Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gas sensor is used to detect air quality in real-time, then the ability to warn people of hazardous gas exposure is improved, but the device becomes stationary and cannot follow the user throughout the environment
Solution Approach 1:
The system is divided into two independent modules: a portable gas detection module that the user carries to monitor air quality in real-time, and a stationary main body with purification capability. The detection module and main body communicate wirelessly, allowing the user to move freely while maintaining detection and purification functions.
Solution Approach 2:
A wireless communication system serves as an intermediary between the portable detection module and the main body. This allows data transmission and control signals to be exchanged without physical connection, enabling user mobility while maintaining system functionality.
2Adaptability or versatility
If a purification device is made mobile to follow the user, then the purification coverage can move with the user, but the device complexity increases due to adding driving and positioning components
Solution Approach 1:
The system separates the purification function (stationary main body) from the detection function (portable module). This segmentation allows the purification device to remain simple and stationary while the detection module handles mobility, thus achieving purification coverage mobility without significantly increasing the complexity of the main purification system.
Solution Approach 2:
The main body is designed to perform multiple functions: housing the purification module, serving as a base for the gas guider, and acting as a communication hub. This multi-functionality reduces the need for additional components, thereby limiting the increase in device complexity.
3Ease of manufacture
If the purification module is positioned far from the user, then the device can remain stationary and simple, but the purification effectiveness decreases as the cleaned air may not reach the user's breathing zone
Solution Approach 1:
The gas guider acts as an intermediary mechanism that actively transports purified air from the stationary purification module to the user's location. This ensures that even though the purification module remains stationary and simple, the cleaned air is delivered directly to the user's breathing zone, maintaining purification effectiveness.
Solution Approach 2:
The gas guider utilizes pneumatic principles to move air through channels and conduits from the purification source to the user. This allows the system to maintain a simple stationary purification module while ensuring purified air reaches the user's immediate vicinity, reducing hazardous gas exposure risk.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables real-time detection and purification of air quality, allowing users to avoid hazardous gas exposure and improve indoor air quality by moving the purification module to areas of need based on detected gas levels, effectively addressing the challenge of air pollution.
Implementation Method 1
The purification module is disposed in the gas-flow channel for filtering the gas introduced through the gas-flow channel
Implementation Method 2
The gas is inhaled through the at least one inlet, flows through the purification module for filtration and purification, and is discharged out through the at least one outlet

AI summary
A mobile gas detection and cleaning device including a main body, a purification module, a gas guider, a gas detection module a controlling module, a driving movement module and a position determining unit is disclosed. The gas detection module allows a user to carry for detecting gas in the environment around the user to obtain a gas detection datum, and a target position is wirelessly transmitted. The controller module receives the gas detection datum sent from the gas detection module and controls the gas guider according to the gas detection datum. The controller module receives the target position wirelessly sent from the gas detection module for estimating a target track from a remaining distance relative to the target position and the main body. The driving movement module is controlled to move the main body along the target track to reach an area nearby the user for purifying the gas.
