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 functions and take measurements, but the device becomes bulky and intrusive
Solution Approach 1:
The patent places multiple functional components (sensors, circuitry, battery) within the hollow interior space of the ring structure, nesting them efficiently to maximize functionality while maintaining a compact form factor that fits on the finger
Solution Approach 2:
The patent utilizes the third dimension by creating a three-dimensional ring structure with internal hollow space, allowing components to be arranged in multiple layers and positions within the ring's volume rather than spreading them out in a planar configuration
2Ease of operation
If the wearable device is made compact and minimal, then it is comfortable for extended wear, but it limits the number of measurements and functions the device can perform
Solution Approach 1:
The patent employs a flexible printed circuit board that can be bent and shaped to fit the contours of the ring structure, allowing multiple components to be mounted on a flexible substrate that conforms to the compact ring geometry without rigid structural constraints
Solution Approach 2:
The ring structure is designed with flexible materials and joints that allow it to adapt to different finger sizes and movements, maintaining comfort during various activities while providing stable mounting for functional components
3Ease of operation
If the device housing is made transparent to allow component access through windows, then data transmission and battery recharge are facilitated, but the structural integrity and sealing are compromised
Solution Approach 1:
The patent implements windows only in specific localized areas of the housing where functionality is required (for sensors, data transmission, and charging), while the rest of the housing maintains full structural integrity and sealing, creating different optical properties only where necessary
Solution Approach 2:
The patent uses transparent or translucent housing material as an intermediary that allows light and electromagnetic signals to pass through while still providing physical protection and structural support, bridging the need for both accessibility and protection
