1Reliability

If conventional localization and mapping methods are used in unknown non-line-of-sight environments, then imaging and localization can be performed, but multipath effects and attenuation occur causing degraded performance

Engineering Contradiction:

Improvelocalization and mapping performanceVSAvoidmultipath effects and attenuation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent converts harmful multipath effects into useful information by designing a system that intentionally transmits engineered electromagnetic interference through the same multipath channels. By transmitting known probe signals and receiving their scattered versions, the system uses the multipath effects themselves as the measurement mechanism, transforming the harmful interference into the basis for localization and imaging.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The system changes the parameters of electromagnetic wave transmission by using wideband probe signals with specific temporal and spectral characteristics. The trigger voltage signal synchronizes transmission across multiple transmitters, and the conversion stage processes received signals through correlation operations, transforming the raw scattered waves into localized information through parameter-based signal processing.

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The system employs periodic transmission of probe signals synchronized by a trigger voltage source. Multiple transmitters send periodic electromagnetic waves that scatter off the target, and receivers periodically sample the returned signals. This periodic action enables real-time monitoring and fast response while allowing signal processing to accumulate information over multiple cycles, reducing instantaneous bandwidth demands.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system performs preliminary signal processing by correlating received scattered waves with the known transmitted probe signals before full data acquisition. The conversion stage pre-processes signals by comparing received patterns against expected patterns, extracting localization information early in the signal chain before requiring full-bandwidth storage or transmission of raw data.
