Emergency Wheel Attachment Assembly Without a Car Jack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle wheel attachments fail to provide a secure and easy assembly method for enabling driving with a restricted tire function, such as a flat tire, without the need for a car jack or lifting platform, and often result in incorrect assembly.
Innovation Solution
A vehicle wheel attachment system comprising a detachable tread section and initial mounting section with clamping devices that engage behind the rim flange, allowing for secure fastening without a car jack, featuring pivotable hook elements and a spring-preloaded locking mechanism for stability and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing attachment methods are used, then assembly can be performed without a car jack, but the assembly is not secure and may be incorrect
Solution Approach 1:
The attachment is divided into an initial mounting section and a tread section that can be assembled in stages. The initial mounting section is first secured to the rim using clamping devices, providing a stable base. Then the tread section is attached to this mounting section, allowing secure assembly even on a flat tire without requiring a car jack or lifting platform.
Solution Approach 2:
The clamping devices are designed to preliminarily secure the initial mounting section to the rim flange before the tread section is attached. This preliminary securing action creates a stable foundation that prevents incorrect assembly and ensures reliability, while still allowing the entire process to be completed without external lifting equipment.
2Device complexity
If the attachment is designed as a single integrated piece, then assembly is simple, but it cannot be securely fastened without a car jack
Solution Approach 1:
The attachment is segmented into two main parts: the initial mounting section with clamping devices and the tread section. This segmentation allows the mounting section to be independently secured to the rim using the clamping devices that engage behind the rim flange, providing secure fastening without requiring a car jack. The separated design enables each section to be optimized for its specific function while maintaining overall simplicity.
