Tablet Grip Strap With Central Adhesive Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices fail to provide an ergonomic and secure way to hold electronic tablets, leading to discomfort and difficulty in maintaining balance, especially when using the device for extended periods or with one hand while interacting with the touch screen.
Innovation Solution
A gripping device featuring self-adhesive parts with flexible strips that distribute traction forces homogeneously, allowing for adjustable and removable attachment to the device, along with a loop for finger passage, enhancing user comfort and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hand strap is attached to a tablet to secure it to the user's hand, then the tablet is prevented from falling, but the device becomes cumbersome and difficult to apply
Solution Approach 1:
The securing device is divided into two separate self-adhesive parts that can be independently applied to the tablet, allowing for easy installation and removal while maintaining secure attachment
Solution Approach 2:
The self-adhesive parts enable the device to be easily applied and removed by the user without requiring additional tools or complex procedures, making the system self-servicing
2Ease of operation
If the connection is placed at the edge of the self-adhesive surface, then the flexible strip is easily accessible, but the tensile force creates stress concentration at the edges
Solution Approach 1:
The connection is positioned in a specific location on the self-adhesive part that optimizes both force distribution and flexibility, creating a localized solution that addresses both strength and accessibility requirements
Solution Approach 2:
The folded section of the flexible strip acts as a buffer zone that absorbs and distributes tensile forces before they reach the adhesive interface, preventing stress concentration and potential detachment
3Stability of the object's composition
If the user holds the tablet to one side to support its weight, then the tablet is stable, but muscle tension increases especially during long use
Solution Approach 1:
The self-adhesive securing device creates a duplicate support system that mimics the function of hand gripping, allowing the tablet to support itself and reducing the burden on user muscles during extended use
4Ease of operation
If the user places the tablet on the palm of an open hand, then balance is easier to maintain, but the tablet can easily slide out
Solution Approach 1:
The flexible strip connects the two self-adhesive parts to form an integrated loop structure that combines the advantages of both adhesive attachment and mechanical restraint, preventing the tablet from sliding out while maintaining ease of use
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 provides a comfortable, secure, and easy-to-use attachment method that reduces muscle tension and prevents the device from slipping, allowing for ergonomic handling and operation with one hand while freeing the other hand to interact with the screen.

AI summary
A fastening device (100) comprises a self-adhesive part (103) having a self-adhesive surface (104) and a connecting surface (105) which is situated on the opposite side from the self-adhesive surface (104). A flexible strip (119) extends from the connecting surface (105) of the self-adhesive part (103). The flexible strip (119) is joined to the self-adhesive part (103) by means of a connecting element (108) disposed in a region on the connecting surface (105). This region faces a central region of the self-adhesive surface (104). Thus, a traction force exerted on the flexible strip (119) is distributed substantially uniformly over the self-adhesive surface (104).
