Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional handheld devices are used without specialized knowledge, then ease of operation is improved, but reliability and safety deteriorate due to incorrect operation
Solution Approach 1:
The patent implements feedback mechanisms through sensors that monitor operational parameters (torque, rotation angle, current) and provide real-time information to both the control unit and the user via display or warnings. This allows users without specialized knowledge to operate devices safely by receiving guidance and alerts about abnormal conditions, thus improving reliability while maintaining ease of operation.
Solution Approach 2:
The device performs self-monitoring and self-regulation through integrated sensors and control units that automatically detect abnormal operating conditions and trigger warnings or shutdowns. This self-service capability ensures reliable operation without requiring specialized user knowledge, as the device protects itself from misuse.
2Adaptability or versatility
If modular components with universal bus connection are used, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent employs a universal bus connection system that enables multiple different components (sensors, actuators, display units) to communicate with the control unit through a standardized interface. This universality allows the same communication backbone to support various functional modules, improving adaptability while managing complexity through standardization rather than requiring unique communication protocols for each component.
Solution Approach 2:
The device is divided into modular segments (processing and drive unit, power supply unit, detection unit, control unit) that can be independently designed, manufactured, and replaced. Each segment communicates through the universal bus, allowing flexibility in configuration while distributing complexity across independent modules rather than requiring a monolithic complex system.
3Reliability
If multiple sensors and control units are integrated, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensors (torque sensor, rotation angle sensor, current sensor) and control functions into an integrated system where all components connect to a central control unit through the universal bus. This merging approach improves reliability through comprehensive monitoring while managing complexity by consolidating control logic in one unit rather than distributing it across multiple independent control systems.
