Supplemental Tire Tread Attachment for Solid Tire Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supplemental tire treads for solid tires lack effective attachment mechanisms that prevent transverse movement and rotation, compromising traction and durability in various ground conditions.
Innovation Solution
A supplemental tire tread design featuring tire supports with receptacles that engage the solid tire's outer surface and anchor receptacles with pin anchors that pierce the tire for secure attachment, preventing relative movement and rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a supplemental tire tread is installed on a solid tire to increase surface area and traction, then the environmental impact is reduced and traction is improved, but the tread body becomes prone to relative transverse movement and rotation without effective attachment mechanisms
Solution Approach 1:
The attachment system is divided into two distinct functional components: tire supports with receptacles that prevent transverse movement, and separate anchors with receptacles that prevent rotation. This segmentation allows each component to specialize in preventing a specific type of relative motion, thereby reliably securing the tread body to the tire without compromising attachment stability.
Solution Approach 2:
The attachment mechanism addresses movement in multiple dimensions by using tire supports extending in one direction to constrain transverse movement, while anchors extending in another direction constrain rotational movement. This multi-dimensional constraint system ensures the tread body remains securely attached while maintaining improved traction through increased surface area engagement.
2Reliability
If the tread body is securely attached to prevent movement and rotation, then reliability and durability are improved, but the attachment mechanism complexity increases with multiple components
Solution Approach 1:
The attachment mechanism is segmented into distinct functional elements (tire supports, anchors, and their respective receptacles) that can be independently designed and positioned. This segmentation, while increasing component count, allows for simplified individual components that are easier to manufacture and install, offsetting the complexity through modularity and functional specialization.
Solution Approach 2:
The tread body serves multiple functions: it provides the ground-engaging surface for traction, houses the tire supports for preventing transverse movement, and contains the anchor receptacles for preventing rotation. This multi-functionality consolidates several attachment and traction functions into a single integrated component, reducing overall system complexity despite the multiple attachment elements.

AI summary
A supplemental tire tread for installation on an outer surface of a solid tire, the outer surface of the solid tire defining opposed sidewalls and a tread surface that extend between the sidewalls. The supplemental tire tread has a tread body having an outer tread surface, an inner surface, and an attachment for attaching the tread body around the tread surface of the tire. The inner surface of the tread body has tire supports with tire receiving receptacles that open away from the inner surface of the tread body and receive the solid tires when installed. The tread body has anchor receptacles that engage anchors that pierce the solid tires to support the tread body against relative rotation of the solid tire and the tread body.
