Stacked-Module Power Cabinet Positioning for Reliable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing small household power cabinets face issues with complex fixing structures and cumbersome assembly due to relative displacement of modules caused by external forces, leading to arcing or dumping during stacking.
Innovation Solution
A power cabinet design featuring positioning grooves and protrusions on modules, combined with an assembly member, allows for simplified assembly by limiting module positions, reducing the need for individual fixings and enhancing structural stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixing is performed for each mounting of modules, then module position stability is improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The patent combines multiple fixing functions into a single integrated fixing structure. The fixing member spans across multiple modules and connects to both the first and second modules simultaneously, consolidating what would traditionally require separate fixing operations for each module into one unified assembly step.
Solution Approach 2:
The fixing member serves multiple functions: it positions and secures both the first module and the second module, provides structural support across multiple layers, and prevents relative displacement between modules. This multi-functional design eliminates the need for separate fixing components for each module.
2Reliability
If individual fixing is applied to each module, then assembly reliability is improved, but assembly time and labor increase
Solution Approach 1:
The fixing structure is pre-configured with positioning grooves and protrusions that automatically align modules during assembly. The fixing member is designed to engage with multiple modules simultaneously, so that when installed, it immediately provides reliable positioning and securing for all modules without requiring sequential individual fixing operations.
3Stability of the object's composition
If multiple fixing components are used for each module, then position limitation is improved, but parts and material consumption increase
Solution Approach 1:
The patent merges multiple fixing components into a single fixing member that performs the positioning and securing functions for multiple modules simultaneously. This reduces the total number of parts required while maintaining effective position limitation through the integrated design that spans across module interfaces.

AI summary
Provided is a power cabinet, which belongs to the technical field of power cabinets. The power cabinet includes a first module provided with a first assembly portion and a second module provided with a second assembly portion. At least one first module and at least one second module are stacked in a vertical direction. Two ends of an assembly member are respectively connected to two of the first assembly portion, the second assembly portion, or a support structure in a site where the power cabinet is located. The first module has a first positioning groove formed on a bottom surface of the first module. The second module has a second positioning protrusion provided on a top surface of the second module and a second positioning groove formed on a bottom surface of the second module; or the first module has a first positioning groove formed on the bottom surface of the first module, and the second module has a second positioning groove formed on the top surface of the second module and a second positioning protrusion provided on the bottom surface of the second module; or the first module is provided with a first positioning protrusion on a top surface of the first module, and the second module has a second positioning protrusion provided on the top surface of the second module and a second positioning groove formed on the bottom surface of the second module. Through the arrangement of the positioning structures and the assembly member as described above, assembly steps are simplified, mounting man-hours are shortened, and use of parts is reduced.
