Lockable Fuse Holder for Power Outlet Current Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no known device or system that limits the amount of electrical power allocated to individual outlets or groups of outlets in convention centers, leading to potential overloading of the master power distribution system and unauthorized use of electricity.
Innovation Solution
A lockable electrical power control device connected to a master power distribution system that limits current supply using a fuse holder with a locking mechanism, where a fuse breaks if the power usage exceeds the allotted amperage, and an indicator light shows when electricity ceases to flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a master power distribution system supplies electrical power to multiple exhibitors without individual outlet control, then the system is simple and easy to operate, but exhibitors may overload the system or use more power than paid for
Solution Approach 1:
The invention divides the master power distribution system into individual controllable outlets, each with its own fuse holder and locking mechanism. This segmentation allows independent control and monitoring of power consumption at each outlet while maintaining overall system reliability.
Solution Approach 2:
The fuse is installed and locked in place before power distribution begins, establishing predetermined current limits for each outlet. This preliminary action prevents overloading and unauthorized power use before they can occur, rather than reacting to problems after they arise.
2Reliability
If individual outlet power limits are enforced using fuses, then power overload is prevented, but the system becomes more complex and difficult to maintain
Solution Approach 1:
The fuse holder is designed as a separate, extractable component that can be removed from the outlet without affecting other parts of the system. When a fuse blows, only that specific fuse needs to be extracted and replaced, simplifying maintenance and repair operations while maintaining circuit protection.
Solution Approach 2:
The locking mechanism automatically secures the fuse in place and provides visual indication through an LED when power is available or interrupted. This self-service feature reduces the need for manual monitoring and complex maintenance procedures.
3Reliability
If access to fuse holders is unrestricted, then the system is easy to maintain, but exhibitors can tamper with or bypass power limits
Solution Approach 1:
A locking mechanism acts as an intermediary between the fuse holder and unauthorized access. The lock prevents tampering while allowing authorized personnel to replace fuses using a key, thus maintaining both security and operational capability without compromising reliability.
4Loss of information
If power strips are provided without individual outlet monitoring, then the system is simple to deploy, but exhibitors cannot be held accountable for their specific power consumption
Solution Approach 1:
An LED indicator provides visual information about power availability and consumption status at each outlet. The LED changes state (on/off) to indicate whether power is available or has been interrupted due to overcurrent, enabling easy monitoring and accountability without complex electronic monitoring systems.

Function Achieved in This Case
Prevents overloading of the master power distribution system and ensures exhibitors only use the electricity they have paid for by limiting power usage and alerting authorities to unauthorized usage.
Implementation Method 1
a fuse breaks if the power usage exceeds the allotted amperage
Implementation Method 2
an indicator light shows when electricity ceases to flow

AI summary
Devices, systems and methods for regulating the distribution of electricity at events such as trade shows to prevent exhibitors from utilizing electricity not purchased from the convention center or other entity controlling electricity distribution, including lockable electric outlet boxes having a lockable fuse holder containing a fuse that restricts or limits a specific electrical outlet box or group of outlet boxes to a maximum electrical current or amperage.
