Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RF wireless communication technology is used, then data transfer capability is provided, but interference and congestion increase leading to reduced reliability
Solution Approach 1:
The patent replaces RF electromagnetic wave-based communication with magnetic field-based communication. The magnetic field communication system uses magnetic coupling between transmitter and receiver coils to transfer data, fundamentally substituting the RF propagation mechanism. This substitution eliminates RF interference and congestion issues while maintaining wireless data transfer capability.
2Duration of action of moving object
If wireless communication devices are used in high-density environments, then communication functionality is provided, but battery life decreases due to higher power consumption
Solution Approach 1:
The patent changes the fundamental operating parameters of wireless communication by transitioning from RF to magnetic field-based communication. Magnetic field communication operates at lower frequencies with lower power requirements compared to RF communication. The magnetic coupling mechanism enables efficient energy transfer over short distances with significantly reduced power consumption, thereby extending battery life in high-density environments.
3Reliability
If RF communication is used in congested environments, then data transfer is enabled, but audio quality deteriorates
Solution Approach 1:
The patent substitutes RF communication with magnetic field communication for audio data transfer. The magnetic coupling mechanism provides a dedicated communication channel that is immune to RF interference from other devices. This substitution ensures stable audio quality by eliminating signal congestion and interference that would otherwise degrade audio performance in high-density environments.
