Wearable Device One-Handed Fastening via Open Groove and Hook
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable devices often require both hands to put on or take off, are inconvenient for users unfamiliar with one-handed operation, and are prone to falling and damage if not properly supported.
Innovation Solution
A wearable device design featuring a main body with a tail and hook portion, a band body that enters an open groove and is folded back around the hook, allowing for one-handed operation and secure fixation without the need for additional support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional wearable device fastening methods are used, then the device can be securely fixed to the body, but both hands are required to put on or take off the device, reducing ease of operation
Solution Approach 1:
The wearable device is divided into distinct functional components: a main body, a band body with tail portion, and a hook portion. This segmentation allows the band body to be independently manipulated and inserted through the opening, enabling one-handed operation while maintaining secure fixation.
Solution Approach 2:
Instead of traditional buckles or clasps that require two hands to manipulate, the design inverts the fastening mechanism by using a loop-and-hook system where the band body passes through an opening and secures to the hook portion. This inverted approach simplifies the fastening action to a single-handed motion of inserting and securing.
2Ease of operation
If the wearable device is worn without support or stabilization, then one-handed operation is enabled, but the device is prone to falling and damage
Solution Approach 1:
The band body is designed with a curved path that enters the opening and wraps around the hook portion, creating a loop configuration. This curvature provides mechanical advantage and stability, preventing the device from slipping or falling while allowing easy one-handed manipulation during the fastening process.
Solution Approach 2:
The wearable device structure allows the band body to automatically secure itself to the hook portion once inserted through the opening. The loop configuration and hook engagement create a self-locking mechanism that stabilizes the device without requiring additional support surfaces or two-handed operation, enabling the device to secure itself during one-handed wearing.
3Adaptability or versatility
If the band body is made adjustable to fit various body parts, then adaptability is improved, but the complexity of the fastening mechanism increases
Solution Approach 1:
The band body with its adjustable length and universal loop-and-hook fastening mechanism can be used on various body parts (wrists, ankles, necks) with different circumferences. The same simple fastening structure serves multiple functions and locations, achieving versatility without increasing mechanical complexity.
Solution Approach 2:
The band body length can be adjusted by selecting different attachment points along the band, allowing the same simple fastening mechanism to accommodate various body part sizes. This parameter adjustment (length selection) provides adaptability without adding complex adjustment mechanisms, maintaining simplicity while achieving versatility.

AI summary
A wearable device includes a main body and a band body. The opposite sides of the main body are provided with a tail portion and a hook portion, respectively. An open groove is provided between the hook portion and other parts of the main body. One end of the band body is connected to the tail portion. The band body enters the open groove from an open side of the open groove and is folded back around the hook portion. The other end of the band body is fixed to a part of the band body, so that the band body is coupled to the hook portion, and the band body is adapted to fix the main body to a subject.
