Solution Overview

Problem

Existing rubber plugs and Glan headers are limited in their ability to accommodate cables of different types and diameters while ensuring waterproof sealing, and they are not suitable for the special wire head structure of network cables, leading to high costs and space occupancy.

Innovation Solution

A threading assembly with a replaceable portion that includes a first threading part and a second threading part, allowing cables of different diameters or types to be installed by utilizing a gap in the axial direction of the second threading hole, which reduces installation difficulty and ensures sealing performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rubber plug or Glan header is used for waterproof protection, then sealing performance is improved, but adaptability to different cable types and diameters deteriorates

Engineering Contradiction:
Improvesealing performanceVSAvoidadaptability to different cable types and diameters
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The threading assembly is divided into a base portion and a replaceable portion that can be detached and replaced. The replaceable portion includes different threading parts (first threading part, second threading part) that can be exchanged based on cable requirements, allowing the system to maintain good sealing performance for each cable type while adapting to different cable diameters and types.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The threading assembly is designed to accommodate multiple cable types and diameters through its modular structure. The base portion provides a universal mounting interface, while the replaceable portion can be configured with different threading parts to suit different cable requirements, making the assembly universally applicable to various cable scenarios.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If a Grand head is used to install network cables, then waterproof requirement is met, but device complexity and space occupancy increase

Engineering Contradiction:
Improvewaterproof requirementVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The threading assembly separates the waterproof sealing function (base portion with sealing portion) from the cable installation function (replaceable portion with threading parts). This segmentation allows the use of a simpler structure compared to the complex Grand head, while still meeting waterproof requirements through the sealing portion's interaction with cables.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The replaceable portion can be easily replaced or modified depending on cable requirements, unlike the fixed and complex Grand head structure. This approach uses simpler, more economical components that can be swapped out as needed, reducing overall device complexity and cost.

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

3Ease of manufacture

If a fixed threading structure is used, then manufacturing simplicity is improved, but adaptability to different cable diameters deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidadaptability to different cable diameters
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The threading assembly is segmented into a base portion (easy to manufacture with standard sealing structures) and a replaceable portion (can be manufactured in different configurations for different cable diameters). This segmentation maintains manufacturing simplicity for the base while allowing customization of the replaceable parts for different cable sizes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The threading assembly transitions from a fixed structure to a dynamic, reconfigurable structure. The replaceable portion can be changed to match different cable diameters, providing adaptability while keeping the base portion's manufacturing simple and standardized.

Inventive Principle:
Principle #15Dynamics
