Portable air purifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable air purifiers face damage due to impact concentration on coupling portions between the case and components, leading to potential damage during handling or falls.
Innovation Solution
A portable air purifier design featuring a case with protruding support surfaces that couple the fan cover and filter module in a front-rear direction, distributing impact influence widely and simplifying the coupling process, while through-holes in a honeycomb structure on the case surface enhance airflow and structural rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If portable air purifier components are coupled to the case, then the device can be assembled and function, but the coupling portions become vulnerable to impact damage
Solution Approach 1:
The patent applies beforehand cushioning by designing the case with recessed portions that receive protruding portions of components, creating a cushioning effect that absorbs impact before it reaches the coupling portions. The recessed structure acts as a pre-positioned protective mechanism that mitigates impact forces during drops or collisions, preventing damage to the coupling areas before they can be affected by harmful impacts.
Solution Approach 2:
The patent uses an intermediary approach by introducing the recessed portions as a mediating structure between the case and the components. These recessed portions serve as an intermediate zone that distributes and absorbs impact forces, acting as a buffer that protects the actual coupling portions from direct impact exposure. The recessed structure mediates the transmission of impact forces, preventing them from concentrating on vulnerable coupling areas.
2Ease of manufacture
If multiple components are separately coupled to the case, then each component can be securely attached, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent applies merging by combining multiple coupling operations into a single integrated assembly step. The components are designed with protruding portions that align with recessed portions in the case, allowing multiple components to be coupled simultaneously in one action rather than requiring separate coupling operations for each component. This merging of coupling steps simplifies the assembly process and reduces manufacturing complexity.
Solution Approach 2:
The patent uses segmentation by dividing the case into multiple recessed portions, each designed to receive a specific component's protruding portion. This segmentation allows for modular assembly where components can be independently designed and manufactured, then easily attached to their corresponding recessed portions. The segmented structure simplifies the overall assembly process by providing clear, pre-defined coupling locations for each component.
