Telescoping Strap Assembly for Head-Mounted Display Fit Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional virtual reality headsets often suffer from poor fit issues due to their weight distribution, leading to discomfort and difficulty in achieving an immersive experience, especially when used by multiple users who need frequent refitting.
Innovation Solution
A telescoping assembly system for head-mounted display straps that includes a track, a boss element loosely coupled to the track, and a slide with a catch, allowing for adjustable strap length without removing the headset, providing discrete adjustment intervals and easy fitting for various head sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional headset straps are used with fixed length, then the structure is simple, but the fit is poor and requires frequent manual adjustment
Solution Approach 1:
The patent applies the dynamics principle by transforming the static fixed-length strap into a dynamic telescoping mechanism. The strap includes an extendable section with a slide that can move along a track, allowing the strap length to change dynamically. This enables the strap to adapt to different head sizes and fitting requirements while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent implements the nesting principle through the telescoping assembly where the slide with the catch mechanism nests within the track structure. The extendable section of the strap is contained within the telescoping assembly, allowing compact storage when not in use and easy deployment when adjustment is needed.
2Productivity
If multiple users share a headset, then resource utilization improves, but frequent refitting is required which reduces productivity
Solution Approach 1:
The dynamic telescoping mechanism allows each user to quickly adjust the strap length to their specific head size without requiring complete refitting. Users can simply extend or retract the strap to the appropriate length and secure it with the catch mechanism, significantly reducing adjustment time and enabling faster transitions between users.
3Adaptability or versatility
If the headset strap is made extendable with telescoping assembly, then adaptability to different head sizes improves, but the device complexity increases
Solution Approach 1:
The patent divides the strap into distinct segments: a fixed section, an extendable section within the telescoping assembly, and adjustment components. This segmentation allows the extendable functionality to be isolated to a specific portion of the strap, making the overall system more manageable and easier to manufacture despite the added adaptability.
Solution Approach 2:
The patent applies local quality by concentrating the complexity of the telescoping mechanism in a localized area rather than distributing it throughout the entire strap. The slide, track, and catch mechanism are confined to a specific section, allowing the rest of the strap to remain simple while providing the necessary adjustability where needed.

AI summary
A head-mounted-display adjustment apparatus may include a telescoping assembly. The telescoping assembly may include (1) a track, (2) a boss element that bears upon the track and that is loosely coupled to the track such that the boss element is liftable from the track by a limited distance, and (3) a slide that moves along the track, the slide including a catch that restrains the slide from moving along the track when the boss element bears upon the track. The adjustment apparatus may also include a strap with a distal section coupled to the head-mounted display and a proximal section coupled to the slide such that the strap is extendable, via movement of the slide, away from the head-mounted display.
