Control Cabinet Base Mounting via Pre-assembled Connecting Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switch cabinets with dismantled control cabinets face difficulties in attaching a base from the outside, as the available bases are typically designed for internal attachment only, limiting their compatibility with dismantled components.
Innovation Solution
A connecting device with a fastening body and mounting bracket allows for external attachment of the base, featuring orthogonal contact sides and passages for screws, enabling easy mounting without requiring internal access, and includes eyebolts for transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a base is designed for internal attachment only through a base plate of the switch cabinet housing, then the attachment method is simple, but the base cannot be easily mounted on dismantled control cabinets and external mounting is not possible
Solution Approach 1:
The connecting device is divided into multiple independent components: an inner housing corner connector that attaches to the switch cabinet housing, a fastening body that provides the mounting interface, and an outer housing corner connector that offers external attachment points. This segmentation allows the base to be mounted externally on both complete and dismantled control cabinets, resolving the contradiction between simple attachment and adaptability to dismantled components.
Solution Approach 2:
The connecting device serves multiple functions: it provides internal structural support through the inner housing corner connector, offers external mounting capability through the fastening body and outer housing corner connector, and protects edges from dirt. This multi-functionality enables the same device to accommodate both internally-mounted and externally-mounted bases, as well as work with both complete and dismantled control cabinets.
2Adaptability or versatility
If individual parts of a dismantled switch cabinet are used, then the switch cabinet can be transported and reconfigured, but the parts are only suitable to a limited extent for being connected to a base
Solution Approach 1:
The inner housing corner connector is pre-assembled to the switch cabinet housing during manufacturing, with the fastening body and outer housing corner connector already in place. This preliminary action ensures that when the control cabinet is dismantled for transport or reconfiguration, the base connection capability is already prepared and requires no additional assembly, thus maintaining high suitability for base connection without adding operational complexity.
3Ease of operation
If the connecting device has multiple components (inner connector, fastening body, outer connector), then external base mounting is enabled, but the device complexity increases
Solution Approach 1:
The inner housing corner connector, fastening body, and outer housing corner connector are merged into a single pre-assembled connecting device unit. This combining approach allows the multiple components to function together as one integrated solution during manufacturing, simplifying the assembly process and reducing the number of separate assembly operations required, thereby offsetting the increased component count with improved manufacturing efficiency.
