability is improved, but device complexity increases due to additional hinges and locking components
Solution Approach 1:
The patent eliminates complex hinge and locking mechanisms by using magnetic attraction and repulsion forces. The magnets are positioned to naturally guide the temple arms into correct orientations through magnetic alignment, providing versatile orientation changes without additional mechanical complexity.
4Reliability
If multiple magnets are used to enhance magnetic retention, then retention strength is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The magnetic system uses multiple smaller magnet segments instead of large magnets. These segmented magnets are easier to manufacture and position during assembly, while collectively providing the required retention strength through distributed magnetic forces across multiple attachment points.

AI summary
Reversible orientation eyewear for which each of the temple arms moves from an initial orientation relative to the lens frame to a reverse orientation relative to the lens frame by undergoing movements that include rotating a locking piece from the one of the two relative positions to the remainder of the two relative positions and thereby becoming free of magnetic attraction by the magnetically attractive elements; pivoting the temple arms about associated ones of the two ends of the lens frame; and rotating the locking piece from the remainder of the two relative positions to the one of the relative positions to restore magnetic attraction by the magnetically attractive elements.
