Universal Shield Shell Integrating Collective and Individual-Core Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The need for two types of shield shells, collective and individual-core, to accommodate different connection methods in devices limits the versatility and increases the complexity and cost of shield connectors.
Innovation Solution
A common shield shell system that integrates both collective and individual-core shield connecting portions, formed from a metal plate and connected using caulking rings, allowing for a single shield shell to handle both types of connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two types of shield shells (collective and individual-core) are prepared to accommodate different connection methods, then both connection types can be supported, but the number of components increases and manufacturing complexity increases
Solution Approach 1:
The shield shell is designed with a universal structure that includes both a collective shield connecting portion and multiple individual-core shield connecting portions. This allows a single shield shell type to accommodate both collective shield type connections (where a single braided wire covers multiple wires) and individual-core shield type connections (where separate braided wires cover individual wires), thereby supporting multiple connection methods without requiring multiple shield shell variants.
Solution Approach 2:
The invention merges the functions of two previously separate shield shell types into a single unified shield shell structure. By integrating both collective and individual-core connecting portions into one shield shell, the design eliminates the need to maintain separate inventory of different shield shell types while preserving compatibility with both connection methodologies.

3Reliability
If separate shield shells are used for collective and individual-core types, then each connection type can be optimized, but the connection process becomes more complex
Solution Approach 1:
The shield shell is designed with a universal structure that includes both a collective shield connecting portion and multiple individual-core shield connecting portions. This allows a single shield shell type to accommodate both collective shield type connections (where a single braided wire covers multiple wires) and individual-core shield type connections (where separate braided wires cover individual wires), thereby supporting multiple connection methods without requiring multiple shield shell variants.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a reduction in component count and mold costs, simplifies the connection process, and eliminates the need for separate sections to adjust wire intervals, while maintaining effective shielding for both connection types.
Implementation Method 1
The shell main body, the collective shield connecting portion and the plurality of individual-core shield connecting portions can be formed by drawing a metal plate material.
Implementation Method 2
the shielding member(s) can be connected to the collective shield connecting portion or the plurality of individual-core shield connecting portions by the caulking ring(s)
