Perpendicular Adaptor for Flexible Flat Cable Height Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible flat cables in electronic products often require bending to connect with printed circuit boards, leading to increased height and length requirements due to the need for space and height to accommodate the bend, which is inefficient.
Innovation Solution
An adaptor design featuring a substrate and housing structure where the substrate is inserted perpendicularly to the flat cable's path, allowing direct connection to terminal holes without bending, thus reducing the overall height and length of the flexible flat cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flexible flat cable is bent to connect with the printed circuit board, then the connection is achieved, but the height and length of the product increase
Solution Approach 1:
The patent changes the connection dimension from a bent cable path (requiring vertical space) to a perpendicular insertion direction. The substrate is inserted into the housing in a direction perpendicular to the flat cable's passing direction, enabling direct connection to terminal holes without bending, thus reducing the height requirement of the product.

3Length of stationary object
If the substrate is inserted perpendicularly to the flat cable path, then the height and cable length are reduced, but the housing structure becomes more complex
Solution Approach 1:
The housing is segmented into functional components: a first housing for receiving the substrate and providing the first insertion hole, and a second housing for receiving the flat cable and providing the second insertion hole. This segmentation allows the complex perpendicular insertion function to be achieved through modular design, where each housing component has a specific function.
Solution Approach 2:
The second housing is disposed inside the first housing, creating a nested structure. This nesting arrangement allows the complex perpendicular insertion function to be achieved within a compact form factor, reducing the overall product height while maintaining the functional complexity through spatial arrangement rather than structural complexity.

AI summary
An adaptor includes a substrate, a first housing, and a flat cable. The substrate comprises a terminal hole. The first housing includes a first insertion hole and a second insertion hole. The substrate is inserted into the first insertion hole. The flat cable includes a plurality of conductors. Each of the conductors includes a conductor terminal. The flat cable passes through the second insertion hole. The conductor terminal is connected to the terminal hole. A direction in which the substrate is inserted into the first insertion hole is perpendicular to a direction in which the flat cable passes through the second insertion hole.
