Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle wheel systems lack an effective solution for enabling safe and efficient driving with a flat tire or in adverse conditions such as ice or snow, as traditional spare wheels are cumbersome and not adaptable to different rim diameters.
Innovation Solution
A compact attachment system for vehicle wheels featuring a circular base body with a fastening device that includes detachable, spring-mounted fastening means and a coupling mechanism, allowing for secure mounting on various rim diameters and conditions, with a tread body for improved traction and shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional spare wheel is used, then driving capability is restored, but the device becomes cumbersome and storage space is consumed
Solution Approach 1:
The attachment is divided into a base body and separate fastening means that can be detachably connected. The fastening means can be stored separately when not in use, reducing the space required for storage while maintaining the ability to restore driving capability when needed.
Solution Approach 2:
The fastening means are designed to be detachably connectable to the base body, allowing them to be nested or stored in a compact manner when not in use, thereby reducing overall device complexity and storage requirements while preserving full functionality when deployed.
2Ease of operation
If a fixed fastening system is used, then mounting is simple, but adaptability to different rim diameters is lost
Solution Approach 1:
The fastening means are designed with movable elements that can be displaced radially to adapt to different rim diameters. This dynamic adjustment capability allows the same attachment to be mounted on various rim sizes while maintaining a relatively simple mounting process through the use of spring-mounted mechanisms that automatically adjust.
Solution Approach 2:
The fastening device is designed to accommodate multiple rim diameters through its adjustable structure, making it a universal solution that can be used across different wheel configurations. The detachable and adjustable nature of the fastening means enables a single device to serve multiple functions and fit various applications.
3Adaptability or versatility
If spring-mounted fastening means are used, then adaptability to different rim diameters is achieved, but device complexity increases
Solution Approach 1:
The spring-mounted fastening means are designed to automatically adjust and self-align with the rim through the elastic force of the springs. This self-adjusting mechanism reduces the need for complex control systems or manual adjustments, thereby limiting the increase in device complexity while maintaining adaptability to different rim diameters.
4Device complexity
If a compact attachment is used instead of a spare wheel, then storage space is reduced, but mounting security may be compromised
Solution Approach 1:
The fastening means are pre-loaded with spring force that automatically engages when the attachment is mounted on the rim. This preliminary elastic energy storage ensures secure mounting without requiring complex locking mechanisms, maintaining mounting security while preserving the compact design of the attachment.
