Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless smoke detectors do not integrate a main breaker with a signal receiver to wirelessly connect with multiple detectors, nor do they provide a comprehensive smoke and fire safety system with illuminated exit signs and audible alarms.
Innovation Solution
A wireless smoke detector system that includes a breaker assembly with a main breaker and signal receiver, and a detector assembly with smoke detection, audible alarms, and colored LED lights, all wirelessly connected to guide users to exits during a fire and shut off electrical devices to prevent fire spread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless smoke detectors are installed without integration to main breaker and signal receiver, then device complexity is reduced and ease of manufacture is improved, but fire safety effectiveness deteriorates due to inability to shut off electrical devices
Solution Approach 1:
The patent combines multiple previously separate components (smoke detector, main breaker, signal receiver, illuminated exit signs) into an integrated wireless system. The smoke detector wirelessly communicates with the main breaker to automatically shut off electrical devices, and with illuminated exit signs to guide occupants to safety, creating a unified fire safety system that enhances reliability through component integration.
Solution Approach 2:
The integrated system performs multiple functions simultaneously: smoke detection, wireless communication, automatic main breaker tripping to shut off electrical devices, and illuminated exit sign activation. This multi-functionality allows a single system to address various aspects of fire safety (preventing fire spread through electrical shutdown and guiding evacuation) without requiring separate dedicated systems for each function.
2Reliability
If multiple wireless smoke detectors are connected to main breaker with signal receiver, then fire safety effectiveness is improved through coordinated response, but device complexity increases
Solution Approach 1:
The signal receiver acts as an intermediary device that receives wireless signals from multiple smoke detectors and translates them into actions (tripping the main breaker). This intermediary simplifies the wireless network architecture by providing a central coordination point, allowing multiple detectors to communicate without requiring complex peer-to-peer communication protocols between all detector pairs.
3Ease of operation
If illuminated exit signs with different colored LEDs and audible alarms are implemented, then user guidance effectiveness is improved, but manufacturing cost increases
Solution Approach 1:
The illuminated exit signs use different colored LEDs (red, yellow, green) to provide location-specific guidance information. Each color serves a specific purpose in guiding occupants through different zones or conditions, allowing the system to provide differentiated local guidance rather than uniform signaling throughout the facility.

Data Source
AI summary
A wireless smoke detector including a breaker assembly and a detector assembly. Breaker assembly includes a main signal receiver operatively connected to a main breaker, wherein the signal receiver is configured to receive a signal from the detector assembly by a wireless communication transmitter when the smoke detector detects smoke, thereby the main breaker may interrupt the power supply of the facility. Detector assembly is capable of being wirelessly connected to a plurality of embodiments thereof to guide the user and hearing and/or seeing impaired users to the exit by a predetermined colored light and predetermined audible alarms emitted from each smoke detector installed on the ceiling above the doorways.
