Solution Overview

Problem

Existing tire manufacturing methods lack the flexibility to embed electronic components, such as RFID tags, at various positions within the tire structure, limiting their placement and functionality.

Innovation Solution

A tire manufacturing method that involves winding rubber strips in a spiral manner with overlapping regions, allowing for the embedding of electronic components at desired positions between layers or within the overlapping areas, enabling precise control over the embedding depth and arrangement of RFID tags or other electronic components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the electronic component is arranged at a boundary surface between two different substances, then it is possible to carry out production management and usage history management, but the electronic component cannot be embedded at any position among rubber components constituting the tire

Engineering Contradiction:

Improveembedding position flexibilityVSAvoidarrangement structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transitions from arranging electronic components only at boundary surfaces (2D surface arrangement) to embedding them at any position within the 3D volume of rubber components. This is achieved by introducing a winding structure with multiple layers and overlapping regions, creating a three-dimensional embedding space that allows flexible positioning of electronic components throughout the tire structure.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent implements nesting by placing electronic components within the overlapping regions of wound rubber strips or between layers of the winding structure. The electronic components are embedded within the rubber layers themselves, creating a nested configuration where the component is surrounded and protected by multiple layers of rubber material.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Manufacturing precision

If the electronic component is embedded in the tire, then production management and shipping management can be carried out, but the embedding position cannot be adjusted from the tire outer surface

Engineering Contradiction:

Improveembedding depth controlVSAvoidmanufacturing process

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent applies preliminary action by arranging electronic components on the winding structure during the manufacturing process, before the tire is fully assembled and vulcanized. The components are positioned on the rubber strips or at overlapping regions during the winding stage, allowing precise control of embedding depth and position before the rubber sets into its final form.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces dynamics by making the embedding depth adjustable during the winding process. The winding structure allows the electronic components to be positioned at different depths by controlling the number of layers and overlapping regions, enabling flexible adjustment of embedding position from the outer surface based on functional requirements.

Inventive Principle:

Principle #15Dynamics

3Reliability

If the electronic component is arranged at a boundary surface, then communication can be carried out, but the component lacks protection and is vulnerable to damage during tire deformation

Engineering Contradiction:

Improvecomponent protectionVSAvoiddamage risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements beforehand cushioning by surrounding electronic components with multiple layers of rubber material through the winding structure. The overlapping regions and inter-layer positioning create a cushioning effect that protects the components from mechanical stress, deformation, and external impacts during tire usage, reducing the risk of damage before it occurs.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The patent uses composite materials by combining electronic components with multiple layers of rubber material in a wound structure. The resulting composite structure integrates the electronic component within the rubber layers, creating a unified assembly where the rubber provides mechanical protection while the electronic component maintains its functional properties.

Inventive Principle:

Principle #40Composite materials

AI summary

In a manufacturing method of a tire which manufactures a side-wall rubber as a constituent member of the tire by winding a rubber strip formed of unvulcanized rubber on a carcass ply serving as a rotating body, the method includes the steps of: winding the rubber strip prior to vulcanization in a spiral manner having a partially overlapping region, so that at least part thereof is exposed at an outer surface, and another portion thereof is covered by the rubber strip after being wound; and arranging an electronic component so that the electronic component is positioned in the partially overlapping region of the rubber strip or between the carcass ply, etc. serving as the lower layer member of the rubber strip and the rubber strip, in the winding step or an earlier step thereto.
