Adjustable Headset Bumper Frame for Precise Smartphone Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays (HMDs) face challenges in securely accommodating smartphones of varying dimensions, leading to inconsistent and insecure positioning, which can result in image distortion and reduced virtual reality or augmented reality experience quality.
Innovation Solution
A dynamic frame system with adjustable bumpers and actuators that can translate, rotate, or deform to securely position smartphones of different sizes and shapes, ensuring accurate alignment and retention within the headset, using a combination of elastic-like tenting fabric and integrated bumpers to accommodate diverse phone profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the frame is oversized to accommodate different smartphone profiles, then the headset can support multiple phone sizes, but smaller phones cannot be properly positioned and securely retained
Solution Approach 1:
The bumper system employs movable bumpers that can dynamically adjust their positions along the frame to accommodate different smartphone sizes. The bumpers translate between retracted and extended positions, allowing the frame to adapt its internal dimensions while maintaining precise positioning for each device type
Solution Approach 2:
The system changes the positional parameters of the bumpers to match different smartphone profiles. By adjusting the location, extension distance, and orientation of bumpers, the frame can precisely accommodate various device dimensions while maintaining accurate positioning relative to the optical element
2Manufacturing precision
If the frame is customized for a specific smartphone model, then precise positioning and secure retention are achieved, but the headset cannot accommodate other phone sizes
Solution Approach 1:
The bumper system serves multiple functions: it provides precise positioning for different device types, offers secure retention through adjustable pressure, and enables compatibility across various smartphone models. The same mechanical structure adapts its configuration to serve different positioning requirements
3Device complexity
If fixed bumpers are used in the frame, then the structure is simple and robust, but the headset cannot accommodate smartphones of different sizes
Solution Approach 1:
The bumper system is divided into multiple independent movable bumpers rather than a single fixed structure. Each bumper can independently adjust its position and orientation, allowing the system to maintain relative simplicity while achieving adaptability through coordinated movement of segmented components
