Electric Compressor Housing With Integrated Lifting Tab
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The modification of the center of gravity in electric powertrains due to increased compressor volume and reduced width in electric and hybrid vehicles complicates optimal lifting, as traditional lifting rings are no longer optimal in location.
Innovation Solution
A one-piece casing for the electric compressor with integrated lifting means, such as a triangular tab forming a lifting ring, allows for efficient handling and balancing based on the powertrain's center of gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electric compressor volume is increased to meet thermal management needs, then the thermal management capability is improved, but the center of gravity of the electric powertrain shifts and the lifting location becomes non-optimal
Solution Approach 1:
The lifting means is integrated directly into the compressor housing body as a one-piece structure. The lifting means extends from the body and projects outward, forming an integrated assembly that combines the compressor housing and lifting function into a single component, eliminating the need for separate lifting rings or attachment points.
Solution Approach 2:
The lifting means is positioned on the lateral side of the compressor housing rather than at the top or bottom, representing a spatial repositioning that addresses the shifted center of gravity. This lateral extension allows for optimized lifting that accounts for the new weight distribution caused by the increased compressor volume.
2Ease of operation
If traditional separate lifting rings are used, then the lifting function is provided, but additional assembly steps and increased device complexity are required
Solution Approach 1:
The lifting means is integrated directly into the compressor housing body as a one-piece structure. The lifting means extends from the body and projects outward, forming an integrated assembly that combines the compressor housing and lifting function into a single component, eliminating the need for separate lifting rings or attachment points.
Solution Approach 2:
The compressor housing body serves dual functions: it encloses and protects the electric compressor while simultaneously incorporating the lifting means as an integral part. This multi-functionality eliminates the need for separate dedicated lifting components, reducing overall device complexity.
3Area of stationary object
If the electric powertrain width is reduced for compactness, then the space efficiency is improved, but the center of gravity modification makes traditional lifting locations non-optimal
Solution Approach 1:
The lifting means is positioned on the lateral side of the compressor housing rather than at the top or bottom, representing a spatial repositioning that addresses the shifted center of gravity. This lateral extension allows for optimized lifting that accounts for the new weight distribution caused by the increased compressor volume.
Solution Approach 2:
The lifting means is specifically positioned at a location that corresponds to the modified center of gravity of the compact powertrain. By placing the lifting means where it is most effective for the new weight distribution, the design optimizes lifting performance for the specific compact configuration rather than using a generic location.
