Solution Overview

Problem

Existing Wi-Fi connection systems face limitations in transmission throughput due to contention-based protocols when multiple devices communicate with a network access point in the same frequency band.

Innovation Solution

A multi-device system and method that allows for establishing wireless connections in different frequency bands based on the availability of single-band or multi-band communication with a network access device, optimizing data transmission by allocating larger bandwidths for devices requiring mass data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple devices communicate with a network access point in the same frequency band through a contention-based protocol, then the system can maintain simplicity in connection management, but the transmission throughput is limited due to sequential access requirements

Engineering Contradiction:
Improvetransmission throughputVSAvoidconnection management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the frequency spectrum into multiple frequency bands (e.g., 2.4GHz, 5GHz, 6GHz) and assigns different devices to different bands. This segmentation allows simultaneous data transmissions without contention, as each band operates independently. The network access point and electronic devices are divided into multiple groups based on their frequency band assignments, enabling parallel communication channels that dramatically improve overall transmission throughput.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from single-dimensional communication (one frequency band) to multi-dimensional communication (multiple frequency bands). By adding the frequency band dimension, the system creates multiple independent communication planes where data can be transmitted simultaneously. This dimensional expansion allows the network to handle multiple devices in parallel rather than sequentially, resolving the throughput limitation while maintaining manageable complexity through automated band selection.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a host device transmits data with two devices in the same frequency band, then the connection setup remains simple, but the host device cannot perform data transmission with one device until transmission with the other device is completed

Engineering Contradiction:
Improvedata transmission capabilityVSAvoidtransmission waiting time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent segments the communication channel by assigning different frequency bands to different device pairs. When the host device needs to communicate with multiple devices, each device is assigned to a different frequency band, creating separate communication channels. This allows the host device to transmit data with multiple devices simultaneously without waiting for one transmission to complete before starting another, thereby eliminating transmission waiting time while maintaining ease of operation through automated channel management.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The network access point acts as an intermediary that manages frequency band allocation and coordination. It automatically assigns appropriate frequency bands to different device pairs and handles the complexity of multi-band communication, allowing host devices to communicate simultaneously without direct interference management. This intermediary approach maintains ease of operation for end devices while eliminating transmission waiting time through coordinated multi-band access.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the network access device supports multi-band communication, then simultaneous data transmission among multiple devices is enabled, but the system requires more complex frequency band selection and management

Engineering Contradiction:
Improvesimultaneous transmission capabilityVSAvoidfrequency band management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements self-service mechanisms where electronic devices automatically determine their own frequency band assignments based on network conditions and device capabilities. Devices autonomously select appropriate frequency bands without requiring manual configuration or complex centralized scheduling. This self-service approach enables simultaneous multi-band transmissions while keeping frequency band management complexity low, as the automation handles the coordination overhead.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent dynamically changes communication parameters such as frequency band selection, transmission power, and modulation schemes based on real-time network conditions. The network access point and devices adapt their operating parameters to optimize performance, selecting from multiple available frequency bands and configurations. This parameter flexibility enables simultaneous transmissions while managing complexity through adaptive algorithms that automatically adjust to current conditions rather than requiring fixed complex management structures.

Inventive Principle:
Principle #35Parameter changes
