Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decentralized ventilation devices lack the flexibility to be individually adapted to specific ventilation or air conditioning tasks in rooms, requiring complex redesign or retrofitting to meet varying requirements.
Innovation Solution
A modular decentralized ventilation device structure that allows for easy adaptation by combining different modules, with the heat recovery module designed as a frame module outside the room and supply, exhaust, and recirculation modules as room modules, enabling efficient space utilization and task-specific configuration.

Engineering Contradiction Analysis
1Adaptability or versatility
If a decentralized ventilation device is designed with fixed structure to meet specific ventilation tasks, then the ventilation performance for that specific task is optimized, but the device cannot be easily adapted to other ventilation or air conditioning tasks
Solution Approach 1:
The ventilation device is divided into separate functional modules including a supply air module, exhaust air module, and heat recovery module. Each module can be independently configured, installed, or removed based on the specific ventilation or air conditioning requirements of the room, enabling flexible adaptation without redesigning the entire system.
Solution Approach 2:
The modular design allows the same basic modules to serve multiple functions depending on configuration. The supply air module can provide fresh air for ventilation or cooled air for air conditioning, the exhaust air module can remove stale air or provide heating, and the heat recovery module can operate in different modes, making the system universally applicable to various tasks.
2Ease of operation
If a decentralized ventilation device is designed with all modules distributed over large distances to optimize individual module placement, then each module can be positioned optimally, but the device structure becomes complex and difficult to assemble
Solution Approach 1:
Multiple functional modules (supply air module, exhaust air module, heat recovery module) are combined into a single integrated housing unit. This merging allows all modules to be positioned close together within the same device structure, simplifying assembly and installation while maintaining the functional independence of each module through internal separators and ducting.
