Solution Overview

Problem

Current incident-energy shaping technologies lack the ability to programmatically and dynamically control the shape of energy shapers for efficient energy steering and manipulation, particularly in optical and acoustic applications.

Innovation Solution

A programmable, deformable incident-energy shaper comprising a base, a protrusion, a deformable layer, and an actuator, where the deformable layer is suspended between the base and protrusion, capable of flexing inwardly or outwardly, and is operatively coupled with an actuator to change its shape in response to electric potential or fluid control, enabling flexible refracting and diffraction of energy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a rigid, fixed-geometry energy shaper is used, then the structural stability is maintained, but the adaptability to different energy shaping requirements is limited

Engineering Contradiction:
Improveadaptability to energy shaping requirementsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the energy shaper's geometry changeable through the incorporation of a deformable layer that can be actuated to transition between different shapes. This allows the device to adapt its refractive properties dynamically rather than being fixed, resolving the contradiction between adaptability and complexity by introducing controlled variability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by enabling the energy shaper to alter its geometric parameters (shape, curvature, volume) through actuation of the deformable layer. This allows continuous adjustment of energy shaping parameters without changing the fundamental device structure, thereby improving adaptability while managing complexity through parameter modulation rather than structural redesign.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If a deformable layer is added to enable dynamic shaping, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improvedynamic shaping capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the flexible shells and thin films principle by using a deformable layer as a flexible membrane that can be actuated to change the geometry of the energy shaper. This thin, flexible structure enables dynamic shaping capability while adding minimal complexity compared to entirely rigid reconfigurable structures, as the deformable layer simply needs to be actuated rather than completely reconfigured.

Inventive Principle:
Principle #30Flexible shells and thin films

3Ease of operation

If the deformable layer is suspended in free space, then the ease of operation is improved, but the manufacturing precision becomes more difficult to achieve

Engineering Contradiction:
Improveease of operationVSAvoidmanufacturing precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies segmentation by dividing the energy shaper into distinct components: a base structure and a separate deformable layer. This segmentation allows the deformable layer to be manufactured and attached independently, improving ease of operation by enabling modular assembly while maintaining manufacturing precision through standardized attachment interfaces and separate manufacturing processes for each component.

Inventive Principle:
Principle #1Segmentation
