Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water-cooled fans primarily offer humidification but lack air purification functionality, limiting their multifunctional capabilities.
Innovation Solution
A water-cooled fan design incorporating a detachable honeycomb or air filter unit with a circulating waterway and intelligent control mechanisms, allowing for selective use of either humidification or air purification based on user needs, reducing costs by providing dual functionality with a single unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a water-cooled fan with honeycomb structure is used, then humidification function is provided, but air purification function is not provided
Solution Approach 1:
The fan unit is designed to accommodate multiple functional modules (honeycomb for humidification, air filter unit for purification) in the same installation slot, allowing a single device to perform both humidification and air purification functions. The water supply unit can selectively wet different modules based on which one is installed.
Solution Approach 2:
The functional components (honeycomb and air filter unit) are designed as detachable, independent modules that can be separately installed or removed from the installation slot. This segmentation allows users to configure the device for different functions by simply changing the module in the slot.
2Adaptability or versatility
If separate devices are provided for humidification and air purification, then both functions are achieved, but cost increases
Solution Approach 1:
The patent combines multiple functional modules (honeycomb humidification module and air filter unit) into a single fan device with a common installation slot and water supply system. This merging allows both humidification and air purification capabilities to coexist in one device, reducing the total number of separate devices needed.
Solution Approach 2:
The fan unit serves as a universal platform that can accommodate different functional modules, making a single device capable of performing multiple functions (humidification, air purification) that would traditionally require separate devices.
3Reliability
If the water supply unit continuously operates, then humidification effect is maintained, but energy consumption increases
Solution Approach 1:
The control unit receives signals from the identification unit to detect which module is installed and automatically adjusts the water supply operation accordingly. When an air filter unit is detected, water supply is stopped; when a honeycomb module is detected, water supply is activated. This feedback mechanism ensures energy is only consumed when humidification is actually needed.
Solution Approach 2:
The water supply operation transitions from continuous static operation to dynamic conditional operation. The system adaptively changes its behavior based on real-time detection of the installed module type, activating water supply only when the honeycomb module is present and deactivating it when the air filter unit is installed.

Function Achieved in This Case
Enables efficient water cooling or air purification as needed, reducing costs and enhancing user flexibility by utilizing a single unit for both functions.
Implementation Method 1
The bottom end of the honeycomb structure is wetted in the water supply unit
Implementation Method 2
a water pump is disposed between the water tank and the water sink, and the water tank, the water pump, the water sink, and the installation slot are sequentially connected to form a circulating waterway
Implementation Method 3
a fan unit corresponding to the air inlet or the air outlet

AI summary
A water-cooled fan includes a body having an air inlet and an air outlet; a fan unit corresponding to the air inlet or the air outlet; an installation slot placed between the air inlet and the air outlet; and a water supply unit disposed above the installation slot. A method for controlling a multifunctional fan includes configuring a functional space and providing a water supply unit at a top end of the functional space; optionally providing a honeycomb or an air filter unit in the functional space; and when the honeycomb is provided in the functional space, providing, by the water supply unit, dampening water for the honeycomb. The present invention can selectively achieve the effect of air humidification or air purification by using a honeycomb or an air filter unit as needed, and the water-cooled fan of the present invention has high intelligence. A multi-purpose set reduces the cost.
