Automatic Lock Merged Control Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic locks require operator intervention on both the strike plate and lock case for deactivating the automatic function, leading to a risk of malfunctions due to potential forgotten steps.
Innovation Solution
A movable control element is integrated into the locking plate, coupled with the actuating element, allowing for simultaneous control and activation, simplifying the operation by requiring only a single manual action to switch between day and night functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate control elements are used for the bolt and counter-locking part, then each component can be controlled independently, but the operation becomes complex and error-prone requiring multiple manual interventions
Solution Approach 1:
The patent combines the control of the bolt and counter-locking part into a single integrated control element. This merging eliminates the need for separate manual interventions and reduces operational complexity while maintaining the ability to control both components independently through the unified mechanism.
Solution Approach 2:
The single control element serves multiple functions by simultaneously controlling both the bolt and counter-locking part. This multi-functionality allows one operating element to perform what previously required multiple separate actions, reducing errors and simplifying the user interface.
2Adaptability or versatility
If multiple separate control interventions are required, then each component can be adjusted independently, but the risk of malfunctions increases due to forgotten steps
Solution Approach 1:
By merging the control functions into a single integrated control element, the patent ensures that both the bolt and counter-locking part are controlled together in one action. This eliminates the risk of forgotten steps that occurs with multiple separate controls, while still allowing independent adjustment of each component through the unified mechanism.
Solution Approach 2:
The integrated control element provides immediate feedback that both components have been properly controlled together. This feedback mechanism ensures that no steps are forgotten and maintains reliability by confirming that both the bolt and counter-locking part are in the correct positions after a single intervention.
3Ease of manufacture
If control elements are distributed on multiple components, then detailed control is possible, but the structure becomes more complex
Solution Approach 1:
The patent merges multiple control elements into a single integrated control element, reducing the number of separate components and simplifying the overall structure. This consolidation maintains the ability to control both the bolt and counter-locking part with precision while significantly reducing structural complexity and the number of parts that need to be manufactured and assembled.

AI summary
The automatic lock (3) has an actuating element provided for selectively blocking or releasing movement of closing portion. The switch (13) is provided for detecting position of lock case (7) provided opposite to locking plate (10). A trigger element (14) is located in the locking plate for actuating switch. The switch is controllable in position of the trigger element while switch is not controllable in the other position of the trigger element. The actuating unit is provided for actuation of the trigger element and the actuating element coupled with one another.
