Control Cabinet Wall Joint Frame for Sealed Cable Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control cabinet designs face challenges in mechanically adjoining and sealing adjacent wall segments while ensuring structural integrity and cable protection.
Innovation Solution
A control cabinet configuration featuring elongated, plate-shaped wall segments with box-shaped or U-shaped frames that protrude beyond the gaps between segments, incorporating grommets and guide rails for secure assembly and sealing, with the frames extending beyond the wall segments to provide additional stability and coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a U-shaped frame is used to cover the cutout in wall segments, then the assembly is simpler and allows cable access, but the mechanical reliability and structural strength at the joint between adjacent wall segments is insufficient
Solution Approach 1:
The frame is divided into two separate U-shaped partial frames that are inserted into opposite cutouts of adjacent wall segments. This segmentation allows each partial frame to be independently positioned and secured, providing distributed mechanical support at the joint while maintaining ease of assembly. The separation enables cables to pass through grommets in each partial frame independently.
Solution Approach 2:
The U-shaped partial frames are nested within the wall segment structure by inserting them into cutouts that are formed as recesses in the wall segments. This nesting arrangement allows the partial frames to be securely held in position by the wall segments themselves, providing mechanical support while maintaining a compact integrated structure.
2Stability of the object's composition
If the frame protrudes beyond the gap between wall segments, then mechanical support and stability are improved, but the complexity of the structure increases
Solution Approach 1:
The U-shaped partial frames serve multiple functions simultaneously: they provide mechanical support at the joint, act as structural reinforcement, offer cable routing pathways through integrated grommets, and create sealing surfaces. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in structural complexity despite the protruding configuration.
Solution Approach 2:
The partial frames extend in the longitudinal dimension beyond the gap between wall segments, creating a protruding configuration that provides mechanical support. This dimensional extension is achieved through the natural geometry of the U-shaped profiles that are inserted into the wall segments and extend outward, providing stability without requiring complex multi-dimensional structures.
3Reliability
If the wall segment extends far beyond adjacent wall segments to cover gaps, then sealing effectiveness is improved, but the quantity of material and weight increase
Solution Approach 1:
The U-shaped partial frames act as intermediary elements that are positioned at the joints between wall segments to provide sealing and mechanical support. Rather than extending the wall segments themselves far beyond the joints, the partial frames serve as mediating components that fill the gap coverage function, thereby reducing the material quantity required in the wall segments while maintaining sealing effectiveness.
Solution Approach 2:
The wall segments are designed with localized cutouts and the partial frames provide localized reinforcement and sealing at the joint regions. This local quality approach concentrates the sealing and support functions at specific critical locations rather than requiring extensive material extension throughout the entire wall segment length, thereby reducing overall material quantity while maintaining reliability at critical joints.

AI summary
A control cabinet includes at least two plate shaped elongated wall segments. At least one wall segment features at least one open-edged cutout. Edges of adjacent wall segments facing each other, adjoin each other, forming a seal. Each cutout is covered by a frame. The frame includes a plurality of grommets to accommodate cables. In an assembled state each frame is enclosed and each frame protrudes beyond the butt joint between adjacent wall segments, covering same.
