Detachable HMD Strap Interface With Latch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted displays often come with generic one-size-fits-all strap systems that may not fit users comfortably or aesthetically, and the straps can become worn and dirty, necessitating frequent replacement.
Innovation Solution
A detachable head-mounted-display strap interface system featuring a strap with electrical accessories and a mount that includes a mateable and demateable interface with a latch, allowing for easy attachment and detachment from the head-mounted display, providing secure electrical connections and adjustable fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a generic one-size-fits-all strap system is used, then the head-mounted display can be shipped with a standardized component, but the strap does not fit all users comfortably or aesthetically and cannot be easily replaced
Solution Approach 1:
The strap system is divided into separate modular components: a detachable strap portion and a mounting interface integrated with the head-mounted display. This segmentation allows users to remove and replace straps independently without replacing the entire head-mounted display unit, enabling customization while maintaining ease of replacement through simple detachment mechanisms.
2Ease of repair
If the strap system is made detachable with electrical connectors, then the strap can be easily replaced, but the device complexity increases due to additional electrical connection components
Solution Approach 1:
The electrical connectors are merged with the mounting interface structure itself, rather than being separate additional components. The electrical connection features are integrated into the existing mechanical mounting points, so that a single detachment action simultaneously breaks both the mechanical strap attachment and the electrical connection, simplifying the overall replacement process despite the presence of electrical components.
3Reliability
If the electrical connector is exposed on the mount, then electrical connection is achieved, but the connector may become damaged or disconnected during normal use
Solution Approach 1:
The electrical connector is nested within or recessed into the mounting interface structure, rather than being exposed on the exterior surface. This nesting protects the delicate electrical contact points from physical damage, contamination, and accidental disconnection during normal wear and handling, while still allowing for reliable electrical connection when the strap is properly attached.

AI summary
A detachable head-mounted-display strap-interface apparatus may include (1) a strap that includes an electrical accessory that necessitates an electrical connection to a head-mounted display and (2) a mount coupled to the strap that includes (a) an interface that is mateable and demateable to an opposing interface of the head-mounted display, (b) an electrical connector that is configured to provide the electrical connection from the electrical accessory to the head-mounted display when contacting an opposing electrical connector of the head-mounted display, and (c) a latch that couples, in a first orientation, the interface and the opposing interface of the head-mounted display and enables, in a second orientation, the interface to be decoupled from the opposing interface of the head-mounted display and the electrical connector to be disconnected from the opposing electrical connector. Various other detachable head-mounted-display strap-interface apparatus, devices, systems, and methods are also disclosed.
