Outdoor Cabinet Top Structure Bending Plate Hoisting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing outdoor integrated cabinets have a weak top structure due to flat top beams, limiting the flexibility and capacity for hoisting, and their design restricts the volume, making it difficult to manufacture larger units.
Innovation Solution
The top structure is enhanced by using bending plates for the top beams, with locating breaches and protruding portions for secure connection, and incorporating self-clamping and self-adhesive sealing strips for sealing, along with a hoisting member like a corner piece for improved strength and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If flat top beams are used in the outdoor cabinet, then the manufacturing process is simple, but the strength of the top structure is low and hoisting flexibility is poor
Solution Approach 1:
The patent applies curvature by transforming the flat top beam into a bending plate with arc-shaped cross-section. This curved structure increases the moment of inertia and section modulus, thereby significantly improving the strength and stiffness of the top structure while maintaining manufacturing feasibility through standard bending processes
Solution Approach 2:
The patent segments the top structure into multiple bending plate components connected by locating breaches and protruding portions. This segmentation allows for modular assembly, facilitating installation and maintenance while the collective arrangement of multiple segments achieves the required overall strength
2Volume of stationary object
If the outdoor cabinet volume is increased, then the functionality and capacity are improved, but the processing level and overall strength become insufficient
Solution Approach 1:
The curved bending plate structure inherently provides higher strength-to-weight ratio compared to flat plates, enabling the cabinet to achieve larger volume while maintaining sufficient structural strength. The arc-shaped cross-section distributes stresses more effectively across the structure
Solution Approach 2:
By segmenting the cabinet into modular components that can be assembled from standardized bending plates, the design enables scalable volume expansion. Multiple units can be combined or individual components can be enlarged while maintaining the proven structural integrity of the bending plate configuration
3Area of stationary object
If multiple top beams are connected, then the coverage area is increased, but the positioning accuracy and assembly precision are difficult to ensure
Solution Approach 1:
The locating protruding portions are pre-formed on the bending plates during manufacturing, establishing precise positioning features before assembly. This preliminary action ensures that when multiple top beams are connected, their relative positions are automatically aligned with high precision, eliminating the need for complex measurement and adjustment during installation

AI summary
An outdoor cabinet and a top structure thereof are provided. The top structure of the outdoor cabinet includes a top beam, wherein the top beam is a bending plate; the number of the top beams is at least two, one of two connected top beams is provided with a first locating breach, and the other is provided with a first protruding portion in cooperation with the first locating breach for locating. Compared with that the top beam in the conventional art is a flat plate, the top structure of the outdoor cabinet provided effectively improves the strength of the top beam by designing the top beam to be the bending plate, which improves the strength of the overall top structure, reduces the influence on the hoisting of the outdoor cabinet, and improves the flexibility of the hoisting of the outdoor cabinet.
