Surveillance Camera Tension Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surveillance cameras face challenges in accurately adjusting the rotation angle of the lens due to declining belt tension caused by temperature changes, poor assembly, or long-term usage, leading to cumbersome re-adjustment processes.
Innovation Solution
A tension adjustment mechanism featuring a base, positioning component, and actuating components with an inclined guiding structure, allowing for easy and rapid adjustment of belt tension by sliding the positioning component relative to the base, using a movable fixing component to deform and adjust the motor's position, thereby controlling belt tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the motor pulls the belt to rotate the turntable and adjust the lens rotation direction, then the lens rotation angle can be adjusted, but the belt tension may decline due to temperature changes, poor assembly or long-term usage, causing inaccurate adjustment
Solution Approach 1:
The patent introduces a dynamic tension adjustment mechanism where the positioning component can slide along the base and the fixing component can adjust its position to change belt tension. This allows the system to adapt to tension changes over time, maintaining reliable belt tension and ensuring accurate lens rotation angle adjustment despite temperature variations, assembly variations, or long-term usage.
Solution Approach 2:
The patent enables parameter changes in belt tension through the movable positioning component and fixing component. By adjusting the position of these components, the belt tension can be dynamically modified to compensate for degradation over time, ensuring consistent operation and accurate lens adjustment.
2Reliability
If the installation position or angle of the belt is readjusted to change the tension, then the belt tension can be modified, but the operation becomes cumbersome
Solution Approach 1:
The patent segments the tension adjustment function into independent components: a positioning component that can slide along the base and a fixing component that can adjust its position. This segmentation allows tension adjustment without requiring complex realignment of the entire belt system, making the operation simple and convenient while maintaining reliable tension control.
Solution Approach 2:
The positioning component and fixing component work together to enable self-adjustment of belt tension. The system allows users to easily modify tension by moving these components to different positions, eliminating the need for cumbersome realignment procedures while maintaining precise tension control.
3Device complexity
If a conventional belt tension adjustment mechanism is used, then the structure may be simple, but the tension adjustment is cumbersome and not rapid
Solution Approach 1:
The patent creates a dynamic adjustment system where the positioning component can be quickly moved to different positions along the base and the fixing component can be rapidly adjusted. This dynamic design enables fast tension adjustment without requiring complex mechanisms, achieving both simplicity and speed in the adjustment process.

Implementation Method 1
The first free end has an inclined guiding structure and is movably inserted into the first slot. The first fixing component abuts against the inclined guiding structure and is movably locked with the first hole.
Implementation Method 2
The movement of the free end can result in the resilient deformation of the positioning component, and the motor can be moved relative to the base accordingly.
