Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If mechanical supports with fixed conductive traces are used, then structural stability is provided, but flexibility and adaptability of conductivity paths deteriorate
Solution Approach 1:
The patent applies the dynamics principle by making the conductivity paths dynamically reconfigurable through optical control. The photosensitive layer contains materials that change their electrical conductivity state in response to light illumination, allowing the transmission line paths to be dynamically created, modified, or deleted without mechanical movement or repositioning. This resolves the contradiction by providing both structural stability (the physical layer remains fixed) and flexibility (the conductivity paths can be reconfigured on demand through optical signals).
Solution Approach 2:
The patent utilizes parameter changes by altering the electrical conductivity parameter of the photosensitive material through optical illumination. When illuminated, the photosensitive material transitions between conductive and insulating states, enabling dynamic routing of transmission lines. This allows the system to maintain structural stability while achieving adaptability through controlled changes in the electrical properties of specific regions within the mechanical support.
2Adaptability or versatility
If discrete components such as switches are added to control connectivity, then adaptability of conductivity paths improves, but device complexity increases
Solution Approach 1:
The patent merges the functions of the mechanical support structure and the conductivity control mechanism into a single integrated system. The photosensitive layer is incorporated directly within the mechanical support, combining structural support and routing control functions. This eliminates the need for separate discrete switches and control components, reducing device complexity while maintaining full adaptability of conductivity paths through optical control.
Solution Approach 2:
The photosensitive layer serves multiple functions simultaneously: it provides mechanical support structure, acts as the conductive medium for transmission lines, and functions as the switching mechanism through optical response. This multi-functionality eliminates the need for separate discrete components, reducing overall device complexity while maintaining the ability to dynamically control conductivity paths.
3Adaptability or versatility
If jumper wires are added to implement alternate routing, then adaptability improves, but connection integrity and reliability deteriorate
Solution Approach 1:
The patent extracts the need for physical jumper wires and discrete connection components by implementing routing changes within the planar structure of the mechanical support itself. The photosensitive layer enables alternate routing paths to be created or activated within the same layer, eliminating the need to physically add or remove wire connections. This maintains connection integrity and reliability while providing routing flexibility.
