Solution Overview
Problem
Conventional electronic devices equipped with gas sensors require additional holes for fluidic communication, which compromises their water-resistant characteristics, and existing solutions do not efficiently utilize existing holes for both sound and gas sensing functions.
Innovation Solution
Integrating a gas sensor with existing holes used for sound output or acquisition, such as microphone holes, to share the same opening, thereby eliminating the need for additional holes and enhancing water resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a gas sensor is equipped inside an electronic device, then gas measurement capability is improved, but additional holes must be added to the housing which worsens water-resistant characteristics
Solution Approach 1:
The patent applies multi-functionality by enabling existing holes in the housing to serve dual purposes: sound transmission for audio components and gas intake for the gas sensor. This allows the gas sensor to function without requiring dedicated additional holes, thereby maintaining water-resistant characteristics while achieving gas measurement capability
Solution Approach 2:
The patent merges the functions of sound transmission and gas sensing through shared holes in the housing. By combining these previously separate functions into common openings, the design eliminates the need for additional holes that would compromise water resistance, while still enabling both audio and gas sensing operations
2Adaptability or versatility
If additional holes are added to the housing for gas sensor, then gas sensing function is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The housing holes are designed to perform multiple functions simultaneously - serving as openings for audio components and for the gas sensor. This multi-functional design adds gas sensing capability without increasing the number of holes or complicating the housing structure
Solution Approach 2:
The existing holes in the housing automatically serve the gas sensor function without requiring separate dedicated openings. The housing structure itself provides the necessary openings for gas intake, eliminating the need for additional modifications to the housing design

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for effective gas measurement without compromising the water-resistant properties of the device, as the gas sensor utilizes existing openings used for sound functions, ensuring both functionality and durability.

AI summary
An electronic device includes a housing having a hole formed therein, an audio device inside the housing and communicating with an outside of the electronic device through the hole, a gas sensor inside the housing and communicating with the outside through the hole, a proximity sensor inside the housing, a wireless communication module inside the housing, and a processor inside the housing. The processor is configured to acquire data associated with air outside the electronic device by using the gas sensor, to recognize a user gesture of starting a proximity call by using the proximity sensor, and to calculate air quality of the outside air based on at least one of data acquired by the gas sensor before the proximity call starting gesture is recognized and data acquired by the gas sensor after a gesture of ending the proximity call is recognized. Other various embodiments are possible.
