Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing process of liquid crystal display devices is complicated and costly due to the need for redesigning and reproducing the case top when design changes are required, as the supporters are integrated with it, necessitating new dies and processes.
Innovation Solution
A liquid crystal display device with a case top that includes a separately manufactured supporter made of conductive material, adhered using double-sided tape or conductive adhesive, which is electrically connected to the printed circuit board, allowing for design flexibility without requiring a new case top, thus simplifying the manufacturing process and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If supporters are integrated with the case top, then structural stability is improved, but manufacturing complexity and cost increase when design changes are required
Solution Approach 1:
The supporter is separated from the case top into an independent component. The case top and supporter are manufactured separately and then assembled together through adhesive bonding, allowing the supporter to be replaced or modified without redesigning the entire case top structure.
Solution Approach 2:
The supporter function is extracted from the integrated case top structure and implemented as a separate adhered component. This extraction enables independent manufacturing and modification of the supporter while maintaining its structural support function.
2Strength
If supporters are integrated with the case top, then structural integrity is improved, but production cost increases due to redesign requirements
Solution Approach 1:
By segmenting the case top and supporter into separate components, design changes can be made to the supporter without requiring costly redesign and reproduction of the entire case top, significantly reducing production costs for design iterations.
Solution Approach 2:
The supporter is designed as a separate, replaceable component that can be easily manufactured and replaced if design changes are needed, avoiding the high cost of reproducing the entire integrated case top structure.
3Ease of operation
If supporters are integrated with the case top, then assembly simplicity is improved, but design flexibility deteriorates
Solution Approach 1:
The case top and supporter are segmented into separate components that are assembled through adhesive bonding. This segmentation maintains assembly simplicity while enabling independent modification of the supporter for design changes.
Solution Approach 2:
The supporter is designed as a separate, dynamically replaceable component rather than a fixed integrated part, allowing the design to adapt to different requirements without complicating the assembly process.
