VR Cell Phone Ocular Plate Distance Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual reality systems require separate devices for implementation, limiting convenience and portability.
Innovation Solution
A virtual reality cell phone integrating a main body with a display, an ocular plate, and a screen and distance adjustment member that allows the ocular plate to maintain a variable distance for optimal VR functionality, incorporating a light blocking mechanism and adjustable lenses for personalized fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual reality systems use separate devices, then VR functionality can be implemented, but portability and convenience are limited
Solution Approach 1:
The patent combines the virtual reality module with the smartphone body into an integrated structure. The VR module includes an ocular plate, display, and adjustment mechanisms that are built into the smartphone, eliminating the need for separate external devices while maintaining both VR functionality and portability.
Solution Approach 2:
The smartphone is designed to serve dual purposes: functioning as a standard mobile phone and as a virtual reality device. The integrated VR module allows the same device to provide both conventional smartphone operations and immersive VR experiences, making the system universally applicable for multiple functions.
2Device complexity
If the ocular plate is fixed at a set distance, then the structure is simple, but it cannot accommodate different user preferences for viewing distance
Solution Approach 1:
The ocular plate is designed with movable capability relative to the smartphone body through a ratchet mechanism. This allows the viewing distance to be dynamically adjusted by the user to different positions and then locked in place, providing adaptability while maintaining structural simplicity through the one-way locking mechanism.
Solution Approach 2:
The distance adjustment mechanism is segmented into discrete adjustable positions using a ratchet and pawl system. The ocular plate can be positioned at multiple fixed intervals, allowing users to select from several viewing distance options while keeping the overall structure simple and manufacturable.
3Device complexity
If external light can enter the VR module, then the structure is open and simple, but it reduces the immersion quality of VR experience
Solution Approach 1:
A flexible light-blocking screen is introduced between the smartphone display and the ocular plate. This thin film can be extended or retracted as needed, blocking external light when VR mode is active while allowing an open structure when not in use, thus maintaining structural simplicity while eliminating light interference during VR operation.

AI summary
A virtual reality cell phone includes: a main body including a display; an ocular plate configured to maintain a variable distance from the rear surface of the main body; and a screen and distance adjustment member interposed between the main body and the ocular plate, and configured to move the ocular plate between a retracted state in which the ocular plate comes into close contact with the main body and an extended state in which the ocular plate maintains a predetermined distance from the main body. The screen and distance adjustment member includes a plurality of screen boxes configured to slide backward and be fixed while being laid over each other.
