Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional device connection methods are used requiring user interface operations, then device pairing can be established, but user burden and operation complexity increase

Engineering Contradiction:

Improveease of device connectionVSAvoidconnection process complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The target device performs preliminary actions by emitting sonic waveforms containing identification information before the actual connection is needed. The host device receives and processes these waveforms in advance to determine device identity, so that when connection is required, the pairing process is already partially completed, eliminating the need for manual user interventions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces mechanical/manual user interface operations with acoustic wave detection and processing. Instead of requiring users to manually select devices or enter codes through physical interfaces, the system uses sonic waveforms to automatically transmit identification information, which is then processed by the host device to establish connections without mechanical user intervention.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If manual user interventions are required for device pairing, then connection security can be maintained, but connection speed decreases

Engineering Contradiction:

Improveconnection speedVSAvoidconnection security

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

Device identification and preliminary authentication occur in advance through sonic waveform exchange. The host device determines the identity of the target device by processing waveforms received before the actual connection is established, so that when the wireless data link is initialized, the security verification is already complete, enabling both fast connection and maintained security.

Inventive Principle:

Principle #10Preliminary action

3Loss of time

If device identification is performed through user interface selection, then correct device pairing can be achieved, but time consumption increases

Engineering Contradiction:

Improvedevice pairing timeVSAvoiddevice identification accuracy

Core Design Contradiction:

Loss of timeVSMeasurement precision

Solution Approach 1:

The patent substitutes manual user selection with automated acoustic identification. The target device emits sonic waveforms containing unique identification information, and the host device automatically processes these waveforms to determine device identity with high precision, eliminating the time-consuming manual selection process while maintaining or improving identification accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Sonic waveforms serve as an intermediary carrier of device identification information. Instead of direct user-to-device selection, the identification data is transmitted through acoustic waves that can be received and processed automatically, enabling fast and accurate device identification without requiring user intervention in the selection process.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The disclosure provides for, at a host computing device, a method of interacting with a target computing device. The method includes receiving one or more sonic waveforms from the target computing device at a microphone subsystem of the host computing device. The host computing device determines an identity of the target computing device via processing of the one or more sonic waveforms. In response to said identity determination, the method includes (1) initializing a wireless data link for communication between the host computing device and the target computing device, and (2) entering a mode of host-target interactivity in which the host computing device and the target computing device interact via the wireless data link.
