Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cold weather, it is difficult for vehicle drivers to determine if the wheels are locked due to air brake malfunction, leading to potential costly repairs as existing methods lack effective indicators for wheel rotation status, especially at night.
Innovation Solution
A wheel lock indicator kit featuring elongated bars with magnetized ends for secure attachment to wheels and integrated light assemblies with switches and reflective tapes to indicate wheel rotation status, allowing drivers to detect locked wheels through visible light cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If no indicator is installed on the wheel, then the device complexity is low, but the driver cannot detect wheel locking status especially at night
Solution Approach 1:
The patent replaces complex mechanical indicators with a simple optical system. A light source (LED or similar) is positioned to illuminate the wheel rim or a specific feature on the wheel, allowing the driver to visually detect wheel rotation status through reflected light patterns. This substitution of mechanical detection with optical detection reduces device complexity while improving information availability about wheel locking status.
Solution Approach 2:
The patent utilizes color or light intensity changes to indicate wheel locking status. The indicator may use different colors (e.g., green for rotating, red for locked) or varying light intensities to communicate the wheel's operational state to the driver. This visual signaling method provides clear, immediate information about wheel status without requiring complex mechanical or electronic systems.
2Difficulty of detecting and measuring
If a complex indicator system is installed to detect wheel locking, then the detection capability is improved, but the ease of operation and installation becomes difficult
Solution Approach 1:
The patent employs a self-service indicator system that automatically detects and displays wheel locking status without requiring driver intervention or complex calibration. The indicator may use the wheel's own rotation to generate the detection signal (e.g., through a magnetic sensor detecting passing magnets on the rim) or simply rely on visual observation of illuminated features on the rotating wheel. This self-operating approach simplifies both installation and operation while maintaining effective detection capability.
3Loss of information
If visual indicators are added to indicate wheel status, then the information visibility is improved, but the weight of the indicator device increases
Solution Approach 1:
The patent employs lightweight, inexpensive optical components such as LEDs, reflective tapes, or simple illuminated markers that can be easily attached to the wheel. These components provide effective visual indication of wheel status while adding minimal weight. The use of energy-efficient LEDs and passive reflective elements ensures that the weight addition is negligible compared to the benefit of improved information visibility for the driver.
