Solution Overview

Problem

Current electronic devices face challenges in efficiently managing both short-range and long-range wireless communications using multiple frequency bands simultaneously, leading to suboptimal data transmission efficiency due to limitations in frequency band utilization.

Innovation Solution

An electronic device is equipped with multiple wireless communication circuits (e.g., WiFi and WiGig) and a processor that dynamically selects the appropriate frequency band for communication based on availability, establishing connections using the first frequency band if the second band is not accessible, and switching to the second band when possible for higher data rates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple wireless communication circuits for different frequency bands are equipped, then communication versatility is improved, but device complexity increases

Engineering Contradiction:
Improvecommunication versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by equipping the electronic device with multiple wireless communication circuits that support different frequency bands (first frequency band and second frequency band). Each communication circuit is configured to perform wireless communication with external electronic devices using its respective frequency band, enabling the device to adapt to various communication scenarios and requirements without needing separate dedicated systems for each band.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If dynamic frequency band selection is implemented, then data transmission efficiency is improved, but connection establishment time increases

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidconnection establishment time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by having the processor determine in advance whether a wireless connection can be established using the second frequency band before actually establishing the connection. This preliminary determination allows the system to prepare for high-speed communication when conditions are favorable while avoiding unnecessary connection establishment attempts when the second frequency band is unavailable, thus optimizing both efficiency and time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements dynamics through the processor's ability to dynamically select which frequency band to use for wireless communication based on real-time availability and connection conditions. The system can switch between the first frequency band and second frequency band depending on whether the second band is suitable for connection, enabling adaptive optimization of data transmission efficiency without being locked into a single fixed band.

Inventive Principle:
Principle #15Dynamics

3Reliability

If connection establishment checks are performed for multiple frequency bands, then communication reliability is improved, but processing time increases

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

Solution Approach 1:

The patent applies feedback by having the processor continuously monitor and determine whether a wireless connection can be established using the second frequency band based on current communication conditions. This feedback mechanism allows the system to adapt its connection strategy in real-time, selecting the most reliable frequency band available while avoiding unnecessary processing time by stopping the determination process when the second frequency band is confirmed to be unsuitable.

Inventive Principle:
Principle #23Feedback
