Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple connectors are added to the light source to accommodate different manufacturers' cables, then mechanical compatibility is improved, but ergonomics deteriorate due to protruding elements and light power is lost due to poor positioning
Solution Approach 1:
The patent implements a universal connection device with a single recess that can accommodate multiple types of connectors (first, second, and third types) from different manufacturers. The recess is designed with specific geometric features that can mechanically engage with various connector types, allowing one light source to work with multiple cable manufacturers without adding protruding elements, thus maintaining ergonomics while achieving compatibility.
2Adaptability or versatility
If multiple connectors are added to the light source to accommodate different manufacturers' cables, then mechanical compatibility is improved, but light power is lost due to poor positioning of the cable interface
Solution Approach 1:
The connection device features a precisely engineered recess with specific geometric constraints that ensure the distal end of any compatible connector is positioned at a predetermined optimal location relative to the light source. This universal design accommodates multiple connector types while maintaining consistent positioning, preventing light power loss that would occur with poor positioning.
Solution Approach 2:
The recess acts as an intermediary structure that mediates between the light source and various connector types. It provides a standardized interface that translates different connector geometries into a uniform positioning arrangement, ensuring that regardless of which connector type is used, the optical alignment and light power transmission remain optimal.
3Ease of operation
If a single connection device is used for all cable types, then ergonomics are improved by eliminating protruding elements, but mechanical compatibility becomes challenging
Solution Approach 1:
The connection device employs a universally compatible recess design that can mechanically engage with multiple connector types (first, second, and third types) from different manufacturers. The recess incorporates geometric features such as specific wall angles, depth dimensions, and engagement surfaces that can accommodate the varying geometries of different connectors, achieving compatibility without requiring multiple protruding connectors.
