Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional calibration bracket is used, then calibration function is provided, but the bracket occupies large area and is difficult to move
Solution Approach 1:
The calibration bracket is divided into multiple beam portions (first beam portion, second beam portion, third beam portion) that can be pivotally connected and folded relative to each other. This segmentation allows the bracket to be collapsed into a compact configuration for easy movement and storage, while still providing the full calibration function when deployed.
Solution Approach 2:
The beam portions are connected through pivotal connections that enable dynamic folding and unfolding movements. The bracket transitions from a static, fixed-size structure to a dynamic, variable-size structure that can adapt its footprint based on operational needs, solving the contradiction between providing calibration function and occupying space.
2Measurement precision
If a stable calibration bracket is designed, then calibration precision is maintained, but the structure becomes complicated and difficult to assemble
Solution Approach 1:
The bracket is segmented into modular beam portions that can be independently manufactured and then assembled through pivotal connections. This modularity simplifies the manufacturing process for each component while maintaining the overall structural integrity and calibration precision when assembled.
Solution Approach 2:
The foldable beam portions can be nested or folded together when not in use, creating a compact configuration that is easy to store and transport. This nesting capability reduces the overall complexity of handling and assembling the bracket without compromising its stability during calibration operations.
3Volume of moving object
If the beam assembly is made foldable, then volume is reduced for shipment, but structural stability may be compromised
Solution Approach 1:
The pivotal connections between beam portions enable the bracket to dynamically transition between folded (low volume) and unfolded (stable operational) configurations. When unfolded for calibration, the structure forms a stable geometric arrangement that maintains structural integrity. When folded for shipment, the volume is minimized while the connections remain intact.
Solution Approach 2:
By dividing the beam assembly into separate pivotal segments, the design allows each segment to be compacted during transport while maintaining the ability to form a stable, rigid structure when deployed for calibration work.

AI summary
The present invention relates to the field of vehicle correction, and provides a calibration system and a calibration bracket thereof. The calibration bracket includes: a base, a stand assembly and a beam assembly. The stand assembly is fixedly connected to the base. The beam assembly includes a first beam portion, a second beam portion and a connecting portion, the connecting portion being mounted to the stand assembly, one end of the connecting portion being hinged to the first beam portion, and the other end of the connecting portion being hinged to the second beam portion. The first beam portion and the second beam portion can respectively rotate toward each other relative to the connecting portion, so that the beam assembly can be folded. The first beam portion and the second beam portion can also respectively rotate away from each other relative to the connecting portion, so that the beam assembly can be unfolded. In the foregoing structure, the first beam portion and the second beam portion can respectively rotate toward each other relative to the connecting portion, so that the beam assembly is folded, thereby reducing a volume of the calibration bracket to facilitate shipment.
