Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional absorptive methods are used in loudspeaker enclosures, then reflected energy is diminished, but the reflected waveform becomes inverted and reduced in amplitude
Solution Approach 1:
The patent employs curved diffusers with specific geometric profiles (hyperbolic, parabolic, or spherical surfaces) to reflect acoustic energy. These curved surfaces redirect sound waves through multiple reflections while maintaining waveform integrity, eliminating the inversion problem caused by flat absorptive surfaces while still reducing reflected energy amplitude.
Solution Approach 2:
The invention transitions from two-dimensional flat absorptive surfaces to three-dimensional curved diffuser structures. By adding spatial dimensionality with varying depths and curved geometries, the system achieves multiple reflection paths that preserve waveform phase while distributing energy across different spatial dimensions, thereby reducing overall reflected energy without inversion.
2Loss of energy
If multiple reflections are implemented through absorptive media, then energy absorption is enhanced, but the device complexity increases
Solution Approach 1:
The diffuser surface is divided into multiple discrete elements or wells of varying depths and geometries. Each segment independently creates reflection paths, and collectively they achieve multiple reflections throughout the structure. This segmentation allows complex absorption behavior to be built from simpler modular components, managing overall device complexity.
Solution Approach 2:
The patent implements nested reflection paths where sound waves traverse through progressively deeper layers or wells within the diffuser structure. Each nested level provides additional reflection opportunities, effectively multiplying the absorption passes without requiring proportionally increased external dimensions, thus controlling device complexity while enhancing energy absorption.
