Respiratory Mask Front Cover Slide Guide and Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing respiratory protection masks lack a simple and secure mechanism for easy assembly, disassembly, cleaning, and replacement of components, particularly the front cover, which covers the air-outlet valve, to maintain the mask's effectiveness and hygiene.
Innovation Solution
A respiratory protection mask design featuring a guide structure with a slide rail on the main body and a slide channel on the front cover for linear movement, combined with a limiting structure including male and female fasteners that allow for secure assembly and flexible detachment, enabling easy cleaning or replacement of the front cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable cap is provided to cover the air-outlet valve, then the valve can be protected and easily cleaned, but the assembly and disassembly process becomes complex
Solution Approach 1:
The front cover is segmented from the main body of the mask, allowing it to be detached for cleaning and maintenance. This segmentation enables independent access to the air-outlet valve and other components without disassembling the entire mask structure.
Solution Approach 2:
The air-outlet valve is nested within the front cover, which itself is integrated into the main body. This nested structure allows the valve to be protected by the cover while remaining accessible when the cover is removed, simplifying the overall assembly compared to separate cap-and-valve designs.
2Reliability
If multiple fastening points are provided for secure attachment, then the connection between front cover and main body is more reliable, but the assembly and disassembly process becomes more difficult
Solution Approach 1:
Multiple fastening functions are merged into a single integrated fastening structure that spans across the front cover and main body. This unified fastening mechanism provides reliable multi-point attachment while maintaining simple operation through a single action for both assembly and disassembly.
Solution Approach 2:
The fastening structure incorporates dynamic elements that allow it to transition between a locked state during normal use and an unlocked state during assembly or disassembly. This dynamic characteristic enables secure attachment during wear while facilitating easy removal when needed for cleaning or maintenance.

AI summary
A respiratory protection mask includes detachably connected main body and front cover. The main body includes a shielding member for shielding a wearer's mouth and nose, and has air outlet with air-outlet valve and air inlets with air-inlet valves. The mask is characterized in a guide structure and a limiting structure provided between the main body and the front cover. The guide structure includes corresponding slide rail and slide channel capable of guiding the front cover to move along a linear path parallel to a longitudinal section of the air outlet to assemble to the main body and cover the air-outlet valve. The limiting structure includes corresponding male and female fasteners that are detachably engaged with each other when the front cover is assembled to the main body, preventing the front cover from moving in an opposite direction on the linear path to separate from the main body.
