Inverter Casing Set-Back for Compact Motor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric or hybrid vehicle drive systems face challenges in optimizing space utilization due to the bulk of components like inverters, which hinder efficient integration with other components such as electric motors and batteries, leading to suboptimal space savings within the vehicle.
Innovation Solution
The inverter design features a casing with a set-back in the filtering component housing that extends transversely from the power component housing, creating space for additional components like the electric motor, and includes connectors for energy and charging, along with a passage for communication and a drive shaft opening, enhancing integration and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are mounted one on the other in a simple integrated assembly, then integration is achieved, but space saving in the vehicle is insufficient
Solution Approach 1:
The second casing part extends from the first casing part along a transversal direction (perpendicular to the first part), creating a multi-dimensional layout rather than simple stacking. This dimensional change optimizes space utilization within the vehicle while maintaining component integration.
Solution Approach 2:
The inverter assembly is designed to be housed within or integrated with the electric motor assembly, creating a nested configuration where the inverter casing occupies the space between the power component housing and filtering component housing, effectively utilizing available space.
2Volume of moving object
If the inverter casing is made compact to save space, then volume is reduced, but integration with other components becomes difficult
Solution Approach 1:
The casing is divided into two distinct parts: a first casing part housing power components and a second casing part housing filtering components. This segmentation allows each part to be optimized independently for its function while maintaining overall compactness and integration capability.
Solution Approach 2:
The second casing part extends transversally from the first casing part, creating a compact yet integrable structure that can accommodate other vehicle components in the available space without compromising integration capability.
3Reliability
If power components and filtering components are housed separately, then component functionality is maintained, but overall assembly bulk increases
Solution Approach 1:
The power component housing and filtering component housing are merged into a single integrated inverter assembly with a unified casing structure, reducing overall assembly bulk while maintaining separate functional zones for power and filtering components.
Solution Approach 2:
The filtering component housing is positioned within the overall inverter assembly structure, nesting the filtering function within the power conversion assembly, thereby reducing total assembly bulk while preserving both functionalities.
