Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic components (energy storage, information transmission, optical sensors) are integrated into a smart ring for rotation and motion detection, then the device functionality is improved, but the device complexity and space arrangement difficulty increase
Solution Approach 1:
The patent implements nesting by placing the detection module inside the case, which is integrated into the smart ring structure. The optical identification assembly, energy storage unit, and information transmission unit are all nested within the confined space of the ring, with each component arranged in a nested configuration to maximize space utilization while maintaining functionality.
Solution Approach 2:
The patent divides the smart ring into distinct functional modules: a case containing the detection module, separate installation areas for energy storage and information transmission units, and an optical identification assembly with dedicated optical paths. This segmentation allows each component to be independently designed and positioned to optimize performance within the limited space.
2Ease of operation
If the wearable device is made small for comfortable wear during sleep, then the comfort is improved, but the space for electronic components is reduced
Solution Approach 1:
The patent employs a flexible circuit board as the base for mounting electronic components, allowing the device to conform to the contours of the finger or wrist. This flexible substrate enables the smart ring to maintain a thin, comfortable profile while still accommodating necessary electronic components through optimized layering and routing.
Solution Approach 2:
The patent utilizes vertical stacking and multi-layer arrangement of components on the circuit board to accommodate electronic elements in the third dimension rather than spreading them out horizontally. This dimensional approach allows sufficient component integration while maintaining a compact outer profile suitable for comfortable wear.
3Measurement precision
If the optical identification assembly is equipped with lens units and sheltering units for precise optical detection, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent combines the optical emitter, optical receiver, lens unit, and first sheltering unit into a single integrated optical identification assembly. This merging of multiple optical components into one unified module achieves precise optical detection functionality while reducing the number of separate parts, simplifying assembly, and minimizing the overall space required for the optical system.
