Surveillance Camera Bracket Fixing Member Rattle Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surveillance cameras installed outdoors often experience rattling due to wind pressure or vibration, which can lead to instability and image quality deterioration.
Innovation Solution
A surveillance camera design featuring a bracket with a rotation seat and a fixing member that presses and fixes the lower end surface of the bracket to the upper end surface of the main case, preventing movement and rattling by interposing the fixing member between the bracket and the main case.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If engagement pins are engaged with keyholes to support the camera case, then falling can be restricted, but slight looseness in engagement directions causes rattling in outdoor environments
Solution Approach 1:
A fixing member is introduced as an intermediary component between the bracket and the camera case. This fixing member includes a pressing portion that presses the camera case against the bracket, and a fastening portion that is fastened to the bracket, thereby mediating the connection and eliminating the looseness between the engagement pins and keyholes.
Solution Approach 2:
The fixing member is divided into two functional segments: a pressing portion that contacts and presses the camera case, and a fastening portion that is fastened to the bracket. This segmentation allows each part to perform its specific function optimally, with the pressing portion handling the stabilization of the camera case and the fastening portion securing the fixing member to the bracket.
2Ease of operation
If engagement pins are used to attach the camera case to the bracket, then the camera case can be supported, but wind pressure or vibration causes rattling due to engagement looseness
Solution Approach 1:
The fixing member serves as a mediator between the bracket and the camera case, providing additional stabilization without complicating the attachment process. The pressing portion presses the camera case against the bracket, while the fastening portion secures the fixing member, effectively reducing rattling from wind and vibration.
Solution Approach 2:
The fixing member is installed beforehand to prevent rattling before it occurs. The pressing portion continuously presses the camera case against the bracket, providing prior cushioning against the harmful effects of wind pressure and vibration, thereby preventing rattling rather than correcting it after the fact.

AI summary
A surveillance camera includes a bracket, a main case suspended and supported by the bracket, and a fixing member interposed between the bracket and the main case. The main case has a camera unit. The fixing member presses and fixes a lower end surface of the bracket and an upper end surface of the main case.
