Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a reflective sheet is used to improve light brightness and Mura performance, then optical performance is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent extracts and removes the reflective sheet from the light source apparatus structure. Instead of using a separate reflective sheet component, the invention integrates light reflection functionality directly into the substrate through a reflective layer formed on the substrate surface, thereby simplifying the overall device structure while maintaining light brightness performance.
Solution Approach 2:
The patent merges the reflective function with the substrate by forming a reflective layer on the substrate surface. This combination eliminates the need for a separate reflective sheet component, reducing device complexity while maintaining the light reflection necessary for brightness and Mura performance.
2Manufacturing precision
If a reflective sheet is attached manually to ensure proper positioning, then positioning accuracy is improved, but productivity decreases
Solution Approach 1:
The patent removes the reflective sheet component entirely and replaces it with a reflective layer formed directly on the substrate. This eliminates the manual attachment process completely, allowing positioning accuracy to be achieved through precise layer formation during manufacturing while dramatically improving productivity.
Solution Approach 2:
The reflective layer is formed on the substrate surface during the manufacturing process before final assembly. This preliminary formation of the reflective layer ensures precise positioning is achieved during fabrication rather than requiring manual alignment and attachment later, thereby improving both precision and productivity.
3Illumination intensity
If a reflective sheet is used to achieve light reflection, then optical performance is improved, but material costs and production time increase
Solution Approach 1:
The patent extracts the reflective sheet component and replaces it with a reflective layer formed on the substrate. This integration reduces material costs by eliminating the separate reflective sheet material and reduces production time by removing the attachment process, while maintaining light brightness through the reflective layer.
Solution Approach 2:
By merging the reflective function into the substrate through a reflective layer, the patent reduces the total material count and simplifies the manufacturing process. This combination maintains optical performance while improving productivity by eliminating separate material procurement and attachment steps.
4Ease of operation
If a reflective sheet is detached from the base film, then repositioning is possible, but static electricity damage occurs
Solution Approach 1:
The patent removes the reflective sheet and its adhesive base film structure. Instead, the reflective layer is formed directly on the substrate through manufacturing processes, eliminating the need for detachment and repositioning operations that generate static electricity, thereby protecting against static electricity damage while maintaining operational flexibility through precise initial positioning.
