Surveillance Camera Self-Cleaning via Rotational Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surveillance cameras face challenges in effectively removing raindrops and dust from their lenses and light sources without causing scratches or requiring additional cleaning tools, which can impair their functionality and require manual intervention.
Innovation Solution
A method where the surveillance camera's main body is designed to rotate and strike a mounting bracket at controlled speeds, using the impact to dislodge debris while ensuring the lens and light shields are positioned to prevent cross-contamination and maintain operational alignment, thereby allowing for self-cleaning without external tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the main body rotates and strikes the mounting bracket to remove debris, then cleaning effectiveness is improved, but the risk of causing scratches or damage increases
Solution Approach 1:
The patent applies prior cushioning by designing a controlled rotation mechanism that limits the main body's rotation angle and speed before impact occurs. The rotation driver controls the rotational speed and angle, ensuring the impact force remains within safe limits that prevent scratches while still effectively removing debris from the lens and light source surfaces.
Solution Approach 2:
The patent implements dynamics by making the cleaning action controllable and adjustable through the rotation driver. The main body can rotate at controlled speeds and angles, allowing the impact force to be dynamically adjusted based on cleaning needs while preventing excessive force that could cause damage. The system transitions from static to dynamic controlled cleaning.
2Reliability
If additional cleaning tools are used to remove raindrops and dust, then cleaning capability is improved, but device complexity and maintenance requirements increase
Solution Approach 1:
The patent applies self-service by enabling the surveillance camera to clean itself without external intervention. The rotation driver automatically rotates the main body to strike the mounting bracket, dislodging debris from the lens and light source. This self-cleaning mechanism eliminates the need for separate cleaning tools, external maintenance personnel, or complex additional cleaning systems.
Solution Approach 2:
The patent implements multi-functionality by making the mounting bracket serve dual purposes: it provides structural support for the surveillance camera and acts as a cleaning surface during the self-cleaning process. The rotation mechanism that enables the main body to strike the bracket integrates the cleaning function into the existing structural components, avoiding additional dedicated cleaning mechanisms.
3Productivity
If the main body is rotated at high speed to increase cleaning impact, then debris removal effectiveness is improved, but the risk of misalignment and operational disruption increases
Solution Approach 1:
The patent applies feedback by incorporating a position correction mechanism that detects and corrects misalignment between the main body and mounting bracket after rotation. The position correction driver monitors the relative positions and adjusts them to ensure proper alignment is restored after the cleaning impact, maintaining both cleaning effectiveness and operational precision.
Solution Approach 2:
The patent implements periodic action by separating the cleaning operation from the normal surveillance operation. The main body rotates to a cleaning position, performs the impact cleaning, then returns to its original surveillance position. This periodic alternation between cleaning mode and operational mode ensures that high-speed rotation for cleaning does not disrupt the precision requirements during normal surveillance function.

AI summary
A clean method is configured for a surveillance camera. The surveillance camera comprises a mounting bracket and a main body which is rotatable relative to the mounting bracket so that the main body is rotatable around at least one rotation axis. The clean method includes the following steps. Drive the main body to rotate in a first path from a prepared position to an end of the first path, which is away from the prepared position, and to strike the mounting bracket to get the main body cleaned. Correct a relative position relationship between the main body and the mounting bracket.
