Solution Overview
Problem
Conventional air cleaners with multiple modules face challenges in efficiently purifying air in both small and large indoor spaces due to airflow interference, as suction and discharge ports are not optimally aligned, leading to decreased air purification efficiency.
Innovation Solution
The air cleaner design features a stacking structure where the arrangement direction of suction and discharge ports in adjacent modules are opposite to each other, minimizing airflow interference and enhancing air purification efficiency by focusing airflow streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple small-capacity air cleaners are placed in a large indoor space, then air purification capacity is improved, but the area occupied by the air cleaners becomes too large
Solution Approach 1:
The air cleaner is divided into multiple detachable modules that can be stacked vertically. Each module contains independent suction and discharge components, allowing the system to achieve high purification capacity through vertical stacking rather than horizontal placement, thus reducing the floor area occupied.
Solution Approach 2:
The design transitions from horizontal placement of multiple units to vertical stacking, utilizing the vertical dimension to increase air purification capacity while minimizing the horizontal footprint. Modules are stacked in an alternating pattern to optimize airflow.
2Productivity
If a large-capacity air cleaner is placed, then air purification capacity for large spaces is improved, but it cannot simultaneously purify air in small indoor spaces
Solution Approach 1:
The system is segmented into modular units that can be stacked in different quantities depending on the space size. Users can configure the number of modules to match their specific needs, making the system adaptable to both small and large indoor spaces.
Solution Approach 2:
The modular design allows dynamic reconfiguration of the system. Modules can be added or removed based on the size of the indoor space, providing flexibility and adaptability across different application scenarios.
3Ease of manufacture
If conventional stacking structure with same-direction suction and discharge ports is used, then manufacturing simplicity is maintained, but airflow interference between adjacent modules increases
Solution Approach 1:
Adjacent modules are designed with asymmetric airflow orientations. One module has suction at the bottom and discharge at the top, while the adjacent module has suction at the top and discharge at the bottom. This asymmetric arrangement eliminates airflow interference between modules while maintaining manufacturing simplicity through standardized component design.
4Device complexity
If suction and discharge ports are not optimally aligned, then device complexity is reduced, but air purification efficiency decreases
Solution Approach 1:
The alternating stack design creates optimal airflow alignment where discharge ports of lower modules align with suction ports of upper modules in an asymmetric pattern. This configuration enhances airflow efficiency without requiring complex alignment mechanisms, as the pattern is achieved through simple modular stacking.
