Conductive Textile Antenna for Foldable Car2X Traffic Cones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna solutions for Car2X communication in foldable traffic cones, such as those made of textile fabric, face challenges in accommodating sufficient antenna size for adequate gain while maintaining foldability and avoiding damage to insulated stranded conductors.
Innovation Solution
Conductive filaments are woven into a carrier fabric to form a flexible antenna structure that can be configured as a contacting structure, allowing for foldability and protection against damage, with options for forming stranded, two-dimensional, or annular structures, and incorporating plug-in connectors or rivets for secure connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If insulated stranded conductors are used in foldable textile antennas, then the antenna can be made foldable and integrated into textile articles, but the conductors are susceptible to damage from catching, tearing, and mechanical stress during folding and unfolding
Solution Approach 1:
The patent replaces traditional insulated stranded conductors with conductive textile fabric that is inherently flexible and integrated into the carrier fabric. The conductive fabric behaves like a flexible thin film that can be folded, bent, and deformed without the mechanical weaknesses of stranded conductors, eliminating catching and tearing issues while maintaining electrical conductivity for antenna function
Solution Approach 2:
The patent creates a composite structure where conductive filaments or conductive fabric are integrated into a carrier fabric to form a unified conductive textile material. This composite approach combines the mechanical properties of textile fabric (flexibility, foldability, durability) with electrical conductivity, producing a material that simultaneously achieves adaptability for folding and reliability for mechanical durability
2Reliability
If the antenna size is increased to achieve adequate gain for Car2X communication, then the transmission performance is improved, but the foldability and space-saving storage capability are compromised
Solution Approach 1:
The patent employs a dynamic antenna structure made of conductive textile fabric that can change its configuration between folded and unfolded states. When unfolded, the antenna achieves sufficient size for adequate gain and transmission performance. When folded, it compactly stores in a space-saving manner. The dynamic reconfigurability allows the antenna to adapt its physical dimensions to meet different operational requirements
3Ease of manufacture
If traditional fixed antennas are used in traffic cones, then the antenna structure is simple and easy to manufacture, but the foldability and integration into textile fabric is not possible
Solution Approach 1:
The patent replaces rigid fixed antenna structures with flexible conductive textile fabric that can be integrated into the textile carrier of traffic cones. The conductive fabric maintains structural simplicity through direct integration into the existing textile construction, while simultaneously enabling foldability and flexibility that fixed antennas cannot achieve, allowing the traffic cone to be collapsed and stored
