Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user plays a musical instrument in a specific physical location, then the acoustic characteristics are determined by the physical environment, but the user cannot experience playing the same instrument in different environments without physically relocating
Solution Approach 1:
The patent creates virtual copies of musical instruments with their acoustic characteristics captured through image information and acoustic information. These digital copies allow users to experience playing instruments in different environments without physical relocation, resolving the contradiction between environmental adaptability and system complexity by using information-based replication rather than physical replication
Solution Approach 2:
The patent introduces an information processing system as an intermediary between the user and the physical instrument. This mediator captures, processes, and reproduces acoustic characteristics through digital information, enabling users to experience different playing environments without direct physical presence, thus achieving environmental adaptability while managing system complexity through software-based solutions
2Measurement precision
If acoustic information is captured to represent environmental characteristics, then the fidelity of environmental representation improves, but the amount of data to be processed and transmitted increases
Solution Approach 1:
The patent extracts essential acoustic characteristics from complex environmental acoustic information. By identifying and separating the key parameters that define acoustic environments (such as reverberation time, frequency response, and spatial characteristics), the system achieves high measurement precision while reducing data volume to only the most critical acoustic parameters
Solution Approach 2:
The patent transforms complex acoustic information into simplified parameter representations. By converting detailed acoustic measurements into standardized parameters that capture the essential characteristics of different playing environments, the system maintains measurement precision while significantly reducing the quantity of data that needs to be stored and transmitted
3Speed
If the system renders images and generates performance sounds in real-time based on user input, then the responsiveness to user performance improves, but the computational load increases
Solution Approach 1:
The patent performs preliminary processing of acoustic information and pre-calculates rendering parameters before actual performance occurs. By preparing image information, acoustic models, and environmental characteristics in advance, the system can respond to user performance with minimal real-time computation, achieving high response speed while managing computational energy consumption through advance preparation
Solution Approach 2:
The patent implements dynamic adjustment of rendering quality and computational intensity based on performance context. By varying the level of detail in image rendering and sound generation according to the specific performance situation, the system optimizes the balance between response speed and computational energy consumption, using higher fidelity only when necessary
