Solution Overview

Problem

Existing cabling networks require numerous manual operations, often in confined spaces, and are not waterproof, making them costly and complicated to install, especially when connecting multiple electrical equipment to a main cable without cutting the main conductor.

Innovation Solution

A connector design with a central section that allows for sliding electrical connection means, featuring elongated or nipple-shaped contact sections and a clip for holding the connection, enabling secure connection of secondary conductors to a main conductor without cutting the main cable, while maintaining electrical insulation and allowing detachment of branch cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If terminal blocks are used to connect electrical cables, then electrical connection is achieved, but numerous manual operations are required and the installation becomes complicated

Engineering Contradiction:
Improveease of installationVSAvoidinstallation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connector is divided into a first part that connects to the main cable and a second part that connects to the branch cable, allowing independent assembly and simplifying installation operations

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector components are pre-assembled with the main cable during manufacturing, so that during installation only the branch cable connection is required, reducing manual operations on-site

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If male-female connectors are used to form branches from main cable, then branching connection is achieved, but the main cable must be cut and crimping operations are required

Engineering Contradiction:
Improvebranching capabilityVSAvoidinstallation ease
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The first part of the connector is pre-assembled with the main cable during harness manufacturing, eliminating the need for on-site cutting and crimping operations

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The connector integrates the connection functions for both the main cable and branch cable into a single component, eliminating the need for separate male and female connectors

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If prefabricated harness with overmolded joints is used, then electrical connection is achieved, but prior knowledge of exact cable paths is required and secondary cables hinder harness pulling

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The connector separates the electrical connection function (overmolded joint) from the mechanical attachment function, allowing the harness to be pulled independently without being hindered by branch cable attachments

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector acts as an intermediary component that provides structured attachment points for branch cables without interfering with the main harness pulling operation

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If connectors are used to connect secondary conductors to main conductor, then electrical connection is achieved, but the connection is not waterproof

Engineering Contradiction:
Improveconnection easeVSAvoidwaterproofing
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The connector integrates the electrical connection function with the waterproof sealing function into a single component, eliminating the need for separate sealing elements

Inventive Principle:
Principle #5Merging (Combining)
