Oven Door Smoke Sensor Wireless Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smoke detectors often fail to detect smoke generated near kitchen stoves or ovens in a timely manner, leading to potential fires due to the delay in detection.
Innovation Solution
A smoke alarm system with a smoke detector housed in an enclosure that attaches to an oven door handle, transmitting a wireless signal to a remote receiver, which activates audio and visual alarms to alert occupants of smoke presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional remote smoke detectors are used, then they can detect smoke in the home, but they fail to detect smoke near kitchen stoves or ovens in a timely manner
Solution Approach 1:
The invention divides the smoke detection function into multiple locations: a primary smoke detector positioned near the kitchen stove/oven and secondary smoke detectors located throughout the home. This segmentation allows the primary detector to immediately detect smoke at its source while secondary detectors provide broader coverage, resolving the contradiction between fast local detection and reliable comprehensive detection.
2Speed
If a smoke detector is placed near the kitchen stove, then smoke detection speed improves, but the device complexity increases due to wireless transmission and remote alarming components
Solution Approach 1:
The primary smoke detector near the kitchen stove serves multiple functions: it detects smoke locally, transmits wireless signals to remote receivers, and can directly alarm. The remote receivers also serve dual purposes by receiving signals from the primary detector and functioning as independent smoke detectors themselves. This multi-functionality reduces overall system complexity while maintaining fast response capability.
3Area of stationary object
If smoke detectors are positioned away from the kitchen area, then they provide broader coverage, but valuable seconds are lost before smoke is detected
Solution Approach 1:
The detection network is segmented into a primary detector positioned strategically near the kitchen stove for immediate detection, and multiple secondary detectors distributed throughout the home for broad coverage. This segmentation allows the system to achieve both fast local response and comprehensive area coverage simultaneously.
Solution Approach 2:
The primary smoke detector acts as an intermediary between the smoke source in the kitchen and the remote detectors throughout the home. When it detects smoke, it immediately transmits wireless signals to remote receivers, providing early warning before smoke permeates throughout the entire home, thus bridging the gap between localized fast detection and broad coverage.

Data Source
AI summary
A smoke alarm system specifically designed to detect smoke near a kitchen stove includes a transmitter assembly having a smoke detection device housed within an enclosure which hangs upon an oven door handle or other such appendage. The transmitter assembly further comprises a transmitter module that generates a wireless signal upon detection of smoke and transmits the signal to a remote receiver. When activated by the signal from the transmitter assembly, the receiver assembly produces sound and illumination type alarms, thereby warning occupants of smoke that is emanating from the stove, and the need to take immediate corrective action.
