Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the storage capacity of electrical energy is increased to extend operating time, then the operating time is extended, but the weight and volume of the system increase

Engineering Contradiction:
Improveoperating timeVSAvoidweight of energy storage system
Core Design Contradiction:
Duration of action of moving objectVSWeight of moving object

Solution Approach 1:

The patent combines multiple energy conversion mechanisms (wind energy conversion, kinetic energy recovery, and potential energy storage) into a single integrated energy supply system. The wind turbine converts wind energy to electrical energy, the regenerative brake recovers kinetic energy during deceleration, and the spring mechanism stores potential energy, all working together to extend operating time without requiring a single large-capacity storage system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The energy supply system performs multiple functions simultaneously: it generates electrical energy from wind, recovers kinetic energy during braking, stores mechanical energy in springs, and provides mechanical propulsion. This multi-functionality allows the system to extend operating time while keeping the overall weight manageable by sharing common components across different energy conversion pathways.

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

2Duration of action of moving object

If the storage capacity of electrical energy is increased to extend operating time, then the operating time is extended, but the volume of the system increases

Engineering Contradiction:
Improveoperating timeVSAvoidvolume of energy storage system
Core Design Contradiction:
Duration of action of moving objectVSVolume of moving object

Solution Approach 1:

The patent merges wind energy conversion, kinetic energy recovery, and potential energy storage into one integrated system. The wind turbine, regenerative brake, and spring mechanism work together to provide multiple energy sources, extending operating time without requiring a single large-volume electrical storage system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The spring mechanism provides mechanical energy storage through elastic deformation, offering a compact volume alternative to large electrical battery systems. The mechanical spring can store significant energy in a small volume, contributing to extended operating time without increasing system volume.

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Duration of action of moving object

If a complex energy supply system is implemented to extend operating time, then the operating time is extended, but the device complexity increases

Engineering Contradiction:
Improveoperating timeVSAvoidcomplexity of energy supply system
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The patent integrates wind energy conversion, kinetic energy recovery, and potential energy storage into a unified energy supply system. By combining these functions into one coordinated system rather than separate systems, the patent extends operating time while managing overall complexity through shared control and integration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The energy supply system is designed to perform multiple functions through integrated components that serve both energy generation and storage purposes. This multi-functionality reduces the need for separate dedicated systems, thereby extending operating time while controlling the increase in device complexity.

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