Solution Overview
Problem
Existing head-mounted displays suffer from discomfort, poor fit, and light leakage due to mismatched interfacing structures and positioning systems, which compromise the immersive experience, especially during prolonged use.
Innovation Solution
A head-mounted display system with a resilient and adjustable positioning and stabilizing structure, featuring a rear support hoop, forehead support, and extensible connectors, along with an adaptable interfacing structure that includes silicone and textile materials for improved comfort and light sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed positioning structure is used, then the display unit can be held in position, but it causes discomfort and poor fit for users with various head sizes and shapes
Solution Approach 1:
The positioning structure incorporates adjustable components including a ratchet mechanism and telescopic arms that allow dynamic adjustment to accommodate different head sizes and shapes, transforming a static structure into an adaptable one that maintains comfort across diverse users
Solution Approach 2:
The system enables parameter changes by allowing adjustment of the positioning structure's dimensions and configuration through mechanisms like the ratchet system and telescopic arms, permitting customization for various head geometries while maintaining structural integrity
2Adaptability or versatility
If an adjustable positioning structure is added, then fit for various head sizes is improved, but the device complexity increases
Solution Approach 1:
The positioning structure is divided into modular segments including telescopic arms, adjustable bands, and ratchet mechanisms that can be independently adjusted, allowing complex adaptability to be achieved through coordinated simple components rather than a monolithic complex structure
Solution Approach 2:
The adjustment mechanisms serve multiple functions simultaneously - the ratchet system provides both positioning and locking functions, while the telescopic arms provide both length adjustment and angular adjustment, reducing the need for separate dedicated components for each adjustment type
3Stability of the object's composition
If the display unit is held firmly to prevent movement, then positioning stability is improved, but light leakage occurs at the interfacing edges
Solution Approach 1:
The interfacing structure incorporates flexible light-blocking material that can conform to the contours of the user's face, creating an effective light seal without requiring excessive clamping force that would cause discomfort or compromise positioning stability
4Weight of moving object
If the head-mounted display is made lightweight, then wearability is improved, but the positioning and stabilizing structure becomes insufficient
Solution Approach 1:
The positioning structure utilizes flexible yet strong material that provides adequate stabilizing force without requiring excessive mass, allowing the display to remain lightweight while maintaining positioning stability through the material's inherent mechanical properties rather than relying on weight
