Grip Apparatus for Portable Devices with Sliding Finger Band
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable devices with large screens and slim bar shapes are difficult to grip, leading to a risk of dropping and high repair costs due to damage from drops.
Innovation Solution
A grip apparatus featuring a base unit with a sliding hole, independently movable sliders, and a band unit that forms a finger-insertable space when the sliders are moved, with protrusion and support features to stabilize the device and reduce resistance.

Engineering Contradiction Analysis
1Shape
If a portable device has a large screen and slim bar shape, then the device becomes more modern and aesthetically pleasing, but the device becomes difficult to grip and prone to dropping
Solution Approach 1:
The patent applies dynamics by making the band unit flexible and deformable, allowing it to adapt to different finger sizes and gripping positions. The band unit can be deformed to form a space for finger insertion, and the sliders can move along the sliding hole to adjust the grip configuration dynamically, thereby maintaining grip stability on slim bar-shaped devices.
Solution Approach 2:
The band unit is implemented as a flexible component that can be deformed to form a space for finger insertion. This flexible structure allows the grip apparatus to adapt to the slim bar shape of portable devices while providing stable grip, resolving the contradiction between the device's slender form factor and grip stability.
2Reliability
If the band unit is deformed to form a finger-insertable space, then grip stability is improved, but the structural complexity increases
Solution Approach 1:
The grip apparatus is segmented into distinct functional components: a base unit, a sliding hole, a pair of sliders, and a band unit. This segmentation allows each component to perform its specific function independently, simplifying the overall structure while achieving grip stability through the coordinated action of these modular elements.
Solution Approach 2:
The sliders act as intermediary elements between the base unit and the band unit. They move along the sliding hole to adjust the band unit's configuration, providing a mechanical linkage that transforms simple linear motion into the complex deformation needed to form the finger-insertable space, thereby reducing overall structural complexity.
3Reliability
If protrusion portions are added to maintain slider position, then grip stability is improved, but manufacturing complexity increases
Solution Approach 1:
The protrusion portions are merged with the sliding hole structure, forming an integrated component rather than separate parts. This combining of features allows the sliding hole to simultaneously guide slider movement and maintain slider position through the protrusion portions, simplifying the manufacturing process while ensuring stable slider positioning.

AI summary
Provided is a grip apparatus for a portable device. The grip apparatus includes a base unit mounted on the portable device, a sliding hole formed in the base unit in a longitudinal direction of the base unit, a pair of sliders inserted into the sliding hole and independently movable along the sliding hole, and a band unit coupled to the pair of sliders and deformed to form a space, into which a finger is insertable, as at least one of the pair of sliders is moved.
