Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical installation of speakers and materials is performed for acoustic simulation, then measurement precision is improved, but loss of substance increases and productivity decreases
Solution Approach 1:
The patent creates a virtual copy of the building space using building information modeling (BIM) technology, allowing acoustic simulation to be performed on the digital replica instead of requiring physical installation of speakers and materials in the actual building. This virtual copying enables repeated simulations without consuming additional physical materials.
Solution Approach 2:
The patent replaces the physical mechanical system of installing speakers and acoustic materials in the building with a computational acoustic simulation system that calculates sound propagation, reflection, and absorption using the virtual building model, thereby eliminating the need for physical material installation during the simulation phase.
2Measurement precision
If physical installation of speakers and materials is performed for acoustic simulation, then measurement precision is improved, but productivity decreases
Solution Approach 1:
The patent performs acoustic simulations in the virtual building model before actual construction or renovation takes place, allowing multiple design iterations and optimizations to be completed in advance. This preliminary simulation enables the selection of the best acoustic design方案 without the time-consuming process of physical installation and measurement for each iteration.
Solution Approach 2:
By using a virtual copy of the building for simulation, the system enables rapid iteration and testing of multiple acoustic designs without the productivity loss associated with repeated physical installations, while still achieving accurate measurement results through the virtual environment.
3Reliability
If physical installation of speakers is performed for acoustic simulation, then reliability is improved, but loss of time increases and productivity decreases
Solution Approach 1:
The patent performs acoustic simulations before actual speaker installation, allowing the optimal speaker positions and configurations to be determined in advance through virtual testing. This preliminary action ensures design reliability is established beforehand, eliminating the need for time-consuming trial-and-error installations.
Solution Approach 2:
The patent replaces time-consuming physical speaker installations with computational acoustic simulations that calculate sound field distributions and speaker performance metrics virtually, achieving the same reliability assessment without the time loss associated with physical setup and measurement.
