Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional virtual reality headsets often have sub-optimal fitting processes, making it time-consuming and difficult for users to achieve a comfortable and secure fit, disrupting immersive experiences.
Innovation Solution
An adjustable head-mounted-display strap assembly with an axial strap and top strap, featuring an adjustable attachment mechanism that allows for customizable overlap and connection points, enabling quick and easy adjustments to fit various head sizes, using mechanisms like hook and loop fasteners, snap fasteners, or strap adjusters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional headsets provide fixed fitting options, then manufacturing complexity is reduced, but adaptability to different head sizes deteriorates
Solution Approach 1:
The axial strap is divided into multiple sections (first axial section, second axial section, third axial section) that can be independently adjusted and connected. This segmentation allows each section to be optimized for different head sizes while maintaining overall adaptability without requiring complete redesign of the entire strap assembly.
Solution Approach 2:
The strap assembly incorporates adjustable attachment mechanisms with movable components (such as adjustable attachment points and flexible connections) that allow dynamic reconfiguration. Users can adjust the position and configuration of strap sections to match different head circumferences, transforming a static structure into a dynamically adaptable one.
2Ease of operation
If traditional headsets require manual adjustments over several fitting attempts, then adaptability is improved, but time consumption increases
Solution Approach 1:
The strap assembly is pre-configured with multiple attachment points and adjustable sections positioned at optimal locations before use. This preliminary arrangement of adjustment mechanisms allows users to quickly find the correct fit by simply selecting and securing at the appropriate pre-positioned points, eliminating the need for multiple iterative adjustments.
Solution Approach 2:
Adjustable attachment mechanisms serve as intermediaries between the fixed headset structure and the variable user head dimensions. These mechanisms (including movable connectors and adjustable fasteners) mediate the fitting process by providing a simple interface that translates user needs into quick structural adjustments without requiring complex manual manipulation.
3Manufacturing precision
If traditional headsets use fixed strap configurations, then device complexity is reduced, but fitting precision deteriorates
Solution Approach 1:
Different sections of the axial strap are designed with locally optimized properties - the first axial section may have different adjustment capabilities, material properties, or connection mechanisms compared to the second and third sections. This local differentiation allows each part to contribute specifically to achieving precise fitting without requiring the entire strap assembly to be complex.

AI summary
The disclosed strap assembly may include an axial strap, connected to a head-mounted display, configured to be worn around the circumference of a user's head in a manner that holds the head-mounted display against the user's face. The axial strap may include a left axial section and a right axial section. The strap assembly may also include an adjustable attachment mechanism configured to removably attach the right axial section to the left axial section at the back of the user's head. Additionally, the strap assembly may include a top strap, configured to be worn along the top of the user's head. The top strap may include (1) a ventral end coupled to a medial section of the head-mounted display and (2) a dorsal end that splits into a left dorsal end and a right dorsal end, each of which couples to the axial strap.
