Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional strap adjustment mechanisms are used, then the device can be worn, but the tightness adjustment accuracy is low and multiple operations are required
Solution Approach 1:
The patent implements a feedback mechanism where the controller measures the overlapping length of the two strap bodies using a length measurement mechanism, compares it with the target overlapping length, and controls the tightness adjustment mechanism to adjust the overlapping length accordingly. This closed-loop feedback system ensures accurate tightness adjustment with minimal user operations.
Solution Approach 2:
The system performs self-adjustment by automatically controlling the tightness adjustment mechanism based on the measured overlapping length and target value. The controller autonomously determines the required adjustment and executes it, reducing the need for multiple manual operations by the user.
2Reliability
If manual adjustment operations are repeated multiple times, then appropriate tightness can be achieved, but user time is wasted
Solution Approach 1:
The system performs preliminary measurement of the overlapping length before adjustment, allowing the controller to calculate the exact adjustment needed in advance. This preliminary action prevents unnecessary trial-and-error operations, ensuring reliable tightness adjustment while minimizing the time required.
Solution Approach 2:
The continuous feedback loop measures the current overlapping length, compares it with the target value, and automatically adjusts the strap tightness. This real-time feedback eliminates the need for repeated manual operations, reducing adjustment time while maintaining high reliability.
3Measurement precision
If the overlapping length is precisely controlled, then tightness accuracy is improved, but the device complexity increases
Solution Approach 1:
The controller serves multiple functions: it controls the tightness adjustment mechanism, measures the overlapping length using the length measurement mechanism, compares measurements with target values, and executes adjustments. This multi-functionality reduces the need for separate dedicated components, achieving precise overlapping length control without proportionally increasing device complexity.
Solution Approach 2:
The patent combines the control function, measurement function, and adjustment execution function into an integrated system. The controller merges multiple functions that could be separate components, while the tightness adjustment mechanism integrates the adjustment actuation with the overlapping length control, achieving precision without excessive complexity.
