Plastic Bottle Zigzag Groove Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic bottles for beverages lack a secure and convenient means of attachment to clothing or bags, leading to poor reliability and increased manufacturing complexity, as well as high loads on attachment brackets.
Innovation Solution
A plastic bottle design featuring a hollow thin-walled body with an open groove molded parallel to the central axis, where the groove walls are configured with zigzag-shaped projections to increase the contact area and friction factor, allowing secure attachment to clothing or bags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate holder is manufactured and mounted on the bottle, then the bottle can be carried in hands, but the cost of the bottle increases
Solution Approach 1:
The holder is merged with the bottle body by molding it as an integral part of the bottle during the same manufacturing process. This eliminates the need for separate production and assembly of the holder, reducing manufacturing complexity while maintaining the carrying function.
Solution Approach 2:
The bottle body serves dual functions: containing the beverage and providing a carrying holder through the molded groove structure. This multi-functionality eliminates the need for separate carrying accessories, reducing overall device complexity.
2Ease of operation
If an integral bracket is molded in the bottle body, then the holder can be attached to clothing, but the manufacturing complexity increases
Solution Approach 1:
The holder groove is merged with the bottle body structure and molded simultaneously in a single manufacturing process. This integration approach maintains attachment capability while avoiding the complexities of multi-step manufacturing or assembly processes.
3Ease of manufacture
If a smooth groove is molded in the bottle, then the manufacturing is simple, but the attachment reliability to clothing is poor
Solution Approach 1:
The groove surface is given a localized zigzag profile specifically at the contact regions where the bottle attaches to clothing. This local modification increases friction and attachment reliability without complicating the overall manufacturing process, as the zigzag pattern can be easily incorporated into the molding tool.
Solution Approach 2:
The zigzag groove profile introduces curved and angled surfaces instead of a smooth linear groove. These curved surfaces increase the mechanical interlocking and friction between the bottle holder and clothing material, improving attachment reliability while remaining manufacturable through standard molding techniques.
4Ease of operation
If the holder is designed as an open groove parallel to the central axis, then the bottle can be attached to clothing, but the friction factor is low resulting in poor attachment reliability
Solution Approach 1:
The groove is given a zigzag cross-sectional profile with increased surface area and irregular geometry at the contact points. This local surface modification significantly increases the friction factor between the holder and clothing, improving attachment reliability while maintaining the simple open groove structure for ease of operation.
Solution Approach 2:
The zigzag profile introduces multiple curved surfaces and angles within the groove structure. These curved surfaces increase mechanical interlocking and friction with the clothing material, enhancing attachment reliability without compromising the simplicity of the holder design or its ease of operation.
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 design enhances the reliability of attachment by increasing the friction factor, making it easier to carry the bottle securely on clothing or bags without additional manufacturing costs or complexity.
Implementation Method 1
the area of contact between the bottle and the object of attachment is increased, and the material, to which the bottle is attached, is bent, which enables to increase the friction factor

AI summary
The invention relates to the storage and transportation of liquid products, and specifically to a plastic bottle. The challenge which this invention is designed to address is to increase the performance characteristics of a bottle, i.e. to create a lightweight design of bottle which is easy to manufacture and enables said bottle to be securely attached to items of clothing etc. The challenge in question is addressed by the fact that the plastic bottle, comprising a hollow thin-walled body ending with a neck, and a holder which is designed in the form of an open groove, molded in the body, parallel to the central axis of the bottle and extending for more than half the height of the bottle, is characterized by the fact that the projections of the walls of the groove on the plane, which is perpendicular to the transverse axis of the groove, are in the form of zigzag-shaped lines. Furthermore, each zigzag-shaped line may consist of sections of straightlines and/or sections of curved lines.
