Bottle Opening Device with Replaceable Cutting Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle opening devices lack safety due to exposed cutting portions, are not adaptable to different bottle neck sizes, and require the entire device to be discarded if the cutting mechanism is damaged.
Innovation Solution
A bottle opening device with a shaft featuring a threaded portion and a widened portion with internally aligned openings, accommodating a supporting body with a cutting element that protrudes only during operation, allowing for safe and adjustable capsule cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cutting portion is exposed to enable capsule cutting, then the cutting function is accessible, but the user is exposed to the risk of cuts and wounds
Solution Approach 1:
A protective cover is introduced as an intermediary element between the user's hand and the cutting portion. The cover includes a through-hole that guides the cutting action while preventing direct contact with the sharp edge, thus mediating the interaction to maintain both accessibility and safety.
Solution Approach 2:
The protective cover acts as a thin film barrier that covers the cutting portion when not in use. This flexible or rigid thin structure provides continuous protection while allowing the cutting function to be accessed when needed through the designed opening mechanism.
2Device complexity
If the cutting portion is fixed and permanent to the device, then the structure is simple, but the entire device must be discarded if the cutting portion is damaged
Solution Approach 1:
The device is segmented into distinct components: the main body and the replaceable cutting portion. This segmentation allows the cutting portion to be separated from the device body, enabling replacement of only the damaged cutting element rather than discarding the entire device.
Solution Approach 2:
The cutting portion is designed with dynamic characteristics, allowing it to be attached and detached as needed. This dynamic design contrasts with fixed permanent attachments, providing flexibility for maintenance and replacement while maintaining operational simplicity.
3Stability of the object's composition
If the cutting portion is fixed in position, then the structure is stable, but the device cannot adapt to different sizes of bottle necks
Solution Approach 1:
The cutting portion is designed to be movable relative to the device body, allowing adjustment of its position. This dynamic capability enables the cutting element to be repositioned to accommodate different bottle neck diameters while maintaining stable cutting performance when positioned correctly.
Solution Approach 2:
The device achieves universality by combining a stable base structure with an adjustable cutting portion. This multi-functional design allows the same device to handle various bottle sizes and capsule types, making it adaptable to different applications while maintaining operational stability.

AI summary
Bottle opening device, particularly for cutting the capsule covering the stopper of a bottle, comprising a shaft provided with a threaded portion and, above, with a widened portion that has a hole in it.The widened portion comprises two plates which are provided internally with mutually aligned openings for the transversal insertion of a stopper.The plates are spaced apart so as to define a space for accommodating a supporting body which is provided with at least one cutting element.
