Integrated TPMS Hose Layout for Secure Sensor Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic tire inflation systems face issues with TPMS sensor theft and misplacement due to their conventional mounting on inspection valves, which also complicates manual tire pressure checks.
Innovation Solution
A TPMS-sensor-integrated automatic tire inflation system hose with a defined orientation, featuring a first valve for tire mounting, a second valve for rotary housing, a resin hose, an inspection valve, and a TPMS sensor in fluid communication, ensuring consistent wireless transmission and preventing sensor loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the TPMS sensor is mounted to the inspection valve, then the sensor can be easily accessed and installed, but the sensor becomes vulnerable to theft and misplacement, and manual tire pressure checks are complicated
Solution Approach 1:
The patent integrates the TPMS sensor directly into the automatic tire inflation system hose, merging the sensor mounting location with the hose structure itself. This eliminates the separate inspection valve mounting approach, securing the sensor to a fixed position on the hose that cannot be easily removed or stolen, while still allowing access for both automatic inflation operations and manual pressure checks.
2Ease of manufacture
If the TPMS sensor is mounted to the inspection valve, then the sensor can be installed, but the sensor orientation becomes undefined, disrupting wireless communication
Solution Approach 1:
The patent incorporates the TPMS sensor into the hose during the manufacturing process, performing the orientation positioning action in advance. The sensor is pre-oriented to face the correct direction (away from the trailer in the axle direction) during hose fabrication, ensuring consistent wireless transmission orientation before the hose is ever installed on the vehicle. This eliminates orientation problems that would occur with field installation.
3Ease of operation
If the TPMS sensor is mounted to the inspection valve, then the sensor can be accessed, but the sensor must be removed for manual pressure checks, leading to loss or misplacement
Solution Approach 1:
The patent combines the TPMS sensor mounting location with the hose structure itself, creating a unified system where the sensor is an integral part of the inflation system. This merging eliminates the need to remove the sensor for manual pressure checks, as the inspection valve remains accessible on the hose while the sensor stays securely mounted, preventing loss or misplacement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures reliable tire pressure monitoring by maintaining optimal TPMS sensor orientation and preventing theft or misplacement, allowing seamless manual pressure checks without disrupting wireless communication.
Implementation Method 1
Each TPMS sensor is configured to sense tire pressure and wirelessly transmit the sensed tire pressure to a receiver
Implementation Method 2
Pressurized and regulated gas is thus provided to each tire through the automatic tire inflation system hose
