Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices such as mobile phones and tablets experience signal interference due to conductive substrates like metals and carbon fiber composites, which affect the performance of their antenna systems.
Innovation Solution
A flexible antenna belt made of non-impact antenna radiation materials, such as PTFE-coated aramid synthetic fibers, is introduced to reduce signal interference. This belt can form a continuous loop or sheet and includes rollers for rotation, with an optional antenna slot to allow wireless signals to pass through, and is integrated with a transparent antenna cover to enhance signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conductive substrates like metals and carbon fiber composites are used in computing devices, then structural strength and durability are improved, but signal interference with antenna systems increases
Solution Approach 1:
A flexible antenna belt made of non-conductive material (PTFE-coated aramid synthetic fibers) is introduced as an intermediary layer between the conductive substrate and the antenna system. This belt acts as a mediator that prevents direct interaction between conductive elements and antenna signals, thereby reducing signal interference while allowing the conductive substrate to maintain its structural function
Solution Approach 2:
The antenna belt is constructed from composite materials - specifically PTFE (polytetrafluoroethylene) coated aramid synthetic fibers. This composite structure combines the non-conductive properties of PTFE with the structural integrity of aramid fibers, creating a material that provides both mechanical strength and electromagnetic isolation
2Reliability
If a flexible antenna belt is introduced to reduce signal interference, then antenna performance is improved, but device complexity increases
Solution Approach 1:
The antenna belt is designed as a flexible thin film that can be easily integrated into the device structure. Its flexibility allows it to conform to various device geometries and be installed in thin profiles, minimizing the increase in device complexity while maintaining its function of reducing signal interference and improving antenna performance
