Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional calibration brackets are used, then the structure is simple, but the angle adjustment flexibility is insufficient
Solution Approach 1:
The calibration bracket transforms from a fixed structure to a dynamic adjustable structure by introducing an angle adjustment mechanism. The support rod can rotate relative to the base within a limited range (0-135 degrees), allowing the calibration element to be positioned at various angles to meet different calibration requirements while maintaining structural simplicity through controlled mobility.
Solution Approach 2:
The bracket is divided into separable functional modules: a base, a support rod with angle adjustment structure, and a hanger. This segmentation allows independent adjustment of each component, particularly the support rod's angle relative to the base, enabling flexible positioning without requiring complete structural redesign.
2Adaptability or versatility
If the angle adjustment range is increased to meet special calibration positions, then the calibration versatility improves, but the stability of the bracket may deteriorate
Solution Approach 1:
The bracket achieves both stability and versatility through controlled dynamics. The support rod is designed to rotate within a specific angle range (0-135 degrees) relative to the base, providing enough flexibility for various calibration positions while maintaining structural stability through defined movement limits and a locking mechanism that secures the rod at desired angles.
Solution Approach 2:
The invention changes the angular parameter of the support rod within an optimized range (0-135 degrees). This parameter adjustment allows the bracket to adapt to different calibration positions while avoiding excessive angles that would compromise structural stability. The limiting portion of the base enforces this parameter boundary to maintain stability.
3Measurement precision
If the angle adjustment structure is made more complex to achieve precise positioning, then the calibration precision improves, but the ease of operation deteriorates
Solution Approach 1:
The angle adjustment mechanism provides smooth rotational movement of the support rod relative to the base, allowing operators to easily adjust to precise calibration angles within the 0-135 degree range. The dynamic adjustment capability, combined with a locking mechanism, enables both ease of operation and positioning precision without requiring complex control systems.

AI summary
The present invention relates to the technical field of vehicle maintenance and repair as well as device calibration, and in particular, to a calibration bracket. The calibration bracket includes a base, a support rod and a hanger. The support rod is movably connected to the base. The hanger is mounted to the support rod. The base has an abutting face. The support rod includes a main rod and an angle adjustment structure. The main rod is connected to the angle adjustment structure. The angle adjustment structure is connected to the base. The angle adjustment structure is rotatable relative to the base. A range of angular rotation of the support rod is controlled by limiting positions in which the main rod of the support rod and the angle adjustment structure abut against the base. The support rod is rotatable within the range of angular rotation relative to the base. The hanger is mounted to the support rod and is configured to hang a calibration element on the support rod, thereby achieving flexible adjustment of a calibration angle of the calibration element.
