Upper Head Strap Module Sliding Base for Wearable Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Glasses-type head-mounted display devices often lack sufficient clamping force during intense movements, risking the device's stability and potential fall, especially when additional support is needed.
Innovation Solution
An upper head strap module with a sliding base, front buckle, and upper head strap that can be installed, removed, or replaced, utilizing a sliding rail with engaging parts for secure attachment and detachment, allowing for customizable sizing and appearance to fit individual head shapes and preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a glasses-type head-mounted display device is used, then the user can see three-dimensional images and experience immersive content, but the device lacks sufficient clamping force during intense movements and risks falling
Solution Approach 1:
The head strap system is divided into multiple independent components: side head straps connected to the temples and an upper head strap module that can be separately attached and adjusted. This segmentation allows each component to contribute to the overall clamping force and stability, with the upper module providing additional support during intense movements.
Solution Approach 2:
The upper head strap module incorporates a sliding base that can move along the temple, allowing dynamic adjustment of the strap position and tension. This dynamic mechanism enables the user to optimize the clamping force distribution according to different usage scenarios, providing enhanced stability during intense movements while maintaining comfort during normal use.
2Reliability
If an additional headband module is assembled to the temple end, then the clamping force is improved and device stability is enhanced, but the device structure becomes more complex
Solution Approach 1:
The upper head strap module is designed as a multi-functional component that serves multiple purposes: it provides additional clamping force, allows for size adjustment via the sliding mechanism, and can be attached or removed based on usage needs. This universality justifies the added structural complexity by delivering multiple benefits from a single modular addition.
Solution Approach 2:
The sliding base acts as an intermediary component between the temple and the upper head strap, facilitating easy attachment and detachment while maintaining a relatively simple overall structure. This intermediary mechanism reduces the complexity of direct integration by providing a standardized interface that simplifies the assembly process.
3Adaptability or versatility
If the upper head strap module is made customizable with different sizes and appearances, then user preference and fit are improved, but manufacturing complexity increases
Solution Approach 1:
The upper head strap module is segmented into standardized components (sliding base, front buckle, upper head strap) that can be manufactured independently using standardized processes. This segmentation allows for easier customization of individual components without requiring complete redesign of the entire module, thereby reducing manufacturing complexity while maintaining adaptability.
Solution Approach 2:
The module allows for parameter changes such as strap length and positioning through the sliding mechanism, enabling customization without requiring different manufacturing processes for each size variant. The standardized interface and adjustable mechanisms permit a single base design to accommodate multiple size requirements, simplifying manufacturing while enhancing adaptability.

AI summary
A wearable device includes a host, a side head strap module, and an upper head strap module. The host has a sliding rail. The side head strap module is connected to the host. The upper head strap module includes a sliding base, a front buckle, and an upper head strap. The sliding base is detachably coupled to the sliding rail and slides along the sliding rail. The sliding rail has a first engaging part. The sliding base has a second engaging part. An engagement between the first engaging part and the second engaging part temporarily fixes the sliding base to the sliding rail. The front buckle is pivotally connected to the sliding base. The upper head strap is connected between the side head strap module and the front buckle. In addition, an upper head strap module applied to the wearable device is also proposed.
