Electronic Device Cover with 3D Logo via Light Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic device covers with 2-D logos are ineffective in creating brand memory and 3-D logos are prone to damage and incur additional costs and electrostatic issues due to light holes, which also fail to achieve a true 3-D appearance.
Innovation Solution
A cover with an illumination device that uses light-blocking and light-passing regions on both inner and outer surfaces, where the light-blocking regions on the outer surface are smaller than their corresponding light-passing regions on the inner surface, creating a 3-D effect, and can be made with translucent coarse surfaces in an alternative embodiment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a 2-D logo is used on the cover, then it can be easily made and easily fixed to the cover, but it has little effect to engrave itself into memory and lacks three-dimensional appearance
Solution Approach 1:
The patent applies dimensionality change by creating a light-blocking region that protrudes from the inner surface of the cover body toward the outer surface. This protrusion creates a three-dimensional effect when light passes through the cover, transforming a traditionally two-dimensional logo into a three-dimensional visual element without requiring complex manufacturing processes.
2Shape
If a 3-D logo is made by recesses-cutting process, then it has three-dimensional appearance, but it involves extra process and cost and the logo is easily damaged by abrasion
Solution Approach 1:
Instead of cutting recesses into the cover to create a 3-D logo effect, the patent inverts the approach by adding a light-blocking region that protrudes from the inner surface. This inversion eliminates the need for complex recess-cutting processes while achieving the desired three-dimensional appearance through light interaction.
3Illumination intensity
If holes are provided to allow light to shine the logo, then the logo becomes more promotive, but the holes incur extra process and cost and can induce dust to get into the case resulting in electrostatic problem
Solution Approach 1:
The patent extracts the harmful element (holes) from the design while retaining the beneficial function (logo illumination). By using a light-blocking region with a protruding portion on the inner surface, the system eliminates the need for holes to shine light on the logo, thereby preventing dust ingress and electrostatic problems while maintaining logo visibility.

Function Achieved in This Case
The solution effectively creates a 3-D logo effect without additional costs and electrostatic issues, enhancing brand visibility while maintaining durability and reducing dust ingress.
Implementation Method 1
a body (11) installed inside and is penetrable by light yielded from an illumination device
Implementation Method 2
the body has an inner surface incorporating a material impenetrable by light as a light-blocking region (12) and the remaining of the inner surface defined as a light-passing region (14)

AI summary
A cover of an electronic device has a body inside and is penetrable by light yield from an illumination device. The body has an inner surface having a region impenetrable by light as a light-blocking region and the remaining region penetrable by light as a light-passing region. The body further has an outer surface having a region impenetrable by light as another light-blocking region and the remaining region penetrable by light as another light-passing region. The light-blocking region of the outer surface correspond to the light-passing region of the inner surface in shape, but in a size that is smaller, so that when light pass through the body, light can give an effect that the shape of the light-blocking region looks three-dimensional.
