Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used to control lens motors, then system reliability is improved, but flexibility and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The remote controller transmits control signals wirelessly to the lens control system, eliminating the need for physical wired connections between the operator and the camera rig. This substitution maintains control reliability through wireless protocol implementation while dramatically improving system flexibility and ease of operation by allowing free movement without cable constraints.
2Stability of the object's composition
If wired connections are used for lens control, then connection stability is improved, but adaptability deteriorates
Solution Approach 1:
The wireless communication system replaces the fixed mechanical connection structure, enabling the camera rig to be adapted to various shooting positions and configurations. The wireless control allows the system to work in environments where wired connections would be impractical, such as when the camera is mounted on moving vehicles or positioned in hard-to-reach locations, thereby significantly improving system adaptability while maintaining connection stability through reliable wireless communication protocols.
3Ease of manufacture
If traditional lens control motors are used, then manufacturing simplicity is improved, but measurement precision deteriorates
Solution Approach 1:
The patent incorporates feedback mechanisms in the lens control motors that provide real-time information about motor position and rotation status to the control system. This feedback enables precise control and measurement of motor rotation, allowing the system to achieve high measurement precision while maintaining relatively simple motor manufacturing. The feedback loop allows for continuous adjustment and correction, ensuring accurate lens positioning without requiring extremely complex motor designs.
