Modular Power Cabinet Assembly for Stable Stack Positioning
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 traditional fixing methods are used for each module mounting, then module position stability is improved, but assembly complexity and time increase
Solution Approach 1:
The patent combines multiple fixing functions into a single integrated assembly member that simultaneously connects multiple modules. This assembly member integrates positioning grooves, fixing protrusions, and connection features into one component, eliminating the need for separate fixing operations for each module and simplifying the overall fixing structure.
Solution Approach 2:
The positioning grooves and fixing protrusions are pre-formed on the modules and assembly member during manufacturing. This preliminary preparation of positioning features allows for rapid assembly without requiring complex fixing operations during installation, as the modules are designed to fit together with predetermined positioning characteristics.
2Stability of the object's composition
If traditional fixing methods are used for each module mounting, then module position stability is improved, but assembly time increases
Solution Approach 1:
The assembly member integrates multiple fixing functions into a single operation, allowing simultaneous connection of multiple modules. This merging of fixing operations into one assembly action significantly reduces the time required compared to performing separate fixing operations for each module.
Solution Approach 2:
The positioning grooves and fixing protrusions are pre-formed on the modules and assembly member during manufacturing. This preliminary preparation enables rapid assembly by eliminating the need for complex fixing operations during installation, as the modules are designed to fit together with predetermined positioning characteristics.
3Reliability
If multiple fixing operations are performed for each module, then connection reliability is improved, but number of parts increases
Solution Approach 1:
The assembly member consolidates multiple fixing functions into a single integrated component. This assembly member includes positioning grooves, fixing protrusions, and connection features all in one part, replacing what would traditionally require multiple separate fixing components and operations.
Solution Approach 2:
The assembly member is designed as a universal component that performs multiple functions simultaneously: positioning multiple modules, providing fixing connections, and ensuring structural stability. This multi-functional design eliminates the need for specialized fixing parts for each module while maintaining connection reliability.
