Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bottle holders are expensive, require adhesives for assembly, and lack environmental sustainability, while also failing to provide effective insulation and versatility in holding various beverage containers.
Innovation Solution
A cardboard bottle holder designed as a single piece of corrugated cardboard with specific slots and folding mechanisms that can be easily assembled without adhesives, offering thermal insulation and the ability to hold multiple container types, featuring radiused edges and angled wings for secure bottle retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional materials like expanded polystyrene and neoprene are used for bottle holders, then thermal insulation is provided, but cost increases and environmental sustainability deteriorates
Solution Approach 1:
The patent changes the material parameter from traditional insulating materials (expanded polystyrene, neoprene) to corrugated cardboard, which provides adequate insulation while being cheaper and environmentally sustainable. The corrugated structure itself provides thermal insulation through air trapping in the flutes, eliminating the need for expensive synthetic insulating materials.
Solution Approach 2:
The patent uses corrugated cardboard as a composite material structure consisting of multiple layers with air pockets between the flutes. This composite structure provides thermal insulation equivalent to traditional materials while being made from renewable, biodegradable paper fibers, resolving the contradiction between insulation performance and environmental sustainability.
2Ease of manufacture
If bottle holders are made from multiple parts requiring adhesives, then assembly is possible, but manufacturing complexity and environmental friendliness worsen
Solution Approach 1:
The patent merges multiple parts (body, lid, insulation layers) into a single integrated corrugated cardboard structure. The interlocking flutes and slots allow all components to be formed from one piece of material without adhesives, eliminating assembly complexity while maintaining manufacturing ease through die-cutting and folding.
Solution Approach 2:
The patent segments the single corrugated cardboard piece into functional zones (body, lid, handles, insulation sections) that interlock through precisely engineered slots and flutes. This segmentation allows complex functionality to be achieved from a simple single-piece construction, avoiding the need for multiple separate parts and adhesives.
3Ease of manufacture
If a single piece of cardboard is used, then environmental friendliness and cost improve, but structural strength and insulation capability may worsen
Solution Approach 1:
The corrugated cardboard structure uses a composite design with outer liners and inner fluting that creates a strong, insulated structure. The flutes trap air for insulation while the layered construction provides structural strength, achieving both insulation and strength from a single material piece that is environmentally friendly and cost-effective.
Solution Approach 2:
The patent forms the corrugated cardboard into a cylindrical shape with curved surfaces that distribute mechanical stresses more effectively than flat structures. This curvature enhances the structural strength of the single-piece cardboard construction while maintaining the insulating air pockets within the corrugated structure.

Function Achieved in This Case
Provides an environmentally friendly, cost-effective solution with improved insulation and versatility in holding various beverage containers, allowing for high-resolution graphics and easy assembly, while eliminating the need for adhesives.
Implementation Method 1
They are made from a variety of materials such as expanded polystyrene and neoprene, that provide thermal insulation to a cold beverage on a hot day
Implementation Method 2
the folded wings are inserted into the cylindrical form where they are compressed against the body part by the insertion of a bottle, to capture the head as a base for the bottle holder

AI summary
One aspect of the invention provides a cardboard bottle holder able to be supplied flat and easily configured into a secure shape able to hold a variety of different bottles and cans. The bottle holder comprises a single piece of cardboard shaped to form a generally rectangular body part having: a first slot in a first side adjacent a first end, to define a tab extending along part of the first end; and a second slot in a second side opposite the first side, adjacent a second end opposite the first end, to define a tab extending along part of the second end in the opposite direction to the first tab. The lengths of the first and second slots are designed so that they can be engaged with each other to hold the generally rectangular part in a generally cylindrical form with the ends brought together to overlap each other.
