Solution Overview

Problem

Existing transmission-type optical devices, such as head-mounted displays and projection mapping, face challenges in allowing multiple observers to share information simultaneously and in separating external information from projected information, leading to reduced visibility and mixed perception of both.

Innovation Solution

A transmission-type optical element with a substrate and information forming units that allow transmissivity in one direction while forming distinct information elements on orthogonal surfaces, enabling observers to view external information and information provided by the element as separate entities, with control systems for adjusting the optical element's position relative to the scene.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If information is displayed on a transmission-type display (head mounted display), then information visibility is improved, but external information visibility deteriorates

Engineering Contradiction:
Improveinformation visibilityVSAvoidexternal information visibility
Core Design Contradiction:
Loss of informationVSIllumination intensity

Solution Approach 1:

The invention transitions from displaying information on a flat transmission-type display surface to forming information elements on the side surfaces of three-dimensional information forming units. This dimensional change allows light to pass through the transparent substrate while reflecting off the side surfaces to display information, enabling both external visibility and information display simultaneously without the trade-off present in conventional transmission-type displays

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

2Productivity

If projection mapping directly projects videos on a structure, then information delivery is improved, but information separation deteriorates

Engineering Contradiction:
Improveinformation deliveryVSAvoidinformation separation
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The invention segments the display surface into multiple information forming units, each with side surfaces that can independently form information elements. This segmentation allows different regions to display different information content, enabling clear separation between structure-related information and projected information, unlike conventional projection mapping where all information is mixed on a single surface

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If a transmission-type device is attached to an individual observer, then information display is improved, but information sharing deteriorates

Engineering Contradiction:
Improveinformation displayVSAvoidinformation sharing
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The invention creates a universal information display system through transparent substrates with information forming units that can be integrated into various structures (buildings, vehicles, objects) rather than being limited to individual head-mounted devices. This allows multiple observers to simultaneously view the same information or different information displayed on different side surfaces, enabling both individualized and shared information access

Inventive Principle:
Principle #6Universality (Multi-functionality)
