Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifiers have limitations in maximizing indoor air purification efficiency due to fixed purification abilities and inefficiencies when used in varying indoor spaces, and combining different types of purifiers does not effectively enhance purification capacity.
Innovation Solution
An air purifier system comprising multiple air purification modules with independent control over fan operation, flow path openings, and sensor units for motion and dust detection, allowing flexible operation modes and capacity adjustments based on space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed air purification ability is used, then the device structure is simple, but the purification efficiency cannot be maximized in varying indoor spaces
Solution Approach 1:
The patent implements a rotatable flow path dividing portion that can dynamically change the discharge direction of purified air, and a blowing fan with variable speed control. These dynamic elements allow the air purifier to adapt to different indoor space configurations and optimize purification efficiency for various room sizes and layouts, resolving the contradiction between fixed structure and variable performance requirements.
Solution Approach 2:
The system changes operational parameters including fan rotation speed, flow path discharge direction, and purification module activation status based on detected space characteristics. By adjusting these parameters rather than changing the physical structure, the system achieves high purification efficiency across varying indoor spaces while maintaining relatively simple device architecture.
2Productivity
If multiple air purification modules are combined, then the purification capacity is enhanced, but the control complexity increases
Solution Approach 1:
Each air purification module is equipped with its own blowing fan and flow path dividing portion that can operate independently. The modules perform self-service by autonomously controlling their own discharge directions and operational status based on space requirements, eliminating the need for complex centralized control systems while still achieving enhanced overall purification capacity through coordinated operation of multiple modules.
3Adaptability or versatility
If the flow path is fixed, then the device structure is simple, but the adaptability to different discharge directions is limited
Solution Approach 1:
The flow path dividing portion is designed to be rotatable, allowing it to dynamically redirect the discharge direction of purified air. This dynamic mechanism enables the air purifier to adapt to different room configurations, door positions, and air flow requirements without requiring multiple fixed flow path structures, thus achieving high adaptability with relatively simple device architecture.
