Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing units with mounted heat exchangers face challenges in reducing their dimensions, particularly in one direction, due to the spatial requirements of the heat exchanger and other components.
Innovation Solution
The unit design incorporates an inverter case that overlaps the heat exchanger and motor case in a predetermined direction, allowing for a compact configuration by integrating these components within a shared housing structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat exchanger is mounted on a unit, then cooling function is provided, but the dimension of the unit increases
Solution Approach 1:
The heat exchanger is nested within the motor case, utilizing the internal space of the motor case to accommodate the heat exchanger components. This allows the heat exchanger to be integrated into the existing unit structure without significantly increasing the overall external dimensions of the unit.
Solution Approach 2:
The heat exchanger is arranged in an overlapping configuration with the motor case when viewed in a predetermined direction, effectively utilizing three-dimensional space rather than simply extending in one direction. This dimensional arrangement allows both components to coexist within a compact footprint.
2Volume of moving object
If the inverter case is designed to overlap the heat exchanger and motor case, then space efficiency is improved, but structural complexity increases
Solution Approach 1:
The inverter case is merged with the motor case and heat exchanger assembly, forming an integrated housing structure. The inverter case is designed to overlap with both the heat exchanger and motor case, combining multiple functional components into a unified structural arrangement that improves space efficiency.
