Floating Tire Pressure Detector Balances Wheel Mass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire pressure detection systems, especially the direct type, face issues with uneven wheel mass distribution and vibration due to the weight of detection devices, requiring complex installation and potential damage during air filling, and indirect systems fail to provide actual pressure values, while also affecting wheel balance.
Innovation Solution
A tire pressure detector with a movable main body placed in the pressure space between the tire and rim, equipped with a detection module that includes a sensing unit, central processing unit, and wireless transmission unit, allowing for dynamic balancing and wireless pressure signal transmission, eliminating the need for fixed installation and balancing the wheel mass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a direct type detection device is fastened on the air tap, then actual tire pressure value can be provided, but the mass of the wheel becomes unevenly distributed affecting wheel balance
Solution Approach 1:
The detection device is extracted from the external air tap mounting location and relocated to float freely within the tire's air space. This removes the source of mass imbalance from the wheel's external structure while preserving the pressure detection function through the breathing tube connection to the tire's internal pressure environment.
Solution Approach 2:
A breathing tube serves as an intermediary element, connecting the detection device to the tire's pressure space without requiring direct attachment to the wheel's external structure. The tube transmits pressure information while allowing the detector to float freely, thus decoupling the detection function from the wheel's mass distribution.
2Ease of manufacture
If an external type detection device is disposed at the air tap, then manual installation is simple, but the detection device must be disassembled during air filling posing damage risk
Solution Approach 1:
The detection device is extracted from the air tap interface and placed inside the tire's air space. This eliminates the need for repeated assembly and disassembly during air filling operations, as the device remains permanently installed within the tire while still accessing pressure data through the breathing tube.
Solution Approach 2:
The breathing tube is pre-installed on the air tap before the detection device is placed in the tire. This preliminary setup allows the detector to be permanently positioned inside the tire without requiring future disassembly during air filling, as the tube maintains the pressure connection independently.
3Measurement precision
If a detection device with certain weight is fastened on the air tap, then tire pressure can be detected, but wheel balance is affected requiring rebalancing
Solution Approach 1:
The detection device is extracted from the external air tap mounting position and relocated to float within the tire's internal air space. This removes the imbalance-causing mass from the wheel's external structure, eliminating the need for rebalancing operations while maintaining pressure detection through the internal breathing tube connection.
Solution Approach 2:
The detection device is designed to float freely within the tire's air space rather than being fixed to a specific location. This dynamic positioning allows the device to move with the tire's rotation without creating static imbalance, as its weight is distributed throughout the air space rather than concentrated at a single external mounting point.

AI summary
A tire pressure detector (100) disposed at a wheel (1), wherein the wheel (1) includes a rim (2) and a tire (3) mounted around the rim (2), with a pressure space (8) formed between the tire (3) and the rim (2). The rim (2) includes an air tap (9) connected with the pressure space (8). The tire pressure detector (100) includes a main body (10) movably disposed in the pressure space (8) and provided with a housing space (11), and a detection module (20) disposed in the housing space (11). The detection module (20) further includes a sensing unit (21) for sensing the air pressure in the pressure space (8) and producing a pressure signal. A central processing unit (23) of the detection module (20) receives the pressure signal and wirelessly transmits the pressure signal through the wireless transmission unit (24). Therefore, vibration and waving issue due to imbalance weight is avoided, thus balancing the wheel (1).
