Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If vehicles use multiple-wheel-drive mode with fixed structures, then they can drive on flat lands, but they cannot adapt to special lands like deserts or water surfaces

Engineering Contradiction:
Improveadaptability to driving conditionsVSAvoidvehicle structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The unicycle employs a transformable wheel structure that can dynamically change its configuration between land-driving mode (with external rotors engaged) and water-driving mode (with propellers engaged). This dynamic transformation allows the vehicle to adapt to different terrains without requiring multiple separate vehicles, resolving the contradiction between adaptability and structural simplicity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The single wheel is designed to perform multiple functions: it can drive on land using external rotors, drive on water surfaces using propellers, and even dive underwater. This multi-functionality eliminates the need for separate vehicles for different terrains, achieving high adaptability while maintaining a simple unicycle structure

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

2Adaptability or versatility

If vehicles are designed for land driving only, then they have simple structures, but they cannot drive on water surfaces or underwater

Engineering Contradiction:
Improveamphibious functionVSAvoidvehicle structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wheel structure is segmented into distinct functional components: external rotors for land driving, propellers for water surface driving, and an enclosed cavity for underwater operation. These segments can be independently controlled and transformed, allowing the vehicle to achieve amphibious capability while maintaining a relatively simple overall structure through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vehicle employs dynamic transformation mechanisms that allow the wheel to switch between different operational modes (land, water surface, underwater) by adjusting the configuration of external rotors and propellers. This dynamic adaptability enables amphibious function without requiring complex separate systems for each environment

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If hydrogliders are used to drive on water surface, then they can move on water, but they cannot dive underwater and require airplane-like structures

Engineering Contradiction:
Improvewater surface driving capabilityVSAvoidvehicle structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The unicycle wheel is designed to perform multiple water-related functions: it can drive on water surfaces using propellers and dive underwater by submerging the enclosed cavity. This multi-functionality eliminates the need for separate hydroglider and submarine vehicles, achieving both water surface and underwater capability in a single simple structure

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

4Adaptability or versatility

If submarines are used to dive underwater, then they can operate underwater, but they cannot drive on land or water surfaces

Engineering Contradiction:
Improveunderwater diving capabilityVSAvoidvehicle structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The unicycle wheel incorporates underwater diving capability through its enclosed cavity structure that can be submerged, while simultaneously retaining land-driving capability through external rotors and water-surface driving capability through propellers. This universal design eliminates the need for separate submarine, hydroglider, and land vehicle, achieving all three functions in a single simple structure

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