Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current calibration tools are used, then calibration function is provided, but mobility and ease of operation deteriorate due to bulky and stationary design
Solution Approach 1:
The calibration device is divided into multiple detachable frame components (base frame, standing frame, measurement frame, crossbar) that can be separated for transport and reassembled for use. This segmentation enables mobility while maintaining the complete calibration functionality when assembled.
Solution Approach 2:
The device incorporates adjustable components including pitch adjustment mechanisms and detachable couplings that allow the structure to be dynamically reconfigured. This enables the device to transition between compact transport state and expanded operational state, improving mobility without sacrificing calibration capability.
2Ease of operation
If calibration device is made portable and detachable, then ease of operation and mobility improve, but device complexity increases due to multiple components
Solution Approach 1:
Multiple frame components are designed to couple together through standardized interfaces, merging into a single functional calibration device when assembled. This reducing of multiple separate components into one integrated system during operation simplifies the user experience while maintaining portability benefits.
Solution Approach 2:
The frame components are designed with universal coupling mechanisms that allow them to be detached for storage and transport, then reassembled for calibration operations. The same components serve multiple purposes: structural support, positioning, and calibration target mounting, reducing the need for additional specialized parts.
