Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The separate soldering of cable shields to electronic assemblies is time-consuming and prone to errors, especially when connecting multiple cables with cable shields to various electronic assemblies.
Innovation Solution
A crimp connector with a hollow cylindrical inner sleeve and outer sleeve, where the cable screen is arranged in the radial freedom between the sleeves and fixed by plastic deformation, allowing for easy, reliable, and quick connection of cables, including cable shields, to electronic assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable shields are soldered separately to electronic assemblies, then electrical connection is achieved, but the process becomes time-consuming and error-prone
Solution Approach 1:
The patent combines the cable shield connection and the connector attachment into a single integrated operation. The cable shield is clamped between the inner and outer sleeves of the crimp connector, allowing both the shield and the connector to be attached to the cable simultaneously through one crimping action, eliminating the need for separate soldering steps
Solution Approach 2:
The cable shield is pre-positioned between the inner and outer sleeves during cable assembly, before the final connection to the electronic assembly. This preliminary positioning ensures proper alignment and eliminates the need for complex mechanical adjustments later during the connection process
2Ease of manufacture
If cable shields are soldered individually on electronic assemblies, then electrical connection is established, but manufacturing complexity increases
Solution Approach 1:
The connector is divided into an inner sleeve and an outer sleeve that work together to clamp the cable shield. This segmentation allows the shield to be securely held between the two sleeves, simplifying the overall attachment process while maintaining connection reliability
Solution Approach 2:
The inner and outer sleeves act as intermediary elements that facilitate the connection between the cable shield and the electronic assembly. These sleeves provide a mechanical interface that simplifies the connection process compared to direct soldering

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The crimp connector enables pre-assembly of cables with connectors, simplifies cable shielding, and ensures high process reliability with symmetric cable tensile load relief, reducing manual errors and increasing efficiency.
Implementation Method 1
The outer sleeve and the inner sleeve are designed to be fixed together by plastic deformation, at least of the outer sleeve, in particular by crimping or, more generally, by squeezing
