Dual-Battery Working Machine for Continuous Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working machines face efficiency deterioration due to the need for charging when the battery's stored energy is depleted, necessitating time-consuming battery replacement or charging, which interrupts travel and work operations.
Innovation Solution
The implementation of a dual battery system comprising a main battery integrated into the working machine and a detachable sub-battery that can be easily replaced, allowing continuous operation by switching to a charged sub-battery when the main battery is low, and incorporating a regenerative system to optimize energy distribution and balance weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single battery is used in the working machine, then the device complexity is reduced, but the productivity deteriorates due to charging interruptions
Solution Approach 1:
The battery system is segmented into a main battery integrated in the working machine and a sub-battery that can be detached and replaced. This allows the energy storage function to be divided into permanent and removable components, enabling quick replacement of depleted batteries without replacing the entire system, thus maintaining productivity while managing complexity.
Solution Approach 2:
The sub-battery is prepared in advance and can be quickly attached to the working machine when the main battery is depleted. This preliminary preparation of backup energy storage eliminates charging interruptions and maintains continuous operation, directly addressing the productivity issue.
2Productivity
If a detachable sub-battery is added to enable quick replacement, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The sub-battery is designed with universal attachment capabilities that allow it to be quickly connected to the working machine's power system. The standardized interface and mounting mechanism enable the sub-battery to universally replace the main battery, providing continuous operation capability without requiring complex custom integration for each replacement scenario.
Solution Approach 2:
The battery system is designed to be self-servicing through the detachable sub-battery configuration. When the main battery is depleted, the operator can independently replace it with a charged sub-battery without requiring external charging infrastructure or complex maintenance procedures, thus maintaining productivity while keeping the system manageable.
3Use of energy by moving object
If the sub-battery is positioned close to the working device, then the energy supply efficiency is improved, but the weight distribution becomes unbalanced
Solution Approach 1:
The sub-battery is positioned at a specific location on the traveling vehicle that optimizes the balance between energy supply efficiency to the working device and overall weight distribution. This localized placement consideration ensures that the battery serves its primary function of providing power while maintaining the vehicle's operational stability and balanced composition.

AI summary
A working machine includes a storage to store an energy source to drive the working machine. The storage includes a main battery in the working machine and a sub battery at a position different from the main battery. At least one of the main battery or the sub battery is attachable to and detachable from the working machine. Therefore, it is possible to replace a storage that stores an energy source and to reduce or prevent deterioration of working efficiency.
