Mask Test Coupling Device for Safe Perforation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mask test methods pose a risk of injury to users due to the need for manual perforation of masks using drills and require cumbersome two-step processes for attaching metal structures, making the process time-consuming and inefficient.
Innovation Solution
A coupling device with a press member and support member that allows for a single, safe operation to perforate and attach the mask test means to a mask, featuring a perforation means integrated into the support member and an upper guide that moves along a lower guide, enabling easy coupling while preventing user injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a drill is used to perforate the mask manually, then the mask can be perforated to mount the metal structure, but the user's hand may be injured by the sharp end of the drill
Solution Approach 1:
The patent introduces a coupling device as an intermediary tool between the user and the mask perforation process. The device includes a pressing member with a pressing portion that contacts the mask, and a supporting member that provides structural support. This intermediary mechanism eliminates direct manual handling of sharp drilling tools, thereby preventing user injury while achieving mask perforation.
Solution Approach 2:
The coupling device is designed to be operated by simply pressing the pressing member against the mask, allowing the device itself to perform the perforation function without requiring the user to manually control sharp drilling tools. The pressing action automatically activates the perforation process through the integrated drill bit, making the system self-serving and safe for user operation.
2Ease of manufacture
If the mask is perforated first and then the metal structure is mounted separately, then the mask test means can be attached, but the process becomes time-consuming and cumbersome
Solution Approach 1:
The coupling device merges the perforation function and the metal structure mounting function into a single integrated operation. The pressing member simultaneously performs both tasks: it presses the mask to create a perforation while also securing the metal structure (cylindrical tube) in place. This combination eliminates the need for separate perforation and mounting steps, significantly reducing processing time and operational complexity.
3Ease of manufacture
If a drill with sharp end is used for perforation, then perforation can be achieved, but the sharp end may pierce the user's hand holding the mask
Solution Approach 1:
The coupling device serves as a safe intermediary mechanism that replaces direct manual drilling operations. The pressing member with its pressing portion contacts the mask in a controlled manner, and the drill bit is integrated into the device structure rather than being manually held. This intermediary design maintains perforation capability while eliminating the safety hazard of sharp drill ends piercing the user's hand.
Solution Approach 2:
The patent replaces the traditional manual drilling mechanical system with a pressed-activation system. Instead of manually guiding a drill, the user simply applies pressure to the pressing member, which mechanically activates the perforation process through the integrated drill bit. This substitution changes the operational mechanism from direct manual control to indirect pressed activation, improving user safety while maintaining perforation effectiveness.
