Solution Overview

Problem

Existing electric self-balancing vehicles lack the ability for users to control the vehicle solely using their feet, as the foot platform is typically flat and non-rotatable, limiting control and safety during operation.

Innovation Solution

The design incorporates a rotating mechanism between the top and bottom covers, allowing the vehicle's structure to be more compact and balanced, with hub motors in the wheels and sensors for dynamic stabilization, enabling foot-controlled operation and improved safety features like friction strips and decorative lamps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the foot platform is made as a flat plate that remains horizontal, then the structure is simple and easy to manufacture, but the user cannot control the vehicle solely through feet and control versatility is limited

Engineering Contradiction:
Improvecontrol versatilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The foot platform is transformed from a static horizontal surface to a dynamic rotatable platform. The platform can rotate relative to the bottom cover, allowing it to change orientation based on user needs. This dynamic capability enables foot-only control by allowing the platform to orient in different directions while maintaining structural simplicity through the rotation mechanism.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the foot platform is made rotatable relative to the bottom cover, then foot-controlled operation is enabled and control versatility improves, but the device complexity increases

Engineering Contradiction:
Improvecontrol versatilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The vehicle body is segmented into multiple rotatable components: the top cover rotates relative to the bottom cover, and the foot platform rotates relative to the bottom cover. This segmentation allows independent rotation of different parts, enabling foot control functionality while managing overall system complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The foot platform serves multiple functions: it acts as a standing surface, a control interface for foot-operated steering, and a structural component connecting to the rotation mechanism. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving versatile foot-controlled operation.

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

3Stability of the object's composition

If the top cover and bottom cover are made rotatable relative to each other, then the vehicle achieves better balance and compactness, but the manufacturing complexity increases

Engineering Contradiction:
Improvevehicle balanceVSAvoidassembly complexity
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The top cover and bottom cover are designed to rotate relative to each other, transforming from fixed rigid components to dynamic adjustable components. This dynamic relationship allows the vehicle to achieve better balance by adjusting the orientation of covers, while the rotation mechanism is designed to be compact and manufacturable.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotation mechanism is nested within the vehicle structure, with rotational joints and bearing assemblies integrated into the cover designs. This nesting approach achieves compactness by placing rotational mechanisms inside the existing structural envelopes, while maintaining ease of manufacture through standardized nested component designs.

Inventive Principle:
Principle #7Nested doll (Nesting)
