Solution Overview

Problem

Existing methods for attaching tire-mounted sensor packages to tire innerliners lack a robust and secure connection while maintaining the ability to remove the packages easily.

Innovation Solution

The use of an attachment patch with a central opening smaller than the peripheral flange of a mount, which is affixed to the tire using a resilient material, such as rubber, either through adhesive or cold curing, to securely hold the sensor package in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional fasteners (hook and loop, threaded connectors, clamps, pins, snap-fit structures) are used to attach TMS packages to the innerliner, then the attachment can be removed, but the connection is not robust and secure enough

Engineering Contradiction:
Improveconnection securityVSAvoidremovability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The attachment system is divided into two distinct segments: a permanent attachment patch affixed to the innerliner and a removable TMS package with a mount. This segmentation allows the patch to provide secure permanent attachment while the package can be independently removed, resolving the contradiction between connection security and removability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The attachment patch is pre-affixed to the innerliner before the TMS package is installed. This preliminary action creates a secure base attachment that ensures robust connection, while the subsequent installation of the package maintains the ability to remove the complete assembly when needed.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the central opening of the attachment patch is smaller than the peripheral flange of the mount, then the mount is securely held, but the attachment patch requires precise positioning

Engineering Contradiction:
Improvemount securityVSAvoidpositioning accuracy
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The elastomeric material of the attachment patch serves as an intermediary between the mount and the innerliner. This compliant intermediate layer compensates for positioning variations by deforming to accommodate slight misalignments, allowing the smaller central opening to securely hold the peripheral flange without requiring extremely precise positioning.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The attachment patch utilizes changes in the physical state of elastomeric material (from soft/compliant during installation to firm upon curing) to accommodate positioning variations during installation while providing secure holding force once attached. This parameter change allows tolerance for positioning imprecision while maintaining mount security.

Inventive Principle:
Principle #35Parameter changes

AI summary

An assembly for mounting an electronics package to a tire includes an electronics package, a mount with a peripheral flange, and an attachment patch. The electronics package is connected to the mount, which is in contact with the tire. The attachment patch is connected to the mount and includes a central opening that it smaller than the peripheral flange. The attachment patch is further affixed to the tire.
