Solution Overview

Problem

Conventional distributor blocks with two connection points on the connection side either have an unfavorable large overall width or can only handle currents below a certain threshold due to small bore diameters, limiting their application in electrical installations.

Innovation Solution

A distributor block design featuring a fixing part that can be moved against the underside of a clamping body, allowing two connection points, one circular and one rectangular, to be arranged in different levels, enabling the connection of both round and flat conductors and supporting higher current intensities like 250 amperes while maintaining a compact width.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If two connection points are provided on the connection side in the same plane, then both round and flat conductors can be connected, but the overall width increases to an unfavorable extent

Engineering Contradiction:
Improveconnection capability for different conductor geometriesVSAvoidoverall width
Core Design Contradiction:
Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The patent applies dimensionality change by arranging the two connection points in different levels (vertical stacking) rather than in the same plane. The first connection point is positioned at a higher level while the second connection point is positioned at a lower level, allowing both round and flat conductors to be connected without increasing the overall width of the distributor block.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If two connection points are provided on the connection side next to each other, then both round and flat conductors can be connected, but only bores with comparatively small diameter are possible, limiting current intensity

Engineering Contradiction:
Improveconnection capability for different conductor geometriesVSAvoidcurrent transmission capability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent resolves this contradiction by positioning connection points at different vertical levels. This spatial arrangement allows each connection point to have an adequately large bore diameter for high current transmission (250 amperes or more) while still accommodating both round and flat conductors through the respective connection points.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Length of stationary object

If only one connection point is provided on the connection side, then the overall width remains small, but the distributor block cannot handle higher current intensities requiring larger conductor cross-sections

Engineering Contradiction:
Improveoverall widthVSAvoidcurrent transmission capability
Core Design Contradiction:
Length of stationary objectVSReliability

Solution Approach 1:

The patent overcomes this limitation by providing two connection points arranged in different levels. This vertical arrangement allows the distributor block to accept conductors with larger cross-sections (120 mm² or more) for high current transmission while maintaining a compact overall width suitable for mounting in distribution boxes.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
