Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual sensor installation methods are used, then installation flexibility is maintained, but installation efficiency and adhesion consistency deteriorate

Engineering Contradiction:

Solution Approach 1:

The system uses robotic automation to perform deglazing, adhesive application, and sensor placement operations that would otherwise require manual intervention. The robot autonomously navigates the tire interior, positions the sensor, and applies adhesive with consistent precision, eliminating manual labor while maintaining process control through automated feedback mechanisms.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operations with a robotic system that integrates laser deglazing, automated adhesive dispensing, and precision sensor placement. The robotic arm substitutes human hands for all critical installation steps, while integrated sensors and controllers replace manual inspection and positioning methods.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If standardized automated installation process is implemented, then adhesion consistency improves, but installation process complexity increases

Engineering Contradiction:

Solution Approach 1:

The robotic system performs deglazing of the tire inner surface before adhesive application, creating an optimized surface for maximum adhesion. The system also pre-mixes and pre-heats adhesive materials to specific temperatures and viscosities, ensuring consistent bonding conditions before the actual sensor attachment occurs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent controls critical parameters including adhesive temperature, viscosity, application rate, and curing conditions through automated systems. The robotic arm adjusts positioning precision, force application, and exposure time to optimized values, while environmental controls maintain temperature and humidity within specified ranges for consistent adhesion results.

Inventive Principle:

3Manufacturing precision

If laser deglazing is used, then surface preparation quality improves, but energy consumption increases

Engineering Contradiction:
Improvesurface preparation qualityVSAvoidlaser energy consumption
Core Design Contradiction:
Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The laser system applies energy selectively only to the specific areas of the tire inner surface that require deglazing, rather than treating the entire surface uniformly. The robotic arm positions the laser to focus on localized zones around the sensor installation site, concentrating energy where needed and minimizing overall power consumption.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The laser operates in pulsed or intermittent mode rather than continuous operation, activating only when the robotic arm positions it over the target surface area. This periodic activation reduces total energy consumption while maintaining effective deglazing quality through high-intensity brief pulses that achieve surface preparation in short time intervals.

Inventive Principle:
Principle #19Periodic action
