Slide Unit Guide Structure for Adjustable Eye Relief in VR Headsets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices for Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) face challenges in adjusting the distance between the display unit and the user's eyes, particularly when wearing glasses, which affects the optimal eye relief and comfort.
Innovation Solution
An electronic device with a slide unit that allows the display unit to be relatively movable with respect to the support unit, featuring a base with outer and inner guide portions and a slide member with corresponding guide protrusions and slits, enabling adjustable distance settings through a sliding mechanism controlled by sensors or user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed connection structure is used between support unit and display unit, then device structure is simple, but eye relief distance cannot be adjusted for users wearing glasses
Solution Approach 1:
The connection structure is transformed from a fixed state to a movable state by introducing a slide unit with guide portions and guide protrusions. The display unit can slide relative to the support unit along the movement direction, enabling dynamic adjustment of eye relief distance while maintaining a relatively simple overall structure.
Solution Approach 2:
The connection structure is divided into separate components: a base with guide portions and a slide member with guide protrusions. This segmentation allows independent movement of the display unit while maintaining structural integrity, resolving the contradiction between adjustability and structural simplicity.
2Reliability
If a single guide portion is used in the connection structure, then structure is simple, but stability and support during sliding movement are insufficient
Solution Approach 1:
The guide structure is segmented into multiple guide portions (first and second guide portions) positioned at different locations. Each guide portion works independently to constrain and guide the sliding movement, providing enhanced stability without requiring a completely complex new structure.
Solution Approach 2:
The guide portions are arranged in different spatial positions and orientations, adding dimensional complexity to the guidance system. This multi-dimensional arrangement ensures stable sliding movement while keeping individual guide portions relatively simple in design.
