Cup sleeve structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cup sleeves do not provide an easy and environment-friendly solution for carrying hot and cold drinks, as they lack a handle, leading to the reliance on plastic bags and other non-environmentally friendly facilities.
Innovation Solution
A cup sleeve structure with a conical hollow-core body featuring first and second lateral faces, each equipped with straps that can be torn off and folded to form a handle, allowing users to grip and carry cup-shaped containers while reducing plastic bag usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cup sleeves are designed without handles to simplify structure and reduce material usage, then device complexity and material consumption are reduced, but ease of operation deteriorates as users cannot conveniently carry the containers
Solution Approach 1:
The cup sleeve is divided into functional segments: the main body for insulation and the integrated strap system for carrying. The straps are positioned on lateral faces and can be independently folded and connected to form handles, allowing the carrying function to be activated only when needed without complicating the basic sleeve structure
Solution Approach 2:
The carrying function is merged into the cup sleeve structure by integrating straps directly onto the lateral faces of the sleeve body. This combination eliminates the need for separate carrying devices while maintaining the simplicity of the basic sleeve design
2Ease of operation
If traditional plastic bags are used for carrying containers, then ease of operation is improved, but environmental harm increases due to non-biodegradable materials
Solution Approach 1:
The material composition parameter is changed from synthetic plastic to biodegradable paperboard, transforming the environmental properties while maintaining the carrying function. The paperboard material provides the necessary mechanical strength and environmental sustainability
3Temperature
If cup sleeves are made from thick materials to improve thermal insulation, then temperature protection is enhanced, but weight and material consumption increase
Solution Approach 1:
The cup sleeve utilizes composite paperboard structure with optimized layering and thickness distribution. The material composition and structural design provide effective thermal insulation while maintaining lightweight properties, avoiding the need for excessively thick single-layer materials
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
Enhances ease of use and reduces plastic bag dependency by enabling users to conveniently carry hot and cold drinks using a handle formed from the folded straps, while being made from environmentally friendly materials like bilayered or corrugated paperboard for thermal insulation and strength.
Implementation Method 1
the coffee shops, the convenience stores and drink shops provide thermo-insulated corrugated cup sleeves

AI summary
A cup sleeve structure for a cup-shaped container includes a body having a first lateral face and a second lateral face, the first lateral face having a first strap, the second lateral face having a second strap. Inner and outer edges of the first strap and the top end of the first strap each have a cutting line. The tail end of the first strap is connected to a first folding line. Inner and outer edges of the second strap and the top end of the second strap each have a cutting line. The tail end of the second strap is connected to a second folding line. When the first strap and second strap are torn off the first lateral face and second lateral face, respectively, and folded to be above the body. The first strap and second strap are connected by engagement to therefore form a handle.
