Solution Overview
Problem
Conventional respiration measurement devices are large, complex, and difficult to use outside of hospitals or homes, and their integral sensor and air flow path design makes it hard to wash and remove foreign substances, limiting their portability and accuracy.
Innovation Solution
A respiration measurement device with a detachable sensor and air flow path configuration, featuring differential pressure generation blocks and a respiratory pressure adjustment unit, allowing for easy cleaning and increased sensitivity, while being compact enough for use anywhere.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the sensor and air flow path are formed integrally, then the device structure is simplified, but foreign substances cannot be easily washed and removed
Solution Approach 1:
The device is divided into a first body containing the air flow path and a second body containing the sensor, which are detachably coupled together. This segmentation allows the air flow path to be separated from the sensor, enabling easy washing and removal of foreign substances from the air flow path while maintaining structural simplicity through the detachable coupling mechanism.
2Measurement precision
If the device has a complicated inner structure, then measurement accuracy can be maintained, but the device size becomes very large and difficult to carry around
Solution Approach 1:
By separating the sensor and air flow path into two independent bodies that can be detachably coupled, the device achieves a compact overall size that is easy to carry, while maintaining measurement accuracy through the preserved functional integrity of each component when coupled together.
3Adaptability or versatility
If the device is designed for portability, then it can be used anywhere, but the structure becomes more complex with detachable components
Solution Approach 1:
The device is segmented into a first body with air flow path and a second body with sensor, connected by a detachable coupling mechanism. This segmentation enables portability and versatility for use anywhere, while the coupling mechanism maintains structural simplicity by providing a straightforward connection interface between the two bodies.

AI summary
The present invention comprises: a first body which has an air flow path formed therein to allow air generated by respiration of a user to be introduced and moved therethrough, a part of the air flow path being opened to form an opening; a second body which includes a respiration measurement unit for measuring the pressure of air moving through the air flow path, is detachably formed at the first body, and is installed to close the opening formed through the first body; and a mouthpiece which is detachably coupled to the inlet side of the air flow path. According to the present invention, the size of a respiration measurement device is reduced, so that the respiration volume of an examinee can be measured not only at home or in a clinic but also in an outdoor environment; and a second body in which a sensor for measuring a respiration air current is installed and a first body which has an air flow path for allowing a respiration air current to be moved therethrough are detachably formed, so that foreign substances produced at the sensor and the air flow path can be easily washed and removed.
