Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for monitoring and managing carbon dioxide concentrations in specific environments, such as rooms, lack comprehensive solutions for accurately determining abnormal CO2 levels and providing timely, location-specific notifications and improvements, especially when the CO2 sensor is in close proximity to sources or moving.
Innovation Solution
A determination system comprising a mobile terminal with a CO2 sensor, a determination apparatus with a determination unit, and additional units for location information acquisition, image acquisition, and environmental sound measurement, which assesses CO2 concentration situations and measurement environments, and notifies users or contractors for corrective actions based on location and sensor data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a CO2 sensor is installed in a target facility to monitor carbon dioxide concentration, then the CO2 concentration can be detected, but the measurement accuracy deteriorates when the sensor is in close proximity to CO2 sources or moving
Solution Approach 1:
The patent introduces location information as an intermediary parameter to mediate between the CO2 sensor and the target facility. By acquiring location information of both the sensor and the target facility, the system can calculate distance and determine whether the sensor is in a suitable measurement position, thereby compensating for the harmful effects of proximity to CO2 sources and movement interference
Solution Approach 2:
The patent implements a feedback mechanism where the determination unit continuously evaluates the measurement situation based on location information and CO2 concentration data. When the sensor is determined to be in an unsuitable position (too close to CO2 sources or moving), the system provides feedback to indicate that the measurement should not be used, allowing for corrective action to maintain measurement accuracy
2Reliability
If existing systems monitor CO2 concentration in rooms, then CO2 levels can be tracked, but the systems lack comprehensive solutions for providing timely, location-specific notifications and improvements
Solution Approach 1:
The patent creates a multi-functional determination system that not only monitors CO2 concentration but also acquires location information, determines measurement situations, identifies abnormal states, and provides targeted notifications. This universal system handles multiple functions within a single integrated framework, improving reliability without requiring separate complex systems for each function
Solution Approach 2:
The patent segments the monitoring system into distinct functional units: a CO2 sensor for concentration detection, a location information acquisition unit for position data, and a determination unit for analysis. This segmentation allows each component to specialize in its specific function while working together to provide comprehensive location-specific monitoring and notification capabilities
3Measurement precision
If the CO2 sensor is placed close to CO2 sources for better detection, then sensitivity improves, but measurement accuracy deteriorates due to proximity effects
Solution Approach 1:
The patent uses location information as an intermediary to resolve the conflict between proximity and accuracy. By calculating the distance between the sensor and the target facility based on location data, the system can determine whether the sensor is appropriately positioned, allowing sensitive detection while maintaining measurement accuracy through distance verification
