Solution Overview
Problem
Existing surveillance cameras face challenges with multi-dimensional image-capturing direction adjustment due to increased rotational inertia and cable interference, particularly when using electrically adjustable designs with motors on movable parts, which affect stability and accuracy.
Innovation Solution
An adjustable seat mechanism with a transmission system that positions the driving module on an immovable part, using a mount, rotary base, rotary fixing frame, and fixing frame transmission mechanism to indirectly drive the image-capturing module, reducing cable interference and rotational inertia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a motor is installed on the movable part to achieve multi-dimensional adjustment of the image-capturing direction, then the camera can be remotely controlled to adjust the image-capturing direction, but the rotation or movement inertia of the movable part increases, making rotation or movement more difficult and stability difficult to maintain
Solution Approach 1:
Instead of placing the motor on the movable part (which increases inertia), the patent inverts the arrangement by placing the motor on the fixed support and using a transmission mechanism to drive the movable part. This allows remote control capability while avoiding the increased rotational inertia that would result from mounting the motor directly on the movable component.
Solution Approach 2:
The patent introduces a transmission mechanism as an intermediary between the motor (on the fixed support) and the movable part. This intermediary system transmits the driving force from the stationary motor to the movable component, enabling automated adjustment without requiring the motor to be mounted on the movable part itself, thus avoiding increased rotational inertia.
2Extent of automation
If a motor is installed on the movable part to achieve multi-dimensional adjustment, then the camera can be remotely controlled, but adjustment accuracy becomes difficult to improve
Solution Approach 1:
The patent inverts the conventional arrangement by placing the motor on the fixed support rather than on the movable part. This inversion allows the motor to remain stationary, providing stable automated control while avoiding the instability and reduced precision that would result from mounting the motor on the movable component.
Solution Approach 2:
A transmission mechanism serves as an intermediary between the stationary motor and the movable part, enabling precise force transmission. This intermediary system maintains adjustment accuracy by allowing the motor to operate from a stable, fixed position while still achieving precise control of the movable component's position and orientation.
3Extent of automation
If cables are connected to the motor on the movable part, then the motor can be powered and controlled, but the cables may interfere with the movement of the movable part or other movable parts
Solution Approach 1:
Instead of connecting cables to a motor on the movable part (which creates interference), the patent inverts the arrangement by placing the motor on the fixed support. This eliminates the need for cables to follow the movable part's motion, as the motor remains stationary and cables can be routed through fixed pathways without interfering with movement.
Solution Approach 2:
The transmission mechanism acts as an intermediary that decouples the motor from the movable part's motion path. By transmitting power and control signals through the stationary transmission system rather than through cables attached to the movable motor, the patent eliminates cable interference with the movement of the movable part and other components.
4Extent of automation
If cables are connected to the motor on the movable part, then the motor can be powered, but the cables increase restrictions on the layout of connection cables of other electronic components
Solution Approach 1:
The patent inverts the conventional cable routing approach by placing the motor on the fixed support rather than on the movable part. This inversion allows all cables to be connected to stationary components, dramatically simplifying cable layout and eliminating the complex routing restrictions that would arise from cables needing to accommodate the movable part's range of motion.
Solution Approach 2:
The transmission mechanism serves as an intermediary that consolidates cable connections at the stationary motor location. This intermediary arrangement allows all electrical connections to be made to fixed components, simplifying the overall cable layout and reducing the complexity restrictions that would result from having to route cables through or alongside movable components.
