Multi-Petal Swept Volume Display with Reimaging Glass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional volumetric displays require users to physically move around or rotate the display to view three-dimensional scenes from different angles, limiting interactive capabilities and requiring additional devices like glasses for a full 3D experience.
Innovation Solution
A volumetric display system utilizing a multi-petal rotating geometry with reimaging glass, such as Asukanet's aerial imaging glass, creates a floating 3D hologram viewable from various angles without glasses, allowing direct interaction by projecting images onto rotating petals and reimaging them in front of the display, enabling mid-air interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional volumetric display is used, then a true 3D volume can be displayed, but the user must physically move around or rotate the display to view different parts
Solution Approach 1:
The patent applies the dynamics principle by implementing a rotating structure with multiple petals that spin to dynamically generate different viewing angles. The rotation mechanism allows the display to actively change its orientation rather than requiring passive user movement, resolving the contradiction between viewing accessibility and device complexity.
Solution Approach 2:
The patent employs dimensionality change by using a multi-petal geometric structure that rotates in the spatial domain. This creates multiple viewing zones around the display volume, effectively adding angular dimensionality to the viewing experience without requiring linear physical movement of the entire display apparatus.
2Area of stationary object
If reimaging glass is used to create aerial images, then the field of view is limited
Solution Approach 1:
The patent applies segmentation by dividing the viewing experience into multiple discrete zones, each associated with a specific petal. As petals rotate into different positions, they sequentially present different viewing zones to the user. This segmentation allows the system to overcome the limited field of view of individual reimaging glass elements by providing multiple accessible viewing angles through temporal and spatial distribution.
Solution Approach 2:
The rotating petal structure dynamically expands the effective field of view by bringing different reimaging glass segments into the user's line of sight at different times. This dynamic reconfiguration allows versatile viewing angle access while maintaining the optical properties of each individual glass element.
3Adaptability or versatility
If a multi-petal rotating geometry is used, then multiple viewing angles are available, but mechanical noise increases
Solution Approach 1:
The patent applies mechanics substitution by replacing traditional high-speed rotating mechanisms with a slower-spinning multi-petal geometry. The increased number of petals allows each petal to be larger and heavier, enabling slower rotation speeds that reduce mechanical noise while still achieving the required volumetric refresh rates through the distributed petal structure.
4Ease of operation
If the display is moved or rotated to show different parts, then all parts can be viewed, but interaction complexity increases
Solution Approach 1:
The patent applies self-service by enabling the display structure to automatically present different viewing angles through its own rotation, without requiring external manipulation. The multi-petal geometry self-rotates to bring different facets into view, and the system autonomously manages the sequencing of viewing zones, reducing the need for complex user interaction mechanisms.
