Integrated FPC-to-PCB Connector Cap for Low-Height Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical wiring solutions for flexible printed circuits (FPCs) in limited spaces, such as aircraft interiors, are complex, time-consuming, and require multiple connector parts, which are cumbersome and inefficient.
Innovation Solution
A connection interface with a single connector cap featuring first and second contact areas arranged next to each other, allowing direct FPC to PCB connection without duplication, reducing the number of loose elements and overall height, and enabling automatic production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a two-part connector solution with separate male and female connectors is used, then reliable electrical connection is achieved, but device complexity and number of parts increase
Solution Approach 1:
The patent combines the male and female connector parts into a single integrated connector cap that contains both contact areas (first contact area for FPC connection and second contact area for PCB connection). This merging eliminates the need for separate connector components while maintaining reliable electrical connection functionality.
Solution Approach 2:
The connector cap serves multiple functions simultaneously: it provides both male and female connection interfaces, houses the electrical contacts, provides structural support, and enables direct signal transmission between FPC and PCB through its integrated design.
2Reliability
If traditional pin connections with multiple connector parts are used, then electrical wiring requirements are met, but weight increases
Solution Approach 1:
By merging multiple connector parts into a single integrated connector cap, the total material用量 is reduced, directly decreasing the weight of the wiring connection assembly while maintaining all necessary electrical connection capabilities.
3Reliability
If separate male and female connectors are used, then adequate contact areas are provided, but overall height and assembly space increase
Solution Approach 1:
The patent arranges the first and second contact areas in neighboring regions on the same connector cap, utilizing lateral spatial arrangement rather than vertical stacking. This dimensional reorganization reduces the overall height requirement while providing sufficient contact areas for both FPC and PCB connections.
4Adaptability or versatility
If multiple loose connector elements are used, then connection flexibility is achieved, but ease of operation and assembly deteriorate
Solution Approach 1:
The integration of all connector elements into a single connector cap eliminates the need for assembling multiple loose parts, significantly improving ease of operation and assembly while maintaining connection flexibility through the cap's design that accommodates both FPC and PCB interfaces.
