Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electric axle systems for vehicles require specific and costly components for the front and rear carriages, leading to increased manufacturing costs and complexity, especially when aiming for high performance and reliability.
Innovation Solution
A motor vehicle design featuring electric axles with a T-shaped front axle and U-shaped rear axle configuration, utilizing symmetrically arranged motor modules with coaxial drive shafts and gear trains, allowing for shared casings and optimized space usage, which simplifies manufacturing and reduces costs by eliminating the need for separate components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components are used for front and rear carriages, then high performance and reliability are achieved, but manufacturing cost increases significantly
Solution Approach 1:
The patent applies universality by designing a single-type motor module that can be used in both front and rear electric axles. The motor module includes a motor, reducer, and differential integrated in one unit, which can be universally installed in different axle positions. This eliminates the need to create specific components for forecarriage and rear carriage, thereby reducing manufacturing costs while maintaining performance and reliability through standardized high-quality design.
Solution Approach 2:
The patent segments the electric axle system into modular electric axles, where each axle is composed of independent motor modules. This segmentation allows the same standardized motor module to be reused in both front and rear axles, reducing overall component variety and manufacturing complexity while maintaining the mechanical independence needed for high performance and reliability.
2Reliability
If specific components are created for front and rear carriages, then high performance is achieved, but device complexity increases
Solution Approach 1:
The patent reduces device complexity by implementing a universal motor module design that serves both front and rear electric axles. Instead of creating different component sets for each axle position, the same integrated motor-reducer-differential module is used throughout, significantly reducing the variety of components needed while maintaining high performance through standardized engineering.
Solution Approach 2:
The patent merges the motor, reducer, and differential into a single integrated motor module. This consolidation reduces the number of separate components and connections needed in each axle assembly, simplifying the overall device structure while maintaining the functional performance required for high-speed electric vehicle operation.
