Side Battery Housing Layout for Work Vehicle Wheel Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric work vehicles or tractors face limitations in battery storage capacity due to limited space and lack of separate battery housings, which restricts the turning ability of front wheels.
Innovation Solution
The vehicle design includes a main housing with separate first and second battery housings located forward of the rear wheels, allowing for increased storage capacity and efficient use of space without affecting wheel turning, with battery modules aligned in rows and columns for compact storage, and series/parallel connections for optimal power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If separate battery housings are used to increase storage capacity, then battery storage capacity is improved, but device complexity increases
Solution Approach 1:
The battery system is divided into multiple separate battery housings (first battery housing and second battery housing) that can be independently installed and managed. Each housing contains battery modules arranged in specific configurations, allowing the system to achieve higher total storage capacity while maintaining modular complexity that simplifies installation and maintenance.
Solution Approach 2:
The battery housings are positioned at different vertical levels (first housing at first vertical level, second housing at second vertical level) and horizontal positions (forward and rearward of rear wheels). This three-dimensional arrangement maximizes space utilization without requiring a single large complex housing structure.
2Quantity of substance
If battery housings are positioned to maximize storage space, then battery storage capacity is improved, but wheel turning ability deteriorates
Solution Approach 1:
The battery housings are strategically positioned in specific locations (first housing forward of rear wheels at first vertical level, second housing forward of rear wheels at second vertical level) to maximize space utilization in areas that do not interfere with wheel turning radius and vehicle maneuverability.
Solution Approach 2:
By utilizing vertical stacking (first vertical level and second vertical level) and horizontal distribution (forward and rearward positions), the battery system occupies three-dimensional space efficiently without encroaching on the two-dimensional turning space required by the wheels.
3Volume of stationary object
If battery modules are arranged in compact rows and columns, then space utilization is improved, but manufacturing precision requirements increase
Solution Approach 1:
Battery modules are organized into discrete rows and columns within each housing, creating a modular grid structure. This segmentation allows for standardized manufacturing and assembly procedures, reducing the precision requirements compared to custom-fit arrangements while maximizing space utilization.
Solution Approach 2:
The row and column arrangement creates universal mounting patterns that can accommodate different battery module configurations. This standardized layout simplifies manufacturing and assembly processes while maintaining high space utilization across different vehicle models and battery capacities.
