Solution Overview

Problem

Existing methods for attaching sensor containers to tires using adhesives face issues such as void formation, adhesive peeling, and environmental pollution, leading to inaccurate sensing and safety risks during high-speed driving, with complex processes complicating adhesive-free solutions.

Innovation Solution

A method involving curing a container unit with a dummy material, attaching it to the tire, curing the tire, removing the dummy, and inserting the sensor without adhesive, using a rubber-based filler and urethane mixture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If adhesives are used to attach the sensor container to the inner liner, then the container can be attached, but voids form in the adhesive during high-speed driving causing the container to detach and sensor damage

Engineering Contradiction:
Improveattachment strengthVSAvoidattachment reliability
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent removes the adhesive layer from the attachment system entirely. Instead of using adhesive between the inner liner and sensor container, it introduces a dummy material that is integrated into the tire structure during vulcanization, eliminating the adhesive-related void formation and detachment problems.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a dummy material as an intermediary component between the inner liner and sensor container. This dummy material is vulcanized together with the tire, creating a reliable mechanical connection that eliminates the need for adhesive and prevents detachment during high-speed driving.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Strength

If adhesives are used for attaching the sensor container, then attachment is achieved, but environmental pollution occurs

Engineering Contradiction:
Improveattachment strengthVSAvoidenvironmental pollution
Core Design Contradiction:
StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent extracts and removes the adhesive substance from the manufacturing process. By replacing adhesive with a vulcanized dummy material integration method, the solution eliminates the environmental pollution associated with adhesive chemicals while maintaining secure attachment.

Inventive Principle:
Principle #2Taking out (Extraction)

3Object-generated harmful factors

If adhesive-free methods are used to attach the sensor container, then environmental friendliness is improved, but the manufacturing process becomes complicated

Engineering Contradiction:
Improveenvironmental pollutionVSAvoidmanufacturing process complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the dummy material attachment process with the tire vulcanization process. By integrating the dummy material into the tire structure during the same vulcanization step, the solution achieves adhesive-free attachment without adding separate manufacturing steps, thus maintaining process simplicity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent performs the attachment action preliminarily by integrating the dummy material into the tire structure before the final tire assembly. The dummy material is positioned and vulcanized in advance, creating pre-established attachment points that simplify subsequent sensor container installation.

Inventive Principle:
Principle #10Preliminary action

4Strength

If adhesive is applied to attach the sensor container, then attachment is achieved, but variations in application conditions cause inconsistent adhesion quality

Engineering Contradiction:
Improveattachment strengthVSAvoidadhesion consistency
Core Design Contradiction:
StrengthVSManufacturing precision

Solution Approach 1:

The patent removes the adhesive application step entirely, eliminating all variables related to adhesive application conditions (temperature, pressure, amount, surface preparation). The replacement vulcanization-based attachment method provides consistent results without these process variables.

Inventive Principle:
Principle #2Taking out (Extraction)
