Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automatic connection is enabled based on proximity, then connection convenience is improved, but connection accuracy deteriorates

Engineering Contradiction:
Improveconnection convenienceVSAvoidconnection accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent applies parameter changes by dynamically adjusting connection configuration parameters (such as signal strength thresholds, connection priority levels, and disconnection distances) based on device attributes and user behavior patterns. This allows the system to maintain automatic connection convenience while improving accuracy by adapting parameters to specific scenarios and devices.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system implements feedback mechanisms by continuously monitoring connection status, signal quality, and user interactions. Based on this feedback, the system automatically adjusts connection configurations and provides users with connection suggestions, thereby improving connection accuracy while maintaining the convenience of automatic connection.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If connection configuration is customized for each device, then connection precision is improved, but system complexity increases

Engineering Contradiction:
Improveconnection precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing connection management into device-specific configuration modules. Each terminal device has its own connection configuration profile stored in the database, allowing customized connection parameters for different devices while maintaining a standardized system architecture. This reduces perceived complexity by organizing complexity in a structured, manageable way.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements self-service by automatically generating and managing connection configuration profiles for different devices. The system autonomously stores device attributes, determines appropriate connection parameters, and applies configurations without requiring manual user setup for each device, thereby achieving high connection precision without increasing user-facing complexity.

Inventive Principle:
Principle #25Self-service

AI summary

A control method includes: obtaining target reference information, the target reference information being used to at least characterize a signal parameter of a target communication signal between an electronic device and a terminal device; and controlling a communication connection state with the terminal device based on connection configuration information corresponding to the terminal device and the target reference information, the connection configuration information being information of the communication signal required to configure the terminal device to establish or disconnect the target communication connection with the electronic device, and the connection configuration information configured for different terminal devices being same or different.
