Solution Overview

Problem

Current beam steering technologies for electromagnetic radiation, such as light, face limitations including narrow angular range, polarization dependence, high loss, and inefficiency with broad spectral bandwidths, particularly in optical systems.

Innovation Solution

The use of electronically controlled soft matter structures, including Liquid Phase Beam Steering, Solid Phase Beam Steering, Gas Phase Beam Steering, and Plasma Phase Beam Steering, which manage wave energy through Total Internal Reflection, refraction, or diffraction, allowing for continuous and precise steering and focusing of waves over large angular ranges without substantial loss.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If conventional beam steering technologies are used, then beam direction can be controlled, but the angular range is limited and loss increases

Engineering Contradiction:
Improveangular rangeVSAvoidbeam loss
Core Design Contradiction:
Length of moving objectVSLoss of energy

Solution Approach 1:

The patent changes the refractive index parameter of the soft matter material dynamically to achieve beam steering. By adjusting the refractive index through electrical control, the system achieves wide angular deflection without the mechanical limitations and losses of conventional systems, resolving the contradiction between angular range and energy loss

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces mechanical beam steering mechanisms with an electronically controlled soft matter system. This substitution eliminates mechanical wear and friction losses while achieving broader angular control, directly addressing the contradiction between angular range and energy loss

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If conventional optical beam steering is used, then polarization control is achieved, but the system becomes polarization dependent

Engineering Contradiction:
Improvepolarization controlVSAvoidpolarization independence
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent changes the optical parameter (refractive index) of the soft matter rather than relying on polarization-dependent effects. This parameter change approach makes the beam steering polarization-independent, allowing the system to handle both polarized and unpolarized light equally well, thus resolving the contradiction between polarization control and polarization independence

Inventive Principle:
Principle #35Parameter changes

3Productivity

If narrow-band phased array systems are used, then beam steering is achieved, but bandwidth is limited

Engineering Contradiction:
Improvebeam steering capabilityVSAvoidspectral bandwidth
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent uses refractive index changes in soft matter that are broadband in nature, unlike narrow-band phased array systems. This allows the system to steer beams across a wide spectral bandwidth while maintaining steering capability, resolving the contradiction between productivity and adaptability to different wavelengths

Inventive Principle:
Principle #35Parameter changes
