Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sealant process design is customized for each size and specification of switchable glass, then the switchable glass can meet specific application requirements, but the debugging time and equipment occupancy increase significantly
Solution Approach 1:
The sealant process is segmented into modular components: a first sealant forming a first grid pattern, a second sealant forming a second grid pattern, and an edge sealant. These modular sealant structures can be independently configured and combined to accommodate different glass sizes and specifications without requiring complete process redesign, thereby reducing debugging time while maintaining adaptability.
Solution Approach 2:
The patent creates a universal sealant process design that can serve multiple glass sizes and specifications simultaneously. By using standardized grid patterns formed by first and second sealants that can be scaled and configured differently, the same basic process framework can produce various switchable glass products, eliminating the need for separate debugging for each specification.
2Adaptability or versatility
If sealant process design is customized for each size and specification of switchable glass, then the switchable glass can meet specific application requirements, but the equipment occupancy and worker demands increase
Solution Approach 1:
The sealant application process is divided into distinct segmentation steps: applying first sealant to form first grids, applying second sealant to form second grids, and applying edge sealant. This segmentation allows each step to be performed with standardized equipment and procedures that can be reused across different glass specifications, reducing the need for specialized equipment configurations and lowering overall equipment complexity.
Solution Approach 2:
The patent introduces dynamic flexibility into the sealant process by allowing the grid patterns and sealant quantities to be adjusted based on the desired glass specification. This dynamic approach enables the same equipment to handle various sizes and specifications by simply modifying process parameters rather than requiring dedicated equipment for each product type, thereby reducing equipment occupancy requirements.
3Productivity
If traditional sealant process is used for producing various sizes of switchable glass, then production can be carried out, but the production efficiency is low
Solution Approach 1:
The patent implements preliminary action by pre-establishing standardized sealant grid patterns and application procedures that can be directly applied to different glass specifications. Instead of designing sealant processes from scratch for each product, the pre-defined first and second sealant grids provide a ready-to-use framework that accelerates production while maintaining ease of manufacture through standardized procedures.
Solution Approach 2:
The patent leverages parameter changes to improve production efficiency. By varying parameters such as sealant quantity, grid spacing, and pattern configuration within the standardized process framework, the same manufacturing procedure can produce different glass specifications efficiently. This approach maintains ease of manufacture through parameter adjustment rather than process redesign, thereby significantly improving productivity.
