Pivoting Lens Cover for Mobile Camera Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with camera lenses face issues of lens fouling by fingerprints and privacy concerns due to their ubiquity and frequent handling.
Innovation Solution
A lens cover with a base ring and pivotally coupled flap that folds 180 degrees between open and closed positions to selectively expose or cover the camera lens, allowing for easy access and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a lens cover is added to protect the camera lens, then lens fouling and privacy concerns are addressed, but device complexity increases
Solution Approach 1:
The flap is designed to be pivotally coupled to the base ring, allowing it to dynamically transition between covering and exposed positions. This dynamic mechanism enables the lens cover to adapt between protection and accessibility states, resolving the contradiction by providing active control rather than a static cover structure.
Solution Approach 2:
The lens cover is segmented into two main components: a base ring that remains fixed and a flap that can move independently. This segmentation allows the protective function to be separated from the accessibility function, enabling the lens to be protected when needed while maintaining easy access when the flap is opened.
2Adaptability or versatility
If a flap mechanism is added to selectively cover the lens, then privacy control is improved, but ease of operation deteriorates
Solution Approach 1:
The flap mechanism is designed to be manually operable by the user without requiring additional tools or complex activation sequences. The pivotal coupling allows the user to easily open and close the flap with simple hand movement, maintaining ease of operation while providing adaptability for privacy control.
3Adaptability or versatility
If the flap is positioned to cover the lens in closed position, then privacy protection is improved, but device functionality deteriorates
Solution Approach 1:
The dynamic flap mechanism allows the system to switch between privacy protection mode (closed position) and functionality mode (open position). The pivotal coupling ensures smooth transition between these states, maintaining reliability by ensuring the lens is fully accessible when the flap is opened while providing complete privacy coverage when closed.

AI summary
A lens cover selectively covers and exposes a, camera lens on the back of mobile device, such as a cellular phone. The lens cover can be adhered to the back of the mobile device. The lens cover has a flap that pivots 180 degrees about an axis parallel with the back of the mobile device, and between an open/storage position and a closed position. The flap can be off-set with respect to the axle so that in the open/storage position, the flap is adjacent or abutting to the back of the mobile device, and so that in the closed position, the flap is spaced-apart from the back of the mobile device, creating a gap to receive a protruding camera or camera lens. The flap can also comprise a detent to maintain the flap in a selected position until selectively moved.
