Floating Image Generation Device With Angled Light Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional floating image generation devices are limited in displaying floating images outside the straight-ahead range of the light source, resulting in poor user experience as users cannot see the images clearly if their eyes are not aligned with the light source.
Innovation Solution
The floating image generation device incorporates a light source, an image generating module, and an image angle adjusting unit, where the image generating module and image angle adjusting unit are positioned parallel to the light source with a gap between them, allowing light to pass through and create a deflection angle, enabling floating images to be displayed outside the straight-ahead range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the floating image generation device uses a conventional configuration with the image generating module positioned directly in front of the light source, then the device structure is simple, but the viewing angle is limited and users cannot see the floating images clearly if their eyes are not aligned with the light source
Solution Approach 1:
The patent introduces an image angle adjusting unit that deflects light at an angle θ relative to the normal line of the light source, transitioning the light path from a one-dimensional straight-ahead direction to a two-dimensional angled path. This dimensional change in light propagation enables the floating image to be positioned outside the straight-ahead range, expanding the viewing angle without significantly complicating the overall device structure.
Solution Approach 2:
The image angle adjusting unit acts as an intermediary component between the light source and the image generating module. This mediator deflects the light emitted by the light source at a specific angle, enabling the floating image to be displayed at an angled position rather than directly in front of the light source, thus resolving the contradiction between simple structure and wide viewing angle.
2Adaptability or versatility
If the image generating module is positioned parallel to the light source with an image angle adjusting unit, then the floating image can be displayed outside the straight-ahead range, but the device complexity increases
Solution Approach 1:
The image angle adjusting unit serves multiple functions: it deflects light at an angle to position the floating image outside the straight-ahead range, and it maintains the parallel arrangement of the image generating module relative to the light source. This multi-functionality reduces the need for additional complex components while achieving flexible image display positioning.
3Ease of operation
If users view the floating image from positions not aligned with the light source, then user comfort is improved, but the image clarity deteriorates in conventional devices
Solution Approach 1:
The patent replaces the mechanical alignment requirement (where users must position their eyes directly in front of the light source) with an optical solution. The image angle adjusting unit optically deflects the light path at angle θ, allowing users to view the floating image from positions not aligned with the light source while maintaining image clarity through proper optical design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows users to see complete floating images outside the straight-ahead range of the light source, enhancing user experience by providing a wider viewing angle and improved interaction with the floating images.
Implementation Method 1
A light emitted by the light source passes through the image generating module and the image angle adjusting unit to generate a floating image
Implementation Method 2
There is an image deflection angle between the normal line of the light source and the path of the light emitted by the light source after the light emitted by the light source passes through the image generating module and the image angle adjusting unit
