Integrated Printed Circuit Board Design for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of slide-type cellular phones is hindered by the need for separate and subsequently connected main and auxiliary printed circuit boards, increasing component count, manufacturing costs, and assembly time due to the requirement for connectors and additional flexible printed circuit boards.
Innovation Solution
A display device with a printed circuit board featuring a main board portion, a connection board portion, and an auxiliary board portion integrally formed, where the connection board portion connects the main and auxiliary boards, reducing the need for separate connectors and flexible printed circuit boards by forming a continuous unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the main board portion and auxiliary board portion are manufactured as separate printed circuit boards, then the device can be assembled with modular components, but the number of components, manufacturing costs, and assembly time increase
Solution Approach 1:
The patent merges the main board portion and auxiliary board portion into a single integrated printed circuit board structure. The connection board portion extends from the main board and integrates the auxiliary board functions, eliminating the need for separate connectors and flexible printed circuit boards. This merging reduces the total number of components while maintaining modular functionality through the continuous printed circuit board design.
2Reliability
If separate connectors and flexible printed circuit boards are used to connect the main board portion and auxiliary board portion, then the boards can be connected, but the manufacturing costs and assembly time further increase
Solution Approach 1:
The connection board portion is integrated directly into the printed circuit board structure, merging the connection function with the board itself. This eliminates the need for separate connectors and flexible printed circuit boards, reducing assembly steps and time while maintaining reliable electrical connections through the continuous circuit board design.
3Adaptability or versatility
If the main board portion and auxiliary board portion are manufactured separately, then each board can be optimized independently, but the overall manufacturing cost increases
Solution Approach 1:
The integrated printed circuit board is segmented into distinct functional portions: the main board portion, the connection board portion, and the auxiliary board portion. Each portion can be independently optimized for its specific function while being manufactured as a single integrated structure, reducing overall manufacturing cost by eliminating the need for separate manufacturing processes and assembly operations.
