Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical measurements and manual adjustments are performed in an anechoic chamber, then measurement precision is improved, but time consumption increases significantly
Solution Approach 1:
The patent creates a virtual copy of the anechoic chamber environment through software simulation. The virtual anechoic chamber replicates the acoustic measurement capabilities of the physical chamber without requiring physical presence, allowing multiple measurements to be performed simultaneously and rapidly without the time-consuming setup and teardown required in physical chambers.
Solution Approach 2:
The patent replaces the mechanical physical measurement system with a software-based virtual measurement system. Instead of physically moving equipment in and out of an anechoic chamber, the system uses computational acoustic models and software simulations to perform measurements, eliminating the time-consuming mechanical operations while maintaining measurement precision.
2Manufacturing precision
If repeated physical adjustments and firmware upgrades are performed, then sound quality is improved, but operational complexity increases
Solution Approach 1:
The patent implements a self-service adjustment system where the loudspeaker performs its own tuning and optimization. The system automatically analyzes acoustic measurements and adjusts its own parameters through software control, eliminating the need for manual physical adjustments and firmware upgrades by external technicians, thereby reducing operational complexity while maintaining sound quality improvements.
Solution Approach 2:
The patent makes the loudspeaker's acoustic characteristics dynamically adjustable through software control. Instead of requiring static physical adjustments and firmware upgrades, the system allows real-time dynamic modification of acoustic parameters, enabling continuous optimization without increasing operational complexity.
3Manufacturing precision
If multiple firmware upgrades are performed during development, then sound quality is improved, but productivity decreases
Solution Approach 1:
The patent replaces firmware-based adjustments with software-based control mechanisms. This substitution allows for rapid parameter changes without requiring actual firmware flashing operations, significantly accelerating the development process while maintaining the ability to achieve sound quality improvements through software tuning rather than repeated firmware upgrades.
Solution Approach 2:
The patent performs preliminary acoustic modeling and parameter optimization during the design phase using virtual simulations. This preliminary action allows developers to identify optimal settings before physical prototyping, reducing the need for repeated firmware upgrades and speed up the overall development process by pre-determining effective configurations.
