Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio apparatuses struggle to provide a multi-channel sound environment effectively due to variations in arrangement position and angle, requiring manual input or separate guides for posture recognition, which is inconvenient for users.
Innovation Solution
An electronic apparatus that identifies and adjusts audio data output based on the channel configuration, position, and tilt angle of connected audio devices, using processors to acquire and transmit data through communication interfaces, and sensors to track changes in arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual input is required for audio apparatus arrangement information, then measurement precision of arrangement position and angle is improved, but ease of operation deteriorates
Solution Approach 1:
The audio apparatus automatically identifies its own arrangement position and angle using internal sensors (accelerometer, gyroscope, magnetometer) without requiring user input. The system self-calibrates by detecting gravitational acceleration and magnetic field direction to determine tilt angles and spatial orientation, eliminating manual configuration steps while maintaining high measurement precision
Solution Approach 2:
The patent replaces manual mechanical input methods with automated sensor-based detection systems. Instead of requiring users to physically adjust or input arrangement data, the system uses electronic sensors (accelerometers, gyroscopes, magnetometers) to automatically detect and calculate arrangement position and angle, substituting mechanical user interaction with electronic self-detection
2Measurement precision
If separate manual or guide is provided for posture recognition, then measurement precision of arrangement angle is improved, but device complexity deteriorates
Solution Approach 1:
The patent combines multiple sensor functions (accelerometer for gravitational detection, gyroscope for rotational detection, magnetometer for magnetic field detection) into a single integrated sensor module within the audio apparatus. This merging of detection functions eliminates the need for separate manual or guide systems while maintaining high measurement precision for arrangement angle identification
Solution Approach 2:
The sensor module serves multiple functions simultaneously: it detects arrangement position, arrangement angle, tilt orientation, and spatial configuration all through a single integrated system. This multi-functionality eliminates the need for separate manual or guide mechanisms, reducing overall system complexity while maintaining comprehensive measurement capabilities
3Adaptability or versatility
If audio apparatus arrangement position and angle are not considered, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The audio apparatus automatically adapts to different arrangement environments by using its internal sensors to self-detect position and angle, then self-adjusting audio output parameters accordingly. This self-service approach provides high adaptability to various spatial configurations without requiring complex external detection systems or manual configuration
Solution Approach 2:
The system dynamically changes audio output parameters (channel assignment, speaker configuration, sound field processing) based on detected arrangement position and angle parameters. By automatically adjusting these parameters according to the detected spatial configuration, the system achieves high adaptability without requiring complex manual intervention or pre-programmed configurations
