Integrated Drive Assembly Housing for Compact Vehicle Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle drive assemblies occupy excessive space due to separate components like motors, reduction gearboxes, and axles, leading to inefficient use of vehicle space.
Innovation Solution
Integration of the motor housing and axle housing with the reduction gearbox housing, eliminating gaps between these components to create a more compact drive assembly structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the motor housing, axle housing, and reduction gearbox housing are kept as separate components, then each component can be manufactured and assembled independently, but the overall drive assembly occupies excessive space
Solution Approach 1:
The patent merges the motor housing, axle housing, and reduction gearbox housing into a single integrated housing structure. This consolidation eliminates the gaps and spaces that would exist between separate components, thereby reducing the overall volume occupied by the drive assembly while maintaining the functional independence of each subsystem through internal separation structures.
2Volume of moving object
If separate housings are used for motor, axle, and reduction gearbox, then manufacturing and assembly are simplified, but unnecessary space is occupied
Solution Approach 1:
The integrated housing design combines multiple housing functions into one monolithic structure, eliminating the need for separate manufacturing and assembly of individual housings. This approach maximizes space utilization while the internal modular design allows for streamlined manufacturing processes.
3Volume of moving object
If integrated housing design is used, then space is saved and vehicle miniaturization is facilitated, but manufacturing precision requirements increase
Solution Approach 1:
The integrated housing is designed with internal segmentation that creates distinct functional zones for the motor, reduction gearbox, and axle components. These internal separation structures allow for standardized manufacturing of modular components while maintaining the compact integrated form factor, thereby reducing the precision requirements for the overall housing manufacturing.
