Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a light detection layer is added to detect the illumination state of pixels, then message verification capability is improved, but device complexity increases

Engineering Contradiction:

Improvemessage verification capabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The light detection layer is merged with the display structure itself, integrating the verification function into the existing display architecture rather than adding separate external verification equipment. This reduces overall system complexity while maintaining verification capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The display system performs self-verification through the integrated light detection layer that monitors its own pixel illumination states. This self-service approach eliminates the need for external verification systems, reducing device complexity while improving reliability.

Inventive Principle:

Principle #25Self-service

Solution Approach 1:

A sound input transducer serves as an intermediary to capture audible messages and convert them to electrical signals for comparison. This intermediary approach enables accurate verification while keeping the comparison circuitry simple and integrated into the existing audio processing path.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system uses feedback by comparing the captured sound signal with the expected message signal and using this comparison to verify message delivery. This feedback mechanism improves verification accuracy without requiring complex additional hardware.

AI summary

An intelligent audible device is provided that is constructed to monitor for an event, such as actual or elapse time, or a sensor exceeding a threshold. Responsive to the event, a sound input transducer is activated, and an output sound signal representing an intended message is projected into the local environment by a sound output transducer. The sound input transducer captures the actual sound projected into the local environment. The captured actual sound is processed and compared to the output sound signal. In this way it may be confidently determined if the intended message was actually properly projected into the local environment.
