Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional calibration bracket is used, then the calibration function is stable and reliable, but the volume is large and it is difficult to move
Solution Approach 1:
The calibration bracket employs a nested structure where the movable vertical rod is inserted into the fixed vertical rod, and the support assembly can be folded into the stand assembly. This nesting allows the bracket to be compacted to a small volume for easy transportation while maintaining full functionality when deployed.
Solution Approach 2:
The calibration bracket incorporates movable components including a movable vertical rod that can slide along the fixed vertical rod, and a support assembly that can be adjusted and folded. This dynamic design allows the bracket to transition between a compact transport state and an expanded operational state, resolving the contradiction between small volume and ease of movement.
2Ease of operation
If the calibration bracket is made compact for easy movement, then the ease of operation is improved, but the stability and accuracy may be compromised
Solution Approach 1:
The calibration bracket is divided into distinct modular segments including a base, fixed vertical rod, movable vertical rod, stand assembly, and support assembly. This segmentation allows each component to be optimized independently - the compact nested structure for portability and the extended configuration for stability during calibration operations.
Solution Approach 2:
The threaded rotating members automatically lock the movable vertical rod at selected positions through self-locking thread geometry, and the foldable support assembly automatically maintains its extended position during calibration through its structural design, providing inherent stability without additional active components.
3Volume of moving object
If a telescopic structure is used to reduce volume, then the ease of movement is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex motorized telescopic mechanisms with simple manual telescopic structures based on threaded rotating members and foldable joints. This mechanical substitution maintains the volume reduction benefit while significantly reducing device complexity and eliminating the need for power sources and control systems.

AI summary
The present invention relates to the field of vehicle calibration, and provides a calibration system and a calibration bracket therefor. The calibration bracket includes a base, a stand assembly and a support assembly. In the stand assembly, one end of a fixed vertical rod is mounted to the base; a movable vertical rod is mounted to an other end of the fixed vertical rod, the movable vertical rod being movable relative to the fixed vertical rod only along a central axis, and the support assembly being mounted to the movable vertical rod; and a driving mechanism includes a first threaded rotating member, a second threaded rotating member and a threaded fixed member. The first threaded rotating member is mounted to the fixed vertical rod and is rotatable relative to the fixed vertical rod only about the central axis. The second threaded rotating member has a first threaded structure and a second threaded structure spiraling about the central axis. A spiraling direction of the first threaded structure is the same as a spiraling direction of the second threaded structure. The second threaded rotating member is mounted to the first threaded rotating member through the first threaded structure and is mounted to the threaded fixed member through the second threaded structure. The threaded fixed member is fixedly mounted to the movable vertical rod.
