Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch area or button structure is arranged on the outer surface of the smart ring, then control instructions can be sent to interact with electrical devices, but the structural complexity increases, manufacturing costs increase, and the smart ring becomes inconvenient to operate due to its small size
Solution Approach 1:
The patent replaces traditional mechanical button structures and touch areas with a vibration sensor-based control system. The vibration sensor detects tapping or shaking gestures of the finger to generate control instructions, eliminating the need for physical buttons or touch interfaces on the ring surface. This substitution simplifies the structure while maintaining ease of operation through gesture-based control.
2Measurement precision
If a round inner hole is used in the smart ring, then the structure is simple, but the gap between the smart ring and finger increases, leading to inaccurate data measurement
Solution Approach 1:
The patent applies local quality by providing a non-round inner hole structure that matches the specific shape of the finger. Instead of a uniform round hole, the inner hole is designed with varying dimensions to conform to the finger's cross-sectional shape at different locations. This ensures tight contact between the smart ring and finger surface, eliminating gaps and improving sensor measurement accuracy without requiring complex external adjustments.
3Adaptability or versatility
If the smart ring size is increased to accommodate more sensors and electronic components, then functionality is improved, but the smart ring becomes uncomfortable to wear and less aesthetic
Solution Approach 1:
The patent merges multiple electronic components and sensors onto a single circuit board that is integrated into the smart ring structure. By combining the vibration sensor, inertial sensor, wireless communication module, and other electronic components on one compact circuit board, the patent achieves high functionality while minimizing the overall size and weight of the smart ring, ensuring comfort and aesthetics.
4Adaptability or versatility
If the smart ring size is increased to accommodate more sensors and electronic components, then functionality is improved, but manufacturing cost and structural complexity increase
Solution Approach 1:
The patent employs a nested structure where the circuit board with all electronic components is placed inside the annular accommodating cavity of the smart ring body. The inner hole structure is nested within the ring, and the finger fits within the inner hole. This nested arrangement allows multiple functional elements to be compactly integrated without increasing external dimensions or structural complexity.
