Solution Overview

Problem

Existing vehicle wheel attachment solutions require removal of the wheel or use of a jack to install a spare wheel, complicating the process and requiring more effort and time, especially when the tire is flat.

Innovation Solution

A foldable attachment with a base body comprising a mounting section and a tread section, where the tread section has an interruption that allows for easy alignment and assembly without removing the wheel, enabling the attachment to be securely fastened to the vehicle wheel without a jack, using a positioning device and fastening mechanism for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional spare wheel installation method is used, then the wheel can be securely attached to the vehicle, but the wheel must be removed or the vehicle must be lifted with a jack, complicating the process

Engineering Contradiction:
Improveease of installationVSAvoidinstallation process complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The attachment device is divided into a mounting section and a running surface section that can be independently positioned and assembled. The mounting section attaches to the wheel hub first, then the running surface section is aligned and secured, allowing step-by-step installation without removing the wheel or using a jack

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting section is pre-attached to the wheel hub before the vehicle is lifted, establishing a stable base. This preliminary action allows the running surface section to be subsequently aligned and secured in place without requiring the wheel to be removed or the vehicle to be fully lifted

Inventive Principle:
Principle #10Preliminary action

2Volume of moving object

If the attachment is designed to be compact for storage, then it saves space, but it may compromise the structural integrity or secure attachment capability

Engineering Contradiction:
Improvestorage volumeVSAvoidattachment reliability
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The attachment device features a foldable mounting section that can be collapsed into a compact configuration for storage, yet extends to a stable, load-bearing structure during installation and use. The running surface section can be positioned at different angles and securely locked in place, providing both compact storage and reliable attachment

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The running surface section can be positioned within or adjacent to the mounting section when not in use, creating a nested compact configuration. The mounting section's foldable structure allows it to collapse around the running surface section, minimizing storage volume while maintaining structural integrity when deployed

Inventive Principle:
Principle #7Nested doll (Nesting)
