Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the clamping force is increased to prevent the device from falling, then the reliability is improved, but the wearing comfort deteriorates
Solution Approach 1:
The bracket employs a rotating component that allows dynamic adjustment of the angle between the first and second segments. This enables the clamping force to be modified according to different usage scenarios and user needs, resolving the contradiction between device stability and wearing comfort by making the clamping force adaptable rather than fixed
Solution Approach 2:
The patent changes the geometric parameter (angle) between the bracket segments through rotation, which directly affects the clamping force. By adjusting this angular parameter, the system can provide different clamping forces for different scenarios, simultaneously achieving reliable fixation and comfortable wear
2Ease of operation
If the clamping force is decreased to improve wearing comfort, then the ease of operation is improved, but the reliability deteriorates
Solution Approach 1:
The rotating component enables the bracket to dynamically adjust its configuration. Users can rotate the component to change the angle between segments, thereby adjusting the clamping force to an appropriate level for comfortable wear while maintaining sufficient device stability through proper angle selection
Solution Approach 2:
By changing the angular parameter of the bracket segments through rotation, the system can reduce clamping force to improve comfort while maintaining reliability through optimized geometric configuration, allowing both comfort and stability to coexist
3Device complexity
If the angle between bracket segments is fixed, then the device complexity is reduced, but the adaptability deteriorates
Solution Approach 1:
The rotating component introduces a simple dynamic mechanism that allows the bracket angle to be adjusted. This adds minimal complexity while significantly improving adaptability, enabling the device to accommodate different head shapes and usage scenarios through a straightforward rotational adjustment
Solution Approach 2:
The bracket is divided into multiple segments (first segment and second segment) connected by a rotating component. This segmentation allows independent adjustment of each segment's angle, providing adaptability for different head shapes while keeping the overall structure relatively simple and modular
