Solution Overview

Problem

Current technologies fail to create a compelling interactive virtual world experience akin to the 'holodeck' concept, lacking the ability to stimulate human sensory receptors effectively, particularly in visual, auditory, somatosensory, gustatory, olfactory, and vestibular systems, due to limitations in resolution, image quality, and seamless energy surface fabrication.

Innovation Solution

A transparent energy relay waveguide system using a 4D plenoptic function to direct energy through arrays of waveguides, combined with energy modulation elements like LCD, LED, OLED, and LCOS, to achieve holographic opacity modulation and bi-directional energy propagation, enabling immersive holographic, virtual, and augmented reality experiences without external accessories.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional display technologies are used, then device complexity is reduced, but sensory resolution and image quality fail to exceed human sensory capabilities

Engineering Contradiction:
Improvesensory resolutionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the display function into multiple independent waveguide channels, each handling specific spatial and angular information. This segmentation enables parallel processing of light field data across multiple dimensions, achieving high sensory resolution through distributed optical paths rather than a single complex display surface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from 2D display surfaces to 4D plenoptic space by incorporating spatial (x,y) and angular (theta,phi) dimensions. This dimensional expansion allows the system to encode and decode light field information in a way that exceeds human sensory resolution while maintaining manageable device complexity through structured optical geometry.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If waveguide arrays with multiple modulation elements are implemented, then holographic opacity modulation and binocular disparity are achieved, but manufacturing precision requirements increase

Engineering Contradiction:
Improveholographic opacity modulation capabilityVSAvoidwaveguide alignment precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The system introduces intermediate optical elements such as beam splitters, combiners, and relay optics between the waveguide arrays and modulation elements. These intermediaries act as mediators that tolerate manufacturing variations by providing optical path compensation and alignment buffering, enabling holographic opacity modulation without requiring extreme manufacturing precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs adjustable optical parameters including waveguide thickness, refractive index profiles, and modulation element positioning that can be tuned post-manufacturing. These parameter changes allow compensation for fabrication tolerances while maintaining the desired holographic opacity modulation and binocular disparity effects.

Inventive Principle:

Solution Approach 1:

The system merges the forward and inverse 4D plenoptic transformation functions into an integrated waveguide relay architecture. By combining these functions in a cascaded configuration where the output of one stage feeds into the next, the system achieves seamless energy surface stability while consolidating control logic and reducing overall system complexity compared to separate independent systems.
