Flexible Adjusting Clip for Head-Mounted Display Strap Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted display devices suffer from loose upper head bands due to insufficient binding force from hook and loop fasteners, making adjustments difficult while wearing and leading to instability.
Innovation Solution
A wearable part with a flexible adjusting clip that includes an extension housing, guiding units, and an adjusting button, allowing for easy adjustment of the upper head band length without removing the device, and ensuring secure fastening to prevent loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hook and loop fastener is used to adjust upper strap length, then adjustability is improved, but binding force is insufficient causing the fastener to tear off easily
Solution Approach 1:
The upper strap is divided into multiple segments with corresponding hook structures and loop structures at different positions. The adjusting mechanism includes a moving component that can selectively engage with different segments, allowing the strap to be adjusted in length while maintaining secure binding at each position through the segmented fastening system.
Solution Approach 2:
The fastening system transitions from a static hook-and-loop connection to a dynamic adjusting mechanism. The moving component can shift position along the upper strap to engage with different hook-loop pairs, enabling length adjustment while maintaining reliable binding through the dynamic repositioning capability.
2Adaptability or versatility
If hook and loop fastener is used for upper strap adjustment, then length adaptability is improved, but ease of operation deteriorates as adjustment requires removing the device
Solution Approach 1:
The adjusting mechanism incorporates a moving component that can be repositioned along the upper strap while the device is worn. This dynamic repositioning capability allows users to adjust the strap length conveniently without removing the head-mounted display device, as the moving component can engage with different hook-loop segments in place.
Solution Approach 2:
The adjusting mechanism is designed to be self-adjusting through the moving component that can be easily repositioned and engaged with different hook-loop pairs. The system serves itself by allowing the user to modify the upper strap length independently while wearing the device, without requiring external assistance or device removal.
3Device complexity
If conventional upper strap design is used, then device simplicity is maintained, but stability deteriorates as the upper strap becomes loose
Solution Approach 1:
The upper strap is segmented into multiple sections with distributed hook structures and loop structures. This segmentation allows for multiple binding positions and enhances overall fastening stability, as the moving component can engage with different segments to prevent loosening while maintaining a relatively simple overall strap design.
Solution Approach 2:
The fastening system becomes dynamic with the moving component that can reposition along the upper strap to maintain optimal binding tension. This dynamic adjustment capability prevents the strap from becoming loose over time, enhancing stability without requiring complex rigid structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for convenient and stable adjustment of the upper head band length, preventing loosening and enhancing the overall stability and comfort of the head-mounted display device.
Implementation Method 1
an elastic element received in the receiving space, one end of the adjusting button abutting against the elastic element, the other end of the adjusting button abutting against the fastening portion, so the upper head band being clamped between the fastening portion and the wall of the penetrating groove

AI summary
A head-mounted display device includes a wearable part and a display part. The wearable part includes a main body, an upper head band, two side head bands, and a flexible adjusting clip mounted on the main body. One end of the upper head band has a beginning end fastened with a top of the display part, and the other end of the upper head band has a terminal end fastened with a top of the main body. Two ends of the two side head bands are connected with two sides of the main body. The flexible adjusting clip includes an extension housing, a penetrating groove, an adjusting button having two guiding rods, and two elastic elements. The two elastic elements are worn around the two guiding rods. The other two ends of the two side head bands are connected with two sides of the display part.
