Emergency Wheel Attachment With Movable Tread for Flat Tires
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle wheel attachments fail to provide a low-wear, high-comfort solution for driving with a flat tire or in adverse conditions like ice or snow, as they often suffer from wear issues and lack effective traction and stability.
Innovation Solution
The proposed attachment features a rim with a stationary section and a movable tread section that can be clamped to the wheel, incorporating heat-conducting elements and a damping system, along with a clamping device that ensures secure fastening and easy assembly, allowing for efficient operation on various road surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing vehicle wheel attachments are used for driving with flat tire or adverse conditions, then driving capability is enabled, but wear resistance is poor and comfort is low
Solution Approach 1:
The attachment is divided into a stationary section (mounting portion) and a movable tread section, allowing differential movement and wear distribution. The stationary section remains fixed to the wheel while the tread section can move and self-adjust, reducing concentrated wear on any single component.
Solution Approach 2:
The tread section is designed to be movable relative to the stationary section, enabling dynamic adaptation to road conditions. This mobility allows the tread to self-adjust and distribute wear more evenly, improving overall durability while maintaining driving capability.
2Ease of operation
If existing vehicle wheel attachments are used for driving with flat tire, then mobility is restored, but driving comfort is poor
Solution Approach 1:
The movable tread section dynamically adapts to road irregularities and vehicle movement, absorbing shocks and vibrations that would otherwise transmit directly to the vehicle. This dynamic behavior restores mobility while significantly improving driving comfort.
Solution Approach 2:
The attachment design inherently provides cushioning through the movable tread section that can deflect and absorb impacts before they reach the vehicle. This prior cushioning effect mitigates the harshness of driving on imperfect surfaces.
3Reliability
If clamping means engage behind rim section, then secure fastening is achieved, but assembly complexity increases
Solution Approach 1:
The attachment is segmented into stationary and movable sections that can be assembled independently. The clamping means are integrated into the stationary section, which is first mounted to the wheel, simplifying the overall assembly process while maintaining secure fastening.
Solution Approach 2:
The clamping means are designed to automatically engage and secure the attachment to the wheel rim when the attachment is mounted. This self-securing mechanism reduces assembly complexity by eliminating the need for additional fastening operations or complex adjustment procedures.
