Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the distance between adjacent terahertz elements is reduced to improve resolution, then the resolution in the detection range is improved, but the electromagnetic wave transmission between elements may be interfered with
Solution Approach 1:
A reflective surface is introduced as an intermediary component between adjacent terahertz elements. This reflective surface reflects electromagnetic waves toward the elements, enabling the elements to be arranged closer together for improved resolution while the reflective surface manages the electromagnetic wave paths to prevent harmful interference between elements.
Solution Approach 2:
The reflective surface is designed with a curved shape (concave or convex) rather than being flat. This curvature allows the reflective surface to effectively redirect electromagnetic waves from adjacent elements, enabling compact arrangement of elements while maintaining proper wave propagation paths and preventing interference.
2Area of stationary object
If multiple terahertz elements are arranged closely to improve resolution, then the device structure becomes more compact, but the complexity of arranging and coordinating the elements increases
Solution Approach 1:
The reflective surface serves multiple functions simultaneously: it reflects electromagnetic waves toward terahertz elements, enables compact arrangement of elements, and coordinates wave paths between multiple elements. This multi-functionality reduces the need for additional complex components while achieving compact device structure.
3Power
If the reflective surface is made larger to improve electromagnetic wave reflection, then the reflection efficiency is improved, but the distance between adjacent terahertz elements cannot be reduced
Solution Approach 1:
By curving the reflective surface, the patent achieves efficient electromagnetic wave reflection without requiring a large surface area. The curvature concentrates and directs wave energy effectively, allowing compact arrangement of terahertz elements while maintaining high reflection efficiency and electromagnetic wave output.
Solution Approach 2:
The reflective surface utilizes three-dimensional curvature rather than being limited to a flat two-dimensional plane. This dimensional approach allows the surface to achieve effective wave reflection in a compact space, enabling reduced distance between elements while maintaining high electromagnetic wave output.
