Adjustable Barrier for Electrical Distribution Apparatus Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical distribution apparatuses face challenges in restricting access to electrically charged components during operation, leading to increased manufacturing and assembly costs due to regulatory requirements.
Innovation Solution
A removable and adjustable barrier is integrated into the electrical distribution apparatus, allowing selective access to power connectors by switching between different configurations, and removable shields can be coupled to further restrict access without the need for tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access to power connectors is restricted during operation, then safety is improved, but manufacturing and assembly costs increase
Solution Approach 1:
The barrier is divided into multiple positionable configurations that can be selectively positioned to restrict access to different power connectors. This segmentation allows the same barrier structure to serve multiple safety functions while maintaining cost-effectiveness through a single reusable component rather than multiple fixed barriers.
Solution Approach 2:
The barrier is designed with the capability to be repositioned between different configurations, transforming it from a static safety component to a dynamic one. This dynamic feature allows the barrier to adapt to different operational states (forward feed vs. reverse feed), providing continuous safety protection while using a single versatile component that reduces manufacturing costs.
2Reliability
If fixed barriers are used to restrict access to power connectors, then safety is improved, but assembly time and complexity increase
Solution Approach 1:
The barrier is designed as a dynamic component that can be quickly repositioned between different configurations during assembly and operation. This eliminates the need for multiple fixed barriers, reducing assembly time while maintaining safety through a single adaptable component that can be rapidly reconfigured.
3Adaptability or versatility
If multiple fixed barriers are installed to accommodate different cable connection configurations, then all connection options are supported, but device complexity and cost increase
Solution Approach 1:
The barrier is designed as a universal component that can perform multiple functions by being positioned in different configurations. A single barrier structure can restrict access to different power connectors depending on the operational mode, eliminating the need for multiple specialized barriers and reducing overall device complexity while maintaining full adaptability.
Solution Approach 2:
The dynamic repositioning capability of the barrier allows it to adapt to different cable connection configurations (forward feed, reverse feed, different terminals) without requiring multiple fixed barriers. This single dynamic component replaces what would otherwise require several static barriers, simplifying the device structure.

AI summary
An electrical distribution apparatus includes a power connector for coupling to a cable. The power connector includes a first end and a second end each defining an opening arranged to receive the cable. A barrier is removably coupled to a portion of the electrical distribution apparatus and selectively adjustable between a first position and a second position, the barrier arranged to prevent insertion of the cable into the first end opening and to permit insertion of the cable into the second end opening when the barrier is in the first position, the barrier arranged to prevent insertion of the cable into the second end opening and to permit insertion of the cable into the first end opening when the barrier is in the second position.
