Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a solid tire operates at high speeds or under heavy load, then productivity and performance are improved, but the tire temperature increases leading to thermal degradation

Engineering Contradiction:
Improveoperational performanceVSAvoidtire temperature
Core Design Contradiction:
ProductivityVSTemperature

Solution Approach 1:

The temperature monitoring system performs preliminary detection of thermal conditions before thermal degradation occurs. By continuously monitoring tire temperature and comparing it against threshold values, the system enables preventive action (reducing speed or load) before the tire reaches dangerous temperature levels that would cause thermal degradation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback control by continuously measuring tire temperature, transmitting this data to a monitoring device, and providing alerts when temperature thresholds are exceeded. This closed-loop feedback enables real-time operational adjustments to prevent thermal degradation while maintaining productivity

Inventive Principle:
Principle #23Feedback

2Reliability

If the tire temperature is monitored continuously, then thermal degradation is prevented, but device complexity increases

Engineering Contradiction:
Improvetire durabilityVSAvoidmonitoring system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The monitoring system is segmented into separate functional modules: a temperature sensor embedded in the tire, a signal transmission component, and a remote monitoring device. This segmentation allows the complex monitoring function to be distributed, with minimal components in the tire itself and processing capabilities located remotely, thereby reducing in-tire complexity while maintaining reliability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses an intermediary transmission mechanism (such as a magnetically coupled transmitter or wireless communication interface) to bridge the temperature sensor and the remote monitoring device. This intermediary approach allows continuous temperature monitoring without requiring complex wiring or power systems within the tire, simplifying the overall device architecture

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

In accordance with presently disclosed embodiments, a tire monitoring system is provided. The tire monitoring system utilizes a heat sensor embedded in a solid rubber tire. The heat sensor detects a temperature of the solid tire, and a transmission system transmits signals indicative of the temperature from the heat sensor to a remote monitoring system. The remote monitoring system may monitor the temperature of the solid tire and output notifications to alert a user when preventive maintenance is needed. The heat sensor may be embedded in the solid rubber tire during the manufacture of the solid tire, or the heat sensor may be embedded into the solid tire after production of the tire is complete. The system may be used track cure time and temperature as the tire is being produced and/or to log tire performance information throughout the operation of the tire.
