Solution Overview

Problem

It is difficult to distinguish the position of a communication device embedded within a tire or mounted on an inner surface of a tire from outside the tire in a dark surrounding environment.

Innovation Solution

A tire with a label area on its outer surface that indicates the position of the communication device, featuring a light emission area to facilitate identification in dark environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a communication device is embedded within the tire body or mounted on the inner surface, then the tire can perform communication functions, but the position of the communication device cannot be distinguished from outside the tire in dark environments

Engineering Contradiction:
Improvecommunication functionVSAvoidvisibility of communication device position
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies a light-emitting material to the outer surface of the tire at the position corresponding to the communication device. This material can emit light or change color to indicate the position of the communication device, making it visible from outside the tire even in dark environments. This directly addresses the visibility problem while maintaining the communication function.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent introduces a light-emitting material as an intermediary element between the communication device and the external environment. This mediator (light-emitting material) translates the position information of the embedded communication device into visible light signals that can be observed from outside the tire, solving the detection difficulty without affecting the communication device's functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the communication device is embedded within the tire body, then the tire structure remains intact, but the position indication becomes difficult in dark environments

Engineering Contradiction:
Improvetire structure integrityVSAvoidposition visibility
Core Design Contradiction:
Stability of the object's compositionVSDifficulty of detecting and measuring

Solution Approach 1:

The light-emitting material is applied to the outer surface of the tire body at the position corresponding to the embedded communication device. This material emits light or changes color to indicate the communication device position, maintaining tire structure integrity while solving the visibility issue in dark environments.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent adds a new dimension of visibility by introducing light emission properties to the tire surface. Instead of trying to make the embedded communication device visible through the tire material, the solution adds light-emitting capability at the corresponding outer surface position, creating visibility in the optical dimension without compromising structural integrity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
