Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the width of the wearable electronic device is fixed, then the manufacturing process is simple, but the device cannot accommodate diverse user sizes effectively
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed width structure into an adjustable one. The device width can be dynamically changed through a rotating bracket mechanism that allows the temple arms to be repositioned relative to the lens frame, enabling the same device to adapt to different head sizes and shapes.
Solution Approach 2:
The patent segments the device into multiple adjustable components: a lens frame, temple arms, and a rotating bracket mechanism. This segmentation allows independent adjustment of each component's position and angle, providing versatile width adaptation while keeping each individual component relatively simple in design.
2Adaptability or versatility
If an adjustable width mechanism is added, then the device can fit various user head sizes, but the device complexity increases
Solution Approach 1:
The rotating bracket mechanism is designed to be manually operated by the user without requiring external tools or complex procedures. The user can directly rotate the bracket to adjust the width, making the adjustment process self-service and intuitive, thereby maintaining ease of operation despite the added adjustability feature.
3Ease of manufacture
If the device structure is simplified, then the manufacturing is easier, but the device cannot effectively adjust to fit individual head sizes
Solution Approach 1:
The rotating bracket mechanism serves multiple functions: it adjusts the width of the device, secures the temple arms in position, and provides a standardized interface for assembly. This multi-functionality allows a single component to address several requirements, simplifying the overall manufacturing process while maintaining adaptability to different head sizes.
