Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed mounting structure is used for the calibration element, then the structure is simple and stable, but the calibration element cannot be adjusted to different angles relative to the sensor
Solution Approach 1:
The patent applies the dynamics principle by introducing a rotating component that enables the stand component to pivot relative to the base about a central axis. This dynamic mechanism allows the cross beam component to adjust its rotational angle freely, transforming a static fixed mounting structure into an adjustable dynamic system that can accommodate different sensor positions and configurations.
Solution Approach 2:
The patent segments the calibration bracket into distinct functional components: a base, a rotating component, a stand component, and a cross beam component. This segmentation allows each component to perform its specific function independently while maintaining overall system simplicity. The rotating component is further divided into a support seat, rotating base, and stand base, enabling precise angular adjustment without complicating the entire structure.
2Adaptability or versatility
If the calibration element is mounted at a fixed position on the calibration bracket, then the manufacturing is simple, but it cannot accommodate different sensor mounting positions on the vehicle
Solution Approach 1:
The rotating component with pivotable stand component enables the calibration bracket to adapt to different sensor mounting positions through angular adjustment, maintaining manufacturing simplicity by using a modular design that requires no custom manufacturing for each sensor position.
Solution Approach 2:
The calibration bracket is designed as a universal device that can accommodate various sensor positions and configurations through its rotating and pivoting mechanisms. The cross beam component can be mounted at different heights and angles, making the same bracket suitable for calibrating sensors at different locations on different vehicles.
3Measurement precision
If multiple adjustment mechanisms are added to achieve precise angular adjustment, then the calibration precision is improved, but the device complexity increases
Solution Approach 1:
The patent achieves precise angular adjustment with a single rotating component that allows the stand component to pivot about a central axis. This dynamic mechanism provides continuous angular adjustability without requiring multiple discrete adjustment mechanisms, maintaining calibration precision while avoiding excessive complexity.
Solution Approach 2:
The patent merges the functions of multiple potential adjustment mechanisms into a single integrated rotating component. The support seat, rotating base, and stand base work together as one unified mechanism, combining rotational and pivoting functions that would otherwise require separate adjustment devices.

AI summary
A calibration bracket (100), comprising: a base (10); a stand component (20) connected to the base (10); a cross beam component (30, 30') mounted to the stand component (20) and used for mounting a calibration element, which is used for calibrating an advanced driver assistant system of a vehicle; and a rotating component (40) mounted between the stand component (20) and the base (10), and used for driving the stand component (20) to pivot about a central axis of the stand component (20) relative to the base (10) so as to adjust an angle of rotation of the cross beam component (30, 30) relative to the central axis of the stand component (20). According to the structure, an angle of rotation of the cross beam component (30, 30') relative to the central axis of the stand component (20) can be adjusted, so that the rotation of the cross beam component (30, 30') is free from the mounting position. The calibration bracket is simple in structure, and convenient to carry.
