Solution Overview

Problem

Current cable plow systems are complex to transport due to the need for heavy-duty cranes to load and unload the chassis and cable plow, requiring laborious separation and reassembly, and lack a simple method for coupling and uncoupling.

Innovation Solution

A cable plow system with a coupling device allowing interchangeable connection between the chassis and cable plow, featuring eye-bolt connections and adjustable supports for easy separation and reconnection, enabling self-propelled chassis operation and reduced reliance on heavy-duty cranes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the cable plow is integrated with the chassis as a fixed unit, then structural stability is improved, but transport complexity and crane dependency increase

Engineering Contradiction:
Improvestructural stabilityVSAvoidtransport complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The cable plow system is divided into two independent segments: the chassis and the cable plow. The chassis can be separated from the cable plow using a coupling device, allowing each component to be transported independently. This segmentation eliminates the need for heavy-duty cranes during transport while maintaining structural stability when connected through the coupling mechanism.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the cable plow is separated from the chassis for transport, then transport flexibility is improved, but coupling and uncoupling time increase

Engineering Contradiction:
Improvetransport flexibilityVSAvoidcoupling time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The coupling device extracts the complex separation/reconnection process into a simple, standardized interface. The coupling mechanism allows the chassis and cable plow to be quickly connected or disconnected without requiring laborious manual assembly, reducing coupling time while maintaining transport flexibility.

Inventive Principle:
Principle #2Taking out (Extraction)

3Force

If heavy-duty cranes are used for loading and unloading, then lifting capacity is improved, but equipment requirements and operational complexity increase

Engineering Contradiction:
Improvelifting capacityVSAvoidequipment requirements
Core Design Contradiction:
ForceVSDevice complexity

Solution Approach 1:

The chassis is equipped with a self-propelled capability and an integrated coupling device that enables it to load and unload the cable plow independently without external heavy-duty cranes. The chassis uses its own propulsion system and coupling mechanism to perform the loading/unloading operations, eliminating the need for additional lifting equipment.

Inventive Principle:
Principle #25Self-service
