Antenna Extension Device for Signal Transmission Through Building Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home intelligent networks face challenges in receiving and transmitting radio signals due to signal blockage by building walls and obstructions, which can lead to missed alerts and delayed responses in security and monitoring systems.
Innovation Solution
An antenna extension device with a U-shape or L-shape cross-sectional profile is placed between a building opening and a panel, comprising three parts: one on the inner surface, one in the space between the opening and panel, and one on the outer surface, connected to a sensing device, to facilitate unobstructed radio wave transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio signals are transmitted through building walls and obstructions, then outdoor range coverage is achieved, but signal strength is largely reduced and signals are missed
Solution Approach 1:
The patent introduces an antenna extension device as an intermediary component installed at building openings (doors/windows) to mediate radio signal transmission between indoor and outdoor environments. This device includes conductive parts that extend through the building opening, creating a transmission path that bypasses the signal-blocking walls while maintaining signal strength, thus resolving the contradiction between achieving outdoor coverage and maintaining signal reliability.
2Strength
If walls and obstructions are used for building structure, then building integrity is maintained, but radio signal transmission is blocked
Solution Approach 1:
The patent segments the building structure by creating a dedicated signal transmission path through the building opening (door/window) that is separate from the main wall structure. The antenna extension device is divided into multiple parts (indoor portion, outdoor portion, and connection section) that collectively form a complete transmission path, allowing signal transmission without compromising the structural integrity of the building walls.
3Reliability
If antenna extension device is added to facilitate signal transmission, then radio wave transfer is enhanced, but device complexity increases
Solution Approach 1:
The antenna extension device is designed to be universally applicable to different building openings (doors and windows) and can serve multiple functions: signal transmission, structural support, and integration with existing building elements. The device's conductive parts can be configured in different patterns (e.g., grid structures) that serve both electromagnetic shielding and mechanical support functions, reducing overall system complexity while maintaining transmission reliability.

AI summary
An antenna extension device includes a first part disposed on an inner surface of a panel; a second part disposed in space between an opening of a building and the panel, the opening correspondingly accommodating the panel; and a third part disposed on an outer surface of the panel. Two ends of the second part are connected to the first part and the third part respectively to form a U-shape cross-sectional profile, and the third part is connected to a feed point of a sensing device.
