Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If expensive jigs are used to retain and position components during assembly, then assembly accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces the mechanical positioning system (jigs) with a measurement and calculation system. The position measurement device measures actual positions, and the control device calculates correction amounts to compensate for deviations, eliminating the need for complex mechanical retention structures.
Solution Approach 2:
The patent introduces a control device as an intermediary that processes measurement data and generates correction instructions. This intermediary system translates measured position deviations into actionable correction amounts, enabling accurate assembly without direct mechanical intervention.
2Manufacturing precision
If multiple jigs are used to position components, then positioning accuracy is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent extracts the positioning function from the mechanical jigs and transfers it to the measurement and control system. The position measurement device independently measures positions, and the control device independently calculates corrections, separating the positioning function from complex mechanical structures.
Solution Approach 2:
The assembly system performs self-positioning through measurement and calculation. The position measurement device automatically detects deviations, and the control device automatically generates correction amounts, enabling the system to self-correct without external mechanical assistance.
3Manufacturing precision
If traditional jig systems are used to ensure assembly precision, then assembly accuracy is maintained, but cost increases
Solution Approach 1:
The patent replaces expensive, durable jig systems with a more economical measurement and control system. The position measurement device and control device represent a lower-cost alternative to traditional heavy-duty mechanical jigs, achieving the same precision goal at reduced cost.
Solution Approach 2:
The patent substitutes the expensive mechanical jig system with an electronic measurement and calculation system, reducing material costs and device complexity while maintaining or improving assembly precision through active measurement and correction.
