Solution Overview

Problem

Foldable all terrain vehicles have limited storage space and increased space occupation when folded, making them less convenient for use.

Innovation Solution

A foldable all terrain vehicle design featuring a base support with rotatable bottom rods, X-shaped movable frames, and movable wheels, which allows for improved stability and increased storage capacity while reducing the space occupied when folded.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the storage space is increased, then the storage capacity is improved, but the space occupied when folded increases

Engineering Contradiction:
Improvestorage capacityVSAvoidspace occupied when folded
Core Design Contradiction:
Quantity of substanceVSVolume of moving object

Solution Approach 1:

The patent implements nesting by placing the storage space within the folded structure of the all terrain vehicle. The storage compartment is integrated into the folded configuration of the frame and wheels, allowing items to be stored within the compacted form factor rather than requiring additional external space. This resolves the contradiction by enabling increased storage capacity without proportionally increasing the folded volume.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent employs dynamic reconfiguration of the vehicle structure during folding and unfolding operations. The frame members and wheels are designed to move relative to each other in a controlled manner, transforming the vehicle between an extended operational state and a compact folded state. This dynamic transformation allows the storage space to be accessible during use while maintaining a compact form when folded, resolving the space contradiction.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the vehicle is designed for folding, then the convenience of use is improved, but the stability during movement deteriorates

Engineering Contradiction:
Improveconvenience of useVSAvoidstability during movement
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent divides the all terrain vehicle into segmented components including the frame, wheels, and storage space, each capable of independent movement and reconfiguration. The frame is divided into multiple connected segments that can fold relative to each other, while the wheels are separable from the main body. This segmentation enables easy folding for convenience while allowing the components to be rigidly connected during movement to maintain stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic connection mechanisms that transition between rigid and flexible states. During movement, the connection elements maintain rigid connectivity to ensure stability. During folding operations, the same connections allow controlled relative movement between segments. This dynamic behavior resolves the contradiction by providing both stability during use and ease of folding when needed.

Inventive Principle:
Principle #15Dynamics
