Solution Overview

Problem

The aesthetic issue of protruding electrical cables between electronic equipment in homes, due to the inability to achieve exact cable lengths, is exacerbated by positional offsets causing tension on connection ports.

Innovation Solution

An electrical connection member with flexible conductors and a sheath design that allows for excess length and flexibility in three directions and rotations, preventing tension on connections and enabling adaptation to equipment offsets, while being pressed against the equipment for concealment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rigid electrical cables of fixed length are used to connect electronic equipment, then the connection is stable and reliable, but the cables protrude laterally and alter the aesthetics when equipment positioning varies

Engineering Contradiction:
Improveconnection stabilityVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The patent applies this principle by using a flexible sheath (gaine flexible) that can bend and deform to accommodate equipment positioning variations. The sheath contains the cables and allows them to flex without exposing them laterally, maintaining aesthetics while preserving connection stability through the flexible intermediate section that adapts to positional offsets.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent applies this principle by making the intermediate section of the sheath flexible rather than rigid, allowing the cable assembly to dynamically adapt its shape and length according to the actual positioning of the equipment. This dynamic flexibility resolves the contradiction by enabling the connection to remain stable while the external appearance adapts to aesthetic requirements.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If cables are made longer to accommodate equipment offset, then positional variations can be absorbed, but tension is exerted on the connection ports altering aesthetics and potentially damaging connections

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidtension on connection ports
Core Design Contradiction:
Adaptability or versatilityVSForce

Solution Approach 1:

The flexible sheath absorbs the excess cable length while containing the cables, allowing positioning flexibility without transmitting tension forces to the connection ports. The sheath acts as a flexible buffer that accommodates offset variations aesthetically.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The flexible intermediate section of the sheath acts as an intermediary element between the equipment connection points, absorbing positional variations and preventing direct transmission of tension forces. This mediator allows adaptability while protecting the connection ports from harmful forces.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Shape

If exact cable length is used to match equipment spacing, then aesthetics are improved by minimizing protrusion, but any slight offset causes tension on cables and connection ports

Engineering Contradiction:
Improvecable arrangement aestheticsVSAvoidconnection reliability
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The flexible sheath allows the cable assembly to maintain an aesthetically pleasing compact form while internally accommodating length variations through its flexibility. This resolves the contradiction by decoupling the external aesthetic appearance from the internal cable tension management.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The flexible intermediate section provides beforehand cushioning by absorbing potential tension forces before they can transmit to the connection ports. This preemptive flexibility protection maintains both aesthetics and connection reliability by preventing tension buildup from slight offsets.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

Electrical coupling member, comprising electrical conductors (2) extending in a casing (3) which has end segments (4) that are generally parallelepipedal in cross-section and each have at least one main face (4.2). The conductors have ends coupled to two external connectors (6) which both project from one of the main faces and are both guided out of the casing on the same side of said casing. The casing comprises at least one flexible intermediate segment (5) freely receiving an overlength of the electrical conductors. Set of superposed electronic devices coupled by a coupling member of this type.
