Solution Overview
Problem
Existing air-processing apparatuses face limitations in maximizing outlet discharge area and providing clear operational state information, with reduced outlet area due to motor placement and limited visibility of operational lamps.
Innovation Solution
An air-processing apparatus with a rotatable louver and integrated optical output structure, featuring a lamp, printed circuit board, and transparent panel, allows light emission through the louver vanes to enhance visibility and information provision, while the louver-driving device is positioned to expand the outlet area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a driving motor for changing the orientation of the vanes is disposed on one side of the vane in the leftward-rightward direction, then the louver structure is simplified, but the outlet area is reduced
Solution Approach 1:
The louver is divided into multiple independent vanes (first vane, second vane, third vane, fourth vane) that can rotate independently around a central axis. This segmentation allows the driving motor to be positioned at the center rather than on one side, enabling the outlet to extend fully across the leftward-rightward direction and maximize outlet area while maintaining structural simplicity through modular design
Solution Approach 2:
The vanes are designed with asymmetric configurations relative to the central axis, with different numbers of vanes on each side (two vanes on one side, one vane on the other side). This asymmetric arrangement optimizes both the aerodynamic performance for air discharge and the spatial distribution of components, allowing the outlet to achieve maximum area while the driving mechanism remains centrally located
2Device complexity
If a lamp is disposed on the upper surface of the base panel, then the structure is simple, but the visibility of operational state indication is insufficient
Solution Approach 1:
The lamp is moved from a fixed position on the base panel to the louver structure, which rotates in the vertical direction. This dimensional change allows the lamp to dynamically adjust its orientation and position, providing visibility from multiple angles and directions depending on the louver's rotational position, thereby significantly improving operational state indication visibility without complicating the overall structure
3Device complexity
If a lamp provides only on/off or flashing information, then the device complexity is low, but the information provision capability is limited
Solution Approach 1:
Multiple lamps with different colors (first lamp, second lamp, third lamp) are integrated into the louver structure, each capable of emitting different colored light. This allows the system to convey diverse operational state information through color coding (e.g., green for normal operation, red for error, yellow for warning) while maintaining relatively simple device complexity, as each lamp independently provides distinct information channels
