Solution Overview

Problem

Existing connector housings face challenges in simplifying cable gland assembly while preventing contamination and requiring additional tools for opening cable exits, leading to inefficiencies in installation time and potential damage to cables.

Innovation Solution

A connector housing design with pre-wired cable exits featuring internal threads and integral locking mechanisms that allow cable glands to be screwed in, breaking open the closure through a predetermined weak point without tools, ensuring a sealed and tool-free installation process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a cover is used to close the cable exit, then contamination is prevented, but tool-free installation is lost and installation time increases

Engineering Contradiction:
ImprovecontaminationVSAvoidinstallation ease
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The cable exit closure is segmented into a main housing and a separate breakable cap. The cap can be easily removed by hand to allow cable gland installation, while the main housing remains sealed. This segmentation enables both contamination protection during storage/transport and tool-free installation during assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cable exit is pre-prepared with an internal thread and a breakable cap that is easily removable by hand. This preliminary preparation eliminates the need for tools during installation while maintaining contamination protection before installation occurs.

Inventive Principle:
Principle #10Preliminary action

2Object-affected harmful factors

If the cable exit is permanently sealed, then contamination is prevented, but cable gland installation requires additional tools and time

Engineering Contradiction:
ImprovecontaminationVSAvoidinstallation time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The closure is divided into a permanent sealed housing and a removable breakable cap. The cap is designed to be easily removed by hand, eliminating the need for drilling or special tools, while the housing maintains its sealed structure for contamination protection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The breakable cap is designed as a disposable or single-use component that is easily removed during installation. Its simple structure and easy removability compensate for the permanent sealed housing, enabling fast installation without tools.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If the cable exit is open, then cable gland installation is simplified, but dirt can enter and impair cable function

Engineering Contradiction:
Improveinstallation easeVSAvoidcontamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cable exit structure is segmented into an openable cap and a sealed housing. The cap can be easily removed to allow cable gland installation, while the housing maintains its sealed structure to prevent contamination during storage and transport.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cable exit is pre-prepared with an internal thread and a breakable cap that is easily removable by hand. This preliminary preparation enables both contamination protection during storage/transport and tool-free installation during assembly.

Inventive Principle:
