Switchboard Built-in Unit Fastening with Slide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fastening built-in units on switchboards often require a second person, especially for larger switchboards, due to the complexity and need for additional support during the fitting process.
Innovation Solution
A sealed fastening system utilizing holders with holding lugs and a slide mechanism that engages with depressions on the built-in unit, combined with clamping elements that press against the switchboard rear side for secure fixation and sealing, allowing a single person to fasten the unit by using screws and an elastic material for sealing purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening methods with clamps and screws are used, then the built-in unit can be securely fastened on the switchboard, but a second person is required during fitting, increasing operational complexity
Solution Approach 1:
The holder is pre-assembled with the mount and slide mechanism before installation. The slide is positioned to engage with the built-in unit's features, and the mount is pre-configured to receive the holder. This preliminary preparation allows a single person to complete the fastening operation without requiring assistance during the actual installation process.
Solution Approach 2:
The slide acts as an intermediary element between the holder and the built-in unit. It engages with specific features on the built-in unit and transmits the fastening force, enabling precise positioning and secure attachment. The slide mechanism allows the holder to interact with the built-in unit in a controlled manner, facilitating single-person operation.
2Reliability
If multiple fastening components are used, then the built-in unit can be securely fixed, but the device complexity increases
Solution Approach 1:
The holder, mount, and slide mechanism are merged into a single integrated fastening system. The holder is attached to the mount, and the slide is integrated with the holder assembly. This merging reduces the number of separate components and simplifies the overall structure while maintaining secure fixation capability.
Solution Approach 2:
The holder serves multiple functions: it provides structural support, enables positioning, and facilitates fastening. The mount serves dual purposes by providing a mounting surface and supporting the holder. The slide mechanism simultaneously engages with the built-in unit and transmits fastening force. This multi-functionality reduces the need for additional specialized components.
3Reliability
If severe pressing force is applied by clamping elements, then sealing of the through-opening is achieved, but the complexity of the fastening system increases
Solution Approach 1:
The slide mechanism automatically generates the necessary pressing force during the fastening process. As the slide is moved into position and engages with the built-in unit, it naturally applies the required force to the clamping elements. The system self-regulates the pressing force based on the engagement characteristics, eliminating the need for separate force-adjustment mechanisms.
Solution Approach 2:
The clamping elements are designed to dynamically adjust to the engagement conditions. The slide mechanism provides a progressive engagement that naturally builds the required pressing force. The elastic material between the collar and switchboard front side dynamically adapts to the applied force, providing sealing without requiring excessive static pressure.

AI summary
At least one embodiment of the invention relates to the fastening and fitting of a built-in unit on a switchboard, which has a through-opening for this purpose, a collar, which is arranged on the built-in, limiting the action of plugging through the built-in unit, and at least one fixing and clamping device ensuring that the built-in unit is pressed correspondingly against the switchboard. In order to specify simple fastening including fitting which can be carried out by a single person, at least one embodiment of the invention proposes that holders arranged on both sides of the built-in unit and having mounts with holding lugs, which are arranged thereon and engage in corresponding depressions and/or apertures of the built-in unit, are provided, that each mount has a web, on which a slide, which latches in stepwise, can be moved toward the switchboard rear side, as a result of which it presses the holding lugs against the depressions and/or apertures and thus fixes the built-in unit in the through-opening first in the intended position, and that sealing of the through-opening takes place by means of clamping elements, which press against the switchboard rear side.
