Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable cup sleeves often slip off due to imprecise fits and instability, leading to discomfort and potential spills, especially when holding hot beverages.
Innovation Solution
The development of fixable cup sleeves with temperature-independent adhesives, temperature-dependent adhesives, selective-surface adhesives, and friction increasers that securely attach to disposable cups, providing a stable and comfortable grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a cup sleeve is used to insulate the user from heat, then heat transfer to the hand is reduced, but the cup sleeve becomes unstable and may slip off the cup
Solution Approach 1:
The cup sleeve is divided into multiple functional layers: an insulating layer for heat reduction and a fixing layer with adhesive elements for stability. This segmentation allows each layer to perform its specific function optimally without compromising the other.
Solution Approach 2:
The patent combines the insulating function and the fixing function into a single integrated cup sleeve structure. The fixing elements are incorporated directly into the cup sleeve body, merging thermal protection and mechanical stability into one device.
2Adaptability or versatility
If an adjustable cup sleeve is used to fit various cup sizes, then versatility is improved, but the fit becomes imprecise and stability decreases
Solution Approach 1:
The cup sleeve incorporates adjustable components that allow dynamic adaptation to different cup sizes. The fixing elements can be positioned or activated as needed, enabling the same sleeve structure to securely fit various cup diameters while maintaining precise contact through the adhesive mechanism.
Solution Approach 2:
The patent utilizes changes in adhesive properties (temperature-dependent or pressure-activated) to maintain precise fit across different cup sizes. By changing the activation parameters of the fixing elements rather than the sleeve geometry, versatility is achieved without sacrificing fit precision.
3Reliability
If a cup sleeve is designed to be stable on the cup, then slippage is prevented, but the device complexity increases with additional fixing mechanisms
Solution Approach 1:
The cup sleeve employs a disposable design where simple, low-cost adhesive elements provide effective fixing. Rather than using complex reusable mechanical fastening systems, the patent utilizes single-use adhesive technology that achieves stable attachment without mechanical complexity.
Solution Approach 2:
The patent replaces complex mechanical fixing mechanisms (such as clips, straps, or buckles) with chemical adhesive systems. This substitution eliminates mechanical complexity while maintaining reliable anti-slippage performance through the adhesive bonding between the cup sleeve and cup surface.
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
The fixable cup sleeves effectively reduce heat transfer and prevent slippage by securely adhering to the cup, maintaining stability and comfort during use, even with varying cup sizes and temperatures.
Implementation Method 1
The adhesive element includes a tab having an adhesive capable of fixing the fixable cup sleeve to a disposable beverage cup
Implementation Method 2
The temperature-dependent adhesive may be formed over part or substantially all of interior surface 106 of the sleeve... the adhesive is generally non-adhesive at room temperature... but is generally adhesive at temperatures above about 100 degrees F.
Implementation Method 3
The friction increaser is capable of enabling the fixable cup sleeve to be fixed to the disposable beverage cup
Implementation Method 4
Often a cup sleeve is used to reduce the heat felt by a user by insulating the user from some of the heat on the holding surface of the cup

AI summary
This document describes fixable cup sleeves. One of these cup sleeves is selectively fixable to a cup using a temperature-dependent adhesive that is effective to fix the cup sleeve to a disposable beverage cup when the cup is holding a warm or hot beverage. Another of these cups sleeves includes a fixing element capable of holding the cup sleeve in a closed position and fixing the cup sleeve to a disposable beverage cup when opened.
