Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing cups with side handles are not suitable for use in vehicles due to the narrowness of typical cupholders and interference between the handle and the cupholder, limiting their usability in in-vehicle environments.

Innovation Solution

A cup with a rotatable handle that includes a position-limiting mechanism, allowing the handle to be adjusted to multiple positions, including upward and downward vertical directions, to accommodate different usage scenarios, such as traditional holding and in-vehicle insertion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed side handle is provided on the cup, then the cup is easy to hold and drink from in traditional settings, but the handle interferes with the narrow cupholder space in vehicles

Engineering Contradiction:

Improveease of holding and drinkingVSAvoidadaptability to in-vehicle environment

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The handle is designed to rotate relative to the cup body through a rotating connection mechanism, allowing it to dynamically change its position from a side extension to an upward orientation, thus adapting to different usage environments including vehicle cupholders

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The handle transitions from a two-dimensional side extension to a three-dimensional configuration by rotating upward, changing its spatial arrangement to fit within the vertical orientation required by vehicle cupholders

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the handle is made rotatable to fit in vehicle cupholders, then the cup becomes versatile for in-vehicle use, but the structural complexity increases due to the position-limiting mechanism

Engineering Contradiction:

Improveversatility for in-vehicle and traditional useVSAvoidcomplexity of position-limiting mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The position-limiting mechanism replaces complex mechanical locking systems with a simple magnetic field interaction, where a magnet in the shaft sleeve attracts a ferromagnetic component in the side shaft to automatically limit the handle to specific angular positions

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic attraction force parameter is utilized to create stable positional limits at specific angles, transforming the continuous rotation capability into discrete stable positions through magnetic field interaction rather than mechanical constraints

Inventive Principle:

Principle #35Parameter changes

AI summary

A cup with a rotating handle includes a cup body, a handle, the upper end of which rotates and is connected with the side of the cup body, and a limiting mechanism, wherein the handle and the cup body are connected. The limiting mechanism configured such that when the handle rotates upward to a first angular position, it is limited thereto, and when the handle rotates downward to a second angular position, it is also limited thereto, providing convenient adjustment of the direction of the handle.
