Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional circuit techniques struggle to process sub-millimeter signals due to their short wavelengths, which exhibit both electrical and optical behavior, making it difficult to develop suitable components and structures that can handle these signals effectively.
Innovation Solution
A transceiver device with a mixer/filter assembly coupled to an antenna cavity, capable of operating in both passive and active modes, processes sub-millimeter signals by using a block structure with cavities and filters to manage signal processing and transmission/reception, allowing for simultaneous or non-simultaneous signal transmission and reception, including passive reception of non-reflected signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional circuit techniques are used to process sub-millimeter signals, then the processing of signals with wavelengths of 1 millimeter or less becomes extremely difficult, but the use of conventional components and structures fails to effectively handle these signals
Solution Approach 1:
The patent replaces conventional electrical circuit techniques with electromagnetic resonance-based cavity structures. Instead of using traditional electrical components to process sub-millimeter signals, the invention employs resonant cavities that naturally support electromagnetic modes at sub-millimeter frequencies, effectively substituting electrical processing with electromagnetic field-based processing.
Solution Approach 2:
The patent changes the operating parameters from conventional electrical signal processing to electromagnetic resonance frequencies. By designing cavities with specific dimensions that resonate at sub-millimeter frequencies, the system adapts to handle these high-frequency signals through parameter changes in the electromagnetic field rather than through electrical circuit operations.
2Length of moving object
If components are made smaller to process higher frequency signals, then the physical size of components decreases, but the distinction between components and their interconnections becomes blurred
Solution Approach 1:
The patent merges the functions of separate components into integrated cavity structures. The resonant cavities serve multiple functions simultaneously - they are both the signal processing elements and the interconnection medium, eliminating the need for distinct components and their complex interconnections at sub-millimeter scales.
Solution Approach 2:
The cavity structures serve multiple functions: they act as resonators for signal processing, as transmission lines for signal transport, and as coupling elements for interconnection. This multi-functionality reduces the overall device complexity by eliminating the need for separate specialized components for each function.
3Manufacturing precision
If signals with wavelengths of 1 millimeter or less are processed using conventional techniques, then the short wavelength characteristics make processing extremely difficult, but traditional components cannot effectively handle these sub-millimeter signals
Solution Approach 1:
The patent changes the processing approach from electrical signal manipulation to electromagnetic resonance utilization. By designing cavities with precise dimensional parameters that resonate at sub-millimeter frequencies, the system achieves high processing precision through geometric parameters rather than through complex electrical circuit operations that are difficult to manufacture at these scales.
