Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a resin layer is applied on a display panel using conventional methods, then the resin layer can be formed, but the outer surface of the resin layer becomes uneven with bumps
Solution Approach 1:
The patent applies preliminary action by performing a precuring process on a portion of the resin layer before final curing. This intermediate curing step stabilizes the resin structure early in the process, preventing subsequent unevenness and bumps during final curing, thereby achieving a flat surface without requiring complex post-processing steps
Solution Approach 2:
The curing process is segmented into multiple stages: an initial precuring step for a portion of the resin layer, followed by a final curing step. This segmentation allows controlled setting of the resin structure, preventing defects while maintaining process simplicity
2Productivity
If the manufacturing process is simplified, then productivity increases, but the risk of resin layer bumps increases
Solution Approach 1:
The precuring step serves as a preliminary action that prevents bump formation before final curing. This intermediate stabilization ensures reliable, even resin layers while maintaining a streamlined two-step process that does not significantly complicate manufacturing or reduce productivity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method simplifies manufacturing processes, reduces the risk of resin layer bumps, and enhances the evenness of the resin layer surface, improving display quality and attachment to the panel without additional processing steps.
Implementation Method 1
changing a pose of the display panel and the base resin layer... moving at least a portion of the base resin layer along a gravity direction
Implementation Method 2
precuring a portion of the base resin layer... entirely curing the base resin layer
