Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional static audio output methods are used, then device complexity is reduced, but adaptability to user pose and ambient audio changes deteriorates

Engineering Contradiction:

Improveadaptability to user pose and ambient audioVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic audio output by continuously monitoring user pose through sensors (accelerometers, gyroscopes, magnetometers) and ambient audio through microphones, then adaptively adjusting audio content in real-time based on detected changes in user orientation, movement, or environmental conditions

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs feedback mechanisms where audio output is continuously adjusted based on feedback from pose sensors detecting user orientation and movement, and from microphones detecting ambient audio levels, creating a closed-loop adaptive audio delivery system

Inventive Principle:

Principle #23Feedback

2Ease of operation

If adaptive audio adjustments are made in real-time, then user interaction with environment is enhanced, but energy consumption increases

Engineering Contradiction:

Improveuser interaction with environmentVSAvoidbattery power consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic sampling of sensor data and ambient audio rather than continuous processing, adjusting audio output at discrete intervals based on detected changes, thereby reducing computational load and power consumption while maintaining adaptive functionality

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system automatically detects user pose changes and ambient audio conditions without requiring manual user input or control, self-adjusting audio output based on sensor data and environmental context, eliminating the need for user-initiated adjustments

Inventive Principle:

Principle #25Self-service

3Reliability

If static audio output is provided, then power consumption is reduced, but ability to understand spoken communication deteriorates

Engineering Contradiction:

Improveability to understand spoken communicationVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The system uses feedback from ambient audio microphones to detect when external speech is present, automatically adjusting audio output levels or spatial positioning to facilitate understanding of spoken communication without requiring user intervention

Inventive Principle:

Principle #23Feedback

AI summary

An electronic device includes one or more pose sensors for detecting a pose of a user of the electronic device relative to a first physical environment and is in communication with one or more audio output devices. While a first pose of the user meets first presentation criteria, the electronic device provides audio content at a first simulated spatial location relative to the user. The electronic device detects a change in the pose of the user from the first pose to a second pose. In response to detecting the change in the pose of the user, and in accordance with a determination that the second pose of the user does not meet the first presentation criteria, the electronic device provides audio content at a second simulated spatial location relative to the user that is different from the first simulated spatial location.
