Foldable Nozzle with Cover Plate for Premature Pouring Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling of two-chamber containers for mixing and applying hair tinting solutions is cumbersome, as users often mix components without realizing they need to be applied immediately, leading to inefficient use and potential misuse by pouring the mixture without proper mixing.
Innovation Solution
A foldable nozzle with a cover plate and breaking line, made from flexible material, that requires pushing to unfold and mix components, reducing the risk of premature pouring by ensuring components are mixed before the nozzle is opened.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the nozzle body is made accessible for pulling from outside, then the nozzle can be easily unfolded, but the user may accidentally pull the nozzle without mixing the components first
Solution Approach 1:
The cover plate is designed to prevent the tip from being pulled out before the components are mixed. The cover plate must be removed first, which serves as a preliminary action that ensures the mixing step is completed before the nozzle can be unfolded and used for pouring.
Solution Approach 2:
The cover plate acts as an intermediary element between the user and the tip. It mediates the interaction by requiring the user to remove the cover plate before accessing the tip, thereby ensuring that the mixing process is completed first.
2Ease of operation
If the tip is made accessible from outside, then the nozzle can be unfolded by pulling, but the components may be poured without proper mixing
Solution Approach 1:
The cover plate prevents the tip from being pulled out before the components are mixed. The cover plate must be removed first, which serves as a preliminary action that ensures the mixing step is completed before the nozzle can be unfolded and used for pouring.
Solution Approach 2:
The cover plate, which might seem like an additional step complicating the process, actually converts the potential harm of premature pouring into a benefit by ensuring proper mixing occurs first. The extra step of removing the cover plate guarantees that the components are mixed before use.
3Volume of moving object
If the nozzle body is made from flexible material, then the nozzle can be folded compactly, but the structure becomes more complex
Solution Approach 1:
The nozzle body is designed with flexible material that allows it to change its shape dynamically between folded and unfolded states. The flexibility enables the nozzle to be compact when folded and functional when unfolded, adapting to different storage and usage requirements.
Solution Approach 2:
The nozzle body is constructed from flexible material that allows it to be folded into a compact form. The flexible shell structure enables the nozzle to maintain its integrity while being folded, and to unfold smoothly when needed for use.

AI summary
A nozzle for a two-chamber container for mixing two components and applying the mixture, comprises a foldable nozzle body, comprising a mainly ring-shaped connecting part for connecting the nozzle to a container body, wherein the connecting part is arranged at an outer diameter, a tip arranged mainly in the center of the nozzle body, the tip comprises a predetermined breaking line for providing an outlet in broken state, at least one intermediate folding ring connecting the tip with the connecting part so that the tip is movable relative to the connecting part in axial direction between a folded state, where the tip is arranged mainly radially inside the connecting part, and an unfolded state, where the tip is arranged mainly outside the connecting part, and a cover plate connected with the tip.
