Solution Overview

Problem

Existing connection devices for computer applications face challenges in achieving a balance between robustness, structural simplicity, compactness, and ease of use, as they need to connect plugs from multiconductor cables in opposite directions while ensuring galvanic continuity and meeting specific standards like IEC 61076.

Innovation Solution

A connection device with bayonet-folded multiconductor sheet internal link providing galvanic continuity between sockets, featuring rigid end portions connected to pins and a flexible intermediate portion, housed in two identical shells with male and female fastening members, and optional metal grounding screens for enhanced connectivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional rigid multiconductor connections are used, then galvanic continuity is ensured, but the device complexity and difficulty of assembly increase

Engineering Contradiction:
Improvegalvanic continuityVSAvoidconnection structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the intermediate portion of the multiconductor connection flexible rather than rigid. This allows the connection to adapt to assembly variations and maintain galvanic continuity without requiring complex alignment mechanisms, thus reducing device complexity while ensuring reliable electrical contact between sockets.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the physical state parameter of the multiconductor connection by transitioning from a completely rigid structure to a hybrid structure with flexible intermediate portions. This parameter change enables the connection to accommodate manufacturing tolerances and assembly variations, maintaining galvanic continuity while simplifying the overall connection structure.

Inventive Principle:
Principle #35Parameter changes

2Ease of manufacture

If the housing is formed as a single piece, then structural simplicity is achieved, but manufacturing precision and assembly flexibility decrease

Engineering Contradiction:
Improvehousing constructionVSAvoidsocket positioning
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent applies segmentation by dividing the housing into multiple separate components rather than forming it as a single piece. This allows each component to be manufactured independently with standard tolerances, then assembled together to achieve the required precision for socket positioning, thereby improving both ease of manufacture and manufacturing precision.

Inventive Principle:
Principle #1Segmentation

3Volume of moving object

If the connection device is made compact, then space efficiency is improved, but ease of operation and cable access are reduced

Engineering Contradiction:
Improvedevice sizeVSAvoidplug insertion
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent applies dimensionality change by arranging the sockets and cables in a three-dimensional configuration rather than a flat two-dimensional layout. This allows the device to maintain a compact footprint while providing adequate space for cable access and plug insertion through vertical or depth-based separation of connection points.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
