Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a tire pressure monitoring system is used to monitor tire pressure, then tire pressure can be collected and monitored, but the system cannot actively manage tire pressure and requires manual inflation or deflation with external tools

Engineering Contradiction:

Improvetire pressure management capabilityVSAvoidmanual operation requirement

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The tire pressure management system performs self-service by automatically controlling inflation and deflation operations through the wireless control switch valve. The system monitors tire pressure and autonomously executes pressure adjustment without requiring external tools or manual intervention, transforming the monitoring system into an active self-managing system.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operations with an automated electronic control system. The wireless control switch valve eliminates the need for physical connection and manual operation of traditional valve systems, using wireless communication and electronic control to achieve automatic tire pressure management.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Extent of automation

If a traditional valve system is used for tire inflation and deflation, then external tools can manually adjust tire pressure, but the system lacks automation and requires continuous manual intervention

Engineering Contradiction:

Improveautomatic tire pressure controlVSAvoidsystem structure

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The wireless control switch valve serves multiple functions: it acts as a wireless communication receiver, a control valve for inflation/deflation, and an integrated control unit. By combining these functions into a single component, the system achieves high automation without proportionally increasing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The wireless control switch valve serves as an intermediary between the controller and the tire air chamber. It receives wireless control signals and translates them into physical valve actions, mediating between the electronic control system and the pneumatic system, thereby enabling automated control while simplifying the interface between different subsystems.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

This application discloses a tire pressure regulating system and method, and a vehicle. A wireless control switch valve of the tire pressure regulating system is configured to control opening and closing of a tire air chamber of a vehicle tire. A controller controls, through a wireless communication module, the wireless control switch valve to open the tire air chamber after determining that a vehicle meets a preset inflation or deflation condition, and controls, through the wireless communication module, the wireless control switch valve to close the tire air chamber after an inflation or deflation operation on the tire air chamber is completed.
