Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wired communication systems are used, then communication reliability is maintained, but mobility is restricted and visual signature is increased
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless electromagnetic field-based communication system. The mouthpiece component and relay component communicate via wireless signals, eliminating physical wires and improving mobility while maintaining communication reliability through the wireless link.
Solution Approach 2:
The patent extracts and removes the wire component from the communication system. By taking out the physical connection element, the system achieves wireless operation, improving mobility and reducing visual signature while maintaining communication functionality through alternative wireless transmission methods.
2Adaptability or versatility
If traditional communication systems are used, then communication functionality is provided, but visual signature is increased due to visible components
Solution Approach 1:
The patent segments the communication system into separate components: a mouthpiece component that can be placed in the mouth and a relay component that can be positioned elsewhere on the body. This segmentation allows each component to be minimized and hidden, reducing the visual signature while maintaining full communication functionality through their wireless connection.
Solution Approach 2:
The patent transitions the communication system from an external visible configuration to an internal/hidden configuration by placing the mouthpiece in the oral cavity and positioning the relay component on the body. This dimensional change moves components from external visibility to internal concealment, reducing visual signature while preserving functionality.
3Loss of information
If standard microphones are used in loud environments, then speech capture is attempted, but signal-to-noise ratio deteriorates
Solution Approach 1:
The patent introduces the user's own body (teeth and skull) as an intermediary medium for signal transmission. The bone conduction transducer converts speech vibrations into mechanical vibrations that travel through the skull to the inner ear, using the body as a transmission medium that isolates the signal from external noise, thereby improving signal-to-noise ratio in loud environments.
4Reliability
If wired communication gear is worn, then communication capability is provided, but movement restriction and entanglement risk increase
Solution Approach 1:
The patent replaces the mechanical wire-based connection system with an electromagnetic field-based wireless system. This substitution eliminates the physical constraints of wires, allowing free movement without entanglement risk while maintaining communication capability through wireless transmission between components.
