Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protection elements are added to protect the terahertz element from static electricity, then reliability is improved, but device complexity increases
Solution Approach 1:
The rectifying elements are integrated directly into the terahertz device structure, combining protection functionality with the existing device architecture. The rectifying elements are electrically connected in parallel to the terahertz element, merging the protection function into the core device structure rather than adding separate external protection components.
Solution Approach 2:
The rectifying elements serve multiple functions: they protect against static electricity damage while also potentially influencing the electrical characteristics of the terahertz element. This multi-functionality reduces the need for dedicated separate protection components, thereby limiting complexity increase.
2Reliability
If protection elements are added to protect the terahertz element from static electricity, then reliability is improved, but device size increases
Solution Approach 1:
The rectifying elements are positioned in close proximity to the terahertz element, with one rectifying element disposed at a first position and the other at a second position relative to the terahertz element. This nested arrangement allows the protection elements to be integrated within or alongside the existing device footprint rather than requiring additional external space.
Solution Approach 2:
The protection functionality is merged into the existing device structure through direct electrical connection and spatial integration, avoiding the need for separate external protection components that would increase device size.
3Reliability
If rectifying elements are connected in parallel to regulate current flow, then protection effectiveness is improved, but device complexity increases
Solution Approach 1:
The parallel connection of rectifying elements is integrated directly into the terahertz device circuitry, combining current regulation functionality with the existing electrical structure. The rectifying elements are electrically connected in parallel to the terahertz element, merging protection circuitry with the core device structure.
