Solution Overview

Problem

Existing mobile device grip solutions lack versatility and convenience, particularly in providing an extendable and retractable mechanism that can serve as both a handheld grip and a stand, while maintaining a low profile for easy storage.

Innovation Solution

A device grip system comprising a device connecting assembly and a finger gripping assembly connected via jointed connection assemblies, which include channel joints and c-clamps, allowing for adjustable orientation and easy retraction to fit various applications, including car mounts and stands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a grip device is made extendable and retractable to serve multiple functions (handheld grip and stand), then versatility is improved, but device complexity increases

Engineering Contradiction:
ImproveversatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The grip device is divided into multiple segments including a base portion, an arm portion with joint assemblies, and a finger gripping portion. These segments can be extended or retracted independently through the joint assemblies, allowing the device to transform between a compact handheld grip configuration and an extended stand configuration, thereby achieving versatility without requiring completely separate devices

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The grip device incorporates dynamic joint assemblies that allow the arm portion to be adjusted between extended and retracted positions. These joints enable the device to change its configuration on-demand, transitioning from a compact form for portability to an extended form for stand functionality, resolving the contradiction between versatility and complexity through controlled dynamic transformation

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the grip device is extended to provide stand functionality, then adaptability is improved, but the profile size increases

Engineering Contradiction:
Improvestand functionalityVSAvoidprofile size
Core Design Contradiction:
Adaptability or versatilityVSLength of moving object

Solution Approach 1:

The finger gripping portion is designed to nest within or alongside the base portion when the device is in handheld grip mode. The joint assemblies allow the arm portion to fold back against the base, creating a compact nested configuration that minimizes profile size while maintaining all necessary components for both handheld and stand functionality

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If the grip device includes adjustable orientation features, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveadjustable orientationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The joint assemblies incorporate dynamic adjustment mechanisms that allow users to easily change the orientation of the arm portion between handheld and stand configurations. These joints provide smooth, controlled movement with minimal effort, enabling straightforward orientation adjustment without requiring complex locking mechanisms or multiple discrete components

Inventive Principle:
Principle #15Dynamics

AI summary

A system, method, and apparatus for securely gripping a mobile device can comprise a device connecting assembly comprising an upper base with an orifice formed therein, a bottom base, and a peg formed on the bottom base, a finger gripping assembly, and at least one jointed connection assembly connecting the device connecting assembly and the finger gripping assembly. A connective material can be formed on a bottom base. The finger side strut is configured to fold between two legs of the device side strut.
