Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If panels are arranged at two sides of liquid crystal module conveying passage for inspection, then inspection can be performed, but the device becomes large in volume and complicated in structure
Solution Approach 1:
The patent combines multiple inspection stations (pre-inspection, inspection, and post-inspection stations) into a single integrated conveying passage. The liquid crystal modules are inspected while being conveyed through the passage, eliminating the need for separate inspection areas and reducing overall device complexity while maintaining comprehensive inspection capability.
Solution Approach 2:
The conveying passage serves multiple functions simultaneously: it transports liquid crystal modules and provides inspection stations at different positions. This multi-functional design reduces the need for separate dedicated inspection equipment, thereby simplifying the overall device structure while ensuring reliable inspection.
2Reliability
If liquid crystal modules are moved out of conveying passage for inspection and then moved back, then inspection is completed, but the process becomes time-consuming
Solution Approach 1:
The patent enables continuous inspection of liquid crystal modules as they are conveyed through the passage. Modules undergo pre-inspection, main inspection, and post-inspection while continuously moving through different stations, eliminating the need to stop and move modules in and out of the conveying system, thus significantly reducing inspection time while ensuring complete inspection.
Solution Approach 2:
Pre-inspection stations are positioned before the main inspection area, allowing initial screening to be performed while modules are being conveyed into the system. This preliminary action identifies modules that need detailed inspection, optimizing the overall inspection process efficiency without compromising completeness.
3Reliability
If separate inspection positions and conveying positions are arranged, then inspection can be performed, but the production cost increases
Solution Approach 1:
The patent merges inspection positions and conveying positions into a single integrated system where the conveying passage also serves as the inspection pathway. This eliminates the need for separate inspection areas and reduces the total number of components required, thereby lowering production costs while maintaining full inspection functionality.
Solution Approach 2:
The conveying passage is designed to serve dual purposes: transportation and inspection. By making the conveying system multi-functional, the patent reduces the need for additional dedicated inspection equipment, lowering overall production costs while ensuring reliable inspection of liquid crystal modules.
4Reliability
If conventional transfer device is designed with separate inspection and conveying areas, then inspection is possible, but it is not apt to be arranged in plant area
Solution Approach 1:
The patent combines inspection areas and conveying areas into a single compact integrated passage, dramatically reducing the overall device footprint. This allows the transfer device to be easily arranged within plant areas while maintaining complete inspection capability through multiple inspection stations positioned along the conveying path.
