Solution Overview
Problem
Current power supply systems for transportation systems, such as rail passenger transportation, face issues with poor maintainability, high weight, and significant space requirements due to their rigid design and high demand for electricity, leading to inefficient maintenance and increased risk of electrical corrosion.
Innovation Solution
A power supply system designed as a mesh network with identical or compatible connection devices and conductors, allowing for high current and voltage transmission, reduced weight, and enhanced maintainability through interchangeable components and prefabricated cables, enabling efficient assembly and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If fixed wiring with rigidly designed conductors and differently designed connection units is used, then power transmission capability is ensured, but weight and space requirements increase significantly
Solution Approach 1:
The patent applies universality by designing connection devices with identical or compatible terminals that can connect to multiple types of connectors (plug connectors, push-pull connectors, bayonet connectors). This single universal connection device design replaces the need for multiple differently designed connection units, reducing weight while maintaining power transmission capability across different connector types.
2Power
If fixed wiring with rigidly designed conductors and differently designed connection units is used, then power transmission capability is ensured, but space requirements increase significantly
Solution Approach 1:
The universal connection device design allows a single terminal structure to accommodate multiple connector types, reducing the space required for storing multiple different connection unit designs and simplifying the overall wiring architecture, thereby reducing space requirements while maintaining power transmission capability.
Solution Approach 2:
The patent merges multiple connection unit designs into a single universal connection device that can interface with different connector types, consolidating what would otherwise require separate components and reducing overall space requirements in the power distribution system.
3Reliability
If at least three differently designed connection units per car are provided, then power transmission and redundancy are achieved, but maintainability deteriorates
Solution Approach 1:
The universal terminal design allows maintenance personnel to work with a single connection device type regardless of which connector type (plug, push-pull, bayonet) is used, simplifying maintenance procedures and improving ease of repair while maintaining the redundancy provided by multiple connection paths.
Solution Approach 2:
The patent segments the connection system into universal terminals and interchangeable connectors, allowing the terminal (which requires maintenance) to be standardized while the connectors (which vary by application) can be independently replaced, improving maintainability without compromising redundancy.
4Power
If high current strengths and high electrical voltage are transmitted, then power supply capacity is increased, but electrical corrosion risk increases
Solution Approach 1:
The patent addresses electrical corrosion risk by changing the material parameters of the terminal components, using corrosion-resistant materials that can withstand high current strengths and high electrical voltages without deteriorating, thereby enabling increased power supply capacity while mitigating the harmful effect of electrical corrosion.

AI summary
A power supply system is provided for groups of electrical loads, wherein a group of loads can be split into at least two segments of the group of loads, such as transportation systems comprising at least two segments of transportation systems, wherein the segments each have a first end region and a second end region and also at least one electrical load which is fed with electrical power by the power supply system. To this end, the segments of the group of loads have at least one connection device at the first end region and at least one connection device at the second end region, wherein each connection device has connections which are of substantially structurally identical design and render possible electrical connection of the connection devices within one segment of the group of loads and also connection of the segments of the group of loads to one another.
