Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a pattern glass with groove patterns is used in foldable display devices, then the visibility is improved, but the manufacturing complexity increases
Solution Approach 1:
The pattern glass is divided into multiple groove patterns (first groove patterns on the upper surface and second groove patterns on the lower surface), with each groove pattern filled by corresponding resin layers. This segmentation allows the complex patterned glass to be manufactured through modular processes, reducing overall manufacturing complexity while maintaining the visibility-enhancing patterned structure.
Solution Approach 2:
The groove patterns are formed on the glass substrate before the resin filling process. By preparing the groove structures in advance on the glass, the subsequent resin filling becomes a simpler, more straightforward process, thereby reducing the overall manufacturing complexity while achieving the desired visible patterned effect.
2Productivity
If resin layers are added to fill groove patterns, then the manufacturing efficiency is improved, but the device complexity increases
Solution Approach 1:
The first resin layer and second resin layer are combined to completely fill both the first groove patterns and second groove patterns of the pattern glass. This merging of multiple resin filling operations into a coordinated process improves manufacturing efficiency by reducing the number of separate steps, while the layered structure manages the complexity through systematic organization.
Solution Approach 2:
The resin materials are selected with specific parameters (first resin material and second resin material with potentially different properties) to optimize the filling process and final product performance. By carefully selecting and adjusting resin parameters such as viscosity, curing characteristics, and optical properties, the manufacturing process becomes more efficient while the structural complexity is managed through material optimization.
3Illumination intensity
If a flat portion is added to the resin layer, then the visibility is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The resin layer is segmented into multiple functional portions: a first flat portion filling the first groove patterns, a second flat portion filling the second groove patterns, and potentially intermediate transition portions. This segmentation allows each portion to be optimized and controlled independently, reducing the overall manufacturing precision requirements compared to forming a single complex flat surface.
Solution Approach 2:
The groove patterns are formed on the glass substrate before resin filling, creating predetermined geometric constraints that guide the resin flow and final flat portion formation. By preparing the groove structures in advance with precise dimensions, the subsequent resin filling process achieves the desired flat portions with reduced precision requirements, as the groove geometry itself defines the final flat surface boundaries.
