Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for inductive transmission of electrical energy to moving consumers in systems like telpher and driverless transport systems face inefficiencies due to constant power supply requirements, leading to high energy losses and delayed restarts when vehicles are stationary, as they maintain maximum power even when only car controls are needed.
Innovation Solution
A device and method that determine the total power required by each route section based on the operating states of moving consumers, allowing for the actuation of current sources to supply only the necessary constant electrical current, reducing energy consumption and power losses by dynamically adjusting the power supply levels according to the demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If constant maximum power is supplied to route sections, then reliability of power supply is improved, but energy consumption and power losses increase
Solution Approach 1:
The patent applies dynamics by transitioning from static constant maximum power supply to dynamic power supply that automatically adjusts to actual demand. The control device continuously monitors power requirements of moving consumers and modulates the power supplied to each route section in real-time, ensuring reliability while eliminating energy waste during low-demand periods.
Solution Approach 2:
The invention changes the power supply parameter from fixed maximum value to variable values based on actual consumption needs. The control device adjusts power parameters (voltage, current) dynamically according to the number and power requirements of consumers present on each route section, resolving the contradiction between maintaining high power levels for reliability and reducing energy losses.
2Loss of time
If constant maximum power is supplied to route sections, then immediate vehicle restart is enabled, but energy consumption increases
Solution Approach 1:
The control device performs preliminary action by detecting when route sections become empty and proactively reducing power supply before vehicles need to restart. This anticipatory control allows the system to minimize energy consumption during idle periods while ensuring power is restored quickly when consumers are detected, thus reducing both energy waste and maintaining acceptable restart response times.
3Use of energy by moving object
If route sections are divided with separate current sources, then power can be adjusted per section, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a control device that performs multiple functions: it monitors consumers on multiple route sections, calculates power requirements, and controls multiple current sources through a single integrated system. This multi-functional approach enables per-section power adjustment without proportionally increasing overall system complexity, as one control device manages all route sections.

AI summary
The invention relates to a device for inductively transmitting electrical energy to displaceable consumers (F1-F13) that can be moved along a track, having a primary conductor arrangement (2) divided into route segments (3-7) that are electrically separated from each other, and extending along the track, wherein individual route segments (3-7) are each associated with at least one current source (3′-7′) for imprinting a continuous current into each of the route segments (3-7), and to a corresponding method. The aim of the invention is to supply the displaceable consumers in an energy-saving manner with electric energy matched to demand, and to allow short reaction times when operating the device. This aim is achieved by providing the device with a means (11) for determining the total power of the displaceable consumers (F1-F13) present in each of the individual route segments (3-7) and with a means (11) for actuating the current sources (3′-7′) for applying the electrical continuous current corresponding to the total power required for each route segment (3-7), or by determining, according to the method, the required total power of the displaceable consumers (F1-F13) present in each route segment and applying an electrical continuous current to each route segment (3-7) by means of the associated current source (3′-7′), said current corresponding to the total power required therein.
