Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional window glass manufacturing methods are used, then the manufacturing process is simple, but the surface characteristics are poor and do not support folding or bending operations
Solution Approach 1:
The base jig is divided into multiple sub-jigs that can be independently positioned and adjusted. Each sub-jig can be selectively placed in the groove area to create different slimming region shapes, allowing precise control of the etching process while maintaining a relatively simple overall device structure.
Solution Approach 2:
The nozzle portion is designed to be movable in at least one moving direction parallel to the first direction. This dynamic positioning capability allows the nozzle to adapt to different groove area shapes and provide etching solution uniformly across various slimming region configurations, improving surface characteristics without requiring a completely complex fixed system.
2Adaptability or versatility
If the groove area shape is fixed, then the manufacturing process is simple, but the ability to control the slimming region shape is limited
Solution Approach 1:
The base jig is divided into multiple sub-jigs that can be independently positioned and adjusted. Each sub-jig can be selectively placed in the groove area to create different slimming region shapes, allowing precise control of the etching process while maintaining a relatively simple overall device structure.
Solution Approach 2:
The base jig with multiple sub-jigs can accommodate various groove area shapes and slimming region configurations through selective assembly of sub-jigs. This multi-functional capability allows a single base jig design to serve multiple manufacturing purposes, improving adaptability without proportionally increasing device complexity.
3Manufacturing precision
If the nozzle portion is fixed, then the device structure is simple, but the uniformity of etching across different positions cannot be ensured
Solution Approach 1:
The nozzle portion is designed to be movable in at least one moving direction parallel to the first direction. This dynamic positioning capability allows the nozzle to adapt to different groove area shapes and provide etching solution uniformly across various slimming region configurations, improving surface characteristics without requiring a completely complex fixed system.
Solution Approach 2:
The nozzle portion can be positioned at different locations and orientations relative to the groove area, allowing localized adjustment of etching solution delivery. This enables optimized etching uniformity for specific regions of the base glass, addressing local quality requirements without requiring the entire nozzle system to be overly complex.
4Manufacturing precision
If the etching solution is applied without controlled movement, then the manufacturing process is simple, but the surface quality and folding characteristics are compromised
Solution Approach 1:
The nozzle portion is designed to be movable in at least one moving direction parallel to the first direction. This dynamic positioning capability allows the nozzle to adapt to different groove area shapes and provide etching solution uniformly across various slimming region configurations, improving surface characteristics without requiring a completely complex fixed system.
Solution Approach 2:
The movable nozzle portion enables continuous and uniform application of etching solution across the groove area by maintaining optimal positioning throughout the etching process. This continuous adjustment ensures consistent surface quality and folding characteristics while keeping the manufacturing process efficient through automated movement control.

AI summary
A window glass manufacturing device includes a base jig including a groove area concavely recessed with respect to flat surfaces and a nozzle portion disposed above the base jig so as to correspond to the groove area and controlled to move in at least one of the upward/downward direction or the left/right direction which is parallel to the first direction, thereby having excellent surface quality.
