Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle driving modules have low space utilization and complex assembly processes due to separate installation of the vehicle interior air conditioning compressor and driving motor, leading to inefficient use of interior space and increased manufacturing complexity.
Innovation Solution
A compact driving module integrating a vehicle driving motor, gear device, vehicle interior air conditioning compressor, and an integrated control module with power conversion devices, which includes a central processing unit for unified control and shared power conversion circuit units, along with a heat exchanger for efficient heat management, all housed within a modular structure that minimizes part count and optimizes space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle interior air conditioning compressor and vehicle driving motor are separately installed, then vibration prevention and serviceability are improved, but space utilization is reduced and assembly complexity increases
Solution Approach 1:
The patent combines the air conditioning compressor and driving motor into a single integrated module mounted on the case. The compressor is positioned adjacent to the motor with shared mounting structures, reducing the total space occupied while maintaining operational independence. The integration allows both components to benefit from common structural support and proximity without compromising vibration isolation through appropriate mounting design.
2Ease of repair
If the vehicle interior air conditioning compressor and vehicle driving motor are separately installed, then serviceability is improved, but assembly complexity increases
Solution Approach 1:
The integrated module is designed with segmented construction where the compressor and motor are mounted on a common case but can be independently accessed. The module includes separate mounting brackets and connection points that allow individual component removal or replacement without disassembling the entire assembly, maintaining serviceability while reducing overall part count.
3Device complexity
If power conversion devices are integrated into a single control module, then device complexity is reduced and space utilization is improved, but manufacturing precision requirements increase
Solution Approach 1:
The control module integrates multiple power conversion devices (first power conversion device for the motor, second power conversion device for the compressor) into a single housing. The module uses standardized mounting interfaces and common electrical connection protocols that allow different power conversion devices to be accommodated within the same structure, reducing manufacturing precision requirements through design standardization.
