Solution Overview

Problem

Existing drinking vessels designed for people with disabilities may be unsuitable for others and are difficult to clean, as they require specific head and tongue movements, and are easily recognizable as assistive devices.

Innovation Solution

A drinking vessel with a magnetic holder embedded in the wall to securely hold a drinking straw in place, allowing easy use by people with or without disabilities, and featuring a design that hides the magnetic holder for aesthetic appeal and ease of cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a spout attachment is integrated into the vessel, then people with physical and/or mental disabilities can use the vessel more easily, but the vessel becomes immediately recognizable as an assistive device and is more difficult to clean

Engineering Contradiction:
Improveease of use for people with disabilitiesVSAvoidcleaning difficulty and aesthetic appearance
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention extracts the functional elements (magnetic holder and straw) from the traditional spout attachment design. Instead of integrating a physical spout structure into the vessel rim, the solution uses a magnetic holder embedded in the vessel wall to secure a separate drinking straw, thereby eliminating the need for complex spout attachments while maintaining ease of use for people with disabilities

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The magnetic holder serves multiple functions: it secures the drinking straw in place, allows for easy cleaning by being embedded flush with the vessel surface, and can be designed to be aesthetically pleasing rather than obviously assistive. This multi-functional approach replaces the single-function spout attachment

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If the magnetic holder is embedded flush with the inside surface, then cleaning is easier and the vessel maintains aesthetic appearance, but the straw may not be held as securely

Engineering Contradiction:
Improvecleaning ease and aesthetic appearanceVSAvoidstraw holding security
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The magnetic holder is pre-embedded in the vessel wall during manufacturing, creating a secure mounting position before the straw is inserted. This preliminary action ensures both the aesthetic flush appearance and provides a reliable magnetic attachment point for the straw

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The magnetic holder is constructed using composite materials or a magnetic element enclosed in a non-magnetic housing that can be embedded flush with the vessel wall. This allows the magnetic function to be hidden while maintaining secure holding capability through the magnetic field generated by the embedded magnetic element

Inventive Principle:
Principle #40Composite materials

3Ease of operation

If the magnetic holder protrudes from the outside of the vessel wall, then it is visible and facilitates positioning of the straw, but it impedes cleaning and affects aesthetic appearance

Engineering Contradiction:
Improvestraw positioning visibilityVSAvoidcleaning difficulty and aesthetic appearance
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The magnetic holder is embedded flush with the inner surface of the vessel wall, creating a local quality difference where the magnetic function is accessible from the inside while the outer surface remains smooth and aesthetically pleasing. This localized embedding allows cleaning to proceed without obstruction while maintaining visual appeal

Inventive Principle:
Principle #3Local quality

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

AI summary

A drinking vessel (1) has a magnetic holder (10) embedded in a vessel wall (2) of the drinking vessel (1). The magnetic holder (10) is designed to exert an attractive force on a drinking straw (12) and to hold the drinking straw (12) in a fixed position against an inner surface of the vessel wall (2). This prevents the drinking straw (12) from moving uncontrollably during use when a person brings the drinking vessel (1) with the drinking straw (12) to their mouth.
