Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual observation and magnifier confirmation are used to mark defective position points, then marking accuracy can be ensured, but the operation process becomes complicated and productivity decreases
Solution Approach 1:
The patent combines the magnifying function and marking function into a single integrated device. The magnifying component and marking component are merged into one tool, allowing the worker to both magnify and mark defective position points without switching between different tools or performing separate confirmation steps with a magnifier.
Solution Approach 2:
The marking component is designed to automatically align with the magnified target position point through the adjusting component. This preliminary alignment action ensures that the marking is accurately positioned before the actual marking occurs, eliminating the need for post-marking confirmation with a magnifier.
2Ease of operation
If manual observation with naked eyes is used to identify defective position points, then the operation process is simple, but marking accuracy decreases due to potential human error
Solution Approach 1:
The patent combines the magnifying function and marking function into a single integrated device. The magnifying component and marking component are merged into one tool, allowing the worker to both magnify and mark defective position points without switching between different tools or performing separate confirmation steps with a magnifier.
Solution Approach 2:
The magnifying component serves as an intermediary between the worker's naked eye observation and the marking action. It provides optical magnification of the defective position point, allowing the worker to accurately identify the target location while maintaining ease of operation.
3Reliability
If post-marking confirmation with a magnifier is performed, then marking accuracy can be verified, but the operation time increases and productivity decreases
Solution Approach 1:
The marking component is designed to automatically align with the magnified target position point through the adjusting component. This preliminary alignment action ensures that the marking is accurately positioned before the actual marking occurs, eliminating the need for post-marking confirmation with a magnifier.
Solution Approach 2:
The magnifying component provides real-time visual feedback of the target position point during the marking process. The worker can observe the magnified view and confirm the accuracy of the marking position before completing the marking action, ensuring reliability without requiring separate post-marking verification.
