Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wearable device applies external force to assist user movement, then the user's movement capability is improved, but the device requires complex control mechanisms to adjust force dynamically
Solution Approach 1:
The wearable device incorporates sensors that detect user movement parameters and feed this information back to the control system. The processor analyzes the feedback data and dynamically adjusts the external force applied by the driving module, creating a closed-loop control system that adapts to user needs in real-time without requiring complex manual intervention
Solution Approach 2:
The device autonomously monitors user movement through integrated sensors and automatically adjusts the assistance or resistance force without external input. The system serves itself by using its own sensor data to control its actuating mechanisms, eliminating the need for complex user-side control interfaces
2Productivity
If the wearable device provides real-time feedback and dynamic adjustments, then exercise effectiveness is improved, but power consumption increases
Solution Approach 1:
The device performs sensing, processing, and actuation in periodic cycles rather than continuously. The processor evaluates sensor data at specific intervals and adjusts driving module parameters accordingly, reducing overall power consumption while maintaining effective real-time control during exercise sessions
Solution Approach 2:
The system dynamically changes operational parameters such as sampling frequency and processing intensity based on exercise intensity and user needs. During high-intensity exercise, the device increases monitoring and adjustment frequency, while during low-intensity periods, it reduces power consumption by lowering operational parameters
3Measurement precision
If the device measures torque and evaluates movement in real-time, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The torque sensor module serves multiple functions: it measures torque for evaluation, provides feedback for control adjustments, and monitors user exertion levels. This multi-functionality reduces the need for separate dedicated sensors for each measurement task, thereby reducing overall device complexity while maintaining high measurement precision
Solution Approach 2:
The patent integrates the torque sensor module directly into the driving module assembly, combining sensing and actuation functions in a unified structure. The processor handles both torque measurement and movement evaluation in a single integrated control system, reducing complexity compared to separate independent systems
