Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual tire pressure monitoring in vehicles is complex and often not performed regularly, leading to increased risks due to incorrect pressures, and existing sensor-based systems face challenges with automated assignment between tire pressure sensors and wheel positions, resulting in potential errors and increased maintenance costs.
Innovation Solution
A tire pressure monitoring system that includes pressure sensors installed on or in the wheel, rim, or valve, which record internal tire pressure and send communication signals containing tire pressure and rotary angle indications, enabling automated assignment and reducing human error through wireless communication standards like Bluetooth or Zigbee.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual tire pressure monitoring is performed, then the system complexity is low, but the reliability of tire pressure monitoring decreases due to human error and irregular checks
Solution Approach 1:
The tire pressure monitoring system performs automatic measurements and transmissions without requiring user intervention. The sensor autonomously monitors tire pressure, determines wheel position based on rotation angle, and transmits data to the control unit, eliminating human error while maintaining simple operation for the user.
Solution Approach 2:
The patent replaces manual mechanical monitoring with an automated sensor-based system that uses electronic sensing and wireless communication. The control unit automatically processes sensor data and assigns wheel positions based on rotation angle information, substituting human operations with automated electronic systems.
2Reliability
If sensor-based tire pressure monitoring is implemented, then the reliability of tire pressure detection improves, but the device complexity increases due to manual sensor-to-wheel-position assignment
Solution Approach 1:
The sensor transmits not only tire pressure data but also rotation angle information to the control unit. The control unit uses this feedback to automatically determine wheel position based on the rotation angle, eliminating the need for manual assignment and reducing system complexity while maintaining high accuracy.
Solution Approach 2:
The tire pressure sensor is designed to perform multiple functions: measuring tire pressure, determining wheel position through rotation angle detection, and transmitting both types of information. This multi-functionality eliminates the need for separate assignment procedures, reducing complexity while maintaining accuracy.
3Productivity
If manual wheel position assignment to sensors is performed, then the device complexity is low, but the productivity decreases due to time-consuming maintenance procedures
Solution Approach 1:
The sensor continuously provides rotation angle information that enables the control unit to pre-determine wheel position assignments. This preliminary automated assignment is ready before maintenance is needed, eliminating time-consuming manual procedures and improving maintenance efficiency while requiring automated processing capabilities.
4Productivity
If automated sensor-based monitoring is used, then the productivity of tire pressure monitoring improves, but the device complexity increases due to communication systems and automated assignment algorithms
Solution Approach 1:
The patent combines the tire pressure sensing function with rotation angle detection and wireless communication capabilities into an integrated sensor system. The control unit merges data processing, wheel position determination, and communication management into a single automated system, improving productivity while consolidating complexity into unified modules.
