Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional mechanical trigger systems are used, then the triggering mechanism is simple in structure, but the triggering time is too long to meet explosion suppression requirements
Solution Approach 1:
The patent replaces conventional mechanical trigger systems with an electromagnet-based triggering mechanism. The electromagnet (6) directly acts on the pawl body (5) to release the catch (3) from the pawl flank (4), eliminating complex mechanical linkages and achieving triggering times of less than 10 ms while maintaining system simplicity through direct electromagnetic actuation.
Solution Approach 2:
The patent removes intermediate mechanical components from the trigger system. By having the electromagnet act directly on the pawl body without intermediate rolling elements or complex gear mechanisms, the system achieves both reduced complexity and faster triggering response.
2Speed
If explosives are used for triggering, then the triggering speed is sufficient, but the costs and handling requirements increase significantly
Solution Approach 1:
The patent substitutes explosives with an electromagnet-based mechanical triggering system. The electromagnet (6) can be controlled electronically to achieve the required triggering speed while eliminating all associated costs and handling requirements of explosives, including storage, transport, and safety regulations.
Solution Approach 2:
The electromagnet system can be integrated with the control system to provide automatic triggering based on sensor input, eliminating the need for manual intervention or complex safety procedures associated with explosive handling.
3Device complexity
If the electromagnet acts directly on the pawl body, then the number of moving parts is reduced, but the force required to overcome system friction increases
Solution Approach 1:
The patent employs dynamic design elements including a pivotally mounted pawl body (5) that rotates about a pivot point (7), and a return spring (9) that provides prestress in the engagement direction. These dynamic elements reduce the static friction that would otherwise require excessive electromagnetic force, allowing the electromagnet to effectively move the pawl body with fewer intermediate components.
Solution Approach 2:
The patent optimizes the air gap between the electromagnet and pawl body, and adjusts the pivot point position and return spring prestress to achieve the optimal balance between electromagnetic force requirements and friction overcome capability.

Implementation Method 1
the pawl body can be moved to release the engagement of the catch and the pawl flank and to release the sliding pin by means of at least one electromagnet which acts directly on the pawl body
Implementation Method 2
the pawl body can be prestressed by means of a return spring in the direction of engagement of the catch and pawl flank. The return spring is used not only to reset after a test triggering but also to protect against vibrations and impacts

AI summary
Various aspects of the invention are directed to a triggering device for a quickly triggering extinguishing system for explosion suppression. In some embodiments of the present disclosure, the triggering device may include a pawl body having a pawl flank, a catch, at least one electromagnet to transmit an electromagnetic field, and a sliding pin. The sliding pin triggers an extinguishing system for explosion suppression by movement from a blocking position into a release position. In the blocking position, the sliding pin is pushed against the pawl flank of the pawl body by means of the catch and is held in the blocking position by said pawl flank. The pawl body releases the engagement of the catch and the pawl flank, and thereby releases the sliding pin, in response to the at least one electromagnet exerting the electromagnetic field on the pawl body.
