DIN Rail Mount with Release Button for Easy Locking and Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric devices attached to DIN rails face difficulties in detachment due to the challenging mechanism of disengaging the engagement section from the engagement groove, making the process less workable.
Innovation Solution
A device with a housing that includes a rail mount, a locking member, and a release button, where the locking member can be moved from a locking to a release position by pressing the release button, allowing easy attachment and detachment from the DIN rail by aligning the rail with the rail mount and using the locking member to secure or release the engagement flange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the engagement section is forced out of the engagement groove to detach the device, then the device can be removed from the rail, but the operation becomes difficult when the protruding part is close to the wall
Solution Approach 1:
The patent introduces a release button as an intermediary component that the user interacts with instead of directly manipulating the movable body. The release button is connected to the movable body through a linkage mechanism, allowing the user to apply force to the movable body indirectly. This solves the problem of difficult operation when the protruding part is close to the wall, as the release button can be positioned away from the wall to provide adequate operating space.
2Ease of operation
If the movable body is pinched to move it for detachment, then the engagement section can be disengaged, but applying force becomes difficult when close to the wall
Solution Approach 1:
The release button serves as a mediator that amplifies the user's input force and transmits it to the movable body through a linkage mechanism. This allows the user to apply force more easily to the release button (which is positioned away from the wall) rather than directly to the movable body (which is close to the wall), reducing the time and effort required for detachment.
Solution Approach 2:
The patent changes the dimension of user interaction by moving the operation point from the rear surface of the device (close to the wall) to the front surface (away from the wall) through the release button. This spatial repositioning allows the user to apply force from a more accessible location, improving ease of operation and reducing the time required for detachment.
3Ease of manufacture
If the engagement section is forced out of the engagement groove, then detachment is achieved, but the workability is reduced
Solution Approach 1:
The release button acts as an intermediary that provides a convenient interface for the user to initiate the disengagement process. By pressing the release button, the user triggers the linkage mechanism to move the movable body and disengage the engagement section from the engagement groove. This improves workability by providing a clear, easy-to-operate control mechanism rather than requiring direct manipulation of the engagement components.

AI summary
A device includes a housing including a rail mount and a stopper to lock an engagement flange (RAb) on a DIN rail (RA) with the rail mount receiving the DIN rail (RA). A locking member is at a locking position to lock an engagement flange (RAb) on the DIN rail (RA) and at a release position to unlock the engagement flange (RAb) with the rail mount receiving the DIN rail (RA). A release button including a pressing portion to be pressed by a user is located in the housing with the pressing portion exposed outside the housing. An arm moves the locking member from the locking position to the release position in response to movement of the release button from a standby position to a pressed position deeper in the housing than the standby position.
