Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual positioning of bars and suction cups is used, then device complexity is reduced, but positioning precision deteriorates due to lack of feedback
Solution Approach 1:
The patent implements a feedback mechanism by equipping bars and suction cups with sensors that detect binary codes positioned on the work surface. This provides real-time positioning information to the control unit, enabling operators to verify correct positioning without complex automatic positioning systems. The feedback resolves the contradiction by maintaining simple manual positioning while achieving accurate placement through informational feedback.
Solution Approach 2:
The patent replaces complex mechanical positioning systems with an optical-information based system. Instead of using bulky motors and carriages for automatic positioning, the invention uses binary codes and optical sensors to provide positioning feedback, substituting mechanical complexity with a simpler optical detection mechanism.
2Measurement precision
If magnetic or magnetostrictive measuring systems are used, then positioning feedback is improved, but device complexity worsens due to bulky wiring
Solution Approach 1:
The patent substitutes magnetic and magnetostrictive measuring systems with an optical binary code system. The binary codes positioned on the work surface and read by optical sensors eliminate the need for complex wiring associated with magnetic systems, achieving positioning feedback through a simpler optical mechanism.
Solution Approach 2:
The patent introduces binary codes as an intermediary medium for positioning information transmission. Instead of direct electrical connections between sensors and the control unit, the binary codes serve as a passive information carrier that can be read optically, eliminating bulky wiring while maintaining measurement precision.
3Manufacturing precision
If automatic positioning with motors and carriages is used, then positioning precision is improved, but cost and device dimensions increase
Solution Approach 1:
The patent extracts the positioning feedback function from complex motorized systems. By separating the measurement function (binary code reading) from the positioning action (manual bar movement), the invention achieves accurate positioning without requiring expensive and space-consuming motors and carriages.
Solution Approach 2:
The patent replaces motor-driven automatic positioning with a manual positioning system aided by optical feedback. The binary code reading system substitutes for the mechanical complexity of motors and carriages, providing positioning accuracy through information feedback rather than automated mechanical movement.
