Call Point Safety Light Bracket for Uniform Emergency Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency lighting solutions for manual fire alarm call points often fail to provide sufficient illumination during power cuts, making them difficult to recognize in emergency situations.
Innovation Solution
A safety light is retrofitted to the call point, comprising a spacer bracket secured between the front and rear panels, with a housing containing a light source positioned to overhang and illuminate the front surface, ensuring uniform illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a light is integrated into a call point to indicate when a camera is active, then the camera's presence and operation become more noticeable to passersby, but the call point's primary function as a safety device may be compromised if the light malfunctions or fails to activate
Solution Approach 1:
The patent uses different colored lights to convey different states: green LED indicates the camera is active and recording, while amber LED indicates the call point is in alarm mode. This color-coding system allows the noticeability function and safety function to operate independently without interference, as each color has a specific meaning that does not conflict with the other state indications
Solution Approach 2:
The lighting system is divided into separate functional segments: a green LED for camera status indication and an amber LED for alarm status indication. This segmentation allows each light to serve its specific purpose independently, so that the camera noticeability function does not interfere with the safety alarm function, and vice versa
2Reliability
If a camera is installed in a call point to detect intruders, then the safety monitoring capability is enhanced, but the device complexity increases due to integration of multiple systems
Solution Approach 1:
The call point device is designed to perform multiple functions within a single integrated unit: it serves as both a safety alarm device and a camera monitoring system. The controller manages both the camera operation and the call point alarm function, allowing one device to replace what would traditionally require separate systems, thereby reducing overall system complexity while maintaining enhanced safety capabilities
Solution Approach 2:
The patent combines the camera system and call point alarm system into a single integrated device. The camera, lighting system, and alarm function are merged into one unit that can be installed in existing call point boxes, eliminating the need for separate camera mounting and reducing installation complexity while maintaining both safety monitoring and intrusion detection capabilities
3Ease of manufacture
If existing call point boxes are used to house camera equipment, then installation cost and complexity are reduced, but the internal space and structural design of the box must accommodate additional components
Solution Approach 1:
The camera and lighting components are nested within the existing call point box structure. The camera module and LED lighting system are designed to fit inside the standard call point enclosure, utilizing the existing housing space efficiently. This nesting approach allows the additional functionality to be accommodated within the原有 structure without requiring a completely new housing design, thereby maintaining ease of installation while managing internal space constraints
