Side Battery Housing Layout for Work Vehicles With More Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric work vehicles and tractors have limited battery storage capacity due to space constraints in their main housing, and they lack separate battery housings to increase power storage capacity without compromising motive operation, such as wheel turning.
Innovation Solution
The design includes a vehicle with a main body, front and rear wheels, and multiple battery housings (first, second, and side housings) that overlap and are spaced away from each other, allowing for increased battery storage capacity without affecting wheel turning capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single housing includes multiple batteries in series-connected sets, then electrical power storage capacity is increased, but space utilization efficiency is reduced due to gaps from vertical offset rows
Solution Approach 1:
The patent divides the battery storage system into multiple separate housings (first housing, second housing, and side housing) instead of using a single housing. Each housing contains battery modules arranged in efficient configurations. This segmentation allows each housing to be optimally packed without wasted space from vertical offsets, while collectively providing the required electrical power storage capacity through series connections between housings.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by positioning housings at different locations (forward of rear wheels, side positions) and using overlapping projections. The side housing extends in the width direction while main housings are arranged in the length direction, creating efficient use of available volume without vertical offsets that would create gaps.
2Quantity of substance
If battery storage space is located between front wheels to increase capacity, then electrical power storage is improved, but wheel turning capability is compromised
Solution Approach 1:
The patent extracts the battery housing from the space between the front wheels and relocates it to positions forward of the rear wheels and at side positions. This extraction eliminates the interference with front wheel turning while maintaining battery storage capacity. The side housing specifically is positioned to avoid the wheel turning path while maximizing space utilization.
Solution Approach 2:
The patent introduces a side housing as an intermediary battery storage solution that bridges the need for increased capacity and preservation of wheel turning capability. The side housing is positioned laterally to provide additional storage without interfering with the mechanical operation of the front wheels, effectively mediating between these two requirements.
3Quantity of substance
If separate battery housings are used to increase power storage, then battery capacity is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple battery housings into a unified electrical power supply system where the housings are series-connected to provide increased voltage and power capacity. The housings share common structural and functional characteristics (battery module arrangements, series connections) that reduce overall system complexity despite the increased number of components. The side housing merges with the main housings to create an integrated power system.
