Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the foot step is made more robust to handle overloading, then the strength and durability are improved, but the device complexity and cost increase
Solution Approach 1:
The load detection device detects overload conditions before they cause damage to the foot step. The controller receives load signals and judges whether the foot step is overloaded, triggering an alarm before the excessive load can fracture or damage the foot step structure.
Solution Approach 2:
The system implements a feedback loop where the load detection device continuously monitors the load on the foot step, the controller processes the load signals and compares them against safe thresholds, and the alarm provides immediate feedback to users when overload conditions are detected, enabling them to take corrective action.
2Reliability
If load detection and alarm systems are added to the foot step, then the reliability and safety are improved, but the device complexity increases
Solution Approach 1:
The load detection device and controller are configured to detect and judge overload conditions before they can compromise the foot step's reliability. By implementing preliminary detection and alerting mechanisms, the system maintains high reliability through preventive monitoring rather than requiring overly robust structural design.
3Duration of action of stationary object
If the foot step is designed to be more durable against overloading, then the service life is extended, but the device complexity and initial cost increase
Solution Approach 1:
The load detection device performs preliminary detection of overload conditions before they can cause cumulative damage that would reduce the foot step's service life. The controller continuously monitors load signals and triggers alarms to prevent users from applying excessive loads that would accelerate wear and degradation.
Solution Approach 2:
The alarm system provides continuous feedback to users about the load status of the foot step, enabling them to adjust their usage patterns and avoid behaviors that would reduce service life. This feedback mechanism extends the operational lifespan of the foot step by preventing repeated overload exposure.
