Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional bushing housings require significant space due to angled cable routing and are not flexible enough to accommodate varying numbers of cables or types of lines, limiting their use across different functional groups or apparatuses.

Innovation Solution

A space-saving bushing housing design featuring a housing body and removable cover with perpendicular cutout and exit openings, allowing for flexible routing of lines or cables, enhanced shielding with a metal construction and paint coating, and integration with modular plug connectors for secure and versatile connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cables are routed at angles greater than 90 degrees as in conventional bushing housings, then cable routing is achieved, but space consumption increases and flexibility is reduced

Engineering Contradiction:

Improveflexibility for different cable configurationsVSAvoidspace consumption

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent transitions from planar cable routing to three-dimensional routing by positioning the cutout opening and exit openings in perpendicular planes. This dimensional change allows cables to route efficiently through space without requiring large angular clearances, resolving the contradiction between space consumption and routing flexibility

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The bushing housing is designed with a standardized perpendicular geometry that can accommodate varying numbers and types of cables through its multiple exit openings. This universal design allows the same housing structure to serve different functional groups and apparatuses, improving adaptability without increasing space requirements

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If dedicated clearances are provided for each cable, then cable routing is secured, but the number of cables must be predetermined and flexibility is lost

Engineering Contradiction:

Improveadaptability to different functional groupsVSAvoidcable routing configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The housing is divided into multiple independent exit openings that can be selectively used based on the specific application requirements. This segmentation allows the system to accommodate different numbers and types of cables without requiring a complete redesign, reducing device complexity while maintaining adaptability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The standardized perpendicular geometry with multiple exit openings creates a universal interface that can serve different functional groups and apparatuses. This design eliminates the need for predetermined cable configurations while simplifying the overall routing structure

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A bushing housing (1) for leading one or more lines and/or cables out of or into a closed area comprises a housing member (2) and a matching removable housing cover (3). The housing member (2) has a breakthrough hole (5) and at least one exit hole (6, 6′), the planes of which extend substantially perpendicularly to each other.
