Electromagnetic Pawl Release for Fast Explosion Suppression Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing explosion suppression systems face challenges in achieving rapid triggering times due to high system friction and complexity, which are not effectively addressed by conventional fire extinguishing systems, and pose issues with explosives such as cost, handling, and safety.
Innovation Solution
An electromagnet is applied directly to the latch body to release the engagement of the catch and sliding bolt, minimizing moving parts and system friction, with a return spring for protection against vibrations and impacts, and a pawl body designed for high dynamics and low energy consumption, allowing for quick and reliable triggering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional mechanical triggering systems are used, then the system structure is simple, but the triggering time is too long to achieve rapid explosion suppression
Solution Approach 1:
The patent replaces conventional mechanical triggering systems with an electromagnet-based actuation system. The electromagnet (6) directly actuates the latch body (5), eliminating complex mechanical linkages, intermediate rollers, and multi-stage pawl cascades. This electromagnetic actuation provides rapid response times while maintaining system simplicity through direct action rather than mechanical transmission.
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate components from the triggering mechanism. By using the electromagnet to directly move the latch body, the system removes intermediate rollers, complex pawl cascades, and multiple linkage stages that would increase triggering time and mechanical friction, achieving rapid activation with minimal moving parts.
2Speed
If explosives are used for triggering, then rapid triggering is achieved, but cost, handling, and safety problems arise
Solution Approach 1:
The patent substitutes explosive triggering with an electromagnet-based mechanical actuation system. The electromagnet (6) provides controlled, repeatable, and safe activation without the hazards of explosives. This electromagnetic system achieves the required rapid triggering speed while eliminating all associated safety, handling, storage, and regulatory problems of explosive materials.
3Device complexity
If the latch body is mounted directly on the sliding bolt, then the number of moving parts is reduced, but the release force may be insufficient to overcome system friction
Solution Approach 1:
The patent merges the latch body (5) directly onto the sliding bolt (2), combining functions that might otherwise be separated. This direct mounting reduces the number of moving parts and interfaces, minimizing system friction. The electromagnet (6) provides sufficient force to overcome this friction and rapidly actuate the combined latch-bolt assembly, achieving both simplicity and adequate release force.

AI summary
The invention relates to a triggering device (1) for a quickly triggering extinguishing system (11) for explosion suppression, the triggering device (1) having a sliding pin (2). The triggering of the extinguishing system (11) is brought about by movement of the sliding pin (2) from a blocking position into a release position, and in the blocking position the sliding pin (2) is held against a pawl flank (4) of a pawl body (5) by means of a catch (3) and is held in the blocking position by said pawl flank. In order to release the engagement of the catch (3) and the pawl flank (4) and to release the sliding pin (2), the pawl body (5) can be moved by means of at least one electromagnet (6), which acts directly on the pawl body (5).
