Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional cable ducts are used to accommodate different cable designs, then each cable type requires a specific duct design, but this leads to high production costs and complexity

Engineering Contradiction:
Improveadaptability to different cable designsVSAvoidnumber of different duct types
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cable duct is designed as a universal module that can accommodate different cable types and configurations through adjustable elements. The duct includes adjustable support elements and routing features that can be adapted to various cable diameters, shapes, and routing requirements, eliminating the need for multiple specialized duct designs

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

Solution Approach 2:

The cable duct system is divided into modular segments that can be independently configured and assembled. Each module contains standardized connection interfaces and adjustable internal features, allowing flexible combination to meet different cable accommodation requirements while maintaining production efficiency

Inventive Principle:
Principle #1Segmentation

2Reliability

If traditional cable ducts are manufactured for each specific cable design, then cable protection is ensured, but production becomes expensive and time-consuming

Engineering Contradiction:
Improvecable protectionVSAvoidproduction cost and time
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

A single universal duct design provides adequate protection for all cable types through standardized wall thicknesses, material selections, and protective features. The universal design maintains reliable cable protection while enabling economies of scale in manufacturing, reducing both cost and production time

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

Solution Approach 2:

The duct design incorporates adjustable parameters such as support element positions, routing channel configurations, and attachment point locations that can be modified to suit different cable requirements. These parameter adjustments are achieved through simple mechanical modifications rather than complete redesigns, maintaining protection reliability while simplifying manufacturing

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple types of prefabricated cable ducts are provided for different cable types, then specific routing requirements are met, but inventory complexity and cost increase

Engineering Contradiction:
Improverouting configuration capabilityVSAvoidnumber of duct variants to stock
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The universal cable duct design incorporates adjustable routing channels and positioning features that can accommodate various cable routing configurations within a single duct type. This eliminates the need to stock multiple specialized duct variants while maintaining the ability to meet specific routing requirements through field-adjustable features

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