Solution Overview
Problem
Disconnecting the battery cable in a work vehicle requires caution and can lead to potential short circuits if not done correctly, posing a safety risk.
Innovation Solution
A work vehicle design with a battery switch in the earth wire, positioned outside the hood and between the battery and front axle, reduces the risk of short circuits by allowing safe and easy interruption of the battery circuit without disconnecting the cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery cable is disconnected to interrupt the battery circuit, then the natural discharge is prevented, but the operation becomes complex and safety risks increase due to potential short circuits
Solution Approach 1:
The earth wire is segmented into multiple sections with the battery switch inserted in the section wired to the outer part of the hood. This segmentation allows the circuit to be interrupted at a safe location away from the battery terminals, eliminating the need to disconnect cables directly from the battery while still achieving circuit interruption.
Solution Approach 2:
The battery switch acts as an intermediary device inserted in the earth wire between the battery and the earth terminal. This intermediary component provides a safe and easy mechanism to interrupt the battery circuit without requiring direct cable disconnection from the battery terminals, thus preventing short circuits while maintaining operational simplicity.
2Reliability
If the battery switch is placed inside the hood near the battery, then the circuit interruption is effective, but the risk of short circuits and exposure to harmful factors increases
Solution Approach 1:
The battery switch is extracted from the immediate battery compartment and repositioned in the earth wire section that is wired to the outer part of the hood. This extraction removes the switch from the high-risk area near the battery terminals while maintaining its circuit interruption function, thereby reducing exposure to short circuit risks and environmental harmful factors.
Solution Approach 2:
The battery switch serves as an intermediary component positioned in the earth wire away from the battery terminals. This intermediary placement allows the switch to effectively interrupt the circuit while being positioned in a safer location that is less susceptible to short circuit risks and environmental harmful factors such as heat and chemical exposure.
3Ease of operation
If additional components are added to the battery circuit, then the circuit control is improved, but the device complexity increases
Solution Approach 1:
The battery switch utilizes the existing earth wire structure and integrates with the current battery circuit design. By leveraging the existing earth terminal and wire routing, the switch adds circuit control functionality without requiring extensive additional components or complex modifications to the battery system.
Solution Approach 2:
The battery switch is designed to integrate with the existing earth wire and battery terminal structure, utilizing the current circuit pathways. This self-service approach allows the switch to provide enhanced circuit control while minimizing the need for additional components, as it works within the framework of the existing battery circuit architecture.
