Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio communication devices face challenges in efficiently switching between operation modes to optimize transmission quality, as testing alternative modes can degrade performance and is often inefficient, especially in scenarios where movement or changing conditions require frequent adjustments.
Innovation Solution
Incorporating a movement characteristics determination circuit, a beam pattern determination circuit, and an antenna controller to dynamically adjust antenna beam patterns based on the device's movement characteristics, allowing for adaptive selection between narrow and wide beams to optimize transmission quality without unnecessary mode switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radio communication device switches operation modes to find a better operation mode, then transmission quality may be improved, but performance may be degraded during the switching process and testing
Solution Approach 1:
The patent applies dynamics by making the beam pattern adjustable and adaptable based on movement characteristics. The antenna system dynamically switches between different beam patterns (first, second, third patterns) according to the detected movement state, allowing the system to optimize transmission quality without requiring full operation mode switching that degrades performance.
Solution Approach 2:
The patent changes the beam pattern parameter based on movement characteristics detection. By detecting whether the device is stationary or moving, the system selects appropriate beam patterns (narrower for stationary, wider for moving), thereby optimizing transmission quality through parameter adjustment rather than through costly operation mode switching.
2Reliability
If the radio communication device uses a fixed beam pattern, then device complexity is reduced, but transmission quality cannot be optimized for changing conditions
Solution Approach 1:
The patent applies local quality by using different beam patterns for different operational contexts (stationary vs. moving states). Instead of using a single uniform beam pattern, the system selects specific beam patterns based on the local condition (movement characteristics), thereby optimizing transmission quality for each specific situation without requiring complex adaptive algorithms.
Solution Approach 2:
The system performs self-service by automatically detecting movement characteristics and selecting appropriate beam patterns without external intervention. The movement characteristics determination circuit and antenna controller work autonomously to adapt the beam pattern, reducing the need for complex user-facing controls while maintaining optimization capability.
3Adaptability or versatility
If the radio communication device performs frequent operation mode switching to adapt to changing conditions, then adaptability is improved, but transmission quality may decrease due to frequent switching
Solution Approach 1:
The patent implements dynamics by enabling the antenna system to adapt to changing conditions through movement-based beam pattern selection. The system detects movement characteristics and dynamically adjusts the beam pattern accordingly, providing adaptability to different operational states (stationary vs. moving) without requiring frequent operation mode switching that would degrade transmission quality.
