Integrated Vehicle Power Unit Layout for Reduced Packaging Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle design occupies excessive space due to the inclusion of essential components like the motor, control module, and transmission mechanism, which are typically disposed within the vehicle.
Innovation Solution
A power system is designed with a housing containing distinct chambers for the motor, transmission mechanism, and control module, with a conductive member connecting the control module to both the motor and transmission mechanism, optimizing their spatial arrangement to reduce overall space occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the motor, control module, and transmission mechanism are disposed on the vehicle as separate components, then the vehicle can perform power output functions, but the occupied space increases
Solution Approach 1:
The patent integrates the motor, control module, and transmission mechanism into a single housing structure with distinct chambers. The housing unifies these components into one compact assembly that performs all power output functions while occupying less space than separate component arrangements.
Solution Approach 2:
The control module is positioned within the housing structure, with the conductive member extending through the housing to connect with the motor. This nested arrangement allows the control module to be housed within the same structural envelope as the motor and transmission mechanism, optimizing space utilization.
2Reliability
If the control module is electrically connected to the motor through a conductive member extending through the housing, then electrical connection is achieved, but the housing structure becomes more complex
Solution Approach 1:
The housing serves multiple functions: it provides structural support for the motor and transmission mechanism, encloses the control module, and acts as a conduit for the conductive member. This multi-functionality reduces the need for separate connection structures, simplifying the overall design despite the integrated arrangement.
3Volume of moving object
If the driving chamber and transmission chamber are disposed on the same side of the control chamber, then space utilization is improved, but the housing becomes more compact which may affect component accessibility
Solution Approach 1:
The patent arranges the driving chamber and transmission chamber on the same side of the control chamber in a two-dimensional layout optimization. This spatial arrangement maximizes the use of available space within the housing while maintaining appropriate access paths for maintenance and assembly operations.
