Solution Overview

Problem

Existing chair-based phone holders fail to provide adjustable orientation for phone viewing, accommodate various device sizes, and maintain cleanliness, as they often accumulate debris and lack easy storage and washing options.

Innovation Solution

A rotatable cup holder integrated into a chair arm with upward projections and shoulders that allow for landscape or portrait viewing, easy cleaning, and storage, while accommodating different device sizes and beverage containers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed phone holder is integrated into the chair arm, then the phone can be held securely, but the viewing orientation cannot be adjusted to avoid glare or accommodate different formats

Engineering Contradiction:

Improvephone viewing convenienceVSAvoidviewing orientation adjustment

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The cup holder is designed to be rotatable within the cavity, transforming a static structure into a dynamic one. This allows the phone holder to adjust its orientation according to different viewing needs, resolving the contradiction between secure holding and orientation flexibility.

Inventive Principle:

Principle #15Dynamics

2Reliability

If a cup holder is molded into the chair arm, then beverages can be held securely, but the cavity accumulates dirt and debris when not in use

Engineering Contradiction:

Improvebeverage holding stabilityVSAvoiddebris accumulation in cavity

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The cup holder is designed as a removable component that can be taken out of the cavity when not in use. This extraction eliminates the harmful effect of debris accumulation in the cavity while preserving the secure beverage holding function when the cup holder is installed.

Inventive Principle:

Principle #2Taking out (Extraction)

3Strength

If a rigid phone holder is used, then the phone is securely supported, but it cannot accommodate devices of various sizes

Engineering Contradiction:

Improvephone support stabilityVSAvoiddevice size compatibility

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The phone holder uses a flexible projection that can adapt its shape and position locally to accommodate different device sizes. This localized flexibility within an otherwise stable structure allows secure support for various phone dimensions without compromising overall stability.

Inventive Principle:

Principle #3Local quality

AI summary

An assembly has a chair with at least one arm. The arm has a cavity formed therein. The cavity has a bottom and a side wall. A cup is removably received in the cavity. The cup has a bottom surface and an outer wall. The cup is rotatable within the cavity. The cup has at least one projection extending upwardly from a bottom surface of the cup. This projection is adapted to support a phone thereagainst. The cup is movable between a first position in which the projection is exposed outwardly of the chair, a second position in which the projection is stowed in the cavity and a third position in which the cup is positioned beneath the cavity.
