Flexible Strap Smartphone Grip with Movable Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smartphone holders, such as straps and rings, are inconvenient due to their large size, difficulty in preventing smartphones from sliding, and complex structures that increase weight and volume, making them less portable and economically inefficient.
Innovation Solution
A flexible strap with a supporting plate that allows one finger to be inserted between the strap and the plate, which moves along the strap, providing a restoring force to maintain the plate's position and increase friction, allowing for various holding types and improved portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a finger ring type holder is used to prevent drop accidents, then holding ability is improved, but only one finger can be inserted causing fatigue accumulation
Solution Approach 1:
The supporting plate is divided into an upper part and a lower part that can be folded relative to each other, allowing multiple fingers to be inserted and distributed across different segments of the plate, thereby preventing fatigue accumulation on a single finger while maintaining holding ability
2Volume of moving object
If a hinge is applied to the ring to minimize volume when keeping, then portability is improved, but structure becomes complicated and volume and weight are increased
Solution Approach 1:
The supporting plate is designed with a folding mechanism that allows dynamic transformation between a flat stored state (minimizing volume) and a functional three-dimensional state during use, enabling the plate to adapt its shape based on whether it is being carried or utilized
3Reliability
If strap products are used to hold smart phones, then holding function is provided, but excessive force is required causing inconvenience
Solution Approach 1:
The supporting plate acts as an intermediary element between the user's hand and the smartphone, distributing the holding force across multiple contact points (fingers and plate surface) rather than requiring concentrated force, thereby reducing the effort needed while maintaining secure holding
4Ease of manufacture
If smart ring or pop socket products are used with fixed positions, then installation is simplified, but difficulty to use for long period due to close contact with rear surface
Solution Approach 1:
The supporting plate can be positioned at different locations along the strap through the penetration hole, allowing users to adjust the plate's position to suit different usage scenarios and durations, thereby maintaining comfort and effectiveness over extended periods
