Rotatable Lens Bracket for Security Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security camera systems with multiple lens assemblies face challenges in adjusting the position of lens assemblies without creating blind spots, as they are typically fixed and require changing the housing to reposition, limiting flexibility and coverage.
Innovation Solution
A lens bracket system with a moving portion, hooking portion, and stopper mechanism that allows for rotatable and detachable lens assembly placement on a circular rail, enabling independent adjustment of lens assemblies and preventing rapid position changes to maintain optimal coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lens assemblies are fixed at particular positions using screws or bolts, then the housing structure is simple and stable, but the positions of lens assemblies cannot be changed, generating blind spots
Solution Approach 1:
The housing is divided into a fixed portion and a moving portion. The lens bracket with lens assemblies can be independently moved along the rail relative to the fixed housing portion, allowing position adjustment without changing the overall housing structure.
Solution Approach 2:
The lens bracket is designed to be movable along the rail through the interaction of the hooking portion and rail protrusion. This dynamic structure allows the lens assemblies to be repositioned to eliminate blind spots while maintaining a simple fixed housing structure.
2Adaptability or versatility
If lens assemblies are fixed at various positions, then coverage is improved, but the housing needs to be changed to arrange lens assemblies at different positions
Solution Approach 1:
The lens bracket is separated from the housing as an independent movable component. The rail is integrated into the housing, while the lens bracket with hooking portion can slide along the rail, enabling position changes without housing modification.
Solution Approach 2:
The rail structure serves multiple functions: it guides the movement of the lens bracket, provides positioning through rail protrusions, and enables the lens assemblies to be arranged at various positions without requiring different housing designs.
3Adaptability or versatility
If lens assemblies are made detachable for repositioning, then flexibility is improved, but the connection structure becomes more complex
Solution Approach 1:
The connection between the lens bracket and housing is made dynamic through the hooking portion that can engage and disengage from rail protrusions. This allows easy attachment and detachment without complex fastening mechanisms.
Solution Approach 2:
The rail protrusion acts as an intermediary element between the housing and lens bracket. The hooking portion engages with the rail protrusion to transmit motion and force, simplifying the connection structure while enabling detachable repositioning.
4Speed
If the lens bracket can be rapidly repositioned, then response time is improved, but position stability may be compromised
Solution Approach 1:
The rail is provided with multiple rail protrusions at different positions. The hooking portion can engage with different rail protrusions to achieve periodic positioning stops, allowing rapid repositioning while maintaining stability at each positioned location.
