Extensible FPC for LCD Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing flexible printed circuit boards (FPCs) for LCD modules require multiple designs and shapes to accommodate different LCD modules, leading to increased complexity and resource wastage due to varying pad positions on the PCB, necessitating a solution that allows a single FPC to be adaptable to various modules.
Innovation Solution
Incorporating an extensible element into the FPC that can extend to a predetermined length when a force is applied, allowing the same FPC to be used across different LCD modules by modifying its length either longitudinally or laterally, manufactured in a single process using materials like Polymer or Polyester, with shapes such as embossing, saw-tooth, or arc.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple FPC designs are used to accommodate different LCD modules, then adaptability to various modules is improved, but device complexity and material preparation complexity increase
Solution Approach 1:
The patent applies universality by designing a single standardized FPC shape that can be used across different LCD modules. The FPC includes an extensible element that allows the same basic design to accommodate various module sizes and pad positions, eliminating the need for multiple specialized FPC designs while maintaining adaptability.
Solution Approach 2:
The patent applies dynamics by incorporating an extensible element into the FPC that can be extended or compressed to adjust the effective length of the FPC. This dynamic feature allows a single FPC design to adapt to different module configurations without requiring multiple static designs, thereby reducing complexity while maintaining versatility.
2Adaptability or versatility
If multiple FPC shapes are designed for different pad positions, then adaptability is improved, but loss of substance and resource wastage increase
Solution Approach 1:
The patent eliminates resource wastage by creating a universal FPC design that can serve multiple pad position configurations. The extensible element allows the same FPC to be adapted to different module types, meaning only one FPC shape needs to be manufactured in quantity, preventing the material wastage associated with producing multiple specialized shapes that may not all be used.
Solution Approach 2:
The patent applies parameter changes by modifying the physical state of the FPC through the extensible element, which can be extended or compressed to achieve different effective lengths. This allows a single FPC design with fixed material dimensions to adapt to various module requirements, eliminating the need to manufacture different material quantities for different shapes.
3Adaptability or versatility
If FPC shape is redesigned for different module requirements, then adaptability is improved, but loss of time and manufacturing efficiency decrease
Solution Approach 1:
The patent eliminates redesign time by establishing a universal FPC template that works across different module configurations. The extensible element provides the necessary adaptability without requiring redesign, allowing manufacturers to simply extend or compress the same basic design rather than creating new shapes for each module type.
Solution Approach 2:
The patent applies dynamics by using the extensible element to provide adaptability through physical extension or compression rather than through redesign. This dynamic adjustment mechanism allows the same FPC design to serve multiple purposes without requiring time-consuming redesign processes for different module configurations.
4Ease of operation
If connector is used to connect FPCs, then ease of assembly is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent applies merging by integrating the connection function directly into the FPC structure through the extensible element, which can be extended to reach and connect with the PCB pad. This eliminates the need for separate connectors, thereby reducing device complexity while maintaining ease of assembly through the simplified direct connection approach.
