Solution Overview
Problem
Conventional masks with high filter ratings can be difficult to breathe through and become less effective when the filter is contaminated, making them challenging to reuse, and existing airflow control masks are not easily assembled or stored.
Innovation Solution
A mask design incorporating a blower with magnetic coupling mechanisms for easy assembly and disassembly, allowing for airflow control and filter placement that is detachable and foldable for improved usability and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a high filter rating mask is used, then protection from harmful substances is improved, but breathability deteriorates
Solution Approach 1:
The patent applies dynamics by making the mask components detachable and reconfigurable. The mask body, blower, and filter can be separated and reassembled, allowing users to adjust the filter rating based on breathing comfort needs while maintaining protection effectiveness when required.
Solution Approach 2:
The mask is divided into separate modules: mask body, blower unit, and filter element. This segmentation allows each component to be independently optimized and replaced, enabling users to switch between different filter ratings depending on the balance between protection and breathability requirements.
2Ease of operation
If a detachable blower is added for airflow control, then breathability is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical coupling mechanisms with magnetic coupling systems. The magnetic attraction and repulsion forces enable automatic alignment and secure attachment of the blower to the mask body, significantly simplifying the assembly structure while maintaining detachable functionality for airflow control.
Solution Approach 2:
The magnetic coupling mechanism enables the blower to self-align and self-attach to the mask body without requiring manual adjustment or complex fastening procedures. The magnetic forces automatically engage the components when brought close together, reducing assembly complexity.
3Ease of manufacture
If magnetic coupling mechanisms are used for assembly, then ease of assembly is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent introduces magnetic fields as an intermediary force between the mask body and blower components. This magnetic intermediary enables automatic alignment and coupling without requiring precise mechanical fitting, as the magnetic forces naturally draw the components together and hold them in the correct position.
Solution Approach 2:
The magnetic coupling mechanism changes the coupling parameter from mechanical contact precision to magnetic field interaction. This allows for greater tolerance in manufacturing dimensions while maintaining reliable assembly, as magnetic forces can compensate for minor dimensional variations.
4Ease of operation
If the mask is made foldable for storage, then storage convenience is improved, but structural stability deteriorates
Solution Approach 1:
The mask is segmented into detachable modules that can be folded or separated for compact storage. The mask body, blower, and filter can be divided and stored separately or folded together, providing storage convenience while maintaining structural stability when assembled and worn.
Solution Approach 2:
The mask structure is designed to be dynamically reconfigurable, transitioning between a stable assembled state during use and a compact folded state for storage. The detachable connections allow easy transition between these states without compromising structural integrity in either configuration.

AI summary
A mask including a mask body and a blower. The mask body includes a first coupling part, and a second coupling part spaced apart from the first coupling part. The blower includes a third coupling part configured to be detachably couplable to the first coupling part and prevented from being coupled to the second coupling part, and a fourth coupling part configured to be detachably couplable to the second coupling part and prevented from being coupled to the first coupling part. With the third coupling part detachably coupled to the first coupling part and the fourth coupling part detachably coupled to the second coupling part, the blower is disposed to a rear of the mask body and is operable to force air to flow into and out of the mask.
