Distribution Box Guiding Rail Orientation for Space Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional distribution boxes waste installation space and restrict layout due to slide rails on the bottom plate, making it inconvenient to install and disassemble electrical accessories.
Innovation Solution
A distribution box design featuring a box body with a cover plate and guiding rails where the open end of the guiding rail faces outward, allowing easy assembly and disassembly of electrical accessories without needing additional installation space, and using a restricting portion to secure the accessory at a vertical height relative to the base plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If slide rails are set on the bottom plate of the distribution box, then electrical accessories can be mounted and fixed, but installation space must be reserved between the open end of each slide rail and the side plates, which wastes receiving space and restricts layout
Solution Approach 1:
The patent repositions the guiding rails from the bottom plate to the side plates of the distribution box. This dimensional relocation allows the open ends of the guiding rails to face the opening of the box body, eliminating the need for reserved installation space on the bottom plate and thereby maximizing the receiving space for electrical accessories.
Solution Approach 2:
Instead of having the open ends of the guiding rails face the bottom plate as in conventional designs, the patent inverts the orientation so that the open ends face the opening of the box body. This inversion allows accessories to be directly inserted from the opening without requiring additional clearance space, thus optimizing space utilization.
2Reliability
If conventional electrical accessories are fixed by bolts, then secure mounting is achieved, but it takes a lot of time to disassemble and replace these electrical accessories
Solution Approach 1:
The patent segments the fixing mechanism into a guiding rail component and a corresponding groove component. The groove in the electrical accessory engages with the guiding rail to provide positional guidance and support, while a separate limiting component (such as a limiting block or limiting groove) provides the securing function. This segmentation allows for tool-free assembly and disassembly while maintaining mounting security.
Solution Approach 2:
The patent replaces the traditional bolt-based mechanical fastening system with a groove-rail engagement system combined with a limiting component. This substitution eliminates the need for bolts, nuts, and other fastening hardware, enabling quick snap-in assembly and easy disassembly by simply releasing the limiting component, thereby significantly reducing assembly and disassembly time.

AI summary
A distribution box includes a box body, a cover plate, and at least one guiding rail. The box body has several side plates and a base plate. An opening is formed by surrounding an end of each side plate. The base plate is connected to another end of each side plate. The cover plate is detachably engaged with the box body and closes the opening. The guiding rail is disposed inside the box body and has an open end facing toward the opening. At least one electrical accessory slides into the guiding rail from the open end and is engaged with the guiding rail. With the open end facing toward the opening, the electrical accessory could be easily disassembled and assembled without reserving an installation space at a position adjacent to the open end for providing other electrical accessories, which provides an effect of saving installation space.
