Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional mechanical transport and support methods are used for large-size display screen substrates, then the substrates can be transported between production apparatuses, but the substrates are severely deformed and damaged due to uneven support
Solution Approach 1:
The support structure is divided into multiple support bars arranged in arrays, where each bar provides localized support. This segmentation allows the support system to adapt to different substrate sizes and shapes while distributing the load uniformly across the entire substrate surface, preventing deformation and damage during transportation.
Solution Approach 2:
The support bars are configured to be movable along the support plate, allowing dynamic adjustment of the support configuration. This enables the system to adapt to different substrate dimensions and transport requirements, providing optimal support distribution for each specific case and preventing damage.
2Reliability
If manual foam box methods are used for large-size display screens, then substrate damage is reduced, but huge manpower loss occurs and production efficiency deteriorates
Solution Approach 1:
The support system is designed to automatically adjust and position the support bars without manual intervention. The movable support bars self-adjust to provide optimal support configuration, eliminating the need for manual foam box placement while maintaining substrate protection, thus improving production efficiency.
Solution Approach 2:
The manual mechanical operation of placing foam boxes is replaced with an automated support system featuring movable support bars. This substitution eliminates manual labor while providing consistent, reliable substrate support and protection throughout the transportation process.
3Reliability
If uniform and stable support is provided for display screen substrates, then substrate deformation and damage are prevented, but device complexity increases due to the support assembly structure
Solution Approach 1:
The support assembly with movable support bars serves multiple functions: it provides uniform support distribution, prevents substrate deformation, accommodates different substrate sizes, and enables automated operation. This multi-functionality achieves reliable substrate protection without proportionally increasing device complexity.
Solution Approach 2:
The support system utilizes adjustable parameters such as the position and spacing of support bars to achieve optimal support configuration. By changing these parameters rather than redesigning the entire structure, the system maintains substrate stability while keeping the device complexity manageable.
