Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional transceiver devices use silicon lens for THz extraction, then THz radiation can be extracted into free-space, but the system size increases and manufacturing complexity increases
Solution Approach 1:
The patent removes the silicon lens component from the conventional transceiver design. The TBRTD device directly generates and radiates THz waves into free-space without requiring external lens extraction, thereby eliminating the associated manufacturing complexity and reducing overall system volume.
Solution Approach 2:
The TBRTD device performs multiple functions: it generates THz radiation and simultaneously radiates it into free-space through its integrated antenna structure. This multi-functionality eliminates the need for separate lens components, simplifying the overall device architecture and reducing system size.
2Quantity of substance
If wireless network bandwidth is limited, then existing infrastructure can be maintained, but the number of sensors connected in fusion networks is restricted
Solution Approach 1:
The patent employs TBRTD devices operating at terahertz frequencies (0.2 to 0.6 THz), representing a significant parameter change from conventional wireless communication frequencies. This frequency parameter change enables hundreds of gigabytes of data transfer per second, allowing numerous sensors to be connected in fusion networks without bandwidth limitations.
3Ease of manufacture
If terahertz transceiver uses matured planar IC fabrication processes, then manufacturing cost decreases and scalability increases, but device performance must be maintained at micrometer scale
Solution Approach 1:
The transceiver is designed as a segmented integrated circuit with distinct functional modules: TBRTD active regions, resonator antenna, and radiator antenna. Each segment can be fabricated using standard planar IC processes, allowing precise control at micrometer scale while maintaining manufacturing scalability and cost-effectiveness.
Solution Approach 2:
The patent transitions from three-dimensional component assembly to two-dimensional planar integration. All components (TBRTD, resonator antenna, radiator antenna) are fabricated in the same plane using standard IC processes, eliminating the need for complex 3D assembly and enabling precise dimensional control at micrometer scale.
