Air-Conditioning Cover Hook Mounting for Sealed Cabinet Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing covers for air-conditioning devices in switchgear cabinets are complex to mount and dismount, require significant space, and do not provide adequate sealing against splash water and directed water jets, despite using hook elements and seals.
Innovation Solution
A cover design with a holder directly connected to the cladding element, featuring receiving profiles with abutment sections and vertical hook elements that allow for stable mounting and dismounting with minimal space, using bent profiled sections and sealing elements for enhanced sealing, and a U-shaped support with legs for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixing screws and nuts are used to attach the cover housing to the cladding element, then the mounting is secure, but the mounting process becomes very elaborate and requires multiple persons
Solution Approach 1:
The mounting system is segmented into a holder with hook elements attached to the cladding element and a cover housing with corresponding hook receptacles. This segmentation allows the cover housing to be independently suspended from the cladding element without requiring multiple persons to hold components during assembly.
Solution Approach 2:
Hook elements and hook receptacles serve as intermediary components that mediate the connection between the cover housing and the cladding element. These intermediaries enable secure attachment while simplifying the mounting process to a single-person operation where the cover housing can be easily hung onto the holder.
2Reliability
If guides are used to suspend the cover housing from the cladding element, then the mounting is stable, but significant space above the guides is required
Solution Approach 1:
Instead of having the cover housing slide onto guides from above (requiring significant vertical space), the design inverts the approach by having hook elements protrude from the cladding element and the cover housing hang onto them from below. This inversion eliminates the need for significant vertical clearance during mounting while maintaining stable attachment.
3Object-affected harmful factors
If a seal is compressed by locking screws to achieve impermeability, then the sealing is effective, but the device complexity increases
Solution Approach 1:
The seal achieves compression and sealing effectiveness automatically through the gravitational suspension of the cover housing onto the holder. As the cover housing is hung onto the hook elements, the seal is self-compressed without requiring additional locking screws or complex fastening mechanisms, thereby maintaining simplicity while ensuring impermeability.
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 solution enables easy handling and mounting/dismounting with low space requirements, provides effective sealing against splash water and strong water jets, and ensures stable fitting and positioning of the air-conditioning device.
Implementation Method 1
the cover housing can be suspended by hook receptacles in the direction of gravity
Implementation Method 2
a sealing element which at least partly protrudes towards the cladding element is compressed between the cover housing and the cladding element

AI summary
The invention relates to a cover for at least one air-conditioning device arranged on a cladding element, in particular of a switchgear cabinet. The cover has a cover housing having a front wall and side parts connected thereto. The side parts keep the front wall at a distance from the cladding element. At least one holder for the cover housing is fitted to the cladding element. According to the invention, the holder comprises vertical hook elements into which the cover housing can be suspended by hook receptacles in the direction of gravity.
