VR Headset Binding Band Adjusting Mechanism for Custom Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional VR devices have limited adjustability in their binding bands, which restricts their fit to different head sizes, making them less comfortable and less applicable to a wider range of users.
Innovation Solution
A binding band adjusting device with a supporting component, rotating component, triggering component, side binding bands, and front and back binding bands, where the rotating component adjusts the side binding bands' length and triggers the front and back binding bands' tension, allowing for customizable fit through two operating modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the side binding bands and front and back binding bands are made independent for adjustment, then the device complexity increases, but the adaptability to different head sizes improves
Solution Approach 1:
The patent combines the adjustment functions of side binding bands and front and back binding bands into a single integrated adjusting mechanism. The adjusting component can simultaneously control both types of binding bands through one operating interface, eliminating the need for separate adjustment mechanisms for each band, thus reducing device complexity while maintaining adaptability.
Solution Approach 2:
The adjusting component is designed with multi-functionality to perform both side binding band adjustment and front and back binding band adjustment through a single component. This universal adjusting mechanism can adapt to different head sizes and shapes by coordinating the movement of multiple binding bands simultaneously, achieving versatile fit without requiring multiple specialized components.
2Ease of operation
If only one type of binding band is adjustable, then the device complexity is reduced, but the ease of operation and user comfort deteriorate
Solution Approach 1:
The patent merges the adjustment operations for different binding bands into a single operational action. Users can adjust both side binding bands and front and back binding bands through one unified adjusting component, making the operation simpler and more intuitive compared to managing separate adjustment mechanisms for each band type.
Solution Approach 2:
The integrated adjusting mechanism automatically coordinates the movement of multiple binding bands based on user input. When the user operates the adjusting component, the system self-manages the complex coordination of different binding bands, eliminating the need for users to manually adjust each band separately and improving ease of operation.
3Adaptability or versatility
If multiple independent adjusting mechanisms are provided for different binding bands, then the adaptability improves, but the ease of manufacture deteriorates
Solution Approach 1:
The patent consolidates multiple independent adjusting mechanisms into a single integrated adjusting component. This unified component is designed to control both side binding bands and front and back binding bands, significantly simplifying the manufacturing process by reducing the number of separate parts, assembly steps, and quality control procedures while maintaining full adaptability.
Solution Approach 2:
The adjusting component is engineered as a universal mechanism that can accommodate and coordinate multiple binding bands. This multi-functional design allows a single component to perform the work of multiple specialized mechanisms, making the device easier to manufacture while preserving the ability to adapt to various head sizes and shapes.

AI summary
A binding band adjusting device and a head-mounted display device having the binding band adjusting device are provided. The binding band adjusting device includes a support assembly provided with a through hole, a rotating assembly matching the through hole, two side binding bands connected to the rotating assembly, a trigger assembly disposed on the support assembly and used for being triggered by the rotating assembly, and a front-back binding band that can fix with respect to the trigger assembly; when the rotating assembly rotates in different directions with respect to the through hole, the two side binding bands expand and contract with respect to the support assembly; when the rotating assembly moves in the axial direction of the through hole and triggers the trigger assembly, the trigger assembly loosens or clamps the front-back binding band.
