Motorized Shade Antenna Bracket for Stable Radio Signal Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concealment devices with motorized drive systems face issues where the radio antenna is not properly maintained in position, leading to degraded radio signal performance and potential damage due to contact with metal surfaces or being dragged by the screen.
Innovation Solution
A support structure is introduced to house the radio antenna outside the trunk, maintaining it at a safe distance from metal surfaces and preventing damage, while ensuring optimal signal performance and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the radio antenna is left free outside the trunk without being held in position, then the device complexity is reduced, but the radio signal performance is degraded and the antenna may be damaged
Solution Approach 1:
A support structure acts as an intermediary element between the trunk and the radio antenna. The support comprises a housing that receives and holds the radio antenna in a fixed position outside the trunk, preventing it from contacting metal surfaces or being damaged by screen movement, while maintaining radio signal performance
Solution Approach 2:
The system is segmented into distinct functional components: the trunk containing the electronic control unit, the support structure housing the radio antenna, and the screen assembly. This segmentation allows the radio antenna to be positioned optimally for signal performance while being protected from damage
2Reliability
If the radio antenna is held in position outside the trunk using a support structure, then the radio signal performance is improved, but the device complexity increases
Solution Approach 1:
The support structure serves multiple functions simultaneously: it holds the radio antenna in position for optimal signal performance, protects the antenna from damage by screen movement and metal surface contact, and provides a mounting structure that can be attached to the trunk or building surface. This multi-functionality justifies the added structural complexity
3Device complexity
If the radio antenna is placed close to metal surfaces, then the device complexity is reduced, but the radio signal transmission and reception is degraded
Solution Approach 1:
The support structure with its housing acts as an intermediary that positions the radio antenna at an optimal distance from metal surfaces. The housing provides physical separation between the antenna and the trunk or building surface, ensuring adequate clearance for radio signal transmission while maintaining a compact overall structure
4Ease of manufacture
If the radio antenna is left exposed outside the trunk, then the ease of manufacture is improved, but the antenna may be damaged by screen movement or pulled away from the electronic control unit
Solution Approach 1:
The support structure provides beforehand protection for the radio antenna by enclosing it in a housing and securing it in a fixed position. This prevents the antenna from being damaged by screen movement, pulled away from the electronic control unit, or folded back on itself during operation
Solution Approach 2:
The support structure serves as a protective intermediary between the moving screen and the stationary radio antenna, preventing direct interaction that could cause damage to the antenna while allowing the screen to move freely
