Solution Overview
Problem
Existing ventilation systems in buildings, particularly in confined spaces like operating rooms, are inefficient in rapidly renewing air, leaving 'dead areas' untouched and failing to homogenize air layers, leading to potential contamination risks and discomfort, with complex and costly installation requirements.
Innovation Solution
A ventilation system featuring a blowing device and a suction device with vertically distributed suction and blowing mouths, respectively, to ensure radial gas distribution and extraction, addressing the inefficiencies of previous systems by providing comprehensive air renewal and treatment without size limitations, adaptable to various spaces and easy to install.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If ceiling-mounted blowing mouth and wall suction mouths near the floor are used, then clean air can be blown directly to the operation table and pollutants can be driven close to the floor for evacuation, but the air renewal is not full and rapid, leaving dead areas where air is not renewed
Solution Approach 1:
The suction device is divided into multiple suction modules arranged vertically, with each module containing suction mouths at different heights. This segmentation allows the system to draw air from multiple levels simultaneously, eliminating dead areas and improving overall air renewal efficiency while maintaining pollutant removal capability.
Solution Approach 2:
The invention transitions from a single-plane suction system (near the floor) to a multi-level vertical distribution system. By adding the vertical dimension with suction mouths at ceiling level and intermediate heights, the system achieves comprehensive air circulation throughout the entire room volume, eliminating stagnant areas.
2Object-affected harmful factors
If ceiling-mounted blowing mouth and wall suction mouths near the floor are used, then clean air can be directed to the operation table, but the air in the room cannot be homogenized and remains distributed in several layers according to temperature and hygrometry gradients
Solution Approach 1:
The blowing device is segmented into multiple blowing mouths at different vertical levels, and the suction device is divided into multiple modules with suction mouths distributed across various heights. This segmentation enables simultaneous air exchange at multiple levels, disrupting temperature and hygrometry gradients and promoting homogeneous air distribution throughout the room.
Solution Approach 2:
The system maintains continuous air circulation at all vertical levels through coordinated blowing and suction operations. This continuous multi-level air exchange prevents the formation of stable stratified layers, ensuring ongoing homogenization of air composition, temperature, and humidity throughout the room.
3Adaptability or versatility
If ceiling and wall integration of ventilation elements is planned from building construction, then the ventilation system can be built-in, but the manufacturing and installation meet significant constraints and are expensive
Solution Approach 1:
The ventilation system is divided into independent, modular blowing and suction units that can be manufactured separately and installed independently. This modularity eliminates the need for complex pre-planning during building construction, allowing flexible installation in existing or new buildings without significant structural modifications, thereby reducing installation costs and complexity.
Solution Approach 2:
The ventilation modules are designed with universal applicability, featuring standardized interfaces and configurations that can be adapted to various building types and sizes. This universality allows the system to be deployed in different environments without custom manufacturing, significantly reducing production and installation costs while maintaining adaptability to different architectural contexts.
4Productivity
If vertical distribution of suction and blowing mouths is implemented, then rapid and complete air renewal is achieved eliminating dead areas, but the device complexity increases
Solution Approach 1:
The system is segmented into standardized modular units with repeating configurations of blowing and suction elements. This segmentation allows complex vertical air distribution to be achieved through simple, repeatable modules, reducing overall system complexity while maintaining comprehensive air renewal coverage throughout the room.
Solution Approach 2:
Multiple ventilation functions (blowing, suction, air distribution) are merged into integrated modular units that operate cooperatively. By combining these functions in compact, self-contained modules with vertical arrangement, the system achieves complete air renewal without requiring separate complex systems for each function, thereby managing device complexity effectively.
