Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expert knowledge is used to determine optimal placement of audio equipment, then the accuracy of achieving target sound pressure distribution is improved, but the complexity and difficulty of operation increases
Solution Approach 1:
The patent introduces a computer as an intermediary device that automatically calculates and determines the optimal placement positions of audio equipment. The computer executes predetermined calculation processes to generate placement information, serving as a mediator between the user and the complex acoustic optimization problem, thereby eliminating the need for user expertise while maintaining high accuracy
Solution Approach 2:
The system enables self-service by allowing the computer to autonomously perform the entire placement determination process without human intervention. The computer automatically receives acoustic space information, calculates optimal positions based on target sound pressure distribution, and outputs placement recommendations, making the system self-sufficient and removing the barrier of requiring expert knowledge
2Ease of operation
If automatic calculation of equipment placement is implemented, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-storing multiple types of acoustic space information (room dimensions, obstacle positions, reflection characteristics) and predetermined calculation algorithms in the computer before actual use. This preparation phase creates a ready-to-use system that automatically processes user inputs without requiring complex real-time computations, thereby simplifying the operational interface while maintaining sophisticated calculation capabilities
Solution Approach 2:
The system segments the complex calculation process into distinct functional modules: receiving acoustic space information, selecting appropriate calculation methods based on space type, executing placement optimization algorithms, and outputting results. This modular segmentation allows the computer to handle complexity internally through structured processing while presenting a simple unified interface to the user
