Panic Lock Coupling Block for Multi-Function Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panic locks require multiple variants to accommodate different applications, leading to a large number of locks that manufacturers need to stock, and existing designs are complex with many parts, making them difficult to adapt for various functions.
Innovation Solution
A lock mechanism where an actuating element on the panic lever presses a coupling block into a coupling position when the panic lever is closed, simplifying the functional chain between the bolt and the outer nut, and allowing the lock to function as both a DIN right and DIN left lock, with an optional cutting disc for additional functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lock variants are provided to accommodate different applications, then the adaptability to different functions is improved, but the device complexity and number of parts to be stocked increases
Solution Approach 1:
The lock mechanism is designed with a universal coupling block that can be engaged or disengaged based on the panic lever position, allowing the same lock to perform multiple functions (panic lock, passage lock, changeover lock) without requiring multiple variants. The coupling block acts as a universal component that enables different locking behaviors through a single mechanism.
Solution Approach 2:
The coupling block is designed to be dynamically engageable or disengageable based on the panic lever position. When the panic lever is in the closed position, the coupling block is pressed into the engaged position, creating a dynamic adjustment of the functional chain between the bolt and outer nut, allowing the lock to adapt its behavior without physical reconfiguration.
2Adaptability or versatility
If existing lock designs are made complex with many parts to achieve various functions, then the functional versatility is improved, but the ease of manufacture and assembly deteriorates
Solution Approach 1:
The coupling block merges the functions of multiple components into a single element. Instead of having separate mechanisms for different locking functions, the coupling block integrates the functionality to engage or disengage the functional chain between the bolt and outer nut, simplifying the overall structure and reducing the number of parts to be manufactured and assembled.
Solution Approach 2:
The coupling block extracts and isolates the critical function of engaging/disengaging the functional chain from the complex multi-part mechanisms. By taking out this specific function and implementing it through a dedicated coupling block actuated by the panic lever, the design simplifies manufacturing while maintaining functional versatility.
3Ease of operation
If the functional chain between the bolt and outer nut is simplified, then the ease of operation is improved, but the reliability of different locking functions may deteriorate
Solution Approach 1:
The coupling block serves as an intermediary element between the panic lever and the functional chain connecting the bolt and outer nut. It mediates the transmission of motion and force, ensuring that when the panic lever is in the closed position, the coupling block is reliably pressed into the engaged position, maintaining the integrity of the locking function while simplifying the overall operational sequence.
Solution Approach 2:
The coupling block is preliminarily positioned and engaged through the panic lever action before the actual locking or unlocking operation occurs. This preliminary engagement ensures that the functional chain is properly established or disconnected in advance, maintaining reliability while making the subsequent operation simpler and more direct.
