Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power conversion devices for electric vehicles face increased costs due to the need to change specifications of expensive large-sized components and wiring members when interface positions are altered, leading to size and heat-generation issues.
Innovation Solution
A power conversion device design with a power conversion portion, first and second connection portions, first and second wiring portions, and a housing with specific peripheral wall configurations, allowing for adaptable wiring without changing specifications of expensive components, using universal connectors and shared wiring portions across different vehicle types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the interface position is changed to adapt to different vehicle types, then the adaptability of the power conversion device is improved, but the cost increases due to the need to change specifications of expensive large-sized components such as power module, transformer, and choke coil
Solution Approach 1:
The patent divides the power conversion device into a fixed power conversion portion (with standardized components) and a flexible wiring portion (with adjustable routing). This segmentation allows the expensive components to remain unchanged while adapting to different interface positions through reconfigurable wiring paths along peripheral walls.
Solution Approach 2:
The power conversion portion is designed with universal connection portions that can connect to different interface positions through various wiring routes. The standardized power module, transformer, and choke coil can serve multiple vehicle types without specification changes, achieving multi-functionality across different applications.
2Adaptability or versatility
If the interface position is changed and wiring member size increases to connect input/output portion to interface, then the adaptability is improved, but the cost of wiring member increases and heat-generation amount increases requiring additional cooling member
Solution Approach 1:
The wiring portion is designed with dynamic routing capabilities, allowing the wiring to be extended or routed along different peripheral walls depending on the interface position. This dynamic adaptation prevents excessive wiring length while maintaining flexibility for different vehicle layouts.
Solution Approach 2:
The wiring is routed along specific peripheral walls (first, second, third, or fourth peripheral wall) based on the local interface position requirements. This localized routing optimization ensures that wiring length and heat generation are minimized for each specific configuration while maintaining adaptability.
