Frameless Facial Shield with Gasket Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facial protection solutions fail to provide a watertight seal during showering or hair washing, risking damage to makeup, eyelash extensions, and exposing sensitive areas to hazardous substances like shampoo and hair chemicals.
Innovation Solution
A frameless, adjustable facial shield with a gasket strip and hook-and-loop fasteners creates a water-tight seal across the forehead and hairline, using flexible clear plastic material and a rubber gasket strip to deflect water and chemicals away from the face, allowing for easy application and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a frameless shield is used, then the device complexity is reduced and it is easier to manufacture, but it becomes difficult to provide a watertight seal
Solution Approach 1:
The patent uses a flexible gasket strip with multiple protruding ridges that contacts the skin to create a watertight seal. This flexible membrane approach allows the frameless shield to achieve reliable sealing without rigid structural elements, resolving the contradiction between simplicity and sealing effectiveness.
2Reliability
If a gasket strip with multiple protruding ridges is used, then the watertight seal is improved, but the device complexity increases
Solution Approach 1:
The gasket strip features multiple protruding ridges at specific locations to create sealing contact points with the skin. This localized structural enhancement provides effective sealing only where needed (at the interface between shield and skin) while keeping the rest of the simple frameless shield structure uncomplicated.
3Object-affected harmful factors
If the shield covers the entire facial area, then the protection against hazardous substances is improved, but the ease of operation is reduced
Solution Approach 1:
The shield is designed as a separate component that can be independently applied to the face area, distinct from the headband. This segmentation allows the shield to be easily applied and removed over the facial area while the headband remains as a separate securing element, improving ease of operation despite comprehensive coverage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents water and hazardous substances from reaching the face, maintaining makeup integrity and ensuring proper healing of surgical sites while allowing for comfortable and convenient showering and shampooing.
Implementation Method 1
The gasket strip provides a substantially water-tight and releasable seal that separates a face portion of the user from a forehead portion of the user
Data Source
AI summary
A frameless adjustable facial shield can have a shield connected to a headband with the headband having a gasket strip with multiple protruding ridges configured to continuously contact the skin of a user. The gasket strip can provide a substantially water-tight and releasable seal that separates a face portion of the user from a forehead portion of the user while the face portion is covered by the shield.
