Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing busbar distributors face challenges in accommodating different voltage supplies and wiring configurations across various power systems, leading to increased manufacturing complexity and costs due to the need for current transformers to adjust voltage levels.
Innovation Solution
A busbar distributor design that allows for voltage and power system adjustments by exchanging line elements with standardized, releasable plug connections, enabling connection of conductors between the building energy supply and consumer terminals without requiring voltage adjustment through transformers, using a connector that can connect phase conductors to neutral conductors or multiple phase conductors for voltage stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current transformers are used to adjust voltage levels for different power systems, then voltage compatibility is achieved, but manufacturing complexity and costs increase
Solution Approach 1:
The busbar distributor is divided into modular components: a standardized consumer terminal unit and exchangeable line elements. Each line element contains pre-configured conductors for specific voltage systems (110V or 230V), allowing the system to adapt to different power grids by simply swapping the line element rather than using complex transformers.
Solution Approach 2:
The connector is designed with universal compatibility to accept different line element configurations. The same consumer terminal and connector can work with multiple voltage systems (110V single-phase, 230V single-phase, 230V three-phase) by exchanging the line element, making the system multi-functional without requiring voltage transformation equipment.
2Adaptability or versatility
If current transformers are used to adjust voltage levels for different power systems, then voltage compatibility is achieved, but costs increase
Solution Approach 1:
By segmenting the power connection system into standardized consumer terminals and exchangeable line elements, the patent eliminates the need for expensive transformers. Each line element is a simple cable assembly with pre-configured conductors, significantly reducing material and manufacturing costs compared to voltage transformation equipment.
Solution Approach 2:
The line elements are designed as inexpensive, easily replaceable cable assemblies rather than permanent installed infrastructure. When a customer needs to adapt to a different voltage system, they simply replace the line element rather than investing in costly transformers, making the adaptation process economically viable.
3Ease of operation
If standardized connector design is used for easy adaptation, then ease of operation is improved, but handling different voltage configurations may lead to connection errors
Solution Approach 1:
The connector and line element interfaces are designed with asymmetric, non-interchangeable geometries for different voltage configurations. For example, a 110V line element has a different plug configuration than a 230V line element, physically preventing incorrect insertion. This asymmetric design ensures that only the correct voltage configuration can be connected to the consumer terminal.
Solution Approach 2:
The correct conductor configurations for different voltage systems are pre-established in the line elements during manufacturing. The wiring inside each line element is pre-configured according to the specific voltage system it serves, eliminating the need for on-site wiring decisions and reducing the risk of incorrect connections during installation.

AI summary
The invention involves a busbar distributor for electrical energy, and uses at least one consumer terminal (CT) for at least one consumer for supplying the consumer with electrical energy, as well as at least one connecting element for connecting a building energy supply (BES) to at least one high-voltage busbar, which connecting element connects the consumer to the BES. The distributor further has at least one line element which is provided between the connecting element and the CT, and a connector which is arranged between the CT and the connecting element. The connecting element has at least two conductors for supplying power to the CT. Also, the connector is connected, on an energy supply side, to the line element, which is formed having two conductors for energy supply which can be connected to the BES. The line element is exchangeable depending on the actual voltage and/or the power system of the building energy supply.
