Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional calibration bracket is used, then the calibration function is stable, but the volume is large and it occupies large area
Solution Approach 1:
The beam assembly 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 maintain its full calibration capability when assembled, while enabling compact folding for storage and transportation, thus reducing volume without compromising calibration stability.
Solution Approach 2:
The calibration bracket transitions from a static rigid structure to a dynamic foldable structure with pivotal connections between beam portions. The beam portions can rotate and fold around pivot points, allowing the bracket to change its configuration between a deployed state for calibration and a folded state for compact storage, effectively reducing occupied volume while maintaining functional stability.
2Reliability
If a traditional calibration bracket is used, then the calibration function is stable, but it is complicated to assemble and difficult to move
Solution Approach 1:
The bracket is segmented into modular components (stand assembly, beam assembly with multiple beam portions, connecting portions) that can be independently manufactured and assembled. The pivotal connections between beam portions allow for simple assembly through folding and locking mechanisms, reducing assembly complexity while maintaining calibration stability through precise positioning features.
Solution Approach 2:
The dynamic foldable design with pivotal connections enables the bracket to be easily collapsed into a compact configuration for transportation and storage. The assembly and disassembly processes are simplified by the folding mechanism, which allows single-person operation, while the locked folded state ensures stability during transport without compromising the calibration function when deployed.
3Stability of the object's composition
If the beam portions are fixed, then the structure is stable, but the volume cannot be reduced for transportation
Solution Approach 1:
The beam portions are connected through pivotal joints that allow rotation and folding, transforming the structure from a fixed rigid configuration to a dynamic foldable configuration. When deployed for calibration, the beam portions are locked into a stable fixed position ensuring structural integrity. When folded for transportation, the beam portions rotate around pivot points to reduce the overall volume, effectively reconciling stability requirements with transportation needs.
Solution Approach 2:
The beam assembly is segmented into multiple independently movable beam portions connected by pivotal joints. This segmentation allows each beam portion to be positioned and locked independently, maintaining structural stability during calibration while enabling compact folding for transportation. The modular segmented design provides both the rigidity needed for stable calibration and the flexibility needed for reduced transportation volume.

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 is supported by the stand assembly, and includes a beam, the beam being configured to mount a calibration element and including a left beam portion, a right beam portion and a connecting portion, the connecting portion being supported by the stand assembly, one end of the connecting portion being pivotally connected to the left beam portion, and the other end of the connecting portion being pivotally connected to the right beam portion. In the foregoing structure, the left beam portion and the right beam portion can respectively rotate toward each other relative to the connecting portion, to fold the beam assembly, so that a volume of the calibration bracket can be reduced to facilitate shipment.
