Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the glasses frame bridge is designed to be thin, then the glasses become lighter and more comfortable, but the bridge portion becomes vulnerable to bending and twisting under external force
Solution Approach 1:
The bridge portion is divided into multiple segments: the original thin bridge frame and a separate coupling bridge component. This segmentation allows the bridge frame to remain lightweight while the coupling bridge provides additional structural support when needed, resolving the contradiction between weight and strength.
Solution Approach 2:
The coupling bridge is made of elastic material that is different from the glasses frame material, creating a composite structure. This composite approach allows the bridge portion to have both the lightweight characteristic of the original frame and the enhanced strength provided by the elastic coupling bridge material.
2Device complexity
If the nose pad is assembled as an integral part of the glasses frame, then the structure is simpler and more durable, but the nose pad becomes difficult to replace when dirty or damaged
Solution Approach 1:
The nose pad assembly is segmented into separate components: the nose pad itself and the coupling bridge it attaches to. This segmentation allows the nose pad to be easily removed and replaced by detaching it from the coupling bridge, while the coupling bridge remains part of the durable glasses frame structure.
Solution Approach 2:
The nose pad is extracted from the integral glasses frame structure and attached to the coupling bridge instead. This extraction allows the nose pad to be independently replaced without affecting the durability of the main frame structure, resolving the contradiction between assembly simplicity and ease of repair.
3Strength
If the coupling bridge is detachably coupled to the glasses frame bridge, then the rigidity is improved and deformation is prevented, but the device complexity increases
Solution Approach 1:
The coupling structure is segmented into distinct components with specific functions: protrusions on the glasses frame bridge that fit into grooves on the coupling bridge, and vice versa. This segmentation allows for a modular assembly that provides enhanced rigidity while keeping the coupling mechanism relatively simple and manageable.
Solution Approach 2:
The coupling bridge extends in a direction perpendicular to the main glasses frame bridge, adding a dimensional aspect to the connection. This dimensional approach allows the coupling bridge to provide rigidity in multiple directions while maintaining a relatively simple two-dimensional coupling interface between the components.
