Modular Battery Support Layout for Work Vehicle Range Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrically operated or hybrid work vehicles face challenges in efficiently managing battery capacity for varying travel distances and work durations, as they require large-capacity batteries for long distances or long work periods but not for short distances or short periods, affecting weight, stability, and convenience.
Innovation Solution
The vehicle is designed with a dual battery support system, allowing the use of one or two batteries depending on the task, with the batteries positioned to optimize weight distribution and stability, and providing additional storage space when only one battery is needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a large-capacity battery is mounted to enable long-distance travel or long-time work, then the work vehicle can travel over long distances or perform work over long time periods, but the vehicle weight increases and travel stability and handling deteriorate
Solution Approach 1:
The battery system is divided into two separate batteries (first battery and second battery) with separate support sections. The first battery is mounted in the first battery support section under the seat, while the second battery can be optionally mounted in the second battery support section between the driver section and rear travel device. This segmentation allows flexible configuration where only one battery is used for short-distance tasks (maintaining light weight) and both batteries can be used for long-distance tasks (extending duration).
2Duration of action of moving object
If a large-capacity battery is mounted to enable long-distance travel or long-time work, then the work vehicle can travel over long distances or perform work over long time periods, but the device complexity increases
Solution Approach 1:
The second battery support section is designed to serve dual purposes: it can hold the second battery when long-distance travel is needed, or it can be used as storage space for tools and baggage when only short-distance travel is needed. This multi-functionality reduces device complexity by eliminating the need for separate storage compartments while still providing the capability for extended range when required.
3Ease of operation
If the second battery is not mounted, then the vehicle weight decreases and travel stability and handling improve, but the battery capacity is insufficient for long-distance travel or long-time work
Solution Approach 1:
The battery configuration is made dynamic and adaptable to different operational requirements. The second battery support section is designed to accommodate the second battery when needed, or remain empty to serve as storage space. This dynamic flexibility allows the vehicle to optimize between weight/stability and battery capacity based on the specific task at hand, improving ease of operation for different scenarios.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables the vehicle to adapt to both long and short tasks with improved stability, handling, and convenience by optimizing battery placement and usage, while allowing for tool and baggage storage when not needed for long distances.
Implementation Method 1
