Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electronic device performs device discovery and pairing process with external electronic devices using BLE, then communication connection between devices is established, but power consumption increases and connection management becomes complex

Engineering Contradiction:

Improveconnection establishmentVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The electronic device pre-stores connection information (device identifiers, connection parameters) of external devices in memory before actual communication needs arise. When a connection is needed, the device retrieves this pre-stored information and establishes connection quickly without performing full device discovery and pairing processes, thereby reducing power consumption while maintaining reliable connection establishment

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts only the essential connection information (device identifiers, connection parameters) from the complete device discovery and pairing process. By storing and reusing this extracted information, the system avoids repeating the entire discovery and pairing procedure, thus reducing power consumption while ensuring reliable reconnection

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If the electronic device performs device discovery and pairing process with multiple external electronic devices, then communication connections are established, but the connection management procedure becomes complex

Engineering Contradiction:

Improveconnection establishmentVSAvoidconnection management procedure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The electronic device creates copies of connection information (device identifiers, connection parameters) for multiple external devices and stores them in memory. When connection is needed, the device uses these copied information to quickly establish connections without repeating the full discovery and pairing process for each device, thereby simplifying connection management while maintaining reliable multi-device connectivity

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system performs device discovery and pairing processes in advance for multiple external devices, storing their connection information beforehand. This preliminary action allows the device to quickly reconnect to multiple external devices later without repeating the complex discovery and pairing procedures, thus simplifying connection management while ensuring reliable connections

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the electronic device performs full device discovery and pairing process each time connection is needed, then communication connection is established, but time consumption increases

Engineering Contradiction:

Improveconnection establishmentVSAvoidpairing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The electronic device performs device discovery and pairing processes in advance, storing connection information (device identifiers, connection parameters) in memory before actual communication needs arise. When connection is required, the device retrieves this pre-stored information and establishes connection quickly, dramatically reducing pairing time while ensuring reliable connection establishment

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts only the essential connection information (device identifiers, connection parameters) from the complete device discovery and pairing process. By storing and reusing this extracted information for reconnection, the system avoids repeating the time-consuming discovery and pairing procedures, thus reducing pairing time while maintaining reliable connection establishment

Inventive Principle:
