Transparent Back Panel Case with Overmolded Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device cases lack innovative decorative and protective features, particularly in providing a transparent or translucent back panel that enhances visual appeal and provides impact protection.
Innovation Solution
A case design featuring a resilient, flexible frame overmolded onto a transparent or translucent polycarbonate back panel with a beveled edge that absorbs and re-emits light, creating an edge glow effect, and includes adjustable button cutouts for accommodating different device button tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent or translucent back panel is used, then visual appeal and light interaction are improved, but impact protection capability is reduced
Solution Approach 1:
The case combines a transparent or translucent back panel made from polycarbonate or similar material with a frame overmolded onto it. This composite structure allows the back panel to provide visual appeal and light interaction while the frame provides additional structural support and impact protection, resolving the contradiction between transparency and strength.
2Ease of manufacture
If a single button design is used, then manufacturing simplicity is improved, but adaptability to different device button tolerances is reduced
Solution Approach 1:
The button is designed with a resilient or flexible material that allows it to dynamically adapt to different button positions and tolerances on various devices. This dynamic flexibility enables a single button design to accommodate multiple device variations without requiring multiple specialized buttons, maintaining manufacturing simplicity while improving adaptability.
3Strength
If the frame is rigid, then structural strength is improved, but flexibility and resilience are reduced
Solution Approach 1:
The frame is constructed from resilient or flexible material that can change its mechanical parameters under different conditions. During normal use, the frame maintains sufficient structural strength, but under impact conditions, the material's flexibility allows it to absorb and dissipate impact energy, preventing damage to the device. This parameter change capability resolves the contradiction between rigidity and impact resistance.
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 provides a visually appealing, impact-resistant case with adjustable button compatibility and a unique edge glow effect, enhancing both functionality and aesthetics.
Implementation Method 1
The back panel is configured to absorb, internally reflect and re-emit light particles so as to provide unique visual observations when viewing the back panel or bevel thereof
Implementation Method 2
The back panel is configured to absorb, internally reflect and re-emmit light particles
Implementation Method 3
The frame is generally overmolded onto the front or interior surface of the back panel

AI summary
An electronic device case with a transparent or translucent back panel. The case generally comprises a frame, configured to surround the outer periphery of the electronic device, coupled to a back panel, configured to cover the back of the electronic device. The frame generally includes a plurality of outer sidewalls surrounding a center cutout. The back panel is formed from a hard plastic material such as polycarbonate. In example embodiments, the back panel material is a clear, transparent material. In other embodiments, the back panel material is a tinted or translucent material. The frame is generally overmolded onto the front or interior surface of the back panel.
