Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inverters face issues with electromagnetic radiation due to wired connections between modules, leading to poor performance and instability, as well as complexity in organizing and maintaining these connections.
Innovation Solution
The inverter design eliminates wired connections by using plug-in modules, where the transmission module is plugged into the conversion module, and the communication module is plugged into either the transmission or inductor module, facilitating stable and efficient electrical connections while protecting against electromagnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If modules are electrically connected through wires, then electrical connection is established, but electromagnetic radiation occurs and stability deteriorates
Solution Approach 1:
The patent extracts and removes the wires from the system by implementing direct plug-in connections between modules. The conversion module, transmission module, inductor module, and communication module are connected through direct physical plugging without intermediate wiring, thereby eliminating the source of electromagnetic radiation while maintaining electrical connectivity.
Solution Approach 2:
The patent introduces a standardized plug interface as an intermediary mechanism between modules. This plug-in interface serves as a mediator that enables direct electrical connection without requiring traditional wires, thus resolving the contradiction between establishing electrical connection and avoiding electromagnetic radiation.
2Ease of operation
If modules are connected through intertwined wires, then electrical connection is established, but organization and maintenance become difficult
Solution Approach 1:
The patent segments the electrical connection system into independent modular units, each with standardized plug interfaces. The conversion module, transmission module, inductor module, and communication module are divided as separate entities that connect through plugs rather than intertwined wires, making organization and maintenance straightforward.
Solution Approach 2:
The patent implements universal plug-in interfaces that can be used across all module connections. The standardized plug design allows any module to connect to any other module through the same interface mechanism, simplifying organization and maintenance while reducing device complexity.

AI summary
Provided is an inverter, comprising a conversion module, a delivering module, an inductance module, and a communication module. The delivering module and the inductance module are separately connected to the conversion module by means of plug-in, and the communication module is electrically connected to the delivering module, the conversion module, or the inductance module by means of plug-in. The electrical connection between the modules inside the inverter can be realized by means of plug-in, such that the electrical connection between the modules is more convenient, the working efficiency and maintenance efficiency of electrical connection are improved, and the influence of the electromagnetic interference, which is occurred when the modules are connected by means of wires, on the working stability of the modules can be avoided, thereby ensuring the working stability of the inverter.
