Solution Overview

Problem

Existing conduit sealing methods require significant time and material costs due to difficulties in separating wires, often necessitating multiple attempts to achieve a desired sealing effect, and are prone to adhesion issues from temperature effects and lack of visual inspection, requiring multiple workers and complex installation processes.

Innovation Solution

A device that separates cables within a conduit using a cable-separating component with removable portions and a nozzle for precise sealant injection, allowing for quick and reliable sealing without requiring large-scale cable movement, reducing the need for multiple installers and improving adhesion to conduit walls.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional conduit sealing methods are used, then sealing can be achieved, but significant time and material costs are incurred due to difficulties in separating wires and multiple installation attempts

Engineering Contradiction:
Improvesealing reliabilityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The sealing device is divided into distinct functional segments: a body portion with internal cavities for sealant, a nozzle assembly for precise application, and a cable-separating component with notches. This segmentation allows each component to perform its specific function efficiently, enabling reliable sealing without time-consuming wire separation attempts

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cable-separating component with notches is installed beforehand to automatically position and separate cables before sealant application. The notches pre-establish cable positioning, eliminating the need for multiple attempts to achieve proper cable separation and sealing

Inventive Principle:
Principle #10Preliminary action

2Reliability

If traditional sealing methods are used, then sealing can be achieved, but complex installation processes requiring multiple workers are necessary

Engineering Contradiction:
Improvesealing reliabilityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple functions are merged into a single integrated device: cable separation, positioning, and sealant application are all performed by one device. The body portion contains sealant and the nozzle applies it while the cable-separating component positions cables, eliminating the need for multiple workers and complex coordinated procedures

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sealing device performs multiple functions simultaneously: it separates cables using notches, positions them in the body portion, stores sealant in internal cavities, and applies sealant through the nozzle. This multi-functionality simplifies the installation process to a single operator while maintaining reliable sealing

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

3Reliability

If sealant is applied without precise positioning, then sealing can be achieved, but adhesion issues occur due to temperature effects and lack of visual inspection

Engineering Contradiction:
Improveadhesion qualityVSAvoidsealant application precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The device replaces manual, imprecise sealant application with a controlled nozzle system that delivers sealant precisely to the intended location. The nozzle assembly provides mechanical precision in positioning and application, eliminating adhesion issues caused by improper application and making visual inspection unnecessary

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
