Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional display devices, such as floating image display devices, face issues with high power consumption, increased volume and weight due to motor rotation, and decreased image quality due to separate components for the screen and mirrors, leading to vibration-related accuracy problems.
Innovation Solution
A three-dimensional display device utilizing a display panel that projects partial images along a circumference and an n-gonal pyramid mirror with mirrors at its sides, each making a 45-degree angle with the panel, to reflect and combine images, providing stable and natural floating images without the need for motor-driven rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a motor is used to rotate the screen, then the display device can show images in various directions, but power consumption increases and volume and weight increase
Solution Approach 1:
The patent replaces the motor-driven mechanical rotation system with a stationary optical system using an n-gonal pyramid mirror. The display panel remains fixed while the pyramid mirror's multiple reflective surfaces direct images to different viewing angles, eliminating the need for motor rotation and reducing power consumption.
Solution Approach 2:
The patent divides the single viewing direction into multiple segments by using an n-gonal pyramid mirror with n reflective surfaces. Each surface corresponds to a specific viewing direction, allowing the system to display images in various directions simultaneously without mechanical movement.
2Adaptability or versatility
If the screen rotates, then images can be viewed from different directions, but vibration occurs and accuracy of reflecting angle decreases
Solution Approach 1:
The patent eliminates the rotating mechanical screen system and replaces it with a stationary display panel combined with a fixed n-gonal pyramid mirror. This static configuration removes vibration entirely while maintaining precise reflecting angles through the rigid structural relationship between the display panel and pyramid mirror surfaces.
3Device complexity
If the screen and mirrors are located in different structural components, then the device structure is flexible, but accuracy of reflecting angle decreases and image quality decreases
Solution Approach 1:
The patent merges the display panel and pyramid mirror into an integrated optical system where the mirrors are positioned at specific angles relative to the display panel. This integration ensures precise reflecting angles while maintaining the functional separation of components, resolving the contradiction between structural flexibility and angular accuracy.
