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

VSEngineering 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

Engineering Contradiction:
Improvecompatibility with different connection methodsVSAvoidnumber of shield shell types
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If two types of shield shells are prepared for different connection methods, then both connection types can be accommodated, but manufacturing cost increases
