Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If acoustic device arrangement is determined using traditional simulation methods, then arrangement optimization is achieved, but technical knowledge and complexity are required
Solution Approach 1:
The patent uses pre-calculated arrangement distribution data stored in a database as a template or copy of optimal arrangements. Instead of performing complex real-time simulations, the system retrieves and displays pre-computed arrangement distributions that have been calculated in advance for various acoustic spaces and noise source positions, thereby providing optimization results without requiring users to have acoustic expertise
Solution Approach 2:
The system performs arrangement distribution calculations in advance and stores them in a database before actual use. When a user needs arrangement optimization, the system retrieves pre-computed data based on the acoustic space and noise source position, eliminating the need for users to perform complex real-time simulations and reducing the technical knowledge barrier
2Measurement precision
If detailed acoustic simulation is performed, then arrangement accuracy is improved, but calculation time and complexity increase
Solution Approach 1:
The system pre-calculates arrangement distributions for various acoustic spaces and noise source positions, storing the results in a database. When a user inputs their specific acoustic space and noise source position, the system quickly retrieves the corresponding pre-computed arrangement distribution, providing accurate results without requiring time-consuming real-time simulations
3Reliability
If noise sources are considered in arrangement calculation, then voice collection quality is improved, but system complexity increases
Solution Approach 1:
The system stores pre-calculated arrangement distribution data in a database that incorporates the effects of noise sources on voice collection quality. This pre-computed data acts as a template that already accounts for noise source considerations, allowing the system to provide optimized arrangements that improve voice collection quality without requiring users to understand or configure complex noise source models

AI summary
A method of supporting arrangement design of acoustic devices receives an acoustic space and a position of a sound source in the acoustic space and a position of a noise source in the acoustic space, calculates, in the received acoustic space, arrangement distribution of the acoustic devices corresponding to the position of the sound source and the position of the noise source that have been received, and displays the calculated arrangement distribution on a display.
