Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fire detectors face challenges such as difficult installation, limited effectiveness due to door obstruction, inability to assist deaf individuals, and lack of escape route guidance, despite recommendations for their use in housing.
Innovation Solution
A fire detection system comprising two interconnected fire detection elements with lighting means, preferably LEDs, mounted on both sides of a door using a flexible bridge, allowing for easy placement and providing visual cues for escape routes, and connectivity to smartphones or alarm centers for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire detectors are mounted on doors using traditional screw fixation methods, then reliable detection is achieved, but installation becomes complex requiring drill and ladder
Solution Approach 1:
The patent extracts the fastening function from the detector unit itself and separates it into a door-mounted base that remains fixed while the detector can be independently positioned or replaced without complex installation tools
Solution Approach 2:
The patent introduces a door-mounted base as an intermediary element that simplifies installation by providing a pre-prepared mounting platform on the door, eliminating the need for drill and ladder during detector deployment
2Productivity
If acoustic alarm signals are used in fire detectors, then warning capability is provided, but deaf individuals cannot be alerted
Solution Approach 1:
The patent applies multi-functionality by equipping the fire detector with both acoustic alarm signals and visual light signals, enabling the device to serve multiple user groups including hearing and deaf individuals simultaneously
Solution Approach 2:
The patent uses color changes in the light-emitting components to provide visual alarm signals that can be perceived by deaf individuals, with different colors potentially indicating different alarm states or escape route conditions
3Measurement precision
If detectors are positioned to avoid door obstruction, then detection sensitivity is improved, but escape route guidance capability is lost
Solution Approach 1:
The patent applies local quality by positioning detectors at specific locations that optimize both smoke detection sensitivity and escape route visibility, with detectors strategically placed to monitor both fire conditions and provide directional guidance information
Solution Approach 2:
The patent uses color-coded light signals to convey escape route information, with different colors indicating safe escape paths versus dangerous areas, enabling visual guidance while maintaining detection effectiveness
