Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power converters face challenges in assembly and configuration due to their size and weight, particularly when interacting with systems like photovoltaic systems, where a modular and lightweight design is desirable for efficient integration and repair.
Innovation Solution
A modular power converter design featuring a first and second housing with a coupling element that uses detent connections and slots for secure latching, allowing for easy assembly and configuration, and includes features like through-recesses for electrical connections and a wall bracket for stable mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power converters are designed with integrated housings for high power handling, then electromagnetic compatibility and protection class are improved, but weight and volume increase making assembly and repair difficult
Solution Approach 1:
The housing is divided into a first housing and a second housing that can be separately assembled. Each housing can be optimized independently - the first housing for electromagnetic shielding and protection class requirements, and the second housing for weight reduction and ease of assembly. The coupling element with detent connection enables secure assembly while maintaining modular flexibility.
2Reliability
If power converters are designed as integrated units, then electromagnetic compatibility is improved, but assembly complexity and difficulty of repair increase
Solution Approach 1:
The power converter is segmented into modular components housed in separate first and second housings. These modules can be independently assembled, inspected, and repaired. The detent connection via coupling element allows for tool-free or minimal-tool assembly and disassembly, significantly improving ease of repair while maintaining electromagnetic compatibility through proper shielding in each module.
3Ease of operation
If modular housing design is implemented, then ease of assembly and configuration is improved, but structural stability may be reduced
Solution Approach 1:
The coupling element is pre-designed with specific detent connection features including slots and latching mechanisms. The slots are pre-positioned on the housings to align with the coupling element features. This preliminary design of connection features ensures that when modules are assembled, they achieve stable structural connection without requiring complex assembly procedures or additional stabilization measures.
