Hollow Cylinder Holder for Breathing Apparatus Valves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for breathing apparatus demand valves with different connections are difficult to manufacture and do not ensure a secure, easy, and detachable connection, leading to potential damage or soiling when exchanging valves with different connections.
Innovation Solution
A hollow cylindrical holding device with internal threads for secure attachment of demand valves using 1.5 threads and a circumferential locking edge for plug-in connections, allowing secure and easy attachment and detachment of various demand valves, including adapters for non-standard connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a soft, elastic molded part with multiple holding elements is used to accommodate different demand valve connections, then the holding device can accept various standardized connections, but the secure fixation of the demand valve is not guaranteed and the production becomes complex
Solution Approach 1:
The holding device incorporates different types of holding elements (screw holding elements with threaded bores, plug-in holding elements with locking edges, and clamp holding elements with resilient clamping elements) at different locations within the same device. Each holding element is specifically designed to match particular connection types, providing localized optimal fixation for each connection standard while maintaining overall versatility.
Solution Approach 2:
The holding device is divided into multiple independent holding elements, each capable of securing a specific type of demand valve connection. This segmentation allows each element to be optimized for its specific function (screwing, plugging, or clamping) while collectively providing universal compatibility across different connection standards.
2Reliability
If multiple different holding devices are used for different connections, then each connection type can be securely held, but the device complexity increases and exchange becomes difficult
Solution Approach 1:
The holding device is designed as a universal multi-functional unit that can securely hold demand valves with different connection types (screw connections via threaded bores, plug-in connections via locking edges, and clamp connections via resilient clamping elements) within a single device structure, eliminating the need for multiple separate holding devices.
Solution Approach 2:
Multiple specialized holding elements (screw holding elements, plug-in holding elements, and clamp holding elements) are merged into a single integrated holding device structure, allowing one device to perform the functions of what would otherwise require multiple separate devices for different connection types.
3Speed
If demand valves are kept on standby for quick use, then user response time is reduced, but the risk of accidental activation and damage increases
Solution Approach 1:
The demand valve is pre-positioned in a ready state within the holding device, secured in a standby position where it is immediately accessible but protected from accidental activation. The controlled release mechanisms ensure the valve can be quickly deployed when needed while preventing unintended activation during storage or transport.
Solution Approach 2:
The holding device acts as an intermediary between the demand valve and the user environment, providing a controlled interface that allows quick access while preventing accidental activation. The specific release mechanisms (threaded, locking edge, or clamping) require intentional user action to release, serving as a protective barrier against unintended deployment.

AI summary
A holder for temporarily holding the automatic lung device of breathing apparatus comprises a hollow cylinder (1) made of stiff material, with internal diameter sections which decrease in size step by step and into which there is formed an inner thread (4a, 5a) with a small number of thread turns corresponding to the standardized outer thread of the automatic lung devices. The external diameter of the hollow cylinder is of a size, and designed with a locking edge (3a) extending about the circumference, such that an automatic lung device with a standardized plug connector can also be secured. Thus, when not in use, automatic lung devices with different standardized connectors are held quickly, safely and releasably.
