Solution Overview

Problem

Bicycle tires, especially green ones, lack structural consistency for proper handling by mechanical devices due to non-metallic bead cores and lack of reinforcement belt layers, leading to uncontrollable deformation and increased manual processing times for labeling and tread junction pressing.

Innovation Solution

A process and apparatus involving a support table with stretchers and labelling pads to stabilize and extend the tire, allowing simultaneous application of labels and pressing of the tread junction, reducing processing time and improving precision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If bicycle tires are made with non-metallic bead cores and without reinforcement belt layers to enable folding capability, then the tire becomes foldable and lighter, but the structural consistency deteriorates leading to uncontrollable deformation during handling

Engineering Contradiction:

Improvefolding capabilityVSAvoidstructural consistency

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent separates the labeling and pressing operations from the building process by introducing a dedicated support table system. This segmentation allows the tire to be handled in a controlled environment that compensates for its inherent structural weakness, enabling the folding capability to be maintained while addressing the deformation issue through process separation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support table acts as an intermediary device that provides stable positioning and extending for the tire during labeling operations. This intermediary structure compensates for the tire's lack of structural consistency, allowing accurate labeling without requiring the tire to maintain its own structural integrity during handling.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If manual pressing and labeling operations are performed on the building drum at room temperature, then the process is simple to implement, but the processing time increases and productivity decreases

Engineering Contradiction:

Improveprocess simplicityVSAvoidprocessing speed

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The tire is pre-positioned on the support table with proper extending and stabilization before the labeling operation begins. This preliminary setup allows the subsequent labeling and pressing operations to proceed efficiently without time-consuming adjustments during the actual labeling process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent combines multiple operations (labeling, pressing, and stabilizing) into a single integrated process on the support table. By merging these operations that were previously performed separately on the building drum, the process maintains simplicity while significantly reducing total processing time and improving productivity.

Inventive Principle:

Principle #5Merging (Combining)

3Manufacturing precision

If the tire is removed from the building drum for labeling operations, then the labeling can be performed on a stable surface, but the tire deformation becomes uncontrollable due to lack of support

Engineering Contradiction:

Improvelabeling accuracyVSAvoidtire deformation

Core Design Contradiction:

Manufacturing precisionVSShape

Solution Approach 1:

The support table serves multiple functions: it provides stable support for the tire, enables precise positioning for labeling, and maintains the tire's shape through its extending mechanism. This multi-functional device allows the tire to be removed from the building drum while preventing uncontrolled deformation, achieving both labeling accuracy and shape control.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Productivity

If labeling and pressing operations are performed simultaneously on the support table, then the cycle time is reduced and productivity increases, but the device complexity increases

Engineering Contradiction:

Improvecycle timeVSAvoidapparatus structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The support table incorporates movable stretchers and positioning mechanisms that can dynamically adjust during the labeling process. This dynamic capability allows the system to accommodate the tire's shape changes and positioning requirements while enabling simultaneous labeling and pressing operations, achieving improved productivity without excessive complexity.

Inventive Principle:

Principle #15Dynamics
