Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rays are emitted based on predetermined points in VR to generate sound effects, then sound effects can be generated at specific locations, but sound effects are limited only to predetermined points and cannot be generated at any desired location
Solution Approach 1:
The patent replaces the traditional mechanical/ray-based sound generation system with a physics-based simulation system. Instead of emitting rays from predetermined points, the system simulates physical forces (pressure, temperature, density changes) in the virtual atmosphere to generate sound effects at any location. This substitution enables continuous spatial sound generation while maintaining manageable system complexity through physics-based modeling.
Solution Approach 2:
The patent changes the fundamental parameters of sound generation from discrete point-based ray emission to continuous physical field simulation. By simulating physical parameters (pressure, temperature, density) in the virtual atmosphere, the system can generate sound effects at any continuous location within the VR environment, achieving full spatial flexibility without being constrained to predetermined points.
2Ease of manufacture
If traditional ray emission methods are used for sound effects, then implementation is straightforward at predetermined points, but the ability to express all sounds in real space is limited
Solution Approach 1:
The patent creates a universal sound generation system based on physical force simulation that can handle diverse sound effects (explosions, weather, ambient sounds, object interactions) through a single unified approach. Instead of implementing separate ray emission methods for different sound types at predetermined points, the physical simulation system can generate any sound effect anywhere in the virtual space by applying appropriate physical forces to the virtual atmosphere.
Solution Approach 2:
The patent replaces the limited ray emission mechanism with a comprehensive physics-based simulation system that can express all sounds in real space. By simulating physical forces and their effects on the virtual atmosphere, the system achieves complete sound expression capability while maintaining ease of implementation through standardized physics-based processing.
