Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional microphones are used for sound collection, then sound information can be obtained, but the device complexity increases and the frequency range coverage is limited
Solution Approach 1:
The patent replaces the traditional mechanical microphone system with an electromagnetic wave-based detection system. The reflective module converts sound vibrations into electromagnetic wave reflections, which are then detected by the receiving end. This substitution eliminates the need for complex mechanical components and transducers, thereby reducing device complexity while expanding frequency range coverage to include ultrasonic and infrasonic frequencies beyond human hearing range.
Solution Approach 2:
The patent introduces an electromagnetic wave reflective module as an intermediary between the sound source and the receiving end. This reflective module acts as a mediator that converts acoustic vibrations into electromagnetic wave reflections, enabling the receiving end to detect sound information wirelessly without direct contact with the sound source. This intermediary approach simplifies the overall system architecture while enhancing adaptability to various frequency ranges.
2Loss of information
If microphones are deployed at multiple locations for sound collection, then comprehensive sound information can be obtained, but the device complexity and quantity of components increase
Solution Approach 1:
The patent creates a multi-functional system where a single receiving end can detect sound information from multiple locations simultaneously. The reflective modules at different locations all reflect electromagnetic waves back to the same receiving end, which then processes and distinguishes the reflected signals to obtain sound information from multiple positions. This universal approach eliminates the need for separate receiving devices at each location, reducing component quantity while maintaining sound information completeness.
Solution Approach 2:
The patent merges multiple sound detection functions into a single receiving end device. Instead of having separate microphones and receiving devices at each monitoring location, the system combines all detection functions into one centralized receiving end that processes reflected electromagnetic waves from multiple reflective modules. This merging approach reduces the total number of components while ensuring comprehensive sound information collection from all locations.
3Adaptability or versatility
If traditional sound detection methods are used in environments where active components are not suitable, then sound collection is limited, but the adaptability to harsh environments is reduced
Solution Approach 1:
The patent replaces mechanical microphones with passive electromagnetic wave reflective modules that have no active components. These reflective modules can be deployed in harsh environments such as high temperature, high humidity, or corrosive conditions where electronic microphones would fail. The modules passively reflect electromagnetic waves according to sound vibrations without requiring power or active electronics, thereby maintaining sound information retrieval capability while significantly improving environmental adaptability.
Solution Approach 2:
The patent employs simple, passive reflective modules that can be easily manufactured and deployed in harsh environments where traditional microphones cannot survive. These modules are designed to be robust and environment-resistant, sacrificing the need for complex protection mechanisms while maintaining functionality. The simplicity and robustness of these passive modules make them ideal for disposable or temporary deployment in extreme conditions.
