Engineering Contradiction Analysis
1Adaptability or versatility
If advanced electronics and power sources are integrated into a smart ring, then functionality is enhanced, but device size and manufacturing complexity increase
Solution Approach 1:
The patent implements nesting by placing the curved power source, circuit board with electronic components, and sensor array within the hollow interior cavity of the ring body. The power source is positioned in the central region, with the circuit board and sensors arranged around it, creating a nested configuration that maximizes space utilization while maintaining functionality.
Solution Approach 2:
The patent employs curvature by designing the power source with a curved surface that conforms to the interior geometry of the ring. This curved design allows the power source to fit efficiently within the circular cross-section of the ring, optimizing space utilization and simplifying the overall manufacturing process by following the natural geometry of the wearable device.
2Adaptability or versatility
If multiple sensors and electronic components are added, then user data collection capability improves, but the internal space required increases
Solution Approach 1:
The patent applies local quality by strategically positioning different sensor types at specific locations around the ring's interior circumference. The sensor array includes temperature sensors, accelerometers, and other detectors arranged to optimize their measurement capabilities while minimizing overall space requirements. Each sensor is placed where it can most effectively perform its specific function.
Solution Approach 2:
The circuit board integrates multiple electronic functions including power management, data processing, wireless communication, and sensor interfacing into a single compact component. This multi-functional approach consolidates what would otherwise require separate components, significantly reducing the total internal space needed while maintaining comprehensive data collection capability.
