Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional electrical busway splice connectors are used, then assembly and disassembly require significant time and effort, but the patent enables quick disconnection and reconnection without power interruption

Engineering Contradiction:
Improveease of disconnection and reconnectionVSAvoidtime for disconnection and reconnection
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The splice connector is divided into separate modular components including insulating housing sections, busbar connectors, and isolation plates that can be independently assembled and disassembled. This segmentation allows for quick reconfiguration without requiring complete disassembly of the entire connector assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector design incorporates movable and adjustable elements that allow for dynamic reconfiguration during assembly and disassembly operations, enabling operators to quickly adapt the connector to different busway configurations without fixed rigid structures.

Inventive Principle:
Principle #15Dynamics

2Reliability

If conventional splice connectors are used, then electrical isolation between adjacent busbar connectors is insufficient, but the patent provides effective isolation between horizontally and vertically adjacent connectors

Engineering Contradiction:
Improveelectrical isolation between busbar connectorsVSAvoidcomplexity of isolation structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The insulating housing sections incorporate vertically extending separating walls at specific locations where electrical isolation is needed between adjacent busbar connectors. This localized approach provides effective isolation only where required rather than using comprehensive insulation throughout the entire housing, reducing unnecessary complexity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Horizontal isolation plates are introduced as intermediary elements positioned between vertically adjacent busbar connectors to provide electrical isolation. These plates act as mediators that prevent electrical interference between adjacent connectors while maintaining a clean and organized structural design.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If simple busbar connectors are used, then connection impedance is high, but the patent achieves low impedance connections suitable for high current busbars

Engineering Contradiction:
Improveconnection impedance for high currentVSAvoidcomplexity of busbar connector
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple contact louver elements are combined within a single busbar connector assembly to create a multi-point electrical connection. This merging of multiple contact paths in parallel reduces overall connection impedance, enabling the connector to handle high current applications effectively while maintaining a compact design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The contact louver structure extends in multiple dimensions within the busbar connector, creating a three-dimensional contact network rather than simple planar contacts. This dimensional expansion increases the effective contact area and provides multiple current pathways, reducing impedance for high current busbars.

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

AI summary

A splice connector for a busway system utilizes individual connectors made of a conductive material and having a u-shaped cross-section that fit over ends of a pair of busbars to be connected to each other, and within which are mounted multi-contact louvers that extend the length of the connectors to establish a low impedance electrical connection between the connector and the respective busbars. Louvers are secured in place by a dovetail groove that retains the louvers within the connectors and causes the individual contact sections of the louvers to bow outwardly so as to press against the busbars when the connector is fitted over the busbars. The connectors are snapped into insulative housing halves or sections that align the connectors with the busbars, and that provide isolation between horizontally aligned pairs of connectors. Spacers enable different sized u-shaped connectors to fit within a standard insulative housing.
