Rubber Mounting Base with Embedded Reinforcement for Tire Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing functional component mounting bases for tires concentrate load on the wall portion opposite to the load direction, leading to potential breakage and detachment of attached components due to unbalanced inertial forces during vehicle travel.
Innovation Solution
A rubber-based functional component attaching member with a recessed portion and embedded reinforcing material that distributes load to portions other than the wall opposite to the load direction, enhancing durability by dispersing inertial forces across the outer circumferential wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the functional component mounting base is made of rubber with a recessed portion for attaching the functional component, then the functional component can be securely attached to the inner surface of the tire, but the load concentrates on the wall portion opposite to the load direction, reducing durability
Solution Approach 1:
The patent embeds a reinforcing material (such as metal mesh, fabric, or molded resin) within the rubber mounting base to create a composite structure. This reinforcing material forms a load distribution framework that prevents stress concentration on the opposite wall portion, while the rubber material continues to provide secure attachment through the recessed portion. The combination of materials resolves the contradiction by maintaining attachment security while improving durability against inertial forces during vehicle travel.
2Device complexity
If the mounting base structure is simplified without reinforcing material, then the device complexity is reduced, but the load concentration causes the functional component to detach at high speeds
Solution Approach 1:
The patent incorporates a reinforcing material embedded in the rubber mounting base to create a composite structure that maintains relative simplicity while significantly improving high-speed durability. The reinforcing material forms an internal framework that distributes inertial forces without requiring complex external structures or additional attachment mechanisms. This resolves the contradiction by maintaining structural simplicity from the outside while internally preventing component detachment at high speeds through the load-distributing composite structure.

AI summary
In order to provide a functional component attaching member of which durability can be further improved because when a load is applied to a functional component while a vehicle is travelling, the load can also be borne by portions other than a wall portion opposite to a load direction, the present invention provides a rubber functional component attaching member (functional component mounting base 1) for fastening a functional component 29 to an inner surface 70 of a tire, comprising a bottom surface 4 that is fixed to the inner surface 70 of the tire, an attaching portion 2 having a recessed portion 2A to which a functional component-side attaching portion 30 provided to the functional component 29 is attached, and a reinforcing material 20 embedded in a rubber portion on an outer side of the recessed portion 2A.
