Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnet connection is used to combine primary and secondary eyeglasses, then the combination is achieved automatically through magnetic attraction, but the structure becomes too hypertrophy and the application field is too narrow (only suitable for metal frames)
Solution Approach 1:
The patent extracts the magnetic connection mechanism from the nosepiece structure, replacing it with a plug connection system. The plug connector is inserted into a plughole defined in the primary nosepiece, eliminating the need for magnets and magnetic holes. This extraction allows the nosepiece to be simplified and makes the assembly applicable to both metal and plastic frames.
Solution Approach 2:
The plug connection mechanism serves multiple functions: it provides structural support, enables easy assembly and disassembly, and is universally compatible with different frame materials (metal and plastic). The plughole and plug connector design allows the same mechanism to work across various eyeglass types without modification.
2Stability of the object's composition
If multiple nosepieces (primary, secondary, additional) are used with magnets for combination, then the positioning is achieved, but the device complexity increases and the assembly becomes too heavy
Solution Approach 1:
The patent merges the functions of multiple nosepieces into a single integrated primary nosepiece structure. The plug connector integrates the positioning and connection functions that were previously distributed across multiple separate nosepiece components. This merging reduces the total number of parts and simplifies the overall assembly.
Solution Approach 2:
The nosepiece is segmented into functional zones: the plughole defined in the primary nosepiece and the plug connector on the secondary nosepiece. This segmentation allows for independent optimization of each component while maintaining their functional relationship, reducing overall complexity.
3Force
If magnets are installed in the lower portion of magnetic holes with upper portion empty, then the combination is achieved, but the primary nosepiece and additional nosepiece become too hypertrophy
Solution Approach 1:
The patent extracts the magnetic components entirely from the nosepiece structure, replacing them with a mechanical plug connection system. This extraction eliminates the need for magnetic holes and the space they occupy, significantly reducing the nosepiece size and complexity while maintaining connection functionality.
4Ease of operation
If hook connection is used where a hook on secondary nosepiece hooks the primary nosepiece, then the combination is achieved, but the structure becomes cumbersome and limited in application
Solution Approach 1:
The plug connection mechanism is designed to be universally applicable across different frame types and materials. The plughole and plug connector can accommodate both metal and plastic frames, unlike the hook connection which is limited in its application scope and becomes cumbersome in implementation.
5Strength
If outer spring snap connection is used with spring snaps trapping or clasping the primary nosepiece, then the combination is achieved, but the structure becomes cumbersome and not suitable for metal frames
Solution Approach 1:
The plug connection mechanism provides universal compatibility with both metal and plastic frames. The rigid plug connector and plughole design can withstand the connection requirements for metal frames, while also working effectively with plastic frames, eliminating the frame type limitations of spring snap connections.
