Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional sideslip tester is used, then the measurement process can be completed, but the measurement results vary due to worker subjectivity and cannot replicate actual driving conditions
Solution Approach 1:
The patent replaces the traditional mechanical measurement system with an optical sensing system. A laser distance sensor mounted on a support beam measures the distance to the vehicle's lateral surface, converting mechanical measurement into optical measurement. This eliminates worker subjectivity and enables consistent, objective measurement of sideslip under actual driving conditions.
Solution Approach 2:
The patent introduces a laser distance sensor as an intermediary between the measurement system and the vehicle. The sensor mounted on the support beam acts as a mediator that objectively captures distance variations without human intervention, transforming the measurement process from subjective mechanical assessment to objective optical detection.
2Device complexity
If manual measurement methods are used, then the measurement process is simple, but a reliable database of sideslip data cannot be created
Solution Approach 1:
The patent enables continuous measurement of sideslip data as the vehicle passes through the testing area. The laser distance sensor continuously records distance variations, creating a continuous data stream that can be stored in a database. This continuous measurement capability transforms discrete manual measurements into a comprehensive data set for analysis and comparison.
Solution Approach 2:
The patent creates a digital copy of the physical measurement process. The laser distance sensor captures and records distance data, creating a digital representation of sideslip that can be stored, analyzed, and compared. This digital copying enables database creation without adding significant physical complexity to the measurement system.
3Measurement precision
If objective measurement is implemented using laser distance sensor, then consistent sideslip measurement is achieved, but the device complexity increases
Solution Approach 1:
The patent divides the measurement system into separate functional components: a support beam structure for mounting, a laser distance sensor for measurement, and a display device for data presentation. This segmentation allows each component to be optimized independently and simplifies the overall system architecture, reducing complexity while maintaining measurement objectivity.

AI summary
A sideslip test for a vehicle that can make a database of sideslip and objectively measure the sideslip. A sideslip test system may include: a driving road provided to drive a vehicle; a support beam disposed to be supported on the driving road; a distance sensor mounted on the support beam to measure a distance from the vehicle; and a display device connected with the distance sensor and visualizing a measurement value of the distance sensor. A sideslip test method may include: entering, by the vehicle, the driving road; sensing a distance between the distance sensor and the vehicle; converting data to express the distance sensed by the distance sensor as a coordinate; collecting a closest Y-axis distance between the distance sensor and the vehicle as a representative value; and expressing a distribution of the representative value as a graph through the display device.
