Wheel Fastener Pressure Sensing for Detachment Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent wear and tear of tires on commercial and heavy-duty vehicles lead to rapid stripping or damage of fastening structures, increasing the risk of wheel detachment due to improper fixation or rust, posing safety hazards.
Innovation Solution
A wheel detachment monitoring and detection device installed on vehicle wheels, comprising a washer, housing, detachment detection module, and power source, which detects the pressing force of the fastening member and sends a warning signal when the force is lost, ensuring real-time monitoring and prevention of unexpected detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the fastening structure (bolts and nuts) is repeatedly assembled and disassembled for tire replacement, then the tire can be regularly replaced on commercial vehicles, but the threads on the bolts and nuts get stripped or damaged faster, increasing the risk of wheel detachment
Solution Approach 1:
The device performs preliminary detection of fastening status before wheel detachment occurs. The detection module continuously monitors whether the fastening member is properly fastened, enabling early warning and prevention of wheel detachment incidents.
Solution Approach 2:
The system establishes a feedback loop by detecting the pressing force of the fastening member and sending warning signals when the force is lost or insufficient. This real-time feedback allows drivers to be alerted and take corrective action before wheel detachment occurs.
2Adaptability or versatility
If the fastening structure is exposed to weather conditions, then the bolts and nuts can be rusty and embrittled, but this leads to increased risk of wheel detachment
Solution Approach 1:
The detection device acts as an intermediary monitoring system between the fastening structure and the wheel. It continuously checks the fastening status and provides warning signals, serving as an additional safety layer that compensates for the inherent vulnerability of metal fastening components to weather-related degradation.
3Measurement precision
If no detection device is installed, then the structure remains simple, but accurate detection of correct fixation between tire and hub cannot be achieved
Solution Approach 1:
The patent extracts only the essential detection function needed for wheel detachment prevention. The detection module focuses specifically on monitoring the fastening member status and providing warning signals, eliminating unnecessary complex systems while achieving accurate detection of correct fixation.
4Reliability
If real-time monitoring is implemented, then wheel detachment can be prevented, but additional components (detection module, power source, housing) are required
Solution Approach 1:
The patent merges the detection module, power source, and housing into an integrated assembly that is installed on the wheel. This combined structure reduces the number of separate components and simplifies installation while maintaining real-time monitoring capability for wheel attachment safety.
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
The device accurately detects the proper fastening of vehicle wheels, preventing unexpected detachment and enhancing safety by providing real-time alerts to drivers, thus reducing the risk of accidents.
Implementation Method 1
the pressure sensing portion is pressed by the fastening member to press against a surface of the vehicle wheel and detects a pressing force acting thereon

AI summary
A wheel detachment monitoring and detection device is to be installed on a vehicle wheel. The wheel detachment monitoring and detection device includes a washer, a housing, a detachment detection module, and a power source. The washer defines a through hole for a fastening member to pass and fix the washer, and has an engaging portion partially covered by the fastening member. The housing gets engaged with the engaging portion and accommodates the detachment detection module. The detachment detection module has a pressure sensing portion that is pressed by the fastening member to press against the vehicle wheel, and detects a pressing force acting thereon. When the pressure sensing portion detects that the pressing force disappears, the detachment detection module sends out a warning signal. The wheel detachment monitoring and detection device ensures attachment of the vehicle wheel by monitoring looseness of the fastening member.
