Selective Antenna Allocation for Vehicle Transceivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing use of multiple dedicated antennas for each transceiver in vehicles leads to inefficiencies in space usage, increased costs, and reduced reliability, as well as the potential for all transceivers to become inoperable if one antenna is damaged.
Innovation Solution
Implementing a selective antenna allocation system that allows multiple transceivers to share a single antenna based on priority and vehicle operating mode, enabling efficient frequency management and redundancy in case of antenna failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple dedicated antennas are used for each transceiver, then each transceiver can operate independently and reliably, but the number of antennas, wiring, and space required increases
Solution Approach 1:
Multiple transceivers share a single antenna resource through selective allocation. The system combines multiple transceiver functions into one physical antenna, reducing the total number of antennas and wiring while maintaining operational reliability through intelligent resource management.
Solution Approach 2:
A single antenna is designed to serve multiple transceivers with different functions (WiFi, Bluetooth, cellular, etc.). The antenna becomes a universal resource that can be dynamically allocated to different transceivers based on priority and operational needs, eliminating the need for dedicated antennas for each transceiver type.
2Reliability
If multiple dedicated antennas are installed in the vehicle, then each transceiver has its own antenna, but the cost and space occupation increase
Solution Approach 1:
The system merges multiple antenna functions into a single shared antenna resource. By combining the antenna resources that would otherwise be dedicated to each transceiver, the total quantity of antennas and associated materials is reduced while maintaining communication reliability through selective allocation.
Solution Approach 2:
The single antenna is designed with universal capability to support multiple transceiver types. This multi-functional approach eliminates the need for separate antennas for WiFi, Bluetooth, cellular, and other transceivers, thereby reducing the total quantity of materials while preserving operational reliability.
3Device complexity
If a single shared antenna is used for multiple transceivers, then the number of antennas and costs are reduced, but conflicts may occur when multiple transceivers need the antenna simultaneously
Solution Approach 1:
The antenna allocation system dynamically adjusts which transceiver receives antenna access based on real-time priority levels and operational modes. Instead of static assignment, the system continuously monitors transceiver needs and reallocates the antenna resource dynamically, resolving conflicts through adaptive resource management.
Solution Approach 2:
The system implements feedback mechanisms where transceivers communicate their priority levels and operational status to the antenna allocation controller. This feedback enables the system to make informed allocation decisions, granting antenna access to high-priority transceivers (such as emergency cellular communications) while deferring lower-priority ones, thereby managing conflicts effectively.
4Device complexity
If multiple transceivers share one antenna, then costs and space are reduced, but the system may become inoperable if the single antenna fails
Solution Approach 1:
The system prepares backup antenna allocation strategies in advance. When antenna failure is detected, the system has pre-established alternative configurations and can rapidly switch to using different antenna elements or reconfiguring the existing antenna, thereby cushioning against the failure impact and maintaining operational reliability.
Solution Approach 2:
The antenna system is segmented into multiple independent elements or zones within the single antenna structure. This segmentation allows partial functionality to remain operational even if one segment fails, enabling the system to continue operating with reduced capacity rather than becoming completely inoperable.

AI summary
Examples of techniques for selective antenna allocation are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method may include receiving a first request for an antenna from a first transceiver. The method may further include receiving a second request for the antenna from a second transceiver. Additionally, the method may include selectively allocating the antenna to one of the first transceiver or the second transceiver based on the higher of a priority of the first transceiver and a priority of the second transceiver.
