Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hybrid connection technologies (bond wires, solder locations) are used to connect semiconductor chip to circuit card, then electrical connection is achieved, but parasitic elements disturb the transfer behavior and cause signal attenuation at frequencies above 100 GHz

Engineering Contradiction:
Improvesignal transfer qualityVSAvoidparasitic elements and signal attenuation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines the semiconductor chip with the support structure (circuit card) into a monolithic integration where the chip is directly mounted on the support without external conductive traces, soldered connections, or bond wires. This merging eliminates the parasitic elements introduced by hybrid connection technologies and enables reliable signal transfer at millimeter wave frequencies above 100 GHz

Inventive Principle:
Principle #5Merging (Combining)

2Area of stationary object

If the primary radiator emits radar signals in the complete half space, then signal coverage is maximized, but signal power is dispersed and bunching angle cannot be controlled

Engineering Contradiction:
Improvesignal coverage areaVSAvoidfill level detection accuracy
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

Solution Approach 1:

The patent introduces a vertical dimension by creating a step structure on the support surface. The semiconductor chip is mounted on this step, which has a height corresponding to a quarter-wavelength or whole-number multiple thereof. This dimensional change causes the radar signals to be emitted and received perpendicular to the support surface, concentrating the beam in a specific direction rather than dispersing it across the entire half space, thereby achieving controlled bunching angle and improved measurement precision

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Measurement precision

If a large aperture lens or parabolic reflector is used to bunch the radar signal, then bunching angle is controlled, but total reflection losses increase significantly

Engineering Contradiction:
Improvesignal bunching controlVSAvoidtotal reflection losses
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

The patent changes the geometric parameter of the support structure by introducing a step with a specific height (quarter-wavelength or whole-number multiple). This parameter change enables the radar signals to be automatically bunched perpendicular to the support surface without requiring large aperture lenses or parabolic reflectors, thereby controlling the bunching angle while minimizing total reflection losses and improving power efficiency
