Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire protection devices for off-road vehicles are complex and time-consuming to install, requiring numerous parts and screws, which complicates their mounting and dismounting, especially in field operations.
Innovation Solution
A tire protection device featuring a shield with an annular shape made of polymer material and a crown with integral connecting and mounting parts, including ear-shaped protuberances for secure attachment to the rim, reducing the number of parts and screws needed, and utilizing textile threads for a screw-free connection, enhancing robustness and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-part protection device with separate ring and mounting components is used, then the protection device can be assembled from individual parts, but the device complexity increases and installation time increases
Solution Approach 1:
The patent combines the ring and mounting components into a single integral crown structure. The crown is formed as one piece with the shield, eliminating the need for separate ring and mounting parts that were previously connected by screws. This merging reduces the number of components and simplifies the overall device structure while maintaining the protective function.
Solution Approach 2:
The integral crown structure serves multiple functions simultaneously: it provides the protective ring structure and integrates the mounting functionality through built-in mounting elements. The ear-shaped protrusions on the crown serve as both structural features and mounting attachment points, combining what were previously separate functions into a single multi-functional component.
2Ease of manufacture
If a protection device with separate ring and mounting parts connected by screws is used, then the components can be independently manufactured, but the number of parts increases and installation becomes time-consuming
Solution Approach 1:
The crown is manufactured as a single integral piece with the shield, eliminating the need for separate manufacturing and assembly of ring and mounting components. This reduces the total number of parts from multiple separate components to a unified structure, significantly reducing installation time while the shield itself can still be manufactured using standard polymer processing methods.
3Reliability
If multiple screws are used to fix the protection device to the rim, then the device can be securely mounted, but the number of fastening elements increases and assembly complexity increases
Solution Approach 1:
The mounting elements are integrated directly into the crown structure as ear-shaped protrusions with built-in attachment features. This eliminates the need for separate screws and fastening elements, reducing the number of components while maintaining secure mounting through the integral design of the crown and rim connection points.
4Adaptability or versatility
If a complex multi-part protection device is used, then the device can be assembled from standard components, but the assembly and disassembly time increases
Solution Approach 1:
The shield and crown are combined into a single integral structure, reducing the number of assembly steps from assembling multiple separate components to installing one unified device. This significantly increases assembly speed and productivity while the device remains adaptable to different rim configurations through the design of the mounting elements.
