Air Purifier with Sliding Case Design for Expanded Discharge Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purifiers have limited usability due to restricted air discharge, primarily focusing on upper and lower portions, which hinders effective air purification above the device and reduces the area that can be cleaned.
Innovation Solution
An air purifier design featuring a first and second case with adjustable length, where the second case can be moved to change the vertical length, allowing for optimized air suction and discharge through different modes, including a power mode for increased suction and discharge efficiency by altering the alignment of holes and discharge ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the air purifier uses a fixed position with suction inlet and discharge outlet on lateral surfaces, then the device structure is simple, but the air purification area is limited and clean air cannot be easily supplied to regions above the air purifier
Solution Approach 1:
The air purifier implements a movable second case that can shift vertically relative to the first case, transforming the fixed discharge structure into a dynamic one. This allows the discharge outlets to reposition between upper and lateral surfaces, expanding the air purification area to include regions above the device while maintaining structural simplicity through a relatively simple sliding mechanism
Solution Approach 2:
The invention adds vertical dimensionality to the discharge outlet positioning by enabling the second case to move vertically. This allows discharge outlets to access different spatial zones (upper region when case is raised, lateral region when case is lowered), thereby expanding the three-dimensional air purification coverage without significantly complicating the device structure
2Area of stationary object
If the air purifier main body is lifted up and down to purify air in upper and lower portions, then the air purification coverage is improved, but the operation is restricted to upper and lower portions only, limiting usability
Solution Approach 1:
The air purifier equips different discharge portions with specialized functions: the first discharge portion (on the first case) is optimized for lateral discharge to purify lower regions, while the second discharge portion (on the movable second case) is optimized for upper discharge when the case is raised. This local specialization allows each discharge portion to excel at its designated function, providing versatile usability across different operational modes rather than forcing a single discharge method
3Productivity
If the second case is moved to change vertical length for optimized air suction and discharge, then air purification efficiency is enhanced, but the device complexity increases
Solution Approach 1:
The movable second case that can shift vertically relative to the first case transforms the fixed structure into a dynamic one, allowing real-time optimization of air suction and discharge paths based on operational needs. This dynamic configuration enhances air purification efficiency by enabling better alignment of suction inlets and discharge outlets, while the relatively simple sliding mechanism keeps the added complexity minimal
Solution Approach 2:
The movable second case serves multiple functions: it acts as a structural housing, provides a mounting platform for the second discharge portion, enables vertical positioning adjustment, and facilitates mode switching between power and normal operations. This multi-functionality consolidates several features into a single component, enhancing air purification efficiency without proportionally increasing device complexity

AI summary
An air purifier includes a first case and a second case that are insertably coupled such that the second case slides up and down with respect to the first case. The first case may suction air through a suction space provided at a bottom and a plurality of holes formed in a side wall. The second case may include a discharge grill provided at a top end through which air is discharged and a plurality of holes formed in a side wall through which air is suctioned when the second case is moved down to a first position and through which air is discharged when the second case is moved up to a second position. The top discharge grill may be opened and closed. The second case may also include a side discharge portion formed in the side wall above the plurality of holes. The side discharge portion may be opened and closed.
