Air Cleaner Tabletop Outlet Structure for Radial Air Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air cleaners struggle to efficiently utilize space above the device, prevent foreign substances from interfering with operation, minimize shape deformation, and ensure reliable electrical connections and power supply to upper structures, while maintaining air quality and preventing fluid entry into electronic units.
Innovation Solution
An air cleaner design featuring a first body with an inlet and outlet, a rotatable fan, and a second body that guides air radially outward, allowing the upper surface to function as a table, with a separable and adjustable structure, abrasion-resistant materials, and secure electrical connections, and a base to prevent flipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fan changing direction of air is fixed to an upper part of the air cleaner, then air flow direction can be changed, but it is difficult to modify an upper structure and utilize space above the air cleaner
Solution Approach 1:
The air cleaner is divided into a lower body (containing the fan and filter) and an upper body (functioning as a table). This segmentation allows the upper structure to be modified or removed independently, enabling space utilization above the air cleaner without being constrained by a fixed fan structure.
Solution Approach 2:
The fan structure is extracted from the upper part of the air cleaner and placed in the lower body. This extraction removes the constraint that prevented upper structure modification, allowing the upper body to serve as a functional table surface while the fan operates independently below.
2Productivity
If the outlet is opened in up-down direction, then filtered air can be discharged upward, but it is difficult to utilize a space above the air cleaner
Solution Approach 1:
The air discharge function is maintained in the vertical dimension (upward flow through the outlet) while the upper body extends into the horizontal dimension, creating a table surface. This dimensional separation allows both efficient air discharge and space utilization above the device.
3Adaptability or versatility
If objects are placed on an upper side of the air cleaner, then space can be utilized, but shape deformation caused by friction may occur
Solution Approach 1:
The upper body is constructed from composite materials with high friction resistance and shape stability. This allows the upper surface to function as a table that can bear objects without deforming, while maintaining the structural integrity needed for long-term use.
4Area of stationary object
If the upper surface area is increased for table use, then space utilization improves, but foreign substances may fall into the outlet
Solution Approach 1:
A protective structure acts as an intermediary between the table surface and the outlet, preventing foreign substances from falling into the outlet while maintaining the large table surface area. This intermediary structure ensures both space utilization and contamination prevention.
5Adaptability or versatility
If a separable structure is used for the upper body, then various table sizes can be configured, but electrical signal transmission may be unreliable
Solution Approach 1:
The electrical connection system is designed to be dynamic rather than fixed, allowing for reliable signal transmission even when the upper body is separated or reconfigured. This enables various table size configurations while maintaining dependable electrical connections between the lower and upper bodies.
