Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifying devices lack the flexibility to perform multiple functions such as rapid air distribution and humidity control, and often require complex configurations to achieve these functionalities.
Innovation Solution
An air purifying device with a detachable function module that includes a fan, an auxiliary controller, a connection terminal, and a second power supply, allowing it to assist the main air purification function or perform different functions like boosting air distribution or controlling humidity, while operating independently or in conjunction with the main device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an air purifying device is designed to perform multiple functions (air purification, rapid air distribution, humidity control), then the versatility and adaptability of the device is improved, but the device complexity increases
Solution Approach 1:
The air purifying device is divided into a main body module and detachable function modules. The main body module contains the power supply and control system, while separate function modules (first function module with first fan, second function module with second fan, humidifying module) can be selectively attached to provide different functions. This segmentation allows the device to perform multiple functions without permanently increasing system complexity.
Solution Approach 2:
The main body module is designed as a universal platform that can accommodate multiple different function modules through standardized connection terminals. The power supply and control systems in the main body can support various function modules, allowing a single device to perform air purification, rapid air distribution, and humidity control functions by simply changing the attached function module.
2Productivity
If multiple function modules are integrated into the air purifying device to assist the main air purification function, then the productivity and efficiency of air distribution is improved, but the device complexity increases
Solution Approach 1:
The device uses separate, detachable function modules (first function module, second function module) that can be independently attached to the main body. Each module has its own fan and control circuitry, allowing them to operate independently to assist air distribution without creating a complex integrated system.
Solution Approach 2:
The function modules are designed to be dynamically attachable and detachable from the main body through connection terminals. This dynamic configuration allows the system to adapt its complexity level based on operational needs - modules can be attached when high productivity is needed and removed when simpler operation is sufficient.
3Ease of operation
If function modules are made detachable to allow flexible configuration, then the ease of operation and adaptability is improved, but the reliability of electrical connection may worsen
Solution Approach 1:
The electrical connection system is segmented into separate connection terminals on both the main body and function modules. These terminals are designed to establish reliable electrical connections when modules are attached, while allowing easy detachment. The segmented design maintains reliability through standardized contact points while preserving operational flexibility.
Solution Approach 2:
The connection terminals are designed to dynamically transition between connected and disconnected states. When function modules are attached, the terminals establish stable electrical connections for power and control signals. When detached, the connections are cleanly broken without damage. This dynamic design allows frequent reconfiguration while maintaining connection reliability during operation.
