Enclosure Frame Structure with T-Slot Channels and Segmented Backbone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame structures for electronic equipment enclosures lack both strength and adaptability, often exhibiting structural weaknesses in joints or interconnections due to the need for high adjustability, and do not support a wide range of features for various positioning and adjustment needs.
Innovation Solution
A frame structure with a pair of front and rear vertical members, horizontal side-to-side members, and front-to-back members, featuring T-slot channels and recessed grooves with mounting apertures, allowing for adjustable mounting of accessories and panels, and an adjustment assembly with a leveling foot mechanism for height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If frame structures use traditional open cross-section sheet metal members, then ease of manufacture is improved, but structural strength deteriorates
Solution Approach 1:
The frame member is divided into a backbone portion and flange portions that are separately formed and then joined together. The backbone portion provides the primary structural strength while the flange portions add functionality and additional strength, resolving the contradiction between ease of manufacture and structural strength.
Solution Approach 2:
The frame member combines different structural elements (backbone and flanges) into a composite structure that achieves both high strength and ease of manufacture. The composite design allows each portion to be optimized independently while working together to provide superior overall performance.
2Strength
If frame structures use tubular steel members with closed profiles, then structural strength is improved, but adaptability for various mounting positions deteriorates
Solution Approach 1:
The frame member is segmented into a closed-profile backbone for strength and separate flange portions with T-slot channels for adaptability. This segmentation allows the structural backbone to maintain closed-profile strength while the flanges provide versatile mounting options through T-slot channels and mounting apertures.
Solution Approach 2:
The flange portions serve multiple functions: they provide T-slot channels for adjustable mounting positions, include mounting apertures for secure attachment, and extend the functional capabilities of the strong closed-profile backbone, achieving both strength and universality.
3Adaptability or versatility
If frame structures increase adjustability features, then adaptability is improved, but structural strength in joints deteriorates
Solution Approach 1:
The frame member separates the structural backbone from the adjustable mounting features (flanges with T-slots and apertures). This segmentation ensures that the backbone maintains closed-profile strength while the flanges provide the necessary adjustability, preventing the weakening of joints that occurs when adjustability features are added to simple open-section members.
Solution Approach 2:
The composite structure of backbone and flanges allows the joint design to incorporate both strong connection points (at the backbone) and flexible mounting options (at the flanges), maintaining joint strength while providing adaptability.
4Adaptability or versatility
If frame members use extrusion process for custom shapes, then adaptability for mounting accessories is improved, but manufacturing complexity increases
Solution Approach 1:
The frame member is segmented into a simple extruded backbone and separately formed flange portions. The backbone can be produced by standard extrusion processes, while the flanges are formed separately and attached, reducing overall manufacturing complexity compared to creating a single complex custom-extruded shape.
Solution Approach 2:
The flange portions with T-slot channels provide universal mounting capabilities for various accessories and positioning requirements, achieving adaptability through modular components rather than complex custom extrusions.

AI summary
A frame structure for an electronic equipment enclosure includes a pair of front vertical frame members, a pair of rear vertical frame members, and a plurality of horizontal frame members. The plurality of horizontal frame members includes a pair of front horizontal side-to-side members that connect respective upper ends of the pair of front vertical frame members and respective lower ends of the pair of front vertical frame members, thereby forming a front frame; a pair of rear horizontal side-to-side members that connect respective upper ends of the pair of rear vertical frame members and respective lower ends of the pair of rear vertical frame members, thereby forming a rear frame; and at least four horizontal front-to-back members that connect the front frame and the rear frame. At least one of the front vertical frame members and the rear vertical frame members includes a closed profile and a vertical channel extending a length thereof for providing access to an adjustment assembly of a leveling foot, the adjustment assembly being positioned within the vertical channel and outside of the closed profile. At least one of the horizontal side-to-side members and the horizontal front-to-back members is a structural member having a closed profile that includes at least one T-slot channel and at least one recessed groove extending a length thereof, the at least one recessed groove including a row of mounting apertures arranged therein.
