Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purifiers face challenges in efficiently cleaning and replacing pre-filters due to integrated structures that are difficult to disassemble, leading to prolonged cleaning times and potential environmental pollution from discarded filters.
Innovation Solution
An air purifier design featuring a detachable filter frame and cover frame system that supports a flexible filter member, allowing easy detachment and cleaning by hand, and quick replacement of the filter member, reducing weight and volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the filter net and frame are integrated, then the structural strength is improved, but the ease of cleaning deteriorates
Solution Approach 1:
The filter assembly is divided into separate components: the filter net and the frame are detachably connected rather than integrated. This allows the filter net to be easily removed for cleaning while the frame remains, resolving the contradiction between structural strength and ease of cleaning.
Solution Approach 2:
The filter net is extracted as a separate removable component from the frame structure. This extraction enables independent cleaning of the filter net without disassembling the entire frame, maintaining structural integrity while improving cleanability.
2Reliability
If the filter is made of microfiber material, then the filtration performance is improved, but the cleaning time increases
Solution Approach 1:
The microfiber filter is segmented as a separate removable net from the frame, allowing it to be quickly detached and cleaned independently. This reduces cleaning time compared to integrated designs where the entire assembly must be disassembled.
Solution Approach 2:
The filter net is designed to be easily removable and cleanable by the user without requiring specialized tools or complex disassembly procedures. The simple detachable connection enables users to quickly remove and clean the microfiber filter themselves.
3Stability of the object's composition
If the filter unit is made of plastic or metal frame, then the structural rigidity is improved, but the manufacturing cost increases
Solution Approach 1:
Instead of making the entire filter unit from rigid plastic or metal, only the frame structure uses these materials for localized rigidity where needed. The filter net itself uses flexible, lower-cost materials, reducing overall manufacturing cost while maintaining necessary structural stability.
Solution Approach 2:
The design combines a simple rigid frame (providing structural support) with a flexible filter net (providing filtration). This merging of materials and functions achieves the necessary rigidity at lower cost compared to constructing the entire filter unit from expensive rigid materials.
4Strength
If the filter unit is made of plastic or metal, then the structural strength is improved, but the environmental compatibility deteriorates
Solution Approach 1:
The filter assembly is segmented into a durable reusable frame and a replaceable filter net. The frame can be reused multiple times, reducing waste, while the filter net can be replaced when exhausted, improving environmental compatibility compared to disposable integrated units.
Solution Approach 2:
The design enables recovery and reuse of the frame structure while the filter net is discarded and replaced. This selective discarding approach reduces overall waste compared to discarding entire integrated filter units, improving environmental compatibility.

AI summary
An air purifier includes a filter member for filtering pollutants in the air, a blower for providing blowing force to allow the air to pass through the filter member, a body frame accommodating the blower, a cover frame that forms a part of an appearance of the air purifier and is detachably coupled to the body frame, and a filter frame that is detachably coupled to the cover frame and detachably supports at least a portion of the filter member. When the filter frame is coupled to the cover frame, the filter member is positioned between the cover frame and the filter frame so that movement of the filter member is restricted, and when the cover frame is attached to and detached from the body frame, the filter member and the filter frame are attached and detached together with the cover frame.
