Solution Overview

Problem

Current electrical power distribution systems for modular devices, such as circuit breakers, are inefficient in terms of compactness and require significant space for signaling and control systems, which complicates wire-to-wire connections and overall system size.

Innovation Solution

A power distribution device with a compact design that integrates signaling and control processing systems alongside the electrical connection device, utilizing a communication bus and elastic connection terminals, allowing for a more efficient use of space by arranging phase and neutral terminals on each pitch of the distributor, and incorporating a movable part for the processing device to optimize space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If signaling and control processing systems are placed separately from the power distribution device, then wire-to-wire connections can be established, but the overall system size and space requirements increase significantly

Engineering Contradiction:
Improvewire-to-wire connection capabilityVSAvoidoverall system size
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent combines the signaling and control processing systems with the power distribution device into a single integrated unit. The processing device is housed within the same casing as the power bars and connection means, eliminating the need for separate housing and reducing overall system volume while maintaining full functionality for both power distribution and control signaling.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated device performs multiple functions simultaneously: it distributes electrical power through the power bars and neutral bar, processes control signals through the integrated processing device, and provides communication interfaces. This multi-functional design eliminates the need for separate dedicated spaces for control systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If traditional separate housing is used for power distribution and control systems, then functional separation is maintained, but the height and space requirements double

Engineering Contradiction:
Improvefunctional separationVSAvoiddevice height
Core Design Contradiction:
Ease of manufactureVSLength of stationary object

Solution Approach 1:

The patent transitions from a vertical stacking arrangement (separate housings one above the other) to a horizontal integration arrangement within a single casing. The processing device is positioned horizontally alongside the power distribution components, utilizing the same vertical space and reducing overall height by approximately half while maintaining functional separation through internal compartmentalization.

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

3Productivity

If elastic connection terminals are used on each pitch, then connection efficiency improves, but device complexity increases

Engineering Contradiction:
Improveconnection efficiencyVSAvoidterminal arrangement complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent employs elastic connection terminals of the same type (quarter-turn terminals) uniformly across all phase and neutral positions on each pitch. This homogeneous approach simplifies the connection process and maintains consistent performance while the repetitive modular pattern actually reduces overall complexity compared to mixed connection types.

Inventive Principle:
Principle #33Homogeneity

Solution Approach 2:

The connection system is divided into modular pitches, each containing a complete set of phase and neutral terminals. This segmentation allows for standardized, repeatable connection units that simplify installation and maintenance while improving connection efficiency through consistent elastic terminal design across all modules.

Inventive Principle:
Principle #1Segmentation

AI summary

The device (D) has connection units connecting supply bars to an electric apparatus e.g. circuit-breaker. The units have a phase and neutral terminal assembly provided on the device. The assembly has phase and neutral terminals (26, 25) that are provided along phase and neutral distribution lines (5, 4), respectively. Supply bars and the connection units release a space inside the device. The space houses a device (T) for signal processing and/or control of a modular apparatus. The device (T) extends parallel to the bars and placed above a set of distribution lines.
