Innovation Solution

A multi-layered reflective coating is applied to the inner surface of retread tires, comprising a primer layer for strong adhesion, a reflective layer with microglass beads and aluminum-coated prismatic particles for enhanced visibility, and an optional topcoat for durability and protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If retread tires are used to extend tire life and reduce costs, then productivity and cost-effectiveness are improved, but the risk of tire detachment and debris formation increases

Engineering Contradiction:

Improvetire life extensionVSAvoidroad debris hazard

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful effect of tire debris (which causes safety hazards) into a beneficial effect by applying reflective coating to the debris. The coating makes the debris visible through light reflection, transforming the invisible hazard into a detectable object that drivers can avoid, thus converting the harm of debris presence into a safety benefit

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent applies reflective and photoluminescent coatings that change the optical properties of the tire debris. The coating materials reflect light during the day and emit light at night, creating visible color changes that make the debris detectable against the road background, solving the visibility problem without affecting the retread tire's functional performance

Inventive Principle:

Principle #32Color changes

2Object-affected harmful factors

If tire fragments are dark rubber material, then they blend into the road surface, but this causes severe visibility issues under low-light conditions

Engineering Contradiction:

Improvevisibility of debrisVSAvoidlow-light detection

Core Design Contradiction:

Object-affected harmful factorsVSIllumination intensity

Solution Approach 1:

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent introduces light-reflecting and light-emitting materials as intermediaries between the tire debris and the driver's vision. These coating materials act as mediators that capture light and redirect it to drivers' eyes, enabling detection of the debris without requiring direct illumination of the debris itself

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If reflective coating is applied to enhance visibility of tire fragments, then road safety is improved, but the complexity of the retread process increases

Engineering Contradiction:

Improveroad safetyVSAvoidcoating application process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies the reflective coating to the tire surface before the retreading process begins. By performing the coating application in advance, the patent eliminates the need for additional coating steps during or after retreading, thus improving safety without adding complexity to the retread process itself

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent develops a coating system that serves multiple functions: it provides visibility enhancement through light reflection, protects the tire surface, and maintains adhesion through the retread process. This multi-functionality reduces the need for separate treatments and simplifies the overall process while achieving safety goals

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A reflective coating device and method of use is provided. The device is comprised of a visibility-enhancing coating for retread tires, comprising a multi-layered reflective coating that aids in locating tire fragments on roadways. The device features a primer layer that strongly bonds to the tire rubber, followed by a reflective layer containing microglass beads and aluminum-coated prismatic particles within a binding matrix to ensure consistent reflectivity and durability under wear. High-contrast pigments and UV-stable agents improve visibility and prevent color fading, while optional photoluminescent materials provide passive glow in darkness. An optional topcoat layer shields the reflective layer from abrasion, moisture, and UV damage, enhancing the device's durability in harsh environments. A method for applying the device on tire surfaces ensures long-lasting performance, maintaining visibility under various conditions to enhance road safety.
