Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical switching systems are limited in their ability to perform multiple sub-pathway switching and handling multiple lasers or beams of light without compromising switching speed, and they often generate heat, consume power, and radiate noise due to 90-degree bends in conductive traces.
Innovation Solution
A bicontinuous optical switching system with hyperbolic surfaces that utilize a large number of switching channels with mutually interpenetrating labyrinths, allowing photons to travel through a primary path defined by geometric optics and providing multiple sub-pathways without impeding signal transmission, and can be coated with reflective materials for enhanced performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional optical switching systems use traditional conductive trace structures with 90-degree bends, then electrical connectivity is achieved, but heat generation, power consumption, and noise increase
Solution Approach 1:
The patent transitions from planar two-dimensional conductive traces to three-dimensional bicontinuous structures. The conductive elements are arranged in interpenetrating labyrinths that extend through the thickness of the substrate, creating a volumetric network that reduces current path length and eliminates sharp bends, thereby reducing resistive heating and power consumption while maintaining connectivity.
Solution Approach 2:
The patent replaces sharp 90-degree angular bends in conventional traces with smooth curved pathways in the three-dimensional bicontinuous structure. The curved conductive paths reduce electromagnetic radiation and signal interference while maintaining electrical connectivity, thereby reducing noise and improving signal integrity.
2Adaptability or versatility
If conventional optical switching systems use simple two-dimensional layouts, then manufacturing is easier, but multiple sub-pathway switching and handling of multiple lasers are limited
Solution Approach 1:
The patent divides the switching function into multiple independent switching channels, each capable of handling separate laser beams or light paths. The bicontinuous structure provides distinct interpenetrating labyrinthine pathways that can be independently controlled, enabling simultaneous multiple sub-pathway switching operations without interference between channels.
Solution Approach 2:
The patent implements nested three-dimensional structures where conductive elements and optical pathways are embedded within the volumetric bicontinuous architecture. Multiple switching channels are nested within the same substrate volume, with each channel having its own controlled pathways, thereby achieving high versatility without increasing footprint.
3Productivity
If conventional systems use planar circuit architectures, then substrate utilization is simple, but connectivity and wire lengths are suboptimal
Solution Approach 1:
The patent utilizes the third dimension (substrate thickness) to create direct vertical and diagonal connections between circuit elements. The three-dimensional bicontinuous structure allows conductive pathways to traverse through the substrate volume rather than traveling across the surface, dramatically reducing wire lengths and improving signal transmission efficiency by eliminating long lateral routes.

AI summary
A three-dimensional circuit includes a hyperbolic bicontinuous structure forming a substrate; circuits formed on a first surface of the hyperbolic bicontinuous structure; and electrically conductive traces formed between the circuits. The electrically conductive traces are formed two-dimensionally on the first surface of the hyperbolic bicontinuous structure.
