Solution Overview

Problem

Users face difficulties in manipulating mobile phones with one hand due to increased screen size and ergonomic challenges, leading to potential drops and safety hazards, especially during activities like driving or navigation.

Innovation Solution

A mobile phone holder featuring a flexible silica gel sheet with sliding units and adjustable chutes, allowing fingers to pass through and supporting the phone, made of polycarbonate with specific boss and hole configurations for secure one-handed use and adjustable height.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If mobile phone screen size is increased, then display quality and user interface are improved, but one-handed manipulation difficulty increases

Engineering Contradiction:
Improvescreen sizeVSAvoidone-handed manipulation
Core Design Contradiction:
Area of moving objectVSEase of operation

Solution Approach 1:

The patent introduces a holder as an intermediary device between the user and the mobile phone. The holder includes a base with a recess that receives the mobile phone, and a flexible sheet with sliding units that interact with chutes on the base. This intermediary structure provides mechanical support and control assistance, enabling users to easily manipulate large-screen phones with one hand while maintaining improved display quality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Duration of action of moving object

If mobile phone is held in hand for long time, then continuous usage is enabled, but user feels burden and may drop the phone

Engineering Contradiction:
Improvecontinuous usage timeVSAvoiduser comfort
Core Design Contradiction:
Duration of action of moving objectVSEase of operation

Solution Approach 1:

The patent transitions from pure hand-held usage to a hybrid support system by introducing a holder that rests on a surface (another dimension of support). The base with recess provides stable placement, while the flexible sheet with sliding units maintains phone security. This dimensional change allows the phone to be securely positioned without requiring continuous hand support, enabling longer usage duration with reduced user burden.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If mobile phone holder provides secure one-handed operation, then phone stability is improved, but device complexity increases

Engineering Contradiction:
Improvephone stabilityVSAvoidholder structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a flexible sheet as a thin film component that provides secure phone retention through its interaction with sliding units and chutes. The flexible sheet can deform to accommodate the phone while maintaining constraint through the sliding unit mechanism. This approach achieves reliable phone stability without requiring complex rigid structures, keeping the holder design relatively simple while ensuring secure one-handed operation.

Inventive Principle:
Principle #30Flexible shells and thin films

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

Enables easier one-handed operation and prevents phone drops, allowing users to free their hands while maintaining phone stability, especially during tasks that require both hands.

Implementation Method 1

a flexible sheet and a transparent adhesive sheet respectively mounted on the top surface and the bottom surface of the base

AI summary

The present invention relates to a mobile phone holder including a base, the holder: providing an extensible sheet and a sliding device so as to allow the fingers to pass through the arch-shaped extensible sheet during one-handed operations; making one-handed operations easier so as to prevent the mobile phone from dropping during one-handed operations; and allowing the height of the extensible sheet provided in an arch shape to be adjusted, thereby enabling the mobile phone to be put directly on a loading surface and allowing a user to freely use both hands.
