Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional satellite terminal equipment is installed, then satellite internet service can be provided, but installation complexity increases and physical modifications to the building are required
Solution Approach 1:
The patent introduces a barrier (window glass) as an intermediary medium to transmit optical signals between the outdoor satellite terminal and indoor equipment, eliminating the need for physical penetration or complex installation while maintaining signal transmission capability
Solution Approach 2:
The patent replaces mechanical installation methods (drilling holes, running cables through walls) with optical transmission through existing transparent barriers, substituting physical modification with light-based signal transmission
2Reliability
If RF repeaters are used to improve indoor signal coverage, then indoor signal strength increases, but interference with outdoor satellite signals occurs
Solution Approach 1:
The patent substitutes RF signal transmission with optical signal transmission through the window barrier, eliminating RF interference issues while maintaining indoor signal coverage. The optical domain is used instead of the RF domain to avoid electromagnetic interference
Solution Approach 2:
The window glass acts as an intermediary that allows optical signals to pass through to provide indoor coverage without the need for RF repeaters, thereby avoiding the generation of harmful RF interference with outdoor satellite signals
3Reliability
If physical modifications are made to install satellite equipment, then satellite terminal functionality is achieved, but installation time and technical skill requirements increase
Solution Approach 1:
The existing window glass structure serves the dual purpose of being both a building component and a signal transmission medium, eliminating the need for separate installation infrastructure and reducing installation time and skill requirements

AI summary
A barrier mounted satellite gateway or terminal having an indoor unit to communicate with user equipment within a physical structure and an outdoor unit configured to communicate with one or more satellites. The indoor unit and outdoor unit may, respectively, be applied to the interior and exterior panes of a transparent or translucent barrier, e.g., a window, of the structure. The indoor and outdoor units may be in optical communication with each other via optical signals transmitted through the transparent or translucent barrier.
