Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wearable electronics are made functional with multiple components and features, then the device can perform various measurements and functions, but the device becomes bulky and intrusive
Solution Approach 1:
The patent places multiple functional components (photodetectors, LEDs, batteries, antennas) within the nested structure of the ring device, with components arranged in concentric layers and integrated into the ring's cross-sectional structure, allowing multiple functions in a compact volume
Solution Approach 2:
The patent utilizes the cross-sectional area of the ring (radial and tangential dimensions) to arrange components, rather than expanding the ring's circumference or length, thereby adding functionality without increasing the device's volume or intrusiveness
2Ease of operation
If wearable electronics are made compact and comfortable, then the device can be worn for extended periods, but the device may lack sufficient functional capabilities
Solution Approach 1:
The patent employs flexible printed circuit boards to mount components, allowing the device to conform to the finger's shape and move comfortably with the wearer, while still supporting multiple functional components through the flexible circuit's integrated circuitry
Solution Approach 2:
The patent designs the ring with flexible materials and structures that can dynamically adapt to the wearer's finger movements and deformations, maintaining comfort during extended wear while preserving functional integrity through flexible electrical connections
