Surgical Garment Face Shield with Integrated Capacitive Controls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal protection systems for healthcare providers in medical and surgical settings face challenges in accessing control buttons without compromising sterility, leading to potential contamination and discomfort due to the need for less breathable materials to prevent fluid penetration.
Innovation Solution
The personal protection system incorporates control buttons mounted on the face shield of the helmet, with conductive traces and magnets allowing for easy access and operation without touching the garment, ensuring sterility and reducing material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control buttons are mounted on the garment, then accessibility is improved, but sterility is compromised due to potential contamination
Solution Approach 1:
The control system is segmented into two separate locations: buttons on the helmet (non-sterile zone) and corresponding sensors on the face shield (sterile zone). This allows the healthcare provider to press buttons on the helmet while the face shield sensors detect the input, maintaining sterility while ensuring accessibility.
Solution Approach 2:
The face shield acts as an intermediary between the sterile environment and the non-sterile control buttons. The conductive traces and capacitive sensors on the face shield detect button presses without requiring direct contact between the provider's hand and the garment, preserving sterility while enabling control.
2Reliability
If less breathable materials are used to prevent fluid penetration, then protection is improved, but comfort deteriorates
Solution Approach 1:
The face shield is constructed as a composite structure with multiple layers including breathable fabric and fluid-resistant coating or membrane. This allows the garment to maintain fluid barrier protection while permitting vapor transmission for improved comfort and breathability.
Solution Approach 2:
The material properties are optimized by changing parameters such as pore size, coating density, and layer composition to achieve the optimal balance between fluid resistance and breathability, allowing moisture vapor to pass through while blocking liquid fluids.
3Reliability
If buttons are mounted on the face shield, then sterility is maintained, but manufacturing complexity increases due to conductive traces and magnet integration
Solution Approach 1:
The button functionality is merged directly into the face shield structure by integrating conductive traces and capacitive sensors into the existing face shield material or coating, eliminating the need for separate button components and reducing manufacturing complexity.
Solution Approach 2:
The face shield serves multiple functions: it provides fluid protection, maintains sterility, enables control input detection, and integrates the control interface directly into its structure, eliminating the need for separate control components and simplifying the overall system.
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
This design enhances accessibility and reduces the risk of contamination by allowing healthcare providers to control system functions without compromising sterility, while also minimizing material costs and discomfort associated with less breathable materials.
Implementation Method 1
The buttons are electrically connected to the controller through conductors that extend from the buttons to fastening features that engage complementary fastening features on the helmet. The buttons may be actuated by a gloved finger without breaking sterility.
Implementation Method 2
The fastening features may include magnets that are attracted to one another. The magnets may also provide an electrical connection between the face shield and the helmet.
