Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bolt switching contacts for monitoring locking states are prone to inaccurate and unreliable actuation due to high adjustment efforts and tolerances, leading to reduced service life and precision.
Innovation Solution
A bolt switching contact using an elastic spring element to actuate a reed switch, which can be prestressed and converted into a stretched state to directly or indirectly actuate the passive switching element, eliminating the need for additional electronics and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lever-based actuation is used, then the switching element can be actuated, but the adjustment effort is high and reliability is reduced
Solution Approach 1:
The patent replaces the conventional lever-based mechanical actuation system with an elastic spring element that directly actuates the switching element. This substitution eliminates the need for complex adjustment mechanisms and lever systems, thereby reducing adjustment effort while improving actuation reliability through more consistent mechanical engagement.
Solution Approach 2:
The patent changes the actuation mechanism from a lever system with multiple adjustment parameters to an elastic spring element with pre-tensioning. This parameter change simplifies the adjustment process while ensuring more reliable and repeatable actuation of the switching element, as the spring's elastic properties provide consistent force application.
2Duration of action of stationary object
If conventional lever-based actuation is used, then the switching element can be actuated, but the service life is reduced
Solution Approach 1:
The patent replaces the lever-based mechanical system with an elastic spring element that provides more consistent and reliable actuation. This substitution reduces wear and improves the precision of the switching element's actuation, thereby extending its service life while maintaining high reliability.
3Adaptability or versatility
If adjustment options are provided, then tolerances can be compensated, but the device complexity increases
Solution Approach 1:
The patent employs an elastic spring element that automatically compensates for tolerances through its inherent elastic properties. The spring element self-adjusts to accommodate variations in door gap dimensions without requiring external adjustment mechanisms, thereby maintaining adaptability while significantly reducing device complexity.
Solution Approach 2:
The patent uses the elastic properties of the spring element to change the mechanical parameters of the actuation system. This allows the system to automatically adapt to tolerance variations through the spring's ability to deform and recover, eliminating the need for complex adjustment mechanisms while maintaining versatility.

Function Achieved in This Case
This design ensures more reliable, precise, and repeatable actuation of the passive switching element, significantly increasing its service life and eliminating the need for adjustments, while allowing for various locking system configurations.
Implementation Method 1
at least one elastic spring element (14), which can be actuated by the bolt and is pre-tensioned at least substantially in an arc-like manner, in that the elastic spring element (14), when actuated by the bolt to actuate the passive switching element (12), can be transformed from its pre-tensioned state, which is pre-tensioned at least substantially in an arc-like manner, into a state that is at least substantially extended
Implementation Method 2
The passive switching element (12) comprises at least one reed switch (12), which can be actuated directly by the elastic spring element (14) upon each transfer of the elastic spring element (14) to its state that is at least substantially extended

AI summary
A bolt switching contact for monitoring the locking state of a bolt of a lock on a door, window, or the like comprises a passive switching element that can be actuated depending on the locking state of the bolt. The passive switching element can be actuated by at least one elastic spring element, pre-tensioned at least substantially in an arc, which can be actuated by the bolt. This is achieved by the elastic spring element being able to be converted from its pre-tensioned state, at least substantially in an arc, to a state that is at least substantially extended when actuated by the bolt.
