Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Respiratory protection devices require valves that maintain high pressure over extended periods but must be quickly activated in emergency situations, posing a challenge in balancing secure closure and rapid opening under high pressure conditions.
Innovation Solution
A securing device with a torque-applying mechanism, where a handling element and abutment within the housing facilitate the rotation of a securing element from a closed to an open position, utilizing a beveled edge to convert high valve forces into torque, ensuring secure closure and rapid activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high closing forces are applied to maintain pressure over extended storage periods, then pressure maintenance reliability is improved, but the time required to activate the valve in emergency situations increases
Solution Approach 1:
The valve is pre-configured with a securing element that maintains closed position through stored mechanical engagement. The breaking element is pre-positioned within the housing, ready to be activated by an external torque source. This preliminary arrangement allows the valve to maintain secure closure during storage while enabling rapid activation when needed, as the breaking element simply needs to be disengaged rather than requiring gradual force buildup.
Solution Approach 2:
The breaking element acts as an intermediary component between the securing element and the valve closure mechanism. This breaking element can be engaged or disengaged by applying torque through the handling element, providing a mechanical intermediary that transfers rotational force to quickly transition the valve from closed to open position, thereby reducing activation time while maintaining secure closure during storage.
2Reliability
If a securing element is used to maintain valve closure during storage, then pressure maintenance is improved, but the device complexity increases
Solution Approach 1:
The securing element and the valve closure mechanism are merged into a single integrated system. The securing element works together with the valve tappet and closure element as a unified mechanical assembly, where the breaking element engages with the securing element to maintain closure. This merging reduces the number of separate components and simplifies the overall device structure while maintaining reliable pressure containment during storage.
Solution Approach 2:
The securing element serves multiple functions: it maintains valve closure during storage, works with the breaking element to enable rapid activation, and integrates with the existing valve mechanism. The handling element provides universal torque application capability that can be used both for normal operation and emergency activation. This multi-functionality reduces the need for separate dedicated components, thereby reducing device complexity.

AI summary
One embodiment provides a securing device for a valve of a pressurized gas tank of a respiratory protection device, characterized by a securing element (1), which can be moved from a closed position to a flow position, especially an open position, by applying a torque (M), wherein at least one part of a housing (10) serves as an abutment (11) for the securing element when the torque is applied, wherein the valve is closed in the closed position of the securing element and can be brought spontaneously into a flow position after applying a particular torque to the securing element.
