Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If communications are enabled within a defined space, then communication capability is improved, but noise level control deteriorates

Engineering Contradiction:

Improvecommunication capabilityVSAvoidnoise level

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system continuously monitors sound pressure levels via sensors and provides real-time feedback to the communication device. When noise thresholds are exceeded, the system automatically triggers remedial actions such as warnings or communication termination, creating a closed-loop control system that maintains noise compliance while enabling communications

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The noise threshold is not fixed but dynamically adjusted based on ambient sound conditions. The system determines an adapted threshold by combining a predetermined threshold with the measured second sound pressure level of ambient sound, allowing the communication limits to adapt to varying environmental conditions

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If strict noise thresholds are enforced, then tranquility is improved, but communication flexibility deteriorates

Engineering Contradiction:

ImprovetranquilityVSAvoidcommunication flexibility

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the effective noise threshold by combining a predetermined threshold with measured ambient sound levels. This allows the communication device to operate with higher effective limits when ambient noise is high, while maintaining strict control when ambient noise is low, thus preserving both tranquility and communication flexibility

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of communication based on measured sound pressure levels. By adjusting the adapted threshold parameter dynamically and triggering different remedial actions based on threshold violations, the system maintains tranquility while allowing flexible communication under varying conditions

Inventive Principle:

Principle #35Parameter changes

3Measurement precision

If ambient sound is used to determine adapted threshold, then noise control precision is improved, but system complexity deteriorates

Engineering Contradiction:

Improvenoise control precisionVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The sound pressure level sensor serves multiple functions: it measures both the first sound pressure level (sound from user) and the second sound pressure level (ambient sound). This multi-functionality allows the system to determine adapted thresholds with high precision without adding separate sensing systems, thereby managing complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A system for facilitating compliance with voice call restrictions for a defined space includes a communication device and a sound pressure level sensor. The communication device includes a processor and is configured to access a communications network associated with the defined space to transmit and receive audio data. The sound pressure level sensor is configured to detect sound levels received by the communication device. The processor is configured to: determine a first sound pressure level associated with sound emanating from a user of the communication device based on input from the sound pressure level sensor; determine a second sound pressure level associated with ambient sound within the defined space; determine an adapted threshold value based on a predetermined threshold value and the second sound pressure level; compare the first sound pressure level to the adapted threshold value; and in response to determining that the first sound pressure level exceeds the adapted threshold value, executing a remedial action on the communication device, wherein the remedial action comprises temporarily disabling the communication device and terminating transmission and reception for the audio data.
