Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If Bluetooth data processing is performed on the main processing unit (AP), then Bluetooth communication functionality is ensured, but power consumption increases due to the main processing unit being constantly in working state

Engineering Contradiction:

ImproveBluetooth communication functionalityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent segments Bluetooth data processing tasks by deploying specific Bluetooth services on an auxiliary processing unit (separate from the main application processor). This division allows the main processing unit to handle other tasks while the auxiliary unit handles Bluetooth data processing, reducing the main unit's working time and power consumption while maintaining full Bluetooth functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an auxiliary processing unit as an intermediary between the Bluetooth chip and the main application processor. This intermediary handles Bluetooth data processing tasks, preventing the main processor from being constantly activated and thereby reducing overall system power consumption while ensuring reliable Bluetooth communication.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the main processing unit processes all Bluetooth data, then comprehensive Bluetooth service support is achieved, but working time of the main processing unit increases

Engineering Contradiction:

ImproveBluetooth service supportVSAvoidworking time of main processing unit

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of moving object

Solution Approach 1:

The patent segments Bluetooth service processing by deploying specific Bluetooth services on the auxiliary processing unit. This allows the main processing unit to focus on other tasks while the auxiliary unit handles Bluetooth data processing, thereby reducing the main unit's working time without compromising comprehensive Bluetooth service support.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The auxiliary processing unit independently handles Bluetooth data processing tasks that were previously requiring main processing unit involvement. This self-service capability of the auxiliary unit reduces the workload and working time of the main processing unit while maintaining full Bluetooth service functionality.

Inventive Principle:

Principle #25Self-service

3Use of energy by moving object

If Bluetooth services are deployed on the auxiliary processing unit, then power consumption is reduced, but system complexity increases due to multi-unit coordination

Engineering Contradiction:

Improvepower consumptionVSAvoidsystem complexity

Core Design Contradiction:

Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The auxiliary processing unit acts as an intermediary that simplifies the overall system architecture by handling Bluetooth data processing independently. This reduces the need for constant main processor involvement, and while it adds a component, it actually simplifies the main processor's workload and can be managed through standardized interfaces.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts Bluetooth data processing functionality from the main processing unit and places it on an auxiliary processing unit. This extraction reduces the complexity of the main processing unit's task schedule and power management, as the auxiliary unit independently manages Bluetooth processing according to preset conditions.

Inventive Principle:

Principle #2Taking out (Extraction)
