Optical Illusion 3D Design in Electronic Device Cases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device cases lack innovative 3D design elements that are both aesthetically appealing and cost-effective to manufacture, as they either require actual embedded 3D features or rely on simple decorative elements.
Innovation Solution
The use of a two-layered back panel system with 3D shaped impressions on one layer and corresponding design features on another, creating an optical illusion of embedded 3D elements through alignment and reflective coatings, without the need for actual 3D features, achieved by injection molding and assembly techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If actual 3D design elements are embedded in the case, then aesthetic appeal is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The patent uses 3D shaped impressions (molds) formed directly into the back plate material to create the appearance of embedded 3D elements. Instead of embedding actual 3D objects, the invention creates negative impressions that visually replicate the appearance of embedded gems or crystals when viewed from the front, significantly reducing manufacturing cost and complexity while maintaining aesthetic appeal
Solution Approach 2:
The patent creates a two-dimensional representation of three-dimensional elements by forming 3D shaped impressions on the back plate surface. These impressions are cross-sectional views of what would appear as 3D elements from the front, effectively using a 2D manufacturing approach to achieve a 3D visual effect
2Shape
If actual 3D design elements are embedded in the case, then aesthetic appeal is improved, but device complexity increases
Solution Approach 1:
The invention replaces complex embedded 3D objects with simple 3D shaped impressions molded directly into the back plate. This copying approach eliminates the need for separate embedding processes, alignment mechanisms, and securing structures, thereby reducing device complexity while preserving the visual appearance of embedded elements
Solution Approach 2:
The patent merges the decorative function and structural function into a single integrated back plate. The 3D shaped impressions are formed as part of the back plate manufacturing process itself, combining what would otherwise be separate components (back plate and embedded decorative elements) into one unified structure
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
This solution provides a cost-effective and visually striking appearance of 3D design elements, such as gems or crystals, on the case without the expense of embedding actual objects, enhancing the aesthetic appeal while maintaining structural integrity.
Implementation Method 1
applying a reflective coating to the at least one first impression

AI summary
A case having the appearance of 3D design elements embedded therein. The case generally comprises a back panel which incorporates a plurality of layers with impressions or recesses formed thereon. When aligned, the impressions create an optical illusion as if actual objects are embedded in the back panel of the case where no actual object is present. And a method of producing an optical illusion of embedded design elements in a case including the steps of forming a first panel with at least one first impression formed on a first side of the first panel, applying a reflective coating to the at least one first impression, forming a second panel, and joining the second panel to the first side of the first panel.
