Modular Tire Surface Assembly for Fast Seasonal Tread Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire adaptation systems require significant effort and equipment for installation and removal, especially in winter conditions where rapid tire changes are necessary for safety and mobility.
Innovation Solution
A surface adapting assembly for a tire comprising an elongate member with a contact surface, sidewalls, and end surfaces, secured using fastening elements and a locking element that allows for quick and efficient fitting and removal without the need for complete wheel removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tire replacement methods are used (jack, wheel brace, complete wheel removal), then the tire can be securely replaced, but the process requires significant equipment, time, and effort
Solution Approach 1:
The tire system is divided into two independent parts: the base tire and the interchangeable tread element. This allows the tread to be replaced without removing the entire wheel assembly, eliminating the need for jacks and wheel braces while maintaining secure attachment through the fastening elements that engage with the base tire structure
Solution Approach 2:
The tire system transitions from a static complete wheel assembly to a dynamic modular system where the tread element can be quickly exchanged. The fastening elements with locking mechanisms enable the tread to be securely attached and rapidly removed without permanent fastening, allowing adaptive response to changing road conditions
2Adaptability or versatility
If the entire wheel is removed for tire replacement, then the tire can be changed, but the vehicle cannot be moved during the replacement process
Solution Approach 1:
By segmenting the tire into a base tire and a separate tread element, the replacement process only requires removing the tread element rather than the entire wheel. This allows the vehicle to remain on the ground and potentially be moved or repositioned during the tread exchange process
Solution Approach 2:
The fastening elements are pre-positioned on the base tire, allowing the tread element to be quickly snapped into place without requiring complex assembly steps. This preliminary preparation of the fastening system enables rapid tread exchange while the vehicle remains stationary or can be moved
3Ease of manufacture
If specialized equipment is carried for tire replacement, then complete tire replacement can be performed, but the equipment adds weight and requires storage space
Solution Approach 1:
The heavy specialized equipment (jacks, wheel braces) is extracted from the system and replaced with a lightweight fastening mechanism integrated into the tread element itself. The fastening elements with locking mechanisms provide sufficient attachment capability without requiring external heavy equipment for installation or removal
Solution Approach 2:
The tread element is designed with self-contained fastening elements that enable the user to install and remove the tread without external tools or equipment. The locking mechanisms are integrated into the tread structure, allowing the tread to secure itself to the base tire and be released without specialized replacement equipment

AI summary
A surface adapting assembly for a tire comprising an elongate member for fitting over the tire. The elongate member has a contact surface having treads sidewalls extending longitudinally and extending between respective edges of the elongate member and respective sides of the contact surface, and a first and second end extending in a crosswise direction of the member. The surface adapting assembly comprises a first pair of fastening elements attached to the first sidewall adjacent the first edge and adjacent each end of the elongate member. Each fastening element has a height that is smaller than the distance across the sidewall from the first edge to the contact surface. At least one of the first pair of fastening elements comprises an opening for a part of the same locking element. A method for manufacturing a surface adapting assembly for a tire is also disclosed.
