Switch Motor Drive Latching Device Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical switches with motor drives require complex and tool-dependent assembly and disassembly processes, leading to inefficiencies and potential for unintentional or unauthorized removal.
Innovation Solution
Incorporation of a latching device with a spring-loaded control element and blocking mechanism that allows for simple actuation from the outside, enabling quick assembly and disassembly without specialized tools, and includes a blocking device to prevent unauthorized removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a motor drive is mounted on the switch housing using conventional methods, then the motor drive can be securely attached, but the assembly and disassembly process becomes complex and requires special tools
Solution Approach 1:
The latching device is divided into separate functional elements: latching elements on the motor drive, corresponding latching elements on the switch housing, and a control element. This segmentation allows the motor drive to be easily attached and detached by simply actuating the control element, eliminating the need for complex assembly procedures and special tools.
2Ease of operation
If the latching device can be easily actuated from the outside, then assembly and disassembly become simple and quick, but the risk of unintentional or unauthorized removal increases
Solution Approach 1:
The control element is designed to be spring-loaded, automatically transitioning between a first control position (allowing latching/unlatching) and a second control position (blocking unlatching). This dynamic mechanism ensures that the motor drive can be easily removed when authorized (control element in first position) while preventing unintentional or unauthorized removal when the control element is in the second position, thus resolving the contradiction between ease of operation and reliability.
3Reliability
If a blocking device is added to prevent unauthorized removal, then security is improved, but the device complexity increases
Solution Approach 1:
The blocking function is merged into the existing control element of the latching device. The control element serves dual purposes: it controls the latching/unlatching operation and simultaneously provides the blocking function to prevent unauthorized removal. By combining these functions into a single integrated component rather than adding a separate blocking device, the patent improves security while minimizing the increase in device complexity.

AI summary
The switch (10) comprises a motor drive (30) that is located in switch housing (20) through a latching device (40). The motor drive is disassembled by unlatching the latching device. The latching device is provided with user-side operable locking unit (70) which is held on the switch housing in a latched position of the motor drive and the locking unit is released in an unlatched position. An independent claim is included for a method for assembling and disassembling motor drive with respect to switch housing.
