Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile phone APP software is used to control the gimbal, then control functionality is provided, but operation convenience deteriorates and control precision is reduced
Solution Approach 1:
The patent replaces the mechanical mobile phone APP control system with an electronic sensor-based system. The dial assembly uses a sensor to detect rotation angles and convert them into control signals, eliminating the need for complex software interfaces and improving both operation convenience and control precision through direct electronic signal transmission.
Solution Approach 2:
The patent introduces a sensor as an intermediary between the dial assembly and the control system. The sensor acts as a mediator that converts physical rotation into electrical signals, providing a more direct and precise control pathway compared to mobile phone APP software, thereby improving both ease of operation and control precision.
2Reliability
If mobile phone APP software is used for control, then control functionality is achieved, but reliability deteriorates when phone is unavailable or signal is interrupted
Solution Approach 1:
The patent extracts the control functionality from the mobile phone system and integrates it directly into the remote control device. By removing the dependency on external phone systems and signal connections, the invention achieves reliable control operations while maintaining manageable system complexity through self-contained control circuitry.
Solution Approach 2:
The remote control device becomes self-sufficient by incorporating its own sensor and control signal generation capabilities. The system serves itself by generating control signals internally through the sensor without requiring external phone systems, thereby improving reliability while keeping the device structure manageable.
3Ease of operation
If both remote control and mobile phone are used for control, then control functionality is provided, but operation convenience deteriorates
Solution Approach 1:
The patent merges the gimbal control functionality with the main remote control device by integrating a sensor directly into the dial assembly. This consolidation eliminates the need to use separate mobile phone APP controls, improving operation convenience while managing system complexity through integrated design.
Solution Approach 2:
The remote control device is designed with multi-functionality, incorporating both general UAV control and specific gimbal control capabilities through the integrated sensor system. This universal design allows a single device to perform multiple control functions, improving ease of operation while maintaining reasonable system complexity.
