Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a damping mechanism is used to stabilize camera equipment during movement, then footage stability is improved, but the system becomes more complex and sensitive to road conditions
Solution Approach 1:
The damping mechanism is divided into independent modular components: mounting frame, mounting piece, balancing assembly with actuators, and sensing units. Each module performs a specific function and can be independently adjusted or replaced, reducing overall system complexity while maintaining stabilization effectiveness.
Solution Approach 2:
The system employs dynamic adjustment capabilities where actuators actively modify the mounting piece position in real-time based on sensing unit feedback. This dynamic response allows the mechanism to adapt to varying road conditions without requiring an overly complex fixed-configuration system.
2Reliability
If actuators and sensing units are added to detect and counteract deflection, then lens stability is improved, but device complexity and energy consumption increase
Solution Approach 1:
The sensing units detect mounting piece deflection in real-time and provide feedback to the actuators, which automatically adjust to counteract the detected movement. This closed-loop feedback system ensures reliable lens stabilization while using standard off-the-shelf components to manage complexity.
Solution Approach 2:
The balancing assembly is designed to automatically correct mounting piece deflection without requiring external intervention. The sensing units and actuators work together in an autonomous manner to maintain lens stability, reducing the need for complex manual adjustment mechanisms.
3Stability of the object's composition
If damping forces are dynamically adjusted based on deflection angle, then footage smoothness is improved, but energy consumption increases
Solution Approach 1:
The actuators apply damping forces in periodic pulses rather than continuous operation, activating only when the sensing units detect deflection events. This periodic action pattern maintains footage smoothness while significantly reducing overall energy consumption compared to continuous damping application.

Function Achieved in This Case
The system effectively reduces jitter and enhances the stability of camera equipment during movement by dynamically adjusting damping forces based on detected deflection, ensuring smooth and stable footage.
Implementation Method 1
The sensing unit is designed to detect movement of the mounting piece and transmit this information to the actuator, enabling the actuator to provide varying damping forces based on the deflection angle of the mounting piece.
Implementation Method 2

AI summary
A damping head, including a mounting frame; a mounting piece, movably connected to the front end of the mounting frame; and a balancing assembly, including a sensing unit, multiple actuators, and multiple transmission links. Two actuators are positioned on either side of the mounting frame, with each actuator connected to a corresponding transmission link. One end of each transmission link is connected to the actuator, and the other end is connected to the mounting piece. The sensing unit is designed to detect movement of the mounting piece and transmit this information to the actuator. When a vehicle is in motion and the shooting device experiences jitter, the mounting piece deflects. The sensing unit detects this deviation and transmits it to the actuator, which then drives the transmission link to provide a counteracting damping force to the mounting piece according to the deflection angle, ensuring the stability of the shooting device.
