Luminous Keyboard Key with Integrated Light Shade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keyboard devices with indicating lamps occupy additional space, confuse users, and suffer from inefficient illumination due to misalignment or detachment of light shades, leading to reduced visibility of luminous keys.
Innovation Solution
A keyboard device with luminous keys featuring integrally formed elastic elements and light shades, where the light shades are securely attached to centralize light beams, ensuring proper illumination and reducing the risk of misalignment or detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If separate light shades are used for luminous keys, then light beams can be centralized and illumination improved, but light shades may detach or misalign reducing visibility
Solution Approach 1:
The patent combines the light shade and elastic element into a single integrated component. The light shade is formed as an integral part of the elastic element, eliminating the need for separate attachment and preventing detachment or misalignment issues while maintaining light centralization functionality
2Ease of operation
If indicating lamps are added to show key status, then user feedback is improved, but layout space is occupied and volume increases
Solution Approach 1:
The patent makes the keycap serve multiple functions: it acts as both the mechanical key component and the light-emitting indicator. The light-outputting zone is integrated into the keycap structure, allowing the same component to provide both tactile input and visual feedback without requiring separate indicating lamps
Solution Approach 2:
The patent extracts the indicating lamp function from a separate component and integrates it into the keycap itself. The light-emitting element and light-outputting zone are incorporated directly into the keycap structure, removing the need for additional indicating lamp components
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 secure fixation of light shades enhances the illuminating efficacy of luminous keys, improving user identification of key functions while minimizing space occupation and maintaining structural integrity.
Implementation Method 1
The at least one top-view light-emitting element is disposed under the corresponding first light-outputting zone for emitting at least one first light beam
Implementation Method 2
The at least one elastic element is disposed under the at least one keycap and contacted with the at least one keycap for providing an elastic force to the at least one keycap

AI summary
A keyboard device with a luminous key is provided. The keyboard device includes at least one luminous key, a top-view light-emitting element, and a light shade. The top-view light-emitting element is used for emitting a light beam. The light shade is used for shading the light beam. Moreover, the light beam is transmissible through a light-outputting part of the light shade to illuminate the luminous key. The at least one luminous key includes at least one keycap and at least one elastic element. The elastic element and the light shade are integrally formed with each other. Since the total area of the bottom surfaces of the elastic element and the light shade is increased, the light shade can be securely fixed.
