Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional terahertz generators using solid state lasers or electromagnetic induction are used, then terahertz waves can be generated, but the bandwidth is narrow and applicability is restricted
Solution Approach 1:
The patent changes the fundamental operating parameters by using oscillating charged particles instead of conventional laser or induction methods. By adjusting the oscillation frequency of charged particles in the electric field, the generator can produce terahertz waves across a broad frequency range (0.1-10 THz), resolving the narrow bandwidth limitation while maintaining reliable wave generation through controlled particle oscillation
2Power
If conventional terahertz generators are used, then terahertz waves can be generated, but power consumption is high
Solution Approach 1:
The patent replaces the mechanical/electromagnetic systems (lasers, induction coils) with a particle oscillation system. Charged particles oscillate in response to applied electric fields, converting electrical energy directly into electromagnetic radiation with minimal loss. This substitution dramatically reduces power consumption while maintaining efficient terahertz wave generation through the direct coupling between particle motion and field production
3Adaptability or versatility
If terahertz waves of different wavelengths are required for medical imaging, then various organs can be imaged, but existing generators with small bandwidth cannot satisfy the requirement
Solution Approach 1:
The patent creates a universal terahertz generator that can produce waves across the entire 0.1-10 THz spectrum by controlling the oscillation frequency of charged particles. A single device configuration can generate different wavelengths by adjusting the electric field frequency, eliminating the need for multiple specialized generators for different medical imaging applications while maintaining simplicity
