Detachable Finger-Grip Securement for Tablet Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of personal, hand-held, tablet-shaped devices experience discomfort and fatigue due to the need to grip these devices for extended periods, leading to potential dropping and inadequate security during use, especially in settings without a stable surface.
Innovation Solution
A securement device featuring detachable finger-grip members with hook-and-loop coupling, attached to the back panel of the device, providing ergonomic support and adjustable apertures for comfortable holding, allowing users to securely hold the device without conscious gripping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user grips the device with their hand, then the device can be held securely, but the user experiences fatigue and discomfort over extended periods
Solution Approach 1:
The patent introduces finger grip members as an intermediary component between the user's fingers and the device body. These members provide a dedicated gripping interface that distributes pressure and reduces direct contact stress on the user's hand, thereby maintaining secure holding while improving comfort during extended use
Solution Approach 2:
The gripping function is segmented from the main device body through detachable finger grip members. This segmentation allows the gripping interface to be optimized independently for comfort, with features like apertures and contoured shapes that fit natural finger positions, while the device body remains lightweight and thin
2Weight of moving object
If the device is made thin and lightweight, then it is easier to carry and store, but the user may inadvertently drop it when not actively gripping
Solution Approach 1:
The finger grip members are pre-positioned on the device back panel at optimal locations for finger placement. This preliminary positioning ensures that when the user needs to hold the device, the gripping interface is already in place and properly oriented, enabling immediate secure grasping without requiring active adjustment or conscious gripping effort
Solution Approach 2:
The finger grip members act as an intermediary that enhances the effective gripping surface area and friction, compensating for the reduced weight and size of the device. This intermediary structure provides tactile feedback and mechanical engagement points that help prevent inadvertent dropping despite the device's lightweight construction
3Ease of operation
If a strap is provided along the spine of a book for hand support, then the book can be held easily, but this solution is impractical for tablet-shaped electronic devices
Solution Approach 1:
Instead of a continuous strap along the device edge, the patent uses segmented finger grip members with individual apertures positioned at specific locations on the back panel. This segmentation adapts the book-strap concept to the flat, tablet-shaped form factor by creating discrete contact points that accommodate finger insertion and provide localized support without requiring a longitudinal structure
Solution Approach 2:
Rather than supporting the device from the front or sides as with traditional book straps, the patent inverts the approach by providing gripping interfaces on the back panel of the device. This inversion allows the user's fingers to contact and support the device from behind, adapting the strap concept to the thin, tablet-shaped geometry where front and side access is limited
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 significantly reduces user fatigue, enhances the security of holding the device, and allows for easy mounting on surfaces, minimizing the risk of dropping and providing comfort during extended use.

AI summary
A securement device to make it much easier for a user to securely hold onto a personal, hand-held, tablet-shaped device such as an electronic reader, a tablet computing device, a cellular phone, a personal data assistant, and a common clipboard—while minimizing the fatigue and discomfort on the user's hands: A typical device solves this problem by providing a system of one or more finger holds formed with a fabric or pliable material that are disposed on the back side of the personal, hand-held, tablet-shaped device. In many devices, the position and fit of the finger holds are easily adjustable by a user via hook-and-loop schemes.
