Stacked Power Supply Module Assembly for Three-Direction Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power supply modules require complex fixing structures and cumbersome installation processes due to relative displacement during stacking, leading to issues like arcing or toppling.
Innovation Solution
The solution involves using at least two power supply modules, first structural members for one-directional fixation, and second structural members for additional directional fixation, allowing for secure stacking and reduced displacement, thereby simplifying the installation process and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixing methods are used to prevent relative displacement between power supply modules, then safety is improved, but the fixing structure becomes complex and the installation process becomes cumbersome
Solution Approach 1:
The patent combines the first structural members (protrusions) and second structural members (grooves) into an integrated fixing system where both components work together as a unified solution. The protrusions and grooves are designed to mate with each other, creating a single coordinated fixing mechanism rather than separate complex fixing structures, thereby reducing overall device complexity while maintaining safety.
Solution Approach 2:
The fixing structure is segmented into two distinct functional components: first structural members (protrusions) that extend from one power supply module and second structural members (grooves) that receive the protrusions. This segmentation allows each component to have a specific, simplified function, making the overall system easier to manufacture and install while maintaining reliability.
2Reliability
If conventional fixing methods are used to prevent relative displacement between power supply modules, then safety is improved, but the installation process becomes cumbersome
Solution Approach 1:
The first structural members (protrusions) and second structural members (grooves) are pre-configured on the power supply modules during manufacturing. This preliminary action means that during installation, the modules simply need to be aligned and inserted, with the fixing structure already in place, eliminating the need for complex assembly steps during installation and making the process straightforward and quick.
3Device complexity
If power supply modules are stacked without fixation structures, then the structure is simple and installation is quick, but relative displacement occurs leading to arcing or toppling
Solution Approach 1:
The fixing structures (protrusions and grooves) are applied locally at specific locations on the power supply modules rather than requiring a complete structural redesign of the entire module. This local quality approach allows the majority of the module structure to remain simple while adding fixation capability only where needed, maintaining overall structural simplicity while ensuring stability.

AI summary
A stacked power supply modules is provided. At least two power supply modules are stacked, and two adjacent power supply modules are limited and/or fixed in at least one direction through a corresponding first structural member. Furthermore, the power supply modules are limited and fixed in three directions by the first structural member together with a second structural member, thereby enabling the locking of the stacked power supply modules in the three directions after the installation and avoiding displacement after the installation.
