Foldable Mobile Device with Cut Area Lens Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
All-screen smart mobile devices face challenges in hiding the front lens, storage, and design aesthetics, especially when folded, as the front lens disrupts the display area and optical substrate cutting, and existing solutions fail to efficiently address these issues.
Innovation Solution
A square or rectangular-shaped foldable mobile device design featuring notches or cut edges at the corners and center back, allowing the front lens to be hidden when folded, enabling a double-sided display and utilizing the rear lens as a front lens for improved storage and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a front lens is added to an all-screen device, then the device can capture front images, but the display area is reduced and aesthetics are compromised
Solution Approach 1:
The patent applies dynamics by making the lens cover movable rather than fixed. The lens cover can dynamically switch between covering and exposing the lens based on operational needs. When the screen is folded, the lens cover moves to expose the lens for selfies; when unfolded, it covers the lens to maintain the all-screen appearance. This dynamic mechanism resolves the contradiction between having front lens functionality and maintaining full display area.
2Area of stationary object
If the device is made with a large screen, then the display area is increased, but the device becomes harder to store
Solution Approach 1:
The patent applies dimensionality change by introducing a folding mechanism that transforms the device from a two-dimensional flat state to a three-dimensional folded state. The large screen can be folded along a hinge, effectively reducing its footprint for storage while maintaining the full display area when unfolded. This spatial transformation resolves the contradiction between large display area and compact storage requirement.
3Adaptability or versatility
If the front lens is positioned on the all-screen display, then front camera functionality is achieved, but the optical substrate cutting becomes more difficult
Solution Approach 1:
The patent applies the extraction principle by removing the lens from the main screen area and placing it in a separate, dedicated location on the folded portion of the device. The lens is extracted from the optical path of the main display, allowing the optical substrate to be cut and manufactured separately without interfering with the all-screen display structure. This resolves the manufacturing difficulty while preserving front camera functionality.
