Blind Drive Assembly Antenna Sealing via Permeable Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for concealing openings in buildings or providing solar protection controlled by radio waves face challenges due to the need for antennas to be placed outside winding tubes made of materials that strongly attenuate radio waves, leading to sealing issues, increased complexity, and bulkiness.
Innovation Solution
A drive assembly with a motor, electronic module, and radio module is integrated within a first tube, using a permeable fixing element with an antenna to transmit or receive radio waves, positioned optimally to avoid metal structures and materials that block radio waves, and connected via a coaxial cable, ensuring sealing and mechanical protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is placed outside the winding tube, then radio wave transmission is possible, but dust and liquid tightness cannot be guaranteed
Solution Approach 1:
The antenna is integrated into the fixing element that secures the first tube to the frame support, merging the antenna structure with the mounting structure. This allows the antenna to be positioned outside the winding tube for radio wave transmission while the fixing element provides sealing against dust and liquids.
Solution Approach 2:
The fixing element acts as an intermediary structure that houses the antenna while providing the seal between the first tube and the frame support. This intermediary structure resolves the conflict between needing the antenna outside the tube and maintaining dust/liquid tightness.
2Reliability
If the antenna is placed outside the winding tube, then radio wave transmission is possible, but the installation complexity increases
Solution Approach 1:
By merging the antenna with the fixing element, the number of separate components is reduced. The antenna is no longer a separate piece requiring individual installation, but is integrated into the mounting structure, simplifying the installation process.
3Reliability
If the antenna is placed outside the winding tube, then radio wave transmission is possible, but the space requirement increases
Solution Approach 1:
The fixing element serves multiple functions: it secures the first tube to the frame support, houses the antenna, and provides sealing. This multi-functionality eliminates the need for separate antenna housing structures, reducing the overall space requirement.
4Ease of manufacture
If the antenna is integrated inside the first tube, then sealing is simplified, but radio wave transmission is blocked
Solution Approach 1:
The antenna is positioned in a different spatial dimension - in the fixing element at the end of the first tube rather than inside the tube. This dimensional change allows the antenna to be outside the radio wave blocking tube while the fixing element provides the necessary sealing.
