Flexible Wheel Assembly with Replaceable Tread
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle tires with air-inflated components are prone to punctures and require frequent replacement due to wear, leading to issues with flat tires and improper inflation, which affect vehicle performance.
Innovation Solution
A flexible wheel assembly with a replaceable outer tread, comprising a wheel disk and a tread member made of resilient materials, that deforms to maximize contact area with the driving surface without air inflation, allowing for secure fastening and easy replacement of the tread member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air-inflated tire components are used, then shock absorption and shape conformity are improved, but puncture risk and flat tire concerns increase
Solution Approach 1:
The tire is divided into separate replaceable components: an inner wheel assembly and an outer tread component. This segmentation allows the tread to be replaced independently when worn, eliminating the need to replace the entire tire and improving reliability without requiring air-inflated components.
Solution Approach 2:
The outer tread is designed as a replaceable component that can be easily removed and replaced when worn. This approach treats the tread as a consumable part, allowing continuous use of the wheel assembly by replacing only the worn tread rather than the entire tire system.
2Adaptability or versatility
If multiple tire components (treads, sidewalls, plies, liners, belts, beads) are used, then tire functionality is improved, but complexity and replacement difficulty increase
Solution Approach 1:
The tire system is segmented into two main components: a simplified inner wheel assembly and an outer tread component. This reduces the overall number of components compared to conventional tires while maintaining essential functionality through the resilient material properties of the outer tread.
Solution Approach 2:
The outer tread component is designed to perform multiple functions simultaneously: providing traction, absorbing shocks through material resilience, and protecting the inner wheel assembly. This multi-functionality reduces the need for separate specialized components.
3Strength
If air-inflated components are used, then cushioning is improved, but inflation maintenance and performance consistency become problematic
Solution Approach 1:
The air-inflation system is replaced with a solid resilient material system. The outer tread is made from elastomeric or polymeric materials that provide cushioning through their inherent material properties rather than through pressurized air, eliminating the need for inflation maintenance while maintaining shock absorption capabilities.

AI summary
A wheel assembly comprising a wheel disk and a tread member disposed around the wheel disk. The wheel disk can have a substantially conical shape when in an unloaded state, but be flexible such that it can deform under load to optimize and/or maximize contact area between the tread member and a driving surface.
