Flat Part Holder Clip Design for Switchgear Cabinet Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat part holders for control cabinets are complex and expensive to manufacture and use, requiring multiple components and tools for assembly, making them cumbersome and costly.
Innovation Solution
A simplified flat part holder design featuring a clasp-like structure made from a single piece of sheet metal or conductive plastic, with a threaded passage and curved clamping section, allowing for tool-free pre-assembly by clipping into frame recesses and providing a firm connection through a screw-in mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional flat part holder with multiple components is used, then the fastening function is reliable, but the manufacturing cost and device complexity increase
Solution Approach 1:
The patent combines multiple separate components (clip body, fastening element, and bracing mechanism) into a single integrated flat part holder. The holder features a unified structure where the plug-in sections, threaded passage, and clamping mechanism are all part of one component, eliminating the need for separate parts while maintaining the reliable fastening function.
Solution Approach 2:
The flat part holder is designed with distinct functional sections: plug-in sections for engagement with frame recesses, a threaded passage for screw fastening, and a curved clamping section for bracing. This segmentation of functions within a unified structure allows each section to perform its specific role while contributing to the overall simplified design.
2Reliability
If a traditional flat part holder requiring pre-assembly on the frame is used, then the fastening is secure, but the assembly time and ease of operation deteriorate
Solution Approach 1:
The flat part holder is designed to be pre-assembled on the frame by simply inserting the plug-in sections into recesses without tools. The curved clamping section is pre-configured to engage with the frame, creating a preliminary secure connection that prepares the holder for the final fastening step when the flat part is attached.
Solution Approach 2:
The plug-in sections are designed to automatically engage with the frame recesses through a simple insertion motion, and the curved clamping section self-adjusts to provide bracing. This self-service mechanism eliminates the need for tools or complex assembly procedures while ensuring secure fastening.
3Reliability
If multiple flat part holders are used to fasten a flat part, then the fastening coverage is sufficient, but the quantity of components and manufacturing cost increase
Solution Approach 1:
The flat part holder is designed as a universal component that can be used for various fastening applications on different frames. The plug-in sections can engage with standard frame recesses, and the adjustable clamping mechanism adapts to different flat part sizes and configurations, allowing a single holder design to replace multiple specialized components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design reduces production costs, simplifies the assembly process, and ensures a secure attachment of flat parts to the cabinet frame without the need for multiple components or tools, facilitating easy installation and maintaining structural integrity.
Implementation Method 1
the curved clamping section can have at least one material recess, so that the flat part holder has a lower bending moment in the region of the clamping section compared to the other sections of the flat part holder. As a result, the deformation of the flat part holder can be regulated during the pretensioning of the flat part holder by screwing a screw into the threaded passage.

AI summary
The invention relates to a panel holder (1) for fastening a panel (100) to a housing frame (200) of a switchgear cabinet (300), characterized in that the panel holder (1) is an open clip, which has two free push-in portions (2, 3), which can be braced against one another for engagement in a recess (201) of a housing frame (200), wherein the push-in portions (2, 3) are connected to one another by means of a fastening flange (5) for a panel (100), said flange having a threaded passage (4), in particular a threaded bore, and wherein the fastening flange (5) is arranged at a distance from one of the push-in portions (2, 3) and the threaded passage (4) is arranged in alignment with this push-in portion (2), such that a screw (400) screwed in through the threaded passage (4) impinges on the push-in portion (2) aligned with the threaded passage (4) and thus braces the push-in portions (2, 3) against one another. The invention further relates to a corresponding switchgear cabinet.
