Solution Overview
Problem
Vehicles lack effective communication methods to maintain reliable wireless connections with target vehicles, especially when position changes affect signal intensity, leading to disrupted communication.
Innovation Solution
A vehicle equipped with a wireless communication device that forms and adjusts beam patterns based on the position of target vehicles to maintain communication, using a position detector and beam forming module to reacquire and update position information and adjust beam patterns accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed beam pattern is used for wireless communication, then the communication setup is simple, but the communication reliability deteriorates when the target vehicle moves
Solution Approach 1:
The beam pattern is made dynamic by continuously adjusting its direction based on the real-time position of the target vehicle. The wireless communication device monitors position information and reform s the beam pattern accordingly, transforming a static communication system into a dynamic one that adapts to moving targets, thereby maintaining communication reliability.
Solution Approach 2:
The system implements feedback by using position information of the target vehicle to control beam pattern adjustment. The position detector provides continuous feedback about the target's location, and the wireless communication device uses this feedback to adjust the beam direction, creating a closed-loop control system that maintains optimal communication.
2Reliability
If the beam pattern is continuously adjusted to track the target vehicle, then communication reliability is improved, but the energy consumption increases
Solution Approach 1:
Instead of continuous adjustment, the system performs beam pattern reforming at periodic intervals based on position updates. The beam pattern is adjusted when position information changes significantly, rather than continuously, reducing energy consumption while maintaining communication reliability through periodic tracking.
3Reliability
If the wireless communication device uses high signal intensity to maintain connection, then communication reliability is improved, but other vehicles may receive the signal causing interference
Solution Approach 1:
The beam pattern concentrates signal energy in a specific directional beam toward the target vehicle rather than radiating uniformly in all directions. This creates local quality by directing communication resources specifically to the intended recipient, improving signal intensity for the target while reducing interference to other vehicles in different directions.
Solution Approach 2:
The directional beam is dynamically adjusted to track the target vehicle's position, maintaining focused signal concentration on the intended recipient. This dynamic directional focusing ensures that high signal intensity is applied only where needed, preventing widespread interference while maintaining reliable communication.
