Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If fossil fuels are used to generate electric power, then power generation efficiency is improved, but pollutants are discharged

Engineering Contradiction:

Improvepower generation efficiencyVSAvoidpollutants

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent converts non-uniform energy input (which would normally cause operational instability) into a benefit by using a flywheel to store kinetic energy during high-input periods and release it during low-input periods, thereby maintaining uniform power output from the electrostatic generator while using eco-friendly energy sources

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Object-generated harmful factors

If solar power, water power, or wind power generators are used, then eco-friendly power generation is achieved, but they must be manufactured in large size

Engineering Contradiction:

Improvepollutant emissionVSAvoidgenerator size

Core Design Contradiction:

Object-generated harmful factorsVSVolume of moving object

Solution Approach 1:

The patent segments the power generation system into distinct functional modules: an electrostatic generator for power conversion, a flywheel for energy storage and smoothing, and a converter with variable gear ratios. This modular segmentation enables compact design while maintaining efficient power generation from eco-friendly sources

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a flywheel as an intermediary energy storage device between the eco-friendly power source and the electrostatic generator. The flywheel absorbs kinetic energy fluctuations and provides uniform rotational energy to the generator, enabling compact design without sacrificing power output consistency

Inventive Principle:

Principle #24Intermediary (Mediator)

3Object-generated harmful factors

If solar power, water power, or wind power generators are used, then eco-friendly power generation is achieved, but power output becomes non-uniform

Engineering Contradiction:

Improvepollutant emissionVSAvoidpower output uniformity

Core Design Contradiction:

Object-generated harmful factorsVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by using the flywheel to pre-store kinetic energy during periods of high energy input and pre-release it during low input periods, thereby proactively maintaining uniform power output before fluctuations occur. The converter also pre-adjusts gear ratios to optimize energy transmission

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback control through the converter system that monitors the rotational speed of the flywheel and dynamically adjusts the gear ratio selection to maintain constant output speed to the electrostatic generator, ensuring stable power output despite variable input conditions

Inventive Principle:

Principle #23Feedback

4Stability of the object's composition

If a converter with multiple gear sets and connection members is added, then constant rotation speed is achieved, but device complexity increases

Engineering Contradiction:

Improverotation speed constancyVSAvoidconverter structure

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the gear ratio selection variable rather than fixed. The converter dynamically switches between different gear sets based on operational conditions, allowing the system to adapt to varying input speeds while maintaining constant output speed, thereby reducing overall structural complexity compared to a single complex gear train

Inventive Principle:

Principle #15Dynamics
