Solution Overview

Problem

Existing grip devices for portable electronic devices are inconvenient to operate and do not provide stable and comfortable holding.

Innovation Solution

A grip device comprising a base, first and second members, a plate, and a grip with finger holes, where the members and plate components are designed to slide, pivot, and rotate to facilitate stable and comfortable grip through various mechanical interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a simple loop portion is used for gripping, then the device structure is simple, but the gripping stability and comfort are insufficient

Engineering Contradiction:
Improvegripping comfortVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The grip device is divided into multiple functional segments: a base portion attached to the electronic device, a plate portion with locking mechanism, and a grip portion with finger holes. These segments are connected through sliding and pivoting interfaces, allowing each to perform its specific function while contributing to overall gripping stability and comfort.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The grip device incorporates dynamic elements including a plate that slides back and forth relative to the base, and a grip portion that rotates relative to the plate. These dynamic capabilities allow the device to adapt to different gripping positions and angles, enhancing comfort while maintaining structural integrity through controlled motion ranges.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If a sliding plate with locking mechanism is added, then the gripping stability is improved, but the operation convenience deteriorates

Engineering Contradiction:
Improvegripping stabilityVSAvoidoperation convenience
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The locking mechanism is designed to engage and disengage automatically through the sliding motion of the plate. When the plate slides to a specific position, the locking protrusion on the plate naturally aligns with and engages the locking hole, providing self-locking functionality that maintains gripping stability without requiring additional manual operations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The plate acts as an intermediary element between the base and the grip portion. It provides a sliding connection that allows controlled movement while the locking mechanism ensures stable positioning. This intermediary structure mediates between the need for stability and the need for operational flexibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If multiple members with sliding and pivoting capabilities are incorporated, then the gripping comfort is enhanced, but the device complexity increases

Engineering Contradiction:
Improvegripping comfortVSAvoidmechanical interaction complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The grip device combines multiple functional elements into an integrated structure: the base portion, plate portion, and grip portion are merged through sliding and pivoting connections. This merging allows the device to provide multi-degree-of-freedom adjustment capabilities while maintaining a compact and unified overall structure that does not excessively increase complexity.

Inventive Principle:
Principle #5Merging (Combining)
