Integrated Light Guide Module with Dual-Layer Refraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of fabricating light guide modules is increased due to the non-integrated nature of light guide elements and cover lenses, and input devices like keyboards lack the ability to arbitrarily change button textures or figures, which is necessary for high-level applications such as eSports keyboards.
Innovation Solution
A light guide module is designed with a first light guide layer and a second light guide layer, where the refractive index of the first layer is greater than the second, allowing for improved light transmission and uniformity, and integrated with a reflective display panel, enabling the display module to control button figures arbitrarily through a system circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a light guide element is adhered with a cover lens to protect the surface, then the surface protection is improved, but the fabrication process complexity increases
Solution Approach 1:
The patent integrates the light guide element and cover lens into a single molded structure. The light guide element includes an integrated body portion and a protruding cover lens portion that extends from the body, eliminating the need for separate assembly steps. This merging of components maintains surface protection functionality while significantly simplifying the fabrication process by reducing the number of parts and assembly operations required.
2Ease of manufacture
If figures or textures on keyboard buttons are fixed, then the manufacturing process is simple, but the adaptability for different user settings is reduced
Solution Approach 1:
The patent enables dynamic reconfiguration of button textures by integrating a reflective display panel with the keyboard button structure. The display panel can dynamically change the visual appearance of buttons to display different figures, textures, or backlight patterns based on user settings or game modes. This dynamic capability allows the keyboard to adapt to different user preferences and applications while maintaining a relatively simple manufacturing process by using standard display components.
