Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current devices and techniques are used to determine the center of gravity, then the process can be completed, but the measurement precision is insufficient and the time required is excessive
Solution Approach 1:
The patent replaces traditional mechanical CG determination methods with a digital sensor-based system. Digital CG sensors electronically measure the position and calculate the center of gravity, substituting manual mechanical procedures with automated electronic measurement and computation, thereby achieving both higher precision and faster results
Solution Approach 2:
The system performs self-measurement and self-calculation of the center of gravity. The digital sensors automatically detect the aircraft's weight distribution, and the integrated processor computes the CG location without requiring external intervention or complex manual procedures, enabling rapid and precise determination
2Measurement precision
If traditional CG determination methods are used, then the process is simple to operate, but the measurement precision is insufficient
Solution Approach 1:
The base member serves multiple functions: it provides structural support, houses the slotted track for sensor positioning, and acts as the reference platform for measurement. This multi-functionality reduces the need for separate components, maintaining relative simplicity while achieving precise digital measurement capabilities
Solution Approach 2:
The measurement system is segmented into modular components: the base member with slotted track, multiple digital CG sensors positioned at different locations, and a processing system. This segmentation allows each component to be optimized independently while working together to achieve high precision CG determination
3Productivity
If manual CG determination techniques are used, then the device complexity is low, but the productivity is insufficient
Solution Approach 1:
The patent replaces manual mechanical CG determination with an automated digital system. Digital sensors electronically capture weight distribution data, and a processor automatically calculates the center of gravity position, eliminating time-consuming manual procedures and significantly improving measurement efficiency
Solution Approach 2:
The system provides immediate feedback by automatically processing sensor data and calculating the center of gravity location in real-time. This instant feedback mechanism eliminates waiting periods associated with manual methods, thereby increasing productivity without requiring complex iterative adjustments

AI summary
A device for determining the center of gravity (CG) of a remote controlled aircraft includes a base member having a slotted track defined therein and a plurality of support platforms mounted on the base member. Each support platform of the plurality of support platforms is slidably positionable along the slotted track and each support platform may receive a digital CG sensor thereon. A plurality of leveling members is also mounted on the base member, with each leveling member of the plurality of leveling members being independently vertically translatable to adjust the orientation of the base member until the base member is level with the horizontal plane.
