Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional trenching systems use cutter teeth on a rotating chain, then the system can remove geologic material, but the operation speed is slow and maintenance is difficult

Engineering Contradiction:
Improvematerial removal speedVSAvoidmaintenance difficulty
Core Design Contradiction:
ProductivityVSEase of repair

Solution Approach 1:

The patent replaces the mechanical cutter teeth system with a plasma torch system that uses thermal energy to melt and remove geologic material. The plasma torch generates a high-temperature plasma jet that directly melts the material, eliminating the need for mechanical cutting components that require frequent maintenance and replacement.

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

Solution Approach 2:

The invention changes the operating parameters from mechanical force and rotation speed to plasma temperature and power output. By controlling plasma parameters such as temperature, power, and flow rate, the system achieves high material removal speeds while maintaining ease of operation through electronic control rather than mechanical adjustment.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If conventional trenching systems use cutter teeth on a rotating chain, then the system can cut through ground, but the operation is difficult to maintain

Engineering Contradiction:
Improveoperational simplicityVSAvoidmaintenance difficulty
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The patent replaces the complex mechanical rotating chain with cutter teeth system with a plasma torch system controlled by electronic systems. This substitution eliminates mechanical wear, friction, and alignment issues, significantly reducing maintenance requirements while simplifying operation through electronic controls.

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

Solution Approach 2:

The plasma torch system serves multiple functions: cutting, melting, and removing geologic material, whereas the conventional system required separate components for each function. This multi-functionality reduces the number of parts that need maintenance and simplifies the overall operational procedure.

Inventive Principle:

Solution Approach 1:

The patent replaces mechanical position and angle control mechanisms with electronic control systems that use sensors, actuators, and control algorithms to achieve precise positioning and angular control of the plasma torch, significantly improving precision while reducing mechanical complexity.

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

Solution Approach 2:

The system incorporates feedback mechanisms through sensors that monitor the position and angle of the plasma torch, providing real-time data to the control system. This feedback enables automatic adjustment and correction, achieving high precision control without complex mechanical positioning mechanisms.
