Solution Overview

Problem

Existing busbar systems are complex and difficult to produce and electrically contact due to the lateral integration of electrical lines in contact webs, which increases production costs and complicates electrical connections.

Innovation Solution

A busbar system with a profile featuring grooves of different depths, allowing electrical lines to be inserted in the depth direction, simplifying production and electrical contacting, and incorporating a plug holder with reverse polarity protection for secure and easy connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If electrical conductors are laterally positioned within contact bridges, then the busbar can accommodate different conductor heights, but the manufacturing becomes complex and electrical contacting becomes difficult

Engineering Contradiction:
Improveaccommodation of different conductor heightsVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent transitions from lateral positioning of electrical conductors in the horizontal plane to depth-based positioning in the vertical dimension. Grooves of different depths accommodate conductors at different levels, transforming a complex lateral arrangement into a simpler vertical stacking configuration that is easier to manufacture and assemble.

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

2Adaptability or versatility

If electrical conductors are laterally positioned within contact bridges, then different conductor heights are accommodated, but electrical contacting becomes relatively difficult

Engineering Contradiction:
Improveaccommodation of different conductor heightsVSAvoidelectrical contacting ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent enables electrical contacting from a single side by using grooves of varying depths. Connectors can access conductors at different heights by inserting to appropriate depths, eliminating the need for lateral access to multiple sides and simplifying the electrical connection process.

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

3Ease of manufacture

If grooves of different depths are used to position electrical conductors, then manufacturing is simplified and electrical contacting is easier, but the busbar profile requires more complex groove geometry

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidgroove geometry complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The busbar profile features grooves with locally varied depths - shallower grooves for higher conductors and deeper grooves for lower conductors. This localized variation in groove geometry allows different conductor positions to be accommodated within a single standardized profile design, balancing manufacturing simplicity with functional requirements.

Inventive Principle:
Principle #3Local quality
