Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If bass speaker and treble speaker are assembled into one electronic device, then space utilization is improved, but speaker sizes are restricted which affects full-frequency effects and sound quality
Solution Approach 1:
The vibration system is divided into three independent vibration units (bass, midrange, and treble), each capable of generating specific frequency ranges. This segmentation allows each unit to be optimized for its frequency band while being integrated into a compact structure, resolving the contradiction between space utilization and sound quality.
Solution Approach 2:
The midrange vibration unit and treble vibration unit are arranged on one side of the magnetic circuit system with the midrange unit surrounding the treble unit, creating a nested configuration. The bass vibration unit is positioned on the opposite side. This nesting approach maximizes space utilization while maintaining adequate size for each vibration unit to deliver quality sound.
2Device complexity
If bass speaker and treble speaker are assembled into one electronic device, then device integration is improved, but full-frequency effects are reduced due to size restrictions
Solution Approach 1:
The system segments the frequency response into three distinct bands handled by separate vibration units, allowing each unit to be sized appropriately for its frequency range. This segmentation enables full-frequency effects to be maintained despite the integrated compact design.
Solution Approach 2:
The patent utilizes three-dimensional space arrangement by positioning the midrange and treble units on one side of the magnetic circuit system while placing the bass unit on the opposite side. This spatial arrangement in multiple dimensions allows for better frequency separation and full-frequency effects within a compact integrated device.
3Reliability
If bass unit is designed for low-frequency performance, then bass performance is improved, but midrange performance cannot be fully utilized
Solution Approach 1:
The vibration system is segmented into three independent units, each dedicated to a specific frequency range. The bass vibration unit is optimized for low-frequency performance, while the midrange and treble units are separately designed to handle their respective frequency bands, allowing all three performance aspects to be fully utilized simultaneously.
Solution Approach 2:
Each vibration unit is designed with local quality optimization for its specific frequency range. The bass unit has characteristics optimized for low-frequency response, while the midrange and treble units have characteristics optimized for their respective higher frequency ranges, enabling the system to achieve excellent performance across all frequency bands.
