Filter Adapter Sealing Protective Suit Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing respiratory protective devices face challenges when used in protective suits, as they either require frequent reprocessing due to contamination or necessitate complex interfaces for ambient air sampling.
Innovation Solution
A filter adapter that can be connected to a filter device and holds a filter unit, featuring a connecting structure, a holding structure, and a contact surface for sealing with a protective suit, allowing for flexible use and reducing the need for different types of filters or devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the filter device is worn outside the protective suit, then the protective suit can be kept compact, but the filter device becomes contaminated by harmful substances and requires frequent reprocessing
Solution Approach 1:
The patent introduces a removable filter adapter as an intermediary component between the protective suit and the filter device. The adapter includes a sealing element that creates a seal with the protective suit, allowing the filter device to be worn outside the suit without contaminating the suit itself. The adapter can be detached and replaced without removing the entire filter device, thus reducing reprocessing frequency while maintaining suit compactness.
2Ease of manufacture
If the filter device is worn inside the protective suit, then reprocessing of the filter device is avoided, but a complex interface is required for ambient air sampling
Solution Approach 1:
The patent divides the interface system into separate functional components: the filter adapter with sealing element for creating the seal, and the breathing connection with sampling port for ambient air intake. This segmentation allows the sampling function to be simplified and integrated into the breathing connection rather than requiring a complex integrated interface, while still avoiding filter device contamination.
3Adaptability or versatility
If different types of filters and filter devices are provided for different purposes, then specific application requirements are met, but device complexity and variety increase
Solution Approach 1:
The patent designs the filter adapter with universal compatibility features: the connecting structure can be connected to various filter devices, the holding structure can hold different filter units, and the sealing element can seal with the protective suit. This multi-functionality allows a single adapter design to serve multiple applications (wearing inside or outside the suit, different filter types) without requiring multiple specialized devices, thus maintaining adaptability while reducing overall system complexity.

AI summary
A filter adapter holds a filter unit and corresponding personal protection equipment. The filter adapter can be connected to a filter device and can thus be used together with a filter device. The filter adapter is suitable for holding a filter unit and can be connected to a filter device. The filter adapter includes: a connecting structure for connection to the filter device, a holding structure for holding the filter unit, and a contact surface for sealing contact with a protective suit.
