Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadband access systems face challenges with the location of user premises equipment, particularly the TX/RX antenna being outside the premises while the router is inside, and the lack of power availability outside the premises, along with interference from metallic elements.
Innovation Solution
A user premises system comprising an internal unit with a wireless power transmitter and an external modem unit with a wireless power receiver, both equipped with short-range transceivers, enabling inductive power transfer and data communication through an exterior structure, with magnetic coils aligned for unobstructed transmission and interference detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the TX/RX antenna is located outside the user premises, then satellite/cellular signal reception is improved, but power availability becomes problematic
Solution Approach 1:
The patent replaces traditional wired power delivery with wireless inductive power transfer. The internal unit uses electromagnetic induction to transmit power through the exterior structure wall to the external modem unit, eliminating the need for physical electrical connections outside the premises while enabling power supply to the externally located antenna.
Solution Approach 2:
The exterior structure wall serves as an intermediary medium through which both power and data are transferred. The inductive power transfer system uses the wall as a coupling medium between the internal power source and external power receiver, allowing energy transmission without direct electrical contact.
2Use of energy by moving object
If the router is located inside the user premises, then power availability is ensured, but proximity to exterior walls for antenna installation is reduced
Solution Approach 1:
The system divides the broadband equipment into separate functional units: an internal unit containing the power source and data network connection, and an external modem unit containing the antenna. This segmentation allows the antenna to be optimally positioned outside near the exterior wall for signal reception while the power-consuming components remain inside where power is available.
Solution Approach 2:
Wireless inductive power transfer replaces traditional cable-based power delivery, enabling the external modem unit to receive power through the wall without requiring long power cables or proximity to interior power outlets. This eliminates the constraint of cable length and routing complexity.
3Ease of manufacture
If power is transmitted through the exterior structure, then installation complexity is reduced, but interference from metallic elements may occur
Solution Approach 1:
The system incorporates detection mechanisms that monitor the power transfer path for metallic obstructions. When metallic elements are detected that would interfere with inductive power transfer or data communication, the system provides feedback to alert the user and guide repositioning of the units to achieve optimal alignment and avoid interference.
Solution Approach 2:
The system performs preliminary detection of the transmission path during installation to identify potential metallic interference before full operation begins. This allows users to adjust the positioning of internal and external units in advance to avoid problematic areas with metallic construction elements.
