Solution Overview

Problem

Existing communication systems using millimeter waves struggle to quickly adapt frequency bands in response to environmental changes, leading to degraded communication quality due to obstacles or distance variations, necessitating a more rapid and adaptive frequency band switching mechanism.

Innovation Solution

A frequency band determination device and method that utilizes image acquisition and analysis to determine the frequency band based on the environment and relative position of communication devices, switching between millimeter and microwave bands to maintain optimal communication quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If millimeter waves are used for communication, then communication quality is high in line-of-sight conditions, but communication quality degrades rapidly when obstacles exist or distance increases

Engineering Contradiction:
Improvecommunication qualityVSAvoidenvironmental adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically switches between millimeter wave and microwave frequency bands based on real-time environmental conditions detected by the image acquisition section. When obstacles or distance changes are detected, the system transitions from static millimeter wave communication to adaptive microwave communication, resolving the contradiction between high communication quality and environmental adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the frequency band parameter from millimeter wave to microwave based on environmental conditions. This parameter change allows the system to maintain high communication quality in line-of-sight conditions while gaining adaptability to obstructed environments, effectively resolving the technical contradiction.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If frequency band switching is implemented based on radio wave condition monitoring, then communication quality can be maintained, but significant time delay occurs between environmental change and frequency band switching

Engineering Contradiction:
Improvecommunication qualityVSAvoidresponse time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The image acquisition section continuously captures environmental information in advance, allowing the system to detect obstacles or distance changes before they significantly impact communication quality. This preliminary detection enables proactive frequency band switching, reducing the time delay between environmental change and response.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback loop where the image acquisition section continuously monitors environmental conditions and provides real-time information to the frequency band determination section. This feedback mechanism enables rapid detection and response to environmental changes, minimizing the time delay in frequency band switching while maintaining communication quality.

Inventive Principle:
Principle #23Feedback

3Speed

If image acquisition and analysis is used to determine frequency band, then rapid response to environmental changes is achieved, but device complexity increases

Engineering Contradiction:
Improveresponse speedVSAvoidsystem complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The invention introduces an image acquisition section as an intermediary device that captures environmental information. This intermediary provides real-time environmental data to the frequency band determination section, enabling rapid response without significantly increasing overall system complexity, as the image acquisition function can be integrated into existing head-mounted display devices.

Inventive Principle:
Principle #24Intermediary (Mediator)
