Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional power-based wireless transmission is used, then information can be transmitted over distance, but interference and electromagnetic interference with sensitive devices occur
Solution Approach 1:
The patent changes the fundamental parameter of transmission from power-based electromagnetic waves to temperature-modulated black body radiation. By encoding information in temperature variations of a black body rather than in the amplitude or frequency of transmitted waves, the system achieves communication without traditional electromagnetic interference, as the medium (air) is not actively radiating energy but rather passively emitting thermal radiation with encoded temperature patterns.
Solution Approach 2:
The patent replaces the electromagnetic field-based transmission mechanism with a thermal radiation mechanism. Instead of using antennas to transmit electromagnetic waves that carry information through power modulation, the system uses a black body whose temperature is modulated to encode information, and this thermal radiation is detected by a radiation detector, substituting electromagnetic transmission with thermal radiation detection.
2Loss of information
If power-based transmissions are used, then communication can occur, but data privacy concerns and safety risks arise
Solution Approach 1:
The patent fundamentally changes the transmission parameter from power to temperature modulation of black body radiation. This approach inherently addresses privacy and safety concerns because the system does not transmit detectable electromagnetic signals that could be intercepted or cause harm; instead, it uses passive thermal radiation that is indistinguishable from ambient thermal noise, making eavesdropping impossible and eliminating electromagnetic safety risks.
3Loss of information
If traditional wireless communication methods are used, then information transmission is achieved, but bandwidth is limited
Solution Approach 1:
The patent changes from modulating electromagnetic wave parameters (frequency, amplitude, phase) to modulating the temperature of a black body. This temperature modulation creates variations in black body radiation across a broad spectral range, effectively utilizing the entire thermal radiation spectrum rather than a narrow communication band, thereby dramatically increasing available bandwidth and information transmission capacity.
