Swappable Strap for Head-Mounted Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display systems face challenges in providing a secure and comfortable fit due to limitations in strap interchangeability and adjustability, which complicates manufacturing and user experience.
Innovation Solution
The integration of detachable strap systems with snap piece assemblies that can be easily attached and detached from side arms on the head-mounted display system, allowing for multiple strap types and configurations, facilitating secure and comfortable placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If detachable strap systems with snap piece assemblies are integrated, then strap interchangeability and ease of adjustment are improved, but device complexity increases
Solution Approach 1:
The strap system is divided into separate components: a detachable strap body and snap piece assemblies that attach to the head-mounted display. This segmentation allows the strap to be easily interchanged while keeping the main device simple. The snap pieces are separate modules that can be attached or removed without affecting the entire system.
Solution Approach 2:
The snap piece assemblies are designed as universal connectors that can work with multiple strap types and configurations. The same snap piece interface can accommodate different strap materials, widths, and styles, providing multi-functionality without increasing device complexity. This universal interface allows users to interchange straps while using the same attachment mechanism.
2Ease of operation
If multiple strap types and configurations are supported, then user comfort and fit are improved, but manufacturing complexity increases
Solution Approach 1:
By segmenting the strap system into modular components (detachable strap body and snap piece assemblies), the manufacturing process is simplified. Each component can be manufactured separately using standardized processes, then assembled. This avoids the need to manufacture multiple complete strap assemblies with different complexities.
Solution Approach 2:
The snap piece assemblies use standardized parameters and dimensions that remain consistent across different strap types. While strap materials, widths, and styles vary, the attachment interface parameters are standardized, allowing a single manufacturing process for the snap pieces to support multiple strap configurations.
3Ease of repair
If detachable snap piece assemblies are used, then ease of repair and maintenance are improved, but reliability of connection may worsen
Solution Approach 1:
The snap piece assemblies are pre-designed and pre-tested as modular units with built-in connection reliability. The snap fit mechanism is engineered with appropriate tolerance ranges and engagement forces to ensure reliable connection. This preliminary design and testing of the modular components ensures that ease of repair does not compromise connection reliability.
Solution Approach 2:
The detachable snap piece system enables users to perform their own repairs and maintenance by simply detaching and reattaching components. The self-service capability is built into the design through the user-friendly snap connection mechanism that requires no tools or specialized skills, while maintaining reliable connections through proper engineering of the snap fit.

AI summary
A head-mounted display (HMD) system may include a body having a right side and a left side, a display device coupled to the body and positioned to display content to a user when the HMD system is donned by the user, a right side arm coupled to the right side of the body and dimensioned such that, when coupled to a first portion of a swappable strap, the right side arm and the first portion of the strap form a first fastener, and a left side arm coupled to the left side of the body and dimensioned such that, when coupled to a second portion of the strap, the left side arm and the second portion of the strap form a second fastener. The first fastener and the second fastener may detachably secure the strap to the body of the HMD system. Various other methods and systems are also disclosed.
