Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle jump start units are limited in their ability to connect external electrical systems that are not compatible with the vehicle's electrical system, preventing the use of external power sources for starting vehicles, especially in military applications where adaptability is crucial.
Innovation Solution
A modular switch-on system that allows for the exchangeable connection of switch-on modules between the vehicle and external electrical systems, enabling adaptation of voltage and form differences through interfaces and converters, such as voltage converters, rectifiers, and inverter modules, to facilitate energy transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standardized plug connection is used for vehicle jump start units, then the connection process is simplified and standardized, but the ability to connect to external electrical systems with different voltages or plug types is lost
Solution Approach 1:
The vehicle jump start unit is designed with multiple interchangeable plug connections (e.g., 12V, 24V, and different connector types) that can be selected based on the external electrical system being connected. This allows a single device to serve multiple functions and connect to various external systems with different voltage requirements and connector types, resolving the contradiction between standardized operation and adaptability.
2Device complexity
If the vehicle jump start unit uses a fixed voltage configuration, then the internal design is simplified, but the ability to connect to external electrical systems with different voltages is prevented
Solution Approach 1:
The vehicle jump start unit is divided into multiple independent voltage configuration modules (e.g., 12V module, 24V module) that can be independently selected and connected. Each module contains the necessary circuitry for its specific voltage level, allowing the system to maintain simple internal design for each module while providing voltage compatibility through modular selection based on the external system requirements.
3Device complexity
If the on-board energy storage system is used alone, then the vehicle electrical system remains simple, but the ability to start the vehicle when energy storage is insufficient is lost
Solution Approach 1:
The vehicle jump start unit acts as an intermediary energy source between the on-board energy storage system and the starter motor. When the on-board battery has insufficient charge, the jump start unit provides additional energy through its own power source or external connection, enabling the starter motor to operate. This mediator approach maintains the simplicity of the original electrical system while enhancing starting reliability under various conditions.
