Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If carriers are moved during inspection, then inspection coverage is improved, but inspection reliability deteriorates due to vibration-induced errors
Solution Approach 1:
The inspection base is divided into multiple inspection areas (first inspection area, second inspection area, third inspection area) with distinct coil sets. Carriers are segmented into different groups (first carriers, second carriers) that can be independently positioned and inspected in separate zones, allowing simultaneous inspections without interference or vibration between areas.
Solution Approach 2:
Coils act as intermediaries to enable precise positioning and movement control of carriers. By using electromagnetic fields from coils, the system can move carriers to specific inspection areas and hold them stationary during inspection, eliminating mechanical vibration while maintaining inspection coverage.
2Reliability
If multiple inspections are performed sequentially, then inspection thoroughness is improved, but inspection time increases
Solution Approach 1:
The system enables continuous inspection operations by having multiple inspection areas operating simultaneously. While first carriers are inspected in the first inspection area, second carriers can be moved to or inspected in the second inspection area without interruption, maintaining continuous productive action throughout the inspection process.
Solution Approach 2:
Carriers are pre-positioned in specific inspection areas using coils before inspection begins. The system prepares multiple carriers in advance at different inspection stations, so that when one inspection completes, another carrier is already ready for immediate inspection, eliminating waiting time and maintaining continuous operation.
3Adaptability or versatility
If carriers are repositioned between inspections, then inspection flexibility is improved, but system complexity increases
Solution Approach 1:
The coils serve multiple functions: they position carriers, move carriers between inspection areas, and hold carriers stationary during inspection. This multi-functional use of a single component type simplifies the overall system architecture while maintaining high flexibility for various inspection configurations and sequences.
