Heating Appliance Window Detection Using CO2 and Temperature Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating appliances struggle to robustly and reactively detect the opening or closing of windows or doors using temperature sensors alone, as temperature changes may be insufficient for reliable detection, leading to inefficiencies in heating regulation.
Innovation Solution
A method utilizing both CO2 and temperature sensors to determine the state of an opening, with the heating device transitioning to a regulation mode upon detection of a state change by either sensor, enhancing detection robustness and responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature sensors are used to detect window opening/closing, then the heating system can respond to environmental changes, but the detection reliability is insufficient when temperature changes are small
Solution Approach 1:
The patent combines temperature sensors and CO2 sensors into a unified detection system. The control unit processes signals from both sensor types simultaneously, using temperature changes to detect opening/closing events and CO2 concentration changes to confirm and validate these detections, thereby improving overall detection reliability while maintaining manageable system complexity through integrated processing.
Solution Approach 2:
The control unit acts as an intermediary that receives and processes signals from both temperature sensors and CO2 sensors. It correlates data from both sensor types to make definitive opening/closing detections, using the intermediary processing logic to reconcile sometimes conflicting or incomplete signals from individual sensors into reliable detection results.
2Speed
If only temperature sensors are used, then the device structure remains simple, but the response speed to opening/closing events is delayed
Solution Approach 1:
The patent merges temperature sensing and CO2 sensing capabilities into a single integrated system. The control unit monitors both temperature variations and CO2 concentration changes simultaneously, enabling faster detection of opening/closing events by utilizing CO2 concentration changes which can occur more rapidly than temperature changes when windows are opened.
3Measurement precision
If temperature sensors alone are used for detection, then the system is easier to operate, but the detection accuracy is insufficient for short-duration openings
Solution Approach 1:
The patent combines temperature-based detection and CO2-based detection into a unified control logic. The control unit cross-references signals from both sensor types, using CO2 concentration changes to detect and confirm short-duration opening events that may not produce sufficient temperature changes for reliable detection by temperature sensors alone, thereby improving overall detection accuracy.
