Solution Overview

Problem

The design of secondary power distribution systems is limited by proprietary overcurrent protection devices, leading to increased costs due to restricted form factors and reduced flexibility.

Innovation Solution

The development of overcurrent protection devices with a cartridge that can removeably receive a TPA fuse, directly coupling to power input and output connections of a power distribution panel without an intermediate busbar, allowing for flexible configuration and higher density installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If proprietary overcurrent protection devices are used, then device reliability is ensured, but device complexity and cost increase due to restricted form factors and intermediate busbars

Engineering Contradiction:
Improvedevice reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the intermediate busbar component from the power distribution system. The cartridge directly couples to the power distribution panel terminals, eliminating the busbar that was previously required as an intermediate connection element. This extraction simplifies the device structure while maintaining electrical connectivity and reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the cartridge holder and electrical connection functions into a single integrated cartridge assembly. The cartridge directly couples both power input and power output terminals to the power distribution panel without requiring separate busbar components, thereby reducing device complexity while ensuring reliable power transmission.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If proprietary overcurrent protection devices with intermediate busbars are used, then electrical connectivity is ensured, but productivity decreases due to lower installation density

Engineering Contradiction:
Improveelectrical connectivityVSAvoidinstallation density
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

By removing the intermediate busbar, the cartridge occupies less space and can be installed more densely in the power distribution panel. The direct coupling mechanism eliminates the need for additional mounting space that would be required for separate busbar installations, thereby increasing installation density and productivity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the power distribution function into individual removable cartridges, each handling its own input and output connections independently. This segmentation allows for higher density installation as each cartridge is a self-contained unit that can be closely packed without requiring shared busbar infrastructure.

Inventive Principle:
Principle #1Segmentation

3Reliability

If proprietary designs are used, then device functionality is ensured, but adaptability decreases due to form factor restrictions

Engineering Contradiction:
Improvedevice functionalityVSAvoidadaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The cartridge is designed with universal adaptability to work with different TPA fuse types and configurations. The standardized cartridge interface allows it to be used in various power distribution panel configurations without being restricted to proprietary form factors, thereby enhancing adaptability while maintaining functional reliability.

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

Solution Approach 2:

The cartridge is designed as a removable and replaceable component, allowing dynamic reconfiguration of the power distribution system. Users can easily swap cartridges to adapt to different power distribution needs without being constrained by fixed proprietary designs, thereby improving system versatility and adaptability.

Inventive Principle:
Principle #15Dynamics

AI summary

An overcurrent protection device for distributing power to a component. A cartridge may removeably receiving a TPA fuse. The cartridge may include a power input terminal and a power output terminal. When the cartridge is removeably received by a power distribution panel the power input terminal may directly couple to a power input connection of the power distribution panel and the power output terminal may directly couple to a power output connection of the power distribution panel. The directly coupled power input terminal and power output terminal being void of an intermediate busbar arranged between the cartridge and the power distribution panel.
