Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional pairing mechanisms are used, then device pairing can be achieved, but the pairing process becomes complex and time-consuming requiring technical setup procedures

Engineering Contradiction:

Improvepairing operationVSAvoidpairing time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The device automatically performs pairing operations by detecting sound signatures from the remote controller and extracting authentication information, eliminating the need for users to manually initiate pairing procedures or enter technical setup modes

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The device continuously monitors and analyzes sound signatures in the environment before pairing is requested, so that when a remote controller is brought into range, the pairing process can be immediately executed without delay for setup procedures

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If remote controllers are used in environments with multiple devices, then device control is possible, but accidental control of the wrong device occurs

Engineering Contradiction:

Improvedevice control capabilityVSAvoidcontrol accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The device uses sound signature analysis as a feedback mechanism to verify the identity of the remote controller and confirm proper pairing before accepting control commands, ensuring that only the intended device responds to remote control inputs

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The sound signature acts as an intermediary authentication layer between the remote controller and the device, providing a reliable method to distinguish between multiple devices in the environment without requiring direct user intervention

Inventive Principle:

Principle #24Intermediary (Mediator)
