Solution Overview
Problem
Existing battery charging devices for ECMO systems are prone to battery dislodgement during transportation due to their open design, posing a risk of battery loss and potential failure from liquid ingress, especially in adverse weather conditions.
Innovation Solution
A battery charging device with a charging box featuring compartments with drainage channels, support guide ribs, elastic shielding members, and a grip that aligns with the tilt direction of the compartments, along with a liquid outlet system to prevent battery dislodgement and liquid ingress, ensuring reliable operation during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery charging device uses an open design for quick plug-and-unplug operation, then the ease of operation is improved, but the reliability of battery retention during transportation deteriorates
Solution Approach 1:
The battery compartment is segmented into multiple compartments (first battery compartment, second battery compartment) with distinct functions. The first compartment provides quick-access plug-and-unplug capability, while the second compartment offers secure retention with elastic shielding members, resolving the contradiction between operational convenience and transportation reliability.
Solution Approach 2:
Different regions of the battery charging device are designed with different qualities: the first battery compartment has an open design for ease of operation, while the second battery compartment incorporates elastic shielding members and drainage channels for enhanced reliability and liquid protection during transportation.
Solution Approach 3:
The battery compartments are designed with asymmetric characteristics - the first compartment prioritizes accessibility with its open design, while the second compartment prioritizes security with elastic shielding members that actively constrain the battery, creating a balance between operational ease and transportation reliability.
2Object-affected harmful factors
If the battery compartment is designed with drainage channels and elastic shielding members, then the protection against liquid ingress is improved, but the device complexity increases
Solution Approach 1:
Drainage channels are pre-configured in the battery compartments to guide liquid away from critical components before liquid ingress can cause damage. Elastic shielding members are pre-positioned to automatically contact and protect the battery inlet end, providing proactive protection against liquid harm without requiring complex active control systems.
Solution Approach 2:
The elastic shielding member acts as an intermediary between the battery and the harmful liquid environment. It provides a simple yet effective barrier that protects the battery inlet end from liquid ingress while maintaining the overall simplicity of the device structure.
3Duration of action of moving object
If multiple batteries are prepared for long-term transportation, then the duration of action is improved, but the loss of time for battery replacement increases
Solution Approach 1:
The battery charging device incorporates a switching power supply that dynamically switches between multiple batteries during transportation. This allows the system to maintain continuous operation for extended durations by automatically transitioning between battery sources, eliminating the need for manual battery replacement and reducing time loss.
Solution Approach 2:
The battery charging device is designed with multi-functionality to support both single-battery quick replacement mode and multi-battery long-term transportation mode. The switching power supply and multiple battery compartments enable the device to adapt to different operational requirements, providing extended duration of action without sacrificing operational efficiency.
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
The device significantly reduces the risk of battery dislodgement and failure by maintaining secure battery placement and effective liquid drainage, enhancing reliability and safety during transportation.
Implementation Method 1
an end of the battery compartments away from the inlet end is lower than the inlet end of the battery compartments... a liquid in the battery compartment is discharged through the second opening and the drainage channel

AI summary
A battery charging device suitable for portable operation includes a charging box with a grip is provided on one side of the top of the charging box near a first opening, and when the battery charging device is lifted by the grip, the tilt direction of the battery charging device is consistent with the tilt direction of a battery compartment. The battery charging device can thereby reduce the risk of the battery easily falling out of the battery compartment during transportation, which improves the reliability of the battery charging device during transportation.
