Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional microphones are used for sound information collection, then the device structure is simple and easy to manufacture, but the applicability is limited in environments where active components are not suitable and cannot collect sound information at multiple locations simultaneously
Solution Approach 1:
The patent replaces traditional mechanical microphones with an electromagnetic wave-based detection system. Electromagnetic wave reflective arrays are used to detect sound-induced vibrations without requiring active electronic components at the sound collection location, enabling operation in environments where active components are unsuitable.
Solution Approach 2:
The electromagnetic wave reflective array system serves multiple functions: it can collect sound information at multiple locations simultaneously, determine vibration source direction, and restore sound information, making it universally applicable to various sound detection scenarios including those where traditional microphones fail.
2Productivity
If traditional microphones are used for sound information collection, then the device structure is simple, but the efficiency is low when collecting sound information at multiple locations
Solution Approach 1:
The patent merges multiple sound collection functions into a single electromagnetic wave reflective array system. The array can simultaneously detect vibrations at multiple locations and process the information centrally, achieving efficient multi-location sound information collection without requiring multiple separate microphone systems.
Solution Approach 2:
The patent introduces electromagnetic waves as an intermediary to transfer sound information from multiple locations to a single receiving end. The electromagnetic wave reflective arrays at different locations reflect electromagnetic waves that carry vibration information, which are then collected and processed by one central receiver,提高效率 without requiring multiple active recording devices.
3Adaptability or versatility
If electromagnetic wave reflective arrays are used to collect sound information at multiple locations, then the adaptability and collection efficiency are improved, but the device complexity increases
Solution Approach 1:
The patent divides the electromagnetic wave reflective array into multiple reflective units with different characteristics. Each unit can be independently configured for specific locations, allowing the system to adapt to different sound collection requirements while maintaining modular simplicity that reduces overall system complexity.
Solution Approach 2:
The patent assigns different electromagnetic wave reflective characteristics to different reflective units based on their specific locations and detection requirements. This local optimization allows each unit to be tailored for its specific function while the overall system maintains a relatively simple structure through standardized design principles.
