Reflective Polyurethane Leather for Camera-Only Holographic Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reflective materials on sports-related gear are visible to the naked eye and require external power sources to display vibrant colors, whereas there is a need for an article that produces a holographic effect only visible when recorded by a camera without requiring electricity.
Innovation Solution
A reflective leather material, such as polyurethane leather, is applied to sports-related gear, which appears non-descript to the naked eye but displays a colorful, illuminated, or holographic effect when recorded using a camera with a light source, eliminating the need for external power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If reflective materials are applied to display vibrant colors to the naked eye, then the article is visible and colorful, but it requires external power sources and is visible when not intended
Solution Approach 1:
The patent applies a reflective material that changes its optical properties based on the observer. To the naked eye, the material appears non-descript or matte, but when viewed through a camera lens with a light source, it reflects light to create vibrant holographic effects. This selective color change resolves the contradiction by making the article colorful only when intended (during camera recording) while maintaining a subdued appearance otherwise, eliminating the need for continuous power consumption.
Solution Approach 2:
The reflective material's reflectivity parameter is changed based on the observation method. The material has low reflectivity for direct human vision but high reflectivity for camera-based observation with light sources. This parameter change allows the article to consume no energy in normal conditions while displaying vibrant colors only during controlled recording scenarios.
2Illumination intensity
If reflective materials are applied to display vibrant colors, then the article appears colorful, but the effect is visible to the naked eye rather than being camera-specific
Solution Approach 1:
The reflective material exhibits different visual properties depending on the detection method. It appears non-descript to the naked eye but produces vibrant holographic colors when detected by a camera with a light source. This selective color change ensures the article displays vibrant colors only in the intended camera-recording context, resolving the visibility control issue.
3Illumination intensity
If traditional reflective materials are used, then the article displays colors continuously, but it cannot produce the holographic effect only on digital media
Solution Approach 1:
The reflective material is designed to change its optical characteristics based on the observation medium. It remains visually subdued to the naked eye but creates vibrant holographic effects specifically when captured by digital cameras. This adaptability allows the article to display colors continuously in the sense that the reflective property is always present, but the vibrant effect manifests only on digital media as intended.
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
The solution enables sports-related gear to showcase a holographic effect on digital media without visible illumination to the naked eye, enhancing social media content without power sources, allowing for visually striking images that 'go viral'.

Data Source
AI summary
A method for manufacturing an article that records a holographic image when photographed or videotaped but otherwise not visible to the naked eye. The article, such as a basketball, includes at least a layer of polyurethane leather that is reflective and is illuminated on photographic media when imaged. The illuminated or holographic image may be seen and displayed on a digital device, such as a social media platform.
