Building Door Fitting Antenna Integration with Segmented Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building door fittings with integrated antennas face challenges in minimizing signal damping and protecting the antenna from environmental influences like dirt and moisture, while maintaining a simple design and allowing for easy cleaning and flat integration into doors.
Innovation Solution
The antenna is housed within a carrier that is open on both sides, covered by a screen element and a cover element, allowing for a planar configuration that reduces signal interference and protects the antenna from environmental factors, with the option to embed the fitting flat into a building door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the antenna is arranged in a bulge of a fitting body made of plastic, then the antenna is protected from environmental influences, but the fitting body becomes uneven and difficult to clean
Solution Approach 1:
The fitting body is divided into separate components: a planar base structure and a removable cover element that encloses the antenna. This segmentation allows the main body to remain flat and easy to clean, while the cover provides protection for the antenna without creating surface irregularities on the cleaning surfaces.
Solution Approach 2:
A cover element is introduced as an intermediary component between the antenna and the external environment. This cover element protects the antenna from environmental influences while being separable from the main fitting body, thus maintaining the flat, easy-to-clean surface of the primary structure.
2Object-affected harmful factors
If the antenna is arranged in a bulge of a fitting body, then the antenna is protected from environmental influences, but the fitting body cannot be embedded flat in a building door
Solution Approach 1:
The protective enclosure for the antenna is segmented from the main fitting body. The base structure remains flat and planar for proper embedding into building doors, while the cover element is a separate component that provides protection without adding bulk to the embedding surface.
Solution Approach 2:
The cover element functions as a protective shell that encloses the antenna while maintaining a thin profile. This shell structure provides environmental protection without creating significant protrusions, allowing the fitting body to be embedded flat in building doors.
3Object-affected harmful factors
If the carrier is covered completely, then the antenna is protected from environmental influences, but signal reception is damped
Solution Approach 1:
The cover element is designed with local quality variations: it is made of electrically non-conductive material in areas where it contacts or approaches the antenna, and may have gaps or openings in other areas. This allows the cover to provide environmental protection while maintaining signal reception quality by preventing electromagnetic damping.
