Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable air purifiers face challenges in providing effective air purification and lighting functions without increasing their size, ensuring ease of assembly, and maintaining airflow while integrating lighting and improved rigidity.
Innovation Solution
The design incorporates a fan module between the suction and discharge openings, with a filter and lighting portion strategically placed to ensure airflow and light distribution, using a reflector for uniform lighting and a support structure that enhances rigidity without increasing the device's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lighting portion is added to the portable air purifier, then lighting function is improved, but device size increases
Solution Approach 1:
The lighting portion is nested within the space between the discharge opening and the fan module, utilizing existing internal volume rather than adding external components. This allows the lighting function to be integrated without increasing the overall device dimensions.
Solution Approach 2:
The lighting portion is positioned in the vertical dimension between the discharge opening and fan module, rather than expanding horizontally or externally. This dimensional placement enables functional addition without volumetric increase.
2Adaptability or versatility
If a cable is added for lighting, then lighting function is improved, but air flow is interfered with
Solution Approach 1:
A cable guide structure acts as an intermediary element that channels the cable through the housing in a manner that prevents interference with air flow paths. The guide ensures the cable is positioned away from the air passage while still providing electrical connectivity for the lighting portion.
3Adaptability or versatility
If lighting components are added, then lighting function is improved, but structural rigidity decreases
Solution Approach 1:
The lighting portion is merged with the existing housing structure, sharing structural support elements rather than requiring separate mounting infrastructure. This integration maintains structural rigidity while accommodating the lighting function.
Solution Approach 2:
The housing structure serves multiple functions: it provides structural rigidity for the device and simultaneously serves as the mounting framework for the lighting portion. This multi-functionality eliminates the need for additional structural elements that would compromise rigidity.
4Volume of moving object
If lighting is added without a reflector, then device size is reduced, but light uniformity is poor
Solution Approach 1:
A reflector with a curved surface is employed to distribute light uniformly. The curved geometry of the reflector redirects light rays to achieve even illumination across the discharge opening without requiring additional space for multiple light sources or complex positioning mechanisms.
