Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery exchange stations are complex and require large configurations with high initial investment, and vehicles unable to reach these stations due to battery depletion face challenges in battery exchange.
Innovation Solution
A battery exchange cart with wheels, a frame, and a movable arm unit that can hold batteries, allowing manual exchange by reducing the effort required for alignment and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a battery exchange station is used, then battery exchange can be performed automatically, but the configuration becomes complex and requires large space with high initial investment
Solution Approach 1:
The patent extracts the essential battery exchange function from the complex automated exchange station system. By removing unnecessary automation components (actuators, sensors, control systems) and retaining only the core functional elements (frame, arm unit, holding mechanism), the invention achieves manual battery exchange with minimal configuration while preserving the fundamental exchange capability.
Solution Approach 2:
The patent employs simple, inexpensive components that can be easily replaced or adjusted. The cart uses basic structural elements (frame, wheels, arm) without expensive automated systems, making it a cost-effective solution that sacrifices full automation for simplicity and affordability.
2Ease of operation
If a battery exchange station is used, then battery exchange can be performed, but the station requires large configuration and high initial investment
Solution Approach 1:
The patent divides the battery exchange function into portable, modular components. Instead of a large fixed station, the exchange capability is segmented into a compact cart with frame, wheels, and arm unit that can be manually operated in limited spaces, making the system adaptable to various locations without requiring dedicated large-scale infrastructure.
Solution Approach 2:
The patent inverts the traditional approach by making the exchange device mobile rather than fixed. Instead of bringing vehicles to a large stationary exchange station, the cart can be moved to where the vehicle is located, reversing the spatial relationship and enabling exchange in confined or remote areas.
3Ease of operation
If a battery exchange station is used, then battery exchange can be performed, but vehicles unable to travel to the station cannot exchange batteries
Solution Approach 1:
The patent reverses the service delivery model: instead of requiring vehicles to travel to a fixed exchange station, the portable cart can be transported to the vehicle's location. This inversion of mobility enables battery exchange for vehicles that cannot move, such as those depleted of power, thereby expanding service accessibility to all vehicles regardless of their mobility status.
Solution Approach 2:
The portable cart serves as an intermediary between the battery exchange service and vehicles that cannot reach fixed stations. By acting as a mobile intermediary, the cart bridges the gap between stationary infrastructure and immobile vehicles, enabling exchange in situations where traditional stations cannot serve.

AI summary
A battery exchange cart according to the present disclosure is a battery exchange cart used for exchanging a battery, and including: wheels including at least a rear wheel and a front wheel; a frame part including: a bottom frame configured to connect between the wheels, and a vertical frame provided upright in a vertical direction from the bottom frame; and an arm unit including a battery holding arm protruding forward from the vertical frame and configured to hold a battery. The arm unit is supported by the vertical frame in a movable manner in an up-down direction and in a horizontal direction perpendicular to a traveling direction of the battery exchange cart.
