Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional local convergence points (LCPs) for multi-dwelling units (MDUs) are large, expensive, and require skilled technicians for installation and maintenance, and often lack flexibility for multiple optical connection types.
Innovation Solution
A cable entry apparatus with a housing comprising a first and second portion, allowing 90-degree rotational symmetry for different cable entry configurations, including dummy plugs, direct access, and connector patch panels, enabling easy installation and use by unskilled technicians.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional LCPs are used to service high density MDUs, then the number of subscribers serviced is improved, but the size and cost of the LCP increases
Solution Approach 1:
The LCP is divided into multiple modular slots (e.g., 12 slots) that can be independently configured. Each slot can accommodate different cable entry apparatuses or optical components, allowing the system to service multiple subscribers through modular expansion rather than requiring a single large monolithic structure.
Solution Approach 2:
The LCP design incorporates universal mounting structures and standardized interfaces that allow the same physical platform to service different numbers and types of subscribers. The modular slots can be configured for various optical connection types, making the LCP adaptable to different subscriber densities and connection requirements without changing the base structure.
2Quantity of substance
If conventional LCPs are used for high density MDUs, then the number of subscribers serviced is improved, but the installation complexity increases
Solution Approach 1:
The cable entry apparatus is segmented into standardized modular components that can be independently installed and configured. Each module handles specific cable entry functions, allowing technicians to install and service individual units without affecting the entire system, thereby reducing overall installation complexity despite serving more subscribers.
Solution Approach 2:
The system uses standardized interface parameters and mounting configurations that remain consistent across different subscriber densities. This standardization allows the same installation procedures to be applied regardless of the number of subscribers, reducing the complexity increase that would normally accompany higher subscriber counts.
3Adaptability or versatility
If multiple different types of optical connections are provided, then the versatility of the LCP is improved, but the number of different apparatuses required increases
Solution Approach 1:
The LCP employs universal mounting slots and standardized interfaces that can accommodate multiple types of optical connection apparatuses within the same physical platform. Different cable entry configurations (dummy plugs, direct access, connector patch panels) can be installed in different slots, allowing the system to provide versatile optical connections without requiring separate dedicated structures for each connection type.
Solution Approach 2:
Different optical connection types are segmented into separate modular apparatuses that can be independently selected and installed in specific slots based on the required connection type. This segmentation allows versatility through customization while maintaining simplicity through modular standardization, as each module handles one specific function.
4Reliability
If conventional LCPs are used, then optical fiber connectivity is provided, but the requirement for skilled technicians increases
Solution Approach 1:
The optical connection system is segmented into pre-configured modular units with standardized interfaces. Each module is designed to be self-contained with clear installation procedures, allowing technicians to install and service optical connections without requiring advanced splicing skills. The modular design maintains connectivity reliability through standardized interfaces while reducing the skill barrier for installation and maintenance.

AI summary
An apparatus for use in connection with an enclosure is provided herein. The apparatus comprises a housing comprising a first portion and a second portion coupled at a base. The first portion comprises a closed surface extending between a first edge and a second edge. The second portion comprises at least one opening extending between a third edge and a fourth edge. Each of the first edge, the second edge, the third edge, and the fourth edge define an edge profile, configured to provide selective (e.g., rotational insertion) coupling with the enclosure for controlling cable entry into the enclosure.
