Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional calibration bracket is used, then the calibration function is achieved, but the volume is large and it is difficult to move
Solution Approach 1:
The calibration bracket employs a nested structure where the support assembly can be folded inward and stored within the stand assembly. The support rod can rotate and fold parallel to the stand rod, allowing the entire structure to compact into a much smaller volume for transportation while maintaining full functionality when deployed.
Solution Approach 2:
The calibration bracket transitions from a static, fixed structure to a dynamic, adjustable structure. The support assembly incorporates rotating joints and foldable mechanisms that allow it to change configuration between deployed and stored states, enabling easy movement and compact storage while maintaining calibration accuracy.
2Ease of manufacture
If a traditional calibration bracket is used, then the calibration function is achieved, but the assembly is complicated
Solution Approach 1:
The calibration bracket is divided into distinct modular components: a base assembly, a stand assembly with fixed and movable vertical rods, and a support assembly with foldable arms. Each module can be independently manufactured and assembled, simplifying the overall assembly process while reducing structural complexity through functional decomposition.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The compact design reduces the volume of the calibration bracket, making it easier to carry and assemble, while maintaining stability and accuracy for sensor calibration, thus improving the efficiency of ADAS calibration processes.
Implementation Method 1
a first threaded rotating member (260), a second threaded rotating member (262) and a threaded fixed member (264), the first threaded rotating member (260) being mounted to the fixed vertical rod (22) and being rotatable relative to the fixed vertical rod (22) only about the central axis
Implementation Method 2
the second threaded rotating member (262) having a first threaded structure (2628) and a second threaded structure (2629) spiraling about the central axis
