Roller Brake Tester Alignment for ADAS and Brake Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller brake testers for vehicle brake systems are used sub-optimally, requiring separate devices for brake and driving assistance system testing, occupying excessive space, and necessitating frequent maintenance.
Innovation Solution
A device with aligning means that positions vehicles on rollers at a predetermined location, allowing simultaneous testing of brake and driving assistance systems, using a single platform with integrated aligning rollers and measuring devices to measure forces on the rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single roller brake tester is used for brake system testing, then the device occupies less space and requires less maintenance, but the vehicle position on the rollers is uncontrolled and driving assistance systems cannot be tested
Solution Approach 1:
The roller brake tester is designed to perform multiple functions: both brake system testing and driving assistance system testing. The device achieves this by integrating an aligning means that can position vehicles at specific locations on the rollers, enabling the same device to support both traditional brake tests and advanced driving assistance system tests that require precise vehicle positioning.
2Reliability
If separate devices are used for brake testing and driving assistance system testing, then each device can be optimized for its specific function, but the device occupies more space and requires more intensive maintenance
Solution Approach 1:
The patent combines brake system testing functionality and driving assistance system testing functionality into a single roller brake tester device. By integrating an aligning means that can position vehicles at predetermined locations, the device merges what would traditionally require separate testing equipment, thereby reducing the number of devices needed while maintaining both testing capabilities.
3Productivity
If the vehicle position on the rollers is not controlled, then the device is simpler to operate, but the throughput time in production environment is longer due to repeated positioning
Solution Approach 1:
The aligning means performs preliminary positioning of the vehicle on the rollers before the actual testing begins. By pre-positioning the vehicle at a predetermined location during the alignment phase, the system eliminates the need for repeated positioning adjustments during subsequent testing operations, thereby improving throughput time in production environments while maintaining operational simplicity.
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
Facilitates efficient, space-saving, and low-maintenance testing of both brake and driving assistance systems, reducing the need for multiple devices and shortening production throughput time.
Implementation Method 1
The aligning roller is rotatable relative to the aligning means and functions as rotating stop surface during rotation of the set of rollers. Not only is friction between the aligning means and the adjacent wheel considerably reduced, displacement of the vehicle on the set of rollers is also simplified.
Implementation Method 2
each roller of the plurality of rollers is provided with a drive with a measuring device which is configured to measure a force exerted on the roller
