Fibre Optic Watch Glass for Reflection-Free Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional watches with protective glass suffer from reduced legibility and aesthetic appeal due to multiple light reflections and limited viewing angles, which affect contrast and require the wearer to adjust their wrist position for optimal viewing.
Innovation Solution
A fibre optic glass plate is used to project display information onto its top surface, eliminating reflections and providing an original aesthetic appearance by concealing the space between the display and glass, allowing for improved reading comfort and contrast regardless of viewing angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a protective glass is mounted at a certain distance from the display device, then the aesthetic appearance is improved by creating space, but the legibility deteriorates due to multiple light reflections and reduced viewing angle
Solution Approach 1:
A plate formed of a fibre optic group is introduced as an intermediary element between the display device and the external environment. This plate projects the displayed information onto its top surface, serving as a mediator that eliminates multiple reflections while maintaining aesthetic appearance. The fibre optic structure acts as the intermediary that transfers and projects images without the harmful optical effects of conventional protective glass.
Solution Approach 2:
The patent changes the optical parameters of the protective element by using a fibre optic group structure instead of conventional glass. This fundamental parameter change transforms how light interacts with the protective element, projecting images onto the top surface rather than allowing multiple reflections, thereby improving legibility while maintaining aesthetic appearance.
2Shape
If the distance between the protective glass and display device is increased, then the aesthetic appearance is enhanced, but the contrast and viewing angle are reduced due to parasitic reflections
Solution Approach 1:
The fibre optic plate serves as an intermediary that projects displayed information directly onto its top surface, eliminating parasitic reflections that would otherwise reduce contrast. This intermediary structure maintains high contrast and viewing angle quality while allowing aesthetic enhancement through the plate's design.
3Reliability
If conventional protective glass is used, then protection is provided, but parallax errors occur requiring specific viewing orientation
Solution Approach 1:
The fibre optic plate acts as an intermediary projection surface that displays information on its top surface, eliminating parallax errors inherent in conventional glass mounting. This allows readers to view information comfortably from various angles without requiring specific viewing orientations, while the plate itself provides protective function.
