Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If wired connections are used for controlling devices, then control stability is improved, but testing accuracy deteriorates due to skewing effects

Engineering Contradiction:

Improvecontrol stabilityVSAvoidtesting accuracy

Core Design Contradiction:

Stability of the object's compositionVSMeasurement precision

Solution Approach 1:

The patent replaces the mechanical wired connection system with a wireless communication system using Bluetooth protocol. The host controller interface commands are transmitted wirelessly from the remote device to the device under test, eliminating the physical cable that causes skewing effects during testing while maintaining reliable command transmission and control stability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If wireless control is implemented, then testing accuracy is improved by eliminating wired connection skewing, but control reliability may worsen due to wireless interference

Engineering Contradiction:

Improvetesting accuracyVSAvoidcontrol reliability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent introduces a dedicated Bluetooth host controller interface as an intermediary communication channel between the remote device and the device under test. This specialized wireless interface provides reliable command transmission with error handling and protocol-based data integrity, ensuring control reliability while maintaining the accuracy benefits of wireless testing.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If HCI commands are processed wirelessly, then ease of operation is improved, but device complexity increases due to additional wireless control modules

Engineering Contradiction:

Improveease of operationVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by enabling the device to operate in both traditional wired host controller interface mode and wireless HCI remote control mode. The same device can accept commands through wired connections for standard operation and through wireless Bluetooth connections for remote testing and operation, eliminating the need for separate systems and reducing overall complexity despite adding wireless capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)
