Front Access Power Landing for Telecom Equipment Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing arrangement of power feeder cable connections within telecom equipment assemblies, located at the rear or top, makes it inconvenient and hazardous for operators to inspect and maintain the connections, requiring the use of ladders and increasing the risk of power loss or scorching due to loose connections.
Innovation Solution
Positioning the power landing or connector at a more accessible location, such as the side or front of the telecom equipment assembly, with a protective cover, and using a bus bar or L-shaped connector with a lug and nut configuration to secure the power feeder cable, allowing for easier access and maintenance without the need for ladders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power feeder cable connection is located inside or at the rear of the telecom equipment assembly, then the connection is protected and integrated into the equipment structure, but the access for inspection and maintenance becomes difficult and hazardous requiring step ladders
Solution Approach 1:
The power landing is repositioned from the traditional rear or internal location to the front or side of the equipment assembly, changing the spatial dimension of access. This allows operators to reach connections at waist level from the equipment aisle without requiring ladders or awkward positioning, directly resolving the accessibility hazard while maintaining connection integrity through proper mounting structures
2Device complexity
If the connection is located at the rear of the equipment assembly, then the equipment design follows conventional layout, but the operator must use a step ladder which is time consuming and presents safety hazards
Solution Approach 1:
The power landing is pre-positioned at an optimally accessible location on the equipment assembly during manufacturing or installation. This preliminary placement ensures that future maintenance operations can be performed immediately without requiring operators to set up ladders or reposition equipment, eliminating time loss and safety hazards associated with accessing rear-mounted connections
3Device complexity
If the connection is at the rear of the equipment assembly, then the internal wiring layout is simplified, but the operator faces potential hazards and requires safety precautions during maintenance
Solution Approach 1:
The power landing serves as an intermediary component that bridges the power feeder cable and the internal bus bar while being positioned at the front or side of the equipment. This intermediary placement allows the wiring layout to remain simplified internally while the power landing itself acts as a safely accessible interface point, eliminating operator exposure to electrical hazards and physical safety risks associated with rear-mounted connections
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances operator safety and efficiency by providing convenient access to the power connections, reducing the risk of power loss and scorching, while maintaining the necessary electrical resistance and integrity of the connections.
Implementation Method 1
The cables ('power feeder cables') connecting the battery room to the telecom equipment assemblies within the telecom equipment room must be capable of conducting low voltage, high amperage, DC power with minimal resistance
Implementation Method 2
the contact between the power feeder cable and the power entry point begins to deteriorate as the nut begins to loosen due to heating of the contact through the interaction of electricity flowing through the cable and electrical resistance between the contact
Implementation Method 3
Such heating results in the expansion of the components forming the contacts and ultimately loosening of the connection
