Interlocking Device for Multi-Enclosure Door Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Enclosures for electrical distribution systems lack effective interlocking mechanisms to ensure safe and secure access while maintaining the integrity of electrical components and preventing unauthorized contact with electric power.
Innovation Solution
An interlocking device that connects multiple enclosure doors through a cable actuator and linkage system, allowing selective locking and unlocking of doors and controlling the flow of electric power, ensuring secure access and operation while isolating electrical components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple enclosure doors are independently locked, then each door can be accessed separately for maintenance, but security and safety are compromised due to lack of coordinated control
Solution Approach 1:
The patent combines multiple independent door locking mechanisms into a single integrated interlocking device that controls all doors simultaneously. The device includes a central actuator that operates multiple locking points across different enclosure doors, ensuring they are either all locked or all unlocked together, thus maintaining security while enabling coordinated maintenance access.
Solution Approach 2:
The interlocking device employs dynamic control where the locking state of multiple doors is changed simultaneously through a single actuation event. The mechanism allows the system to transition between locked and unlocked states dynamically, ensuring that doors remain securely locked during normal operation and can be unlocked together when maintenance is required.
2Reliability
If an interlocking device connects multiple enclosure doors, then security and safety are improved by preventing unauthorized access, but device complexity increases due to additional interlocking components
Solution Approach 1:
The interlocking device is designed as a universal mechanism that can control multiple different types of enclosure doors through a single system. The device includes adaptable locking components that can interface with various door types and configurations, reducing the need for separate specialized locking mechanisms for each door and thereby simplifying the overall system while maintaining security.
3Ease of manufacture
If the interlocking device uses a cable actuator system to connect enclosures, then ease of installation is improved, but manufacturing precision requirements increase to ensure proper cable routing through boundaries
Solution Approach 1:
The cable actuator system serves as an intermediary mechanism that connects the interlocking device across enclosure boundaries without requiring direct mechanical connection between enclosures. The cable passes through defined routing paths and apertures in the enclosure boundaries, providing flexible connection while maintaining the integrity and sealing of each enclosure. The cable routing includes guides and protective conduits that ensure proper alignment and reduce precision requirements.

AI summary
An enclosure assembly includes a plurality of enclosures. Each enclosure of the plurality of enclosures includes a cabinet including an interior surface defining an interior volume, and a door mounted relative to a respective opening of each cabinet. An interlocking device interlocks a first door of a first enclosure of the plurality of enclosures, a second door of a second enclosure of the plurality of enclosures, and a third door of a third enclosure of the plurality of enclosures. The interlocking device is operable to selectively fasten each of the first door, the second door, and the third door in a closed position.
