Solution Overview
Problem
Modular electrical systems in work areas require skilled labor for installation, reconfiguration, and relocation due to the need for hard-wired electrical power supplies, limiting flexibility and safety.
Innovation Solution
A plug-in power distribution unit that connects directly to conventional electrical outlets, eliminating the need for hard-wired installations and featuring proprietary output connectors for compatibility and safety, allowing easy relocation by unskilled labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hard-wired electrical power supply is used, then electrical power distribution is reliable, but installation and relocation require skilled labor and are difficult
Solution Approach 1:
The patent introduces a mounting bracket as an intermediary component between the power distribution unit and the electrical outlet. The bracket provides a secure mechanical attachment mechanism that simplifies installation and relocation while maintaining reliable electrical connections through the plug interface.
Solution Approach 2:
The power distribution unit is designed as a separate, self-contained module that can be independently installed and relocated. This segmentation allows the unit to be easily moved without affecting the building's hard-wired electrical infrastructure, while still providing reliable power distribution through standardized plug connections.
2Adaptability or versatility
If conventional electrical outlets are used, then power distribution is flexible and relocatable, but risk of electrical overload increases
Solution Approach 1:
The patent incorporates circuit breakers and overcurrent protection devices within the power distribution unit before power is distributed to outlets. These protective mechanisms are pre-installed and automatically activate to prevent electrical overload, addressing the safety concern before it can cause harm while maintaining the flexibility of plug-in operation.
Solution Approach 2:
The circuit breakers provide automatic feedback control by monitoring current draw and interrupting power flow when overload conditions are detected. This feedback mechanism prevents electrical hazards while allowing the system to remain flexible and relocatable, as the protection is built into the portable unit itself.
3Reliability
If proprietary connectors with keying features are used, then safety against electrical overload is improved, but device complexity increases
Solution Approach 1:
The patent employs asymmetric keying features on connectors to prevent incompatible devices from being connected. The keying mechanism uses simple geometric asymmetry (such as offset positions or specific shapes) rather than complex mechanical interlocks, providing effective overload protection while minimizing added complexity in the connector design.

AI summary
A plug-in power distribution unit is readily installable, removable, and replaceable by skilled or non-skilled persons. The units include one or more conventional electrical power plugs for engaging a conventional wall outlet or the like, and one or more proprietary electrical power connectors for engaging with a compatible connector of a modular electrical power system. Optionally, multiple circuits may be accommodated by the plug-in power distribution unit.
