Train Load Management via Dynamic Priority Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information control systems face challenges in managing load capacities and priorities across multiple vehicles, particularly when power supply malfunctions occur, as they require complex hardware or software changes and do not allow for immediate arbitrary selection of device priorities or load limits.
Innovation Solution
A vehicle information control device with a user-friendly interface for displaying apparatus states, allowing users to easily set and change load limits and priorities through screen operations, enabling the management of load capacities and distribution of surplus power within capacity ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hardware or software changes are made to alter priorities or load limits, then the system can adapt to power supply malfunctions, but the complexity of the system increases and immediate user adjustment becomes impossible
Solution Approach 1:
The patent implements dynamic adjustment of priorities and load limits through a user interface, allowing real-time modification without hardware changes. The control device enables users to freely set priorities and load limits based on current operational needs, making the system adaptable while maintaining simple architecture.
Solution Approach 2:
The patent introduces an information display device as an intermediary between the user and the load management system. This mediator allows users to view current states and adjust priorities/load limits through a user interface, enabling flexible adaptation without direct hardware modification or complex software changes.
2Productivity
If arbitrary selection of devices for limiting load capacities is enabled, then the system can optimize power distribution, but the ease of operation decreases due to complex configuration requirements
Solution Approach 1:
The patent enables self-service operation where users can independently adjust priorities and load limits through a simple user interface on the information display device. The system automatically processes these user inputs to optimize power distribution, eliminating the need for complex manual configuration while maintaining operational simplicity.
Solution Approach 2:
The patent implements feedback mechanisms where the information display device shows current apparatus states, priorities, and load limits to users. This feedback loop allows users to make informed adjustments and understand the impact of their settings, simplifying the operation while achieving optimal power distribution.
3Loss of information
If the system displays detailed states of all apparatuses, then users can make informed decisions about load management, but the information display complexity increases
Solution Approach 1:
The patent segments the information display into organized sections showing apparatus states, priorities, and load limits. The information display device presents data in a structured format that is comprehensive for decision-making yet organized to avoid overwhelming complexity, allowing users to easily navigate and understand the system state.

AI summary
In general, a system of activating loads of a plurality of apparatuses based on priorities so as to set the current supplied to the loads of the apparatuses within a rated range is performed in a load management function in a train with a plurality of connected vehicles. Arbitrary selection of devices for limiting the load capacities from various devices with different load capacities is difficult in the system, when the load capacities of all apparatuses cannot be secured due to malfunction in part of the power supply devices mounted on the plurality of vehicles. Furthermore, the priorities or load limits need to be changed by hardware or software when part of the apparatuses with high priorities need to be limited to operate apparatuses with low priorities in the operation of the vehicles. The user cannot immediately set the priorities or load limits. Provided is a vehicle information control device with a load management function of limiting loads of apparatuses according to vehicle apparatus states within capacity ranges with a reduction in capacities of vehicle power supplies mounted on a plurality of vehicles and calculating and distributing surplus power.
