Hidden Light-Emitting Element Lens Routing for Mobile Terminal Aesthetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals with light-emitting elements, such as flashlights or fill lights, compromise the aesthetic appearance as the light-emitting elements can be observed from the outside, affecting the device's overall design.
Innovation Solution
Incorporating a lens within the mobile terminal that surrounds the light-emitting element and changes its propagation direction, allowing light to exit from the device through specific surfaces while keeping the element hidden from view, thereby enhancing the device's aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the light-emitting element is positioned directly on the surface of the mobile terminal for light emission, then the light emission function is achieved, but the aesthetic appearance is compromised as the light-emitting element is visible from the outside
Solution Approach 1:
The light-emitting element is nested within the mobile terminal housing, surrounded by the first surface, second surface and side peripheral surface. The lens is positioned within the terminal to guide light from the hidden light-emitting element through the housing surfaces, achieving both aesthetic concealment and functional light emission
Solution Approach 2:
The lens acts as an intermediary component that receives light from the light-emitting element and redirects it through the housing surfaces. The orthographic projection region of the light-emitting element is positioned outside the orthographic projection region of the lens, allowing the lens to mediate light transmission while the light-emitting element remains hidden from external observation
2Shape
If the light-emitting element is hidden within the mobile terminal to improve aesthetics, then the appearance is enhanced, but the light emission path becomes more complex requiring additional optical components
Solution Approach 1:
The lens serves multiple functions: it guides light from the hidden light-emitting element, redirects light through specific housing surfaces (first surface, second surface, or both), and maintains a compact structure within the terminal. This multi-functionality reduces the need for additional optical components that would otherwise be required to achieve the same light emission patterns
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 effectively hides the light-emitting element from external observation, improving the mobile terminal's appearance while enabling light to exit through strategically designed surfaces for functional purposes like flash or fill lighting.
Implementation Method 1
The lens includes a light-outgoing surface that emits light towards the first surface, the second surface, or the first surface and the second surface. Light emitted from the light-emitting element is capable of exiting from the first surface, the second surface, or the first surface and the second surface through the light-outgoing surface of the lens.

AI summary
Provided is a mobile terminal, which has a first surface and a second surface that are opposite to each other, and a side peripheral surface connecting the first surface with the second surface. A lens and a light-emitting element are provided within the mobile terminal. The light-emitting element is positioned in the mobile terminal. The lens includes a light-outgoing surface that emits light towards the first surface and/or the second surface. The light emitted from the light-emitting element is capable of exiting from the first surface and/or the second surface through the light-outgoing surface of the lens. An orthographic projection region of the light-emitting element on a reference plane is located outside an orthographic projection region of the light-outgoing surface of the lens on the reference plane. The reference plane is a geometric plane perpendicular to a thickness direction of the mobile terminal.
