Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a speaker assembly outputs sound in a fixed direction, then the acoustic characteristics are optimized for that direction, but the sound quality becomes dependent on the listener's position
Solution Approach 1:
The patent introduces a light-transmitting plate with specific geometric features (convex portions and concave portions) that redirect sound waves from the vertical direction to horizontal directions. This dimensional transformation of sound propagation enables omnidirectional sound distribution while preserving acoustic characteristics optimized for vertical output.
Solution Approach 2:
The light-transmitting plate serves as an intermediary component between the speaker and the listener. It receives sound waves from the speaker and redirects them to multiple directions, acting as a mediator that maintains acoustic quality while providing position-independent sound delivery.
2Illumination intensity
If a light-transmitting plate is placed close to the speaker, then lighting effects are enhanced, but acoustic characteristics deteriorate
Solution Approach 1:
The light-transmitting plate is designed with non-uniform thickness, featuring convex portions and concave portions at different locations. This local variation in thickness creates different acoustic paths and light transmission characteristics in different regions, allowing optimization of both acoustic properties and lighting effects simultaneously.
Solution Approach 2:
The varying thickness of the light-transmitting plate introduces a third dimension (vertical thickness variation) to the acoustic and optical path lengths. This dimensional variation allows independent optimization of acoustic characteristics through path length adjustment while maintaining effective light transmission for lighting effects.
3Ease of manufacture
If the light-transmitting plate has uniform thickness, then manufacturing is simplified, but both acoustic and lighting effects are suboptimal
Solution Approach 1:
The light-transmitting plate incorporates local variations in thickness with convex portions and concave portions strategically positioned to optimize specific acoustic paths and light transmission angles. This localized quality variation enhances both acoustic characteristics and lighting effects while remaining manufacturable.
Solution Approach 2:
The light-transmitting plate features curved surfaces (convex and concave portions) that redirect sound waves and light in specific directions. These curved geometries provide sophisticated acoustic and optical performance while maintaining compatibility with standard manufacturing processes.
