Rotatable Hand Strap Integrating Grip and Stand for Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand straps and supports for portable electronic devices require users to own both and alternate between them, leading to laborious swaps and unnecessary space usage, as they lack a dual function for gripping and supporting.
Innovation Solution
A hand strap with a fastening, supporting, and gripping portion, featuring a rotatable and adjustable design that allows the device to be held and supported in various positions, including upright on a surface, using a central connecting element, supporting elements, and an elastic adjustable band.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users own both conventional hand strap and conventional support, then gripping and supporting functions are available, but device complexity and quantity of accessories increase
Solution Approach 1:
The patent combines a hand strap and a support structure into a single integrated accessory. The hand strap includes a fastening portion with connecting cords, a supporting portion with first and second supporting elements that can be deployed to form a stand, and a gripping portion with an elastic band. This merging eliminates the need for separate hand strap and support accessories, reducing the quantity of accessories while maintaining both gripping and supporting functions.
Solution Approach 2:
The hand strap is designed to perform multiple functions: it can be used as a gripping accessory when folded, and as a supporting stand when unfolded. The supporting elements can be deployed at different angles to support the device in various positions. This multi-functionality allows a single accessory to replace multiple specialized accessories, improving adaptability while reducing complexity.
2Reliability
If conventional hand strap and conventional support are used separately, then each performs its specific function well, but time is lost due to laborious swaps and space is wasted for keeping the one not in use
Solution Approach 1:
By integrating the hand strap and support functions into one accessory, the patent eliminates the need to swap between separate items. The supporting elements are folded within the hand strap structure and can be quickly deployed or stowed without removing the accessory from the device, saving time while maintaining reliable gripping and supporting performance.
Solution Approach 2:
The supporting elements are designed to be dynamically deployable and foldable, allowing quick transitions between gripping and supporting modes. The first and second supporting elements can be rotated and positioned at different angles, and the elastic gripping portion can be adjusted, enabling rapid adaptation between functions without time-consuming swaps.
3Adaptability or versatility
If hand strap is designed with additional supporting structure, then supporting function is added, but device complexity increases
Solution Approach 1:
The supporting elements are nested within the hand strap structure when not in use. The first and second supporting elements are folded inside the fastening portion and gripping portion, creating a compact integrated design. This nesting approach adds the supporting function while minimizing the increase in overall structural complexity and maintaining a sleek appearance.
Solution Approach 2:
The hand strap uses flexible materials and thin structural elements that can be easily folded and stored. The elastic adjustable band and flexible supporting elements allow the structure to adapt to different configurations without requiring complex mechanisms, adding functionality while keeping the design simple and lightweight.
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
Enables convenient gripping and simultaneous support of portable electronic devices, reducing the need for multiple accessories and allowing quick transitions between holding and standing positions.
Implementation Method 1
The gripping portion has an elastic adjustable band and a ring. After penetrating the ring, the elastic adjustable band is divided into a first portion and a second portion. The ring adjusts the lengths of the first portion and the second portion.
Implementation Method 2
The second supporting element is rotatably pivotally connected to the fastening portion about an axis perpendicular to the rear surface.

AI summary
A hand strap for a portable electronic device is disclosed, wherein the hand strap comprises a fastened portion, a supporting portion and a holding portion. The fastened portion is fixed on a rear surface of the portable electronic device. The supporting portion has a first support body and a second support body. The second support body is rotatable to pivot on the fastened portion in accordance with an axis which is perpendicular to the rear surface of the portable electronic device. In a folded state, the first support body and the second support body are attached to each other. In an extended state, the first support body is inclined an angle corresponding to the second support body so as to support the portable electronic device.
