Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrically operated and hybrid work vehicles face challenges in efficiently managing battery capacity for varying work durations, requiring large-capacity batteries for long tasks but resulting in increased weight and reduced stability, and lacking flexibility for short tasks.
Innovation Solution
The design incorporates a dual battery support system, allowing for the mounting of either one or two batteries depending on the task duration, with the batteries positioned to optimize weight distribution and stability, and utilizing the second battery's space for storage when not 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 duration is extended, but the vehicle weight increases and stability deteriorates
Solution Approach 1:
The battery system is segmented into a first battery mounted in the first battery support section and a second battery mounted in the second battery support section. This segmentation allows the total battery capacity to be divided into manageable units, enabling the vehicle to achieve long work duration when both batteries are mounted, while avoiding excessive weight when only one battery is needed.
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 duration is extended, but the travel stability deteriorates
Solution Approach 1:
The battery system is segmented into a first battery mounted in the first battery support section and a second battery mounted in the second battery support section. This segmentation allows the total battery capacity to be divided into manageable units, enabling the vehicle to achieve long work duration when both batteries are mounted, while avoiding excessive weight when only one battery is needed.
Solution Approach 2:
The patent utilizes the vertical dimension by mounting the first battery in the first battery support section and the second battery in the second battery support section positioned differently in space. This spatial arrangement allows flexible configuration where batteries can be mounted or removed without interfering with each other, maintaining stability while providing capacity flexibility.
3Duration of action of moving object
If a large-capacity battery is mounted for long tasks, then the work duration is extended, but the vehicle handling deteriorates
Solution Approach 1:
The battery system is segmented into a first battery mounted in the first battery support section and a second battery mounted in the second battery support section. This segmentation allows the total battery capacity to be divided into manageable units, enabling the vehicle to achieve long work duration when both batteries are mounted, while avoiding excessive weight when only one battery is needed.
Solution Approach 2:
The battery configuration is made dynamic and adaptable through the removable second battery support section. The vehicle can transition between different battery configurations (one battery or two batteries) depending on task requirements, allowing optimal handling characteristics for each operational scenario.
