Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for providing gas information through electronic devices are limited as they often rely on publicly available data that may not accurately reflect the user's location, and they fail to identify the source of abnormal gases, only displaying numerical values without context.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods use publicly available gas information from Meteorological Administration, then the system complexity is low, but the measurement precision and reliability are insufficient because the measurement location differs from user location
Solution Approach 1:
The patent replaces the mechanical approach of physically transporting gas samples to centralized laboratories with an electronic/optical system using gas sensors integrated into mobile devices. The sensor directly detects gas components at the user's location and transmits data electronically, eliminating the need for physical sample handling and centralized analysis infrastructure.
Solution Approach 2:
The patent enables the mobile device to perform self-diagnosis and self-monitoring of gas environments. The device autonomously collects gas data using its integrated sensor, processes the information locally, and provides immediate feedback to the user without requiring external laboratory services or manual intervention.
2Loss of information
If conventional methods only display numerical gas values, then the device complexity is low, but the information utility is limited because users cannot identify the source or cause of abnormal gases
Solution Approach 1:
The patent introduces an image recognition module as an intermediary between the gas sensor and the user interface. The camera captures images of potential gas sources, and the image recognition algorithm processes these images to identify objects or environments associated with the detected gas. This intermediary connects the numerical sensor data with visual context, enabling users to understand the source of abnormal gases without adding significant hardware complexity.
3Loss of information
If the system integrates gas sensor and camera for image-based gas detection, then the measurement precision and information completeness improve, but the device complexity and energy consumption increase
Solution Approach 1:
The patent implements periodic sampling of gas data and images rather than continuous monitoring. The system takes gas measurements and corresponding images at predetermined time intervals or when triggered by specific conditions. This periodic operation reduces energy consumption compared to continuous operation while still providing sufficient information for detecting gas sources and composition changes.
