Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the finger sleeve is made as a deformable constricted structure to adapt to different finger circumferences, then the adaptability is improved, but the finger sleeve cannot be fixed reliably and slips easily on both thin and thick fingers
Solution Approach 1:
The invention divides the finger lamp into separate components: a finger sleeve member and a lamp holder member that can be independently adjusted and assembled. The finger sleeve member has an adjustable inner diameter structure that can be expanded or contracted to fit different finger sizes, while the lamp holder member is separately positioned and fixed on the finger sleeve. This segmentation allows each component to be optimized independently for both adaptability and reliability.
Solution Approach 2:
The invention introduces an adjustable inner diameter structure in the finger sleeve member that can dynamically change its size to adapt to different finger circumferences. The structure includes movable connection mechanisms that allow the finger sleeve to expand or contract, providing a secure fit for various finger sizes while maintaining reliable fixation through adjustable tension.
2Ease of manufacture
If the lamp holder is slidably clamped on the finger sleeve to facilitate assembly, then the ease of assembly is improved, but the lamplight irradiation direction cannot be adjusted
Solution Approach 1:
The lamp holder member is connected to the finger sleeve member through a movable connection mechanism that allows rotational adjustment. This dynamic connection enables the lamp holder to rotate around the finger sleeve, providing adjustable lamplight irradiation direction while maintaining easy assembly through the sliding clamp structure. The movable connection combines the benefits of both simple assembly and directional adjustability.
3Reliability
If the finger sleeve is made tight to prevent slipping on thin fingers, then the fixation reliability is improved, but it becomes too tight and slips off on thick fingers
Solution Approach 1:
The finger sleeve member incorporates an adjustable inner diameter structure that can dynamically adapt to different finger circumferences. The structure includes expandable and contractible elements that allow the sleeve to tighten for thin fingers and loosen for thick fingers, providing reliable fixation across various finger sizes without compromising comfort or adaptability.
Solution Approach 2:
The invention changes the inner diameter parameter of the finger sleeve member to adapt to different finger sizes. By adjusting the inner diameter from a contracted state for thin fingers to an expanded state for thick fingers, the system maintains optimal fixation reliability across different finger circumferences while preserving compatibility with various user types.
