Solution Overview

Problem

Existing methods for controlling electronic devices via a server incur increased communication costs and time when terminals are in close proximity, and may fail in environments without network connectivity.

Innovation Solution

The electronic device operates dual communication channels, allowing nearby terminals to control it directly through a reserved channel when connected to a peripheral device, and manages channel states based on user input and connection status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If control information is transmitted through a server, then the electronic device can be controlled remotely, but communication cost and time increase

Engineering Contradiction:
Improvecontrol capabilityVSAvoidcontrol response time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces a dual-channel communication architecture where the server acts as an intermediary for remote control while a direct short-range wireless channel provides a faster alternative. The system selectively routes control commands through the server or directly through the short-range channel based on connection status, eliminating the need to always use the slower server-mediated path.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements dynamic channel selection where the control path changes based on real-time connection status. When a short-range wireless connection is available, the system switches to direct control; when unavailable, it falls back to server-mediated control. This dynamic adaptation optimizes response time while maintaining control capability.

Inventive Principle:
Principle #15Dynamics

2Reliability

If control information is transmitted through a server, then remote control is possible, but network connectivity is required

Engineering Contradiction:
Improvecontrol capabilityVSAvoidenvironmental adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The server serves as a fallback intermediary when direct communication is not possible. The system is designed to attempt direct short-range control first, and only involves the server as an intermediary when the direct channel is unavailable, thus maintaining control capability across different environmental conditions.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes the communication parameter (control channel) based on environmental conditions. When network connectivity is unavailable, the system switches from server-mediated communication to direct short-range wireless communication, adapting to the environmental constraints while maintaining control functionality.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the electronic device maintains connection with a peripheral device, then wireless communication is established, but control by other nearby terminals is limited

Engineering Contradiction:
Improveconnection stabilityVSAvoidcontrol accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The electronic device implements multi-functional communication capability by maintaining both a stable peripheral device connection and the ability to accept control requests from other terminals. The system can simultaneously preserve the existing connection while enabling alternative control paths through the server or direct channels, making the control system universally accessible.

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

Solution Approach 2:

The patent segments the control function from the connection function. The connection to the peripheral device remains stable and dedicated, while the control acceptance is separated into a distinct function that can be selectively enabled for other terminals through channel management, allowing both connection stability and control accessibility.

Inventive Principle:
Principle #1Segmentation

4Loss of time

If a reserved channel is opened for control, then direct control is enabled, but channel management complexity increases

Engineering Contradiction:
Improvecontrol response timeVSAvoidchannel management complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by pre-establishing the reserved channel and preparing control pathways in advance. When control requests arrive, the channel is already ready, eliminating setup delays. The complexity is managed by automating the preliminary channel preparation through predefined protocols and state machine logic.

Inventive Principle:
Principle #10Preliminary action
