Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing odor measurement methods require significant time and effort, as exemplified by WO 2019/117099 A1, US 2015/219608 A1, WO 2018/061092 A1, and CN 205 879 922 U, which do not efficiently facilitate odor detection.
Innovation Solution
A measurement apparatus with a housing containing multiple openings, including an air inlet, a gas inlet, and an air outlet, equipped with a substrate featuring an odor sensor and a pump, such as a piezo pump, to manage airflow efficiently, allowing for easy odor measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If air is collected in a container for odor measurement, then odor measurement can be performed, but the measurement process requires a great deal of time and effort
Solution Approach 1:
The housing is divided into multiple openings (first opening, second opening, third opening) that segment the air intake and exhaust paths. This segmentation allows controlled air flow through specific paths to the odor sensor, enabling rapid measurement without requiring large container volumes and reducing measurement time while maintaining measurement capability
Solution Approach 2:
The pump unit creates controlled air flow through the multiple openings to the odor sensor. By using pneumatic principles to actively move air through defined paths, the system achieves rapid odor measurement without the time-consuming process of collecting air in containers
2Productivity
If multiple openings are provided in the housing for air flow control, then rapid odor measurement is enabled, but the device structure becomes more complex
Solution Approach 1:
The multiple openings in the housing serve multiple functions: the first opening introduces air containing the target substance, the second opening introduces reference air, and the third opening serves as an exhaust. This multi-functionality allows rapid odor measurement through controlled air flow paths while keeping the structural complexity manageable by integrating these functions into a single housing component
