Visor and Face Shield Tab Slot Assembly Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional masks are uncomfortable, difficult to put on and remove, and can become saturated with moisture, leading to reduced effectiveness in preventing viral and bacterial exposure, while alternative visor and face shield devices can be challenging to assemble.
Innovation Solution
A visor and face shield apparatus with separate or integral components that utilize an innovative tab and slot mechanism for easy assembly, featuring adjustable arms and a forehead support member, providing superior protection with improved ease of use and manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional masks are used to prevent exposure to germs and viruses, then protection is provided, but the masks become hot and uncomfortable, difficult to put on and remove, and can become saturated with moisture reducing effectiveness
Solution Approach 1:
The protective device is divided into separate components: a visor portion and a face shield portion that can be assembled together. This segmentation allows the device to be taken apart for easy removal and replacement, solving the problem of difficulty in putting on and removing conventional masks while maintaining protection effectiveness.
2Reliability
If conventional masks are used to prevent exposure to germs and viruses, then protection is provided, but the masks become saturated with moisture causing fogging and reduced effectiveness
Solution Approach 1:
By separating the breathing area from the eye protection area, the device allows moisture from breath to condense on the visor portion without affecting the face shield portion that protects against contaminants. This resolves the moisture saturation and fogging problems that reduce mask effectiveness.
Solution Approach 2:
The visor acts as an intermediary element between the breath and the face shield, allowing moisture to condense on the visor surface rather than on the face shield, thereby preventing fogging and maintaining protection effectiveness.
3Reliability
If visor and face shield devices are used as alternatives to conventional masks, then protection from contaminants is provided, but the devices can be difficult to assemble
Solution Approach 1:
The visor and face shield portions are pre-formed with specific geometric features (tabs and slots) that guide the assembly process. The tabs are pre-positioned on the visor and the slots are pre-formed on the face shield, allowing users to easily assemble the device without complex manufacturing steps.
Solution Approach 2:
The geometric features of the tabs and slots are designed to automatically align and interlock when assembled, with the tabs fitting into the slots through simple insertion movements. This self-aligning mechanism eliminates the need for complex assembly tools or procedures, making the device easy to manufacture and assemble.
