Portable air caring apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable air caring apparatuses face issues with filter contamination due to the lack of a separate sanitizing apparatus, leading to degraded air cleaning performance and increased noise and vibration when mounted in small spaces like cup holders.
Innovation Solution
A portable air caring apparatus with a sanitizing portion installed between the filter portion and the fan module portion to sanitize the filter, minimizing airflow resistance and preventing sanitizing light exposure to the outside.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate sanitizing apparatus is installed inside the portable air caring apparatus, then the filter portion can be sanitized, but the sizes of the filter portion and fan assembly become smaller and air caring ability is degraded
Solution Approach 1:
The sanitizing apparatus is nested within the housing structure of the portable air caring apparatus, specifically positioned to utilize the existing internal space between the inlet and outlet. This allows the sanitizing function to be integrated without requiring additional external space, thereby preventing reduction in the sizes of the filter portion and fan assembly.
Solution Approach 2:
The sanitizing apparatus is positioned in a location that utilizes the vertical or lateral dimension within the housing, rather than occupying horizontal space that would reduce the filter and fan assembly sizes. This spatial arrangement allows all components to coexist without compromising air caring ability.
2Reliability
If a separate fixing bracket is additionally installed inside the case to fix the sanitizing apparatus, then the sanitizing apparatus can be secured, but the sizes of the filter portion and fan assembly become smaller and air caring ability is degraded
Solution Approach 1:
The fixing function is merged with the existing housing structure. The housing itself is designed to accommodate and secure the sanitizing apparatus, eliminating the need for a separate fixing bracket. This integration prevents additional components from occupying space needed by the filter portion and fan assembly.
3Ease of manufacture
If the sanitizing apparatus is fixed to the fan module portion, then the sanitizing apparatus can be installed, but the sanitizing light interferes with the filter case and sanitization of the filter portion is not performed properly
Solution Approach 1:
The sanitizing apparatus is extracted from the fan module portion and repositioned to a separate location within the housing. This separation eliminates the interference between the sanitizing light and the filter case, allowing the filter portion to be properly sanitized without obstruction.
4Ease of manufacture
If the sanitizing apparatus is installed at the fan module portion, then the sanitizing apparatus can be installed, but frictional resistance between the sanitizing apparatus and air increases and air blowing ability is degraded
Solution Approach 1:
The sanitizing apparatus is extracted from the fan module portion and positioned in a location that does not obstruct the airflow path. This repositioning reduces frictional resistance between the air and the sanitizing apparatus, thereby maintaining air blowing ability.
5Device complexity
If the case is formed in a rectangular parallelepiped shape with corners at the outer side, then the case structure is simple, but it causes inconvenience when held and creates gaps in cup holders leading to vibration and noise
Solution Approach 1:
The case is designed with a curved surface instead of a rectangular parallelepiped shape. This curved configuration eliminates corners at the outer side, providing ergonomic convenience for holding and preventing gaps when mounted in cup holders, thereby reducing vibration and noise without significantly increasing structural complexity.
