Modular RF Port Expansion With Minimal Footprint Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RF devices require users to either replace them with larger models or add expansion modules, leading to increased spatial footprint and inventory costs, as they lack modular expansion capabilities that allow for easy upgrading without disrupting existing connections.
Innovation Solution
A modular passive MoCA apparatus with a passive RF portal and expansion module that can be removably coupled, allowing users to expand output ports without significantly increasing the device's spatial footprint, while maintaining easy access to all ports and enabling upgrades without disrupting connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users replace RF devices with larger models to increase output ports, then the number of output ports increases, but the spatial footprint and device cost increase
Solution Approach 1:
The RF device is divided into a base unit and separate expansion modules. Each expansion module contains additional output ports and can be attached to the base unit, allowing users to increase the number of output ports without replacing the entire device with a larger model. This segmentation enables incremental expansion while maintaining a compact base unit footprint.
Solution Approach 2:
The expansion modules are designed to attach to the base unit in a nested configuration, where the module integrates with the existing device structure. This nesting approach allows the expanded functionality to be accommodated within or adjacent to the original device boundaries, minimizing the increase in spatial footprint.
2Adaptability or versatility
If users replace RF devices with larger models to increase output ports, then the number of output ports increases, but device cost increases
Solution Approach 1:
The device is segmented into a base unit and modular expansion components that can be manufactured separately and assembled. This allows suppliers to produce a standardized base unit at a lower cost and offer expansion modules as optional add-ons, rather than manufacturing and inventorying multiple complete device variants with different port configurations.
Solution Approach 2:
The base unit is designed with universal attachment interfaces that can accommodate different expansion modules. This universality allows a single base unit design to support multiple configuration options, reducing the need to manufacture and stock multiple specialized device models, thereby lowering overall device cost.
3Adaptability or versatility
If suppliers maintain inventory of numerous sized RF devices to cover user needs, then user requirements are met, but inventory costs increase
Solution Approach 1:
Instead of maintaining inventory of complete RF devices in various sizes, suppliers only need to stock the standardized base unit and a limited set of expansion modules. This segmentation of the product line allows flexible configuration to meet different user requirements while dramatically reducing the total inventory quantity and associated costs.
Solution Approach 2:
The variable component (number of output ports) is extracted from the base device and implemented as separate expansion modules. This extraction allows suppliers to maintain a simple, standardized base unit inventory and add functionality through optional modules, rather than maintaining complex inventory of pre-configured devices with different port counts.
4Adaptability or versatility
If users add expansion modules to increase output ports, then the number of output ports increases, but the spatial footprint increases
Solution Approach 1:
The expansion module is designed to nest onto the base unit with interlocking interfaces that minimize the overall volume increase. The module attaches in a way that allows it to share space with the base unit structure, rather than requiring completely separate mounting space, thereby minimizing the spatial footprint increase.
Solution Approach 2:
The expansion module utilizes vertical or depth-oriented attachment rather than purely horizontal expansion. By attaching the module to the top or side of the base unit in a vertical dimension, the horizontal footprint is minimized while still providing access to additional ports through strategic port orientation and cable management.

AI summary
A modular RF apparatus includes an RF portal and an RF expansion module configured to be coupled with the RF portal. The modular RF apparatus is configured to expand the number of outputs of the RF portal by adding the RF expansion module in a manner that minimizes an increase in the spatial footprint of the modular RF apparatus while allowing easy access to all ports of the modular RF apparatus. The RF portal and the RF expansion module are configured to interlock to create an integrated functional block. The modular RF apparatus are configured to permit upgrading of the RF portal by adding the RF expansion module without disrupting existing connections to the RF portal.
