Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated suction portion is manufactured for each application, then the suction performance and reliability are improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The suction portion is designed with a universal structure that can be used across different applications without dedicated manufacturing for each case. The invention uses a standard化的 suction component that maintains reliable suction performance while eliminating the need for custom manufacturing, thereby reducing device complexity and manufacturing cost.
2Reliability
If a dedicated suction portion is manufactured for each application, then the suction performance is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The invention employs a universal suction portion design that can be manufactured using standard processes and applied to multiple applications. This eliminates the need for dedicated manufacturing for each application, significantly improving ease of manufacture while maintaining suction performance through proper design of the universal component.
3Measurement precision
If the suction portion is monitored while holding an object, then the deterioration detection accuracy is improved, but the operational time and productivity are reduced
Solution Approach 1:
The invention performs deterioration detection by monitoring the suction portion in a state where it is not holding an object, which is a preliminary check before actual operation. This allows for accurate assessment of the suction portion's condition without interrupting operational time, as the detection can be performed during idle periods or before the suction portion is put into service.
4Ease of operation
If the suction portion is monitored in a static state, then the measurement simplicity is improved, but the detection comprehensiveness may deteriorate
Solution Approach 1:
The invention performs deterioration detection in a static state where the suction portion is not holding an object, simplifying the measurement process. By conducting the assessment before operation, the system ensures that the suction portion is properly positioned and prepared, allowing for simple yet comprehensive detection of potential deterioration without the complexity of monitoring during active operation.
