V-Shaped Grip Structure for One-Handed Tablet Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for holding and handling small casings, such as input/display units, face challenges due to inadequate size adjustment, leading to poor control and increased fatigue, as they do not accommodate varying finger diameters and require constant hand positioning, which can result in accidental rotation and inefficient storage.
Innovation Solution
A device with a visible part in the shape of an uppercase 'V' featuring two oblique cylindrical rods that adjust to finger diameters, ensuring secure grip and preventing rotation, along with an invisible part for rotation and storage, allowing for adaptable use with both hands and reducing bulk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device uses a fixed-size vertical part to fit interdigital spaces, then the structure is simple, but it cannot accommodate varying finger diameters leading to poor control
Solution Approach 1:
The vertical part of the device is made flexible rather than rigid, allowing it to dynamically adapt to different finger diameters. The flexible material enables the vertical part to deform and conform to the specific dimensions of each user's fingers, providing a secure fit without requiring multiple size variants or complex adjustment mechanisms.
Solution Approach 2:
The device utilizes a flexible material whose physical parameters (elasticity, deformability) allow the vertical part to change its dimensions to match varying finger diameters. This parameter change capability enables a single device structure to serve multiple users with different hand sizes without compromising control precision.
2Adaptability or versatility
If the device uses segments to adjust vertical part length, then size adaptation is possible, but the adjustment is rough and not suitable for all fingers
Solution Approach 1:
Instead of discrete segment adjustments, the invention uses a continuously flexible vertical part that can change its effective length and shape smoothly. The flexible material allows continuous deformation to precisely match any finger diameter within the design range, eliminating the rough two-millimeter step adjustments of segmented designs.
Solution Approach 2:
The flexible vertical part can locally deform to match the specific contours and dimensions of different fingers. Each section of the vertical part can independently adapt to the local geometry of the fingers it contacts, providing precise fit for each user's unique hand anatomy.
3Ease of operation
If the device has a fixed interdigital space configuration, then the structure is simple, but it requires constant hand positioning changes causing fatigue
Solution Approach 1:
The flexible vertical part dynamically adapts to different hand positions and finger configurations. Users can naturally move their hands and fingers without concern for precise positioning, as the flexible device conforms to the actual finger arrangement, reducing fatigue and eliminating the need for conscious repositioning.
Solution Approach 2:
The flexible vertical part automatically adjusts itself to match the user's natural hand position and finger diameter. The device performs the adaptation function autonomously through material deformation, eliminating the need for users to consciously adjust their hand positioning or for manufacturers to provide multiple fixed-size variants.
4Reliability
If the device uses oblique rods in V-shape, then grip security is improved, but the device volume increases
Solution Approach 1:
The oblique rods forming the V-shape are integrated into and nested within the flexible vertical part. The rods are positioned such that they extend from the horizontal part and are enveloped by the flexible material, allowing the device to maintain the rotational prevention functionality of oblique rods while minimizing the overall volume increase through compact integration.
Solution Approach 2:
The invention merges the rigid oblique rod structure with the flexible vertical part into a unified design. The oblique rods and flexible material work together as an integrated system, where the rods provide structural support and rotational prevention while the flexible material provides adaptability, achieving both grip security and compact form factor.

AI summary
The invention relates to a device (1), having non-collinear rods, for picking up with one hand, either the left hand or the right hand, regardless of whether it is large or small, an input/display unit having one or two sections. It is made up, with regard to its part that is visible when it is in a (vertical) use position, of two oblique rods (4) that are fixed to the back (2) and around the sagittal plane (26) of the casing (3) in the case of a unit with one section, so as to make it possible to slide the fingers under these oblique rods (4) and to close up the fingers on either side of the base of the device (1), this having the effect of securing the casing (3) to the hand, therefore making it possible to hold and handle the casing effortlessly. The device according to the invention is particularly intended for tablets, e-readers and laptop computers.
