Electric Vehicle Component Mounting for Weight Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concentrating heavy electrical components in one portion of an electric vehicle makes it difficult to balance the vehicle's weight effectively.
Innovation Solution
A component mounting arrangement where the battery is mounted in a longitudinally middle portion, the charger is positioned rearward, and high-power electrical components are dispersed on both sides of the battery along the longitudinal direction of the vehicle body, allowing for better weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If heavy electrical components are concentrated in one portion of the vehicle, then the device complexity is reduced and ease of manufacture is improved, but the weight balance of the vehicle deteriorates
Solution Approach 1:
The electrical components are segmented into two groups and placed in different longitudinal zones: the charger is positioned in the rearward portion while high-power electrical components are positioned in the forward portion, with the battery in the middle. This segmentation resolves the weight balance issue while maintaining manufacturing simplicity through standardized mounting positions.
Solution Approach 2:
The arrangement transitions from concentrating components in a single location to distributing them along the longitudinal dimension of the vehicle. By utilizing the longitudinal space effectively with the battery centrally located and other components at opposite ends, the patent achieves weight balance without compromising ease of manufacture.
2Device complexity
If heavy electrical components are concentrated in one portion of the vehicle, then the device complexity is reduced, but the weight distribution deteriorates
Solution Approach 1:
The electrical system is segmented into functionally distinct components placed in different longitudinal zones. The charger occupies the rearward portion, high-power components occupy the forward portion, and the battery is centrally positioned, creating a balanced weight distribution while maintaining relatively simple device architecture.
Solution Approach 2:
Different portions of the vehicle are assigned different electrical components based on their functional requirements and weight characteristics. This local quality approach ensures that each zone contains appropriate components, achieving overall weight balance without significantly increasing device complexity.
3Stability of the object's composition
If electrical components are dispersed on opposite sides of the battery, then the weight balance is improved, but the device complexity increases
Solution Approach 1:
The electrical components are segmented into two main groups positioned on opposite sides of the battery along the longitudinal axis. This segmentation achieves weight balance while the modular nature of the segmentation keeps device complexity manageable through standardized interfaces and mounting arrangements.
