Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional gimbal design is used without interactive design for time-lapse photography, then the basic gimbal function is maintained, but the ease of operation for time-lapse photography deteriorates
Solution Approach 1:
The system pre-generates motion trajectory data and attitude information for time-lapse photography before actual shooting. Users can set trajectory points and the system automatically calculates the motion path and attitude changes needed, eliminating the need for manual real-time adjustment during shooting and making time-lapse photography easier to operate.
Solution Approach 2:
The patent introduces a control device as an intermediary between the user and the gimbal system. This control device handles the complex trajectory calculation, attitude adjustment, and coordinate transformation, acting as a mediator that simplifies the user interface while managing the underlying complexity of the gimbal's motion control system.
2Productivity
If manual attitude adjustment is required for each trajectory point, then precision can be maintained, but the time required for operation increases
Solution Approach 1:
The system automatically calculates motion trajectories and adjusts attitudes based on pre-set trajectory points. The control device autonomously performs coordinate transformations, computes motion paths, and generates control commands without requiring manual intervention for each adjustment, enabling the system to serve itself and dramatically improving photography efficiency.
Solution Approach 2:
The patent replaces manual mechanical adjustment operations with automated computational systems. Instead of manually adjusting the gimbal for each trajectory point, the system uses algorithms to calculate trajectories and automatically generates control commands, substituting mechanical manual operations with automated electronic control.
3Ease of operation
If automated trajectory generation is implemented, then ease of operation improves, but measurement precision of attitude information may deteriorate
Solution Approach 1:
The system incorporates feedback mechanisms where the control device receives actual gimbal attitude data and compares it with the planned trajectory. This feedback loop allows the system to detect deviations and make real-time corrections, ensuring that automated trajectory generation maintains high measurement precision while keeping operation simple.
Solution Approach 2:
The system performs preliminary calculation of precise motion trajectories and attitude information before shooting begins. By pre-computing the exact path and attitude changes needed, the system ensures measurement precision is maintained in the automated setup, allowing users to simply confirm or adjust the pre-calculated parameters without sacrificing accuracy.

AI summary
A motion trajectory determination method includes obtaining at least one trajectory point of a gimbal that includes attitude information, obtaining, in response to receiving a trajectory point adjustment command, an actual attitude of the gimbal and adjusting the attitude information of a trajectory point to be adjusted according to the actual attitude, and determining a motion trajectory of the gimbal according to all of trajectory points of the gimbal.
