Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If an internal combustion engine is used to drive the mixing wagon, then the wagon can be powered and moved, but environmental impact increases due to pollutant emissions and noise

Engineering Contradiction:

Improvepower sourceVSAvoidpollutant emissions

Core Design Contradiction:

Use of energy by moving objectVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the internal combustion engine (mechanical/chemical system) with an electric motor (electrical system). The electric motor is connected to the mixing auger via a drive shaft, eliminating combustion-related pollutants while maintaining the mechanical mixing function. This substitution directly addresses the environmental impact issue while preserving the wagon's operational capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Use of energy by moving object

If an internal combustion engine is used to drive the mixing wagon, then the wagon can be powered and moved, but noise pollution increases

Engineering Contradiction:

Improvepower sourceVSAvoidnoise

Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the noisy internal combustion engine with a quiet electric motor. The electric motor operates without combustion, significantly reducing noise emissions. This substitution maintains the drive function while eliminating the harmful noise factor, making the mixing wagon more suitable for use near livestock and in quiet environments.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Use of energy by moving object

If an internal combustion engine is used, then the wagon can be powered, but efficiency decreases due to limited ability to vary power output

Engineering Contradiction:

Improvepower sourceVSAvoidoperational efficiency

Core Design Contradiction:

Use of energy by moving objectVSProductivity

Solution Approach 1:

The patent employs an electric motor with variable speed capability, allowing dynamic adjustment of power output to match actual mixing requirements. The motor can operate at different speeds (e.g., 500-1500 RPM) depending on the mixing stage and material viscosity, optimizing energy efficiency. This dynamic control is superior to the fixed or limited speed control of internal combustion engines.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of the drive system by using an electric motor that can be precisely controlled in terms of speed, torque, and power delivery. The motor can be controlled to provide optimal power at different mixing stages, improving overall system efficiency compared to the less flexible internal combustion engine.

Inventive Principle:

Principle #35Parameter changes

4Use of energy by moving object

If an internal combustion engine is used, then the wagon can be powered, but risk of contamination increases due to pollutant emissions affecting feed quality

Engineering Contradiction:

Improvepower sourceVSAvoidfeed quality

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent replaces the polluting internal combustion engine with an electric motor that emits no combustion byproducts. This eliminates the risk of exhaust contaminants (CO, NOx, particulate matter) entering the feed mixture, thereby improving feed quality and animal health while maintaining the wagon's operational reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
