Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices incorporating projectors face challenges in enhancing designability and diversity of display manner while maintaining visual effects, particularly due to increased depth requirements and uneven brightness across the screen.
Innovation Solution
A display device featuring a non-planar screen surface and a light emission unit, where the screen can have a curved or concave shape and be replaceable, and the light emission unit is strategically placed to enhance visual effects and decorative elements, addressing brightness inconsistencies and design limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a projector is incorporated inside the display device to enlarge the display screen, then the display size can be increased at low cost, but the depth of the device has to be increased
Solution Approach 1:
The projector is nested inside the display device housing, with the light emission unit positioned within the casing and the screen forming part of the casing structure. This nesting arrangement allows the projector to be integrated without significantly increasing the external dimensions of the device, resolving the contradiction between display size and device depth.
2Illumination intensity
If the display surface has a non-planar shape to enhance visual effects and stereoscopic display, then visual effects and decorative effects are improved, but the device complexity increases
Solution Approach 1:
The display surface is designed with a non-planar curved shape, specifically a convex or concave curvature, to create stereoscopic visual effects and enhance decorative appearance. This curvature is achieved through the screen structure itself rather than complex optical components, improving visual effects while controlling device complexity.
Solution Approach 2:
The light emission unit serves multiple functions: it provides backlighting for the display screen, creates decorative lighting effects around the device, and enhances the stereoscopic perception through strategic illumination of the curved surface. This multi-functionality reduces the need for separate components, managing device complexity while achieving enhanced visual effects.
3Ease of manufacture
If the light emission unit is strategically placed to enhance visual effects, then decorative effects and attention capture are improved, but the device complexity increases
Solution Approach 1:
The light emission unit is strategically positioned at specific locations within the casing, such as behind or around the screen, to create localized illumination effects that enhance visual perception and decorative appearance. This selective placement of light sources provides design flexibility and enhanced visual effects without requiring complex illumination systems throughout the entire device.
