Universal Door Lock with Selective Actuator Deactivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door locks lack flexibility in terms of function and configuration, leading to complex logistics in supply, transport, and storage, and are often cumbersome to assemble and install.
Innovation Solution
A lock design featuring a box-like body with a rear wall-mounted latch or bolt and a front cover supporting both a command cylinder and button, with deactivation means allowing the button to switch between operational and locked states, enabling various functional configurations and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lock variants are produced to accommodate different functions (left/right hand opening, different entry positions), then functional versatility is improved, but device complexity and logistics complexity increase
Solution Approach 1:
The lock body is designed with a universal structure that can accommodate different functions (left/right hand opening, different entry positions) through configurable components rather than requiring separate variants. The command cylinder and command button can be positioned at different locations on the same lock body, and the push handle can be configured for different opening directions, all within a single standardized lock body design.
Solution Approach 2:
The lock system incorporates adjustable and reconfigurable elements that allow the same physical lock body to adapt to different functional requirements. The deactivation means enable dynamic switching between operational and deactivated states for different actuating elements, allowing the lock to be configured for various use cases without physical modification to the basic structure.
2Adaptability or versatility
If multiple lock variants are produced to accommodate different functions, then functional versatility is improved, but ease of manufacture deteriorates
Solution Approach 1:
The lock body is designed with a universal structure that can accommodate different functions (left/right hand opening, different entry positions) through configurable components rather than requiring separate variants. The command cylinder and command button can be positioned at different locations on the same lock body, and the push handle can be configured for different opening directions, all within a single standardized lock body design.
3Adaptability or versatility
If deactivation means are added to switch between operational and locked states, then adaptability is improved, but device complexity increases
Solution Approach 1:
The deactivation means are integrated into the existing structure of the command button and command cylinder mechanisms. The support element of the second actuating element interacts with the support element of the first actuating element to provide deactivation functionality, merging multiple functions into a unified mechanical arrangement rather than adding separate independent mechanisms.

AI summary
The lock (1) to be applied to a wall of a door leaf comprises a box-like body (2), a latch and/or a bolt positioned in the box-like body (2) and extractable from a lateral wall (5) of the box-like body (2), and a closing front cover (6) of the box-like body (2), the closing cover (6) supporting a command cylinder (7) of a first actuating element (12) of a retraction mechanism (13) of the latch and/or bolt, and a command button (8) of a second actuating element (14) of the retraction mechanism (13) of the latch and/or bolt, there also being provided means (15) of selective deactivation of the command cylinder (7) or of the command button (8).
