Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple microphones are used for noise cancellation and speakerphone algorithms, then audio processing capability is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the processor receives position data from the position component, compares it to optimal positions, and provides visual feedback to the user through a display. This feedback loop enables the system to automatically guide the user to the optimal position without requiring complex manual adjustment mechanisms, thus improving audio quality while managing device complexity.
Solution Approach 2:
The system performs self-diagnosis and self-correction by automatically determining the device's current position, comparing it to optimal positions, and providing guidance to the user. This self-service approach reduces the need for complex manual configuration and improves audio quality without proportionally increasing device complexity.
2Ease of operation
If visual feedback is provided to guide positioning, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent uses visual feedback through the display to show users their current position relative to the optimal position and guide them to the correct orientation. This feedback mechanism simplifies the positioning process for users while adding minimal complexity by utilizing existing display hardware.
Solution Approach 2:
The display acts as an intermediary between the position component and the user, translating complex position data into simple visual instructions. This intermediary approach improves ease of operation by making positioning intuitive while avoiding the need for complex user interfaces or controls.
3Measurement precision
If position components are added to detect orientation, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent utilizes the position component (accelerometer and/or gyroscope) to serve multiple functions: detecting device orientation, determining optimal positioning, and providing feedback for audio quality optimization. This multi-functionality improves measurement precision for positioning while minimizing the increase in device complexity by avoiding dedicated hardware for each function.
