Adjustable Optical Engine Mounting for Head-Mounted Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted display devices struggle to accommodate individual differences in interpupillary distance and field of view, leading to inconsistent display positioning and discomfort for users.
Innovation Solution
A display device with a mounting base, optical engine, and adjustable connecting portions that clamp the optical lens, allowing the mounting base to move relative to the lens for precise adjustment of the optical engine's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the optical engine is fixed in a fixed position, then the device structure is simple, but different users with different interpupillary distances and field of view cannot achieve accurate display positioning
Solution Approach 1:
The patent implements adjustability by allowing the optical engine to move relative to the lens along the optical path. The mounting base is designed with movable mounting portions that enable the optical engine to be positioned at different locations, transforming the fixed structure into a dynamic one that can adapt to different users' interpupillary distances and field of view requirements.
2Ease of operation
If the optical engine position is adjustable, then different users' viewing needs are met, but the device structure becomes complex
Solution Approach 1:
The mounting base is divided into a body portion and multiple mounting portions that are separately configured. The optical engine is mounted on specific mounting portions that allow independent adjustment. This segmentation enables the adjustment function to be implemented in a modular way, reducing overall structural complexity while maintaining adjustability.
Solution Approach 2:
The mounting base is designed as a universal platform that can accommodate different optical engine positions and orientations. The same mounting base structure serves multiple functions: supporting the optical engine, enabling positional adjustment, and adapting to different lens configurations, thereby avoiding the need for multiple specialized components.

AI summary
A display device includes: a mounting base; an optical engine mounted on the mounting base; a first connecting portion arranged on the mounting base and configured to be connected to a first side of the lens; and a second connecting portion arranged opposite to the first connecting portion and configured to be connected to a second side of the lens, the first side and the second side of the lens being opposing sides. The first connecting portion and the second connecting portion are configured to clamp the lens and allow the mounting base to move on the lens, to adjust a position of the optical engine relative to the lens.
