Coffee Pot Spout Geometry for Leak-Proof Turkish Coffee Pouring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Turkish coffee machines, the existing designs face challenges in providing effective leak-proofing between the pouring spout and the cooking chamber ceiling, leading to potential overflow due to sharp edges damaging the sealing gasket and liquids escaping.
Innovation Solution
The coffee machine incorporates an arc-shaped surface on the pouring spout with a chamfer that extends beyond the gasket area, preventing sharp edge contact and ensuring leak-proofing, along with a groove to retain drops by surface tension and channels to catch dripping liquid, preventing it from reaching the outer surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pouring spout is positioned near the gasket to provide leak-proofing, then sealing effectiveness is improved, but the sharp edges of the pouring spout cut into the gasket and damage the sealing
Solution Approach 1:
The pouring spout is designed with a rounded tip instead of a sharp edge. This curved geometry allows the spout to contact the gasket without concentrating stress at a sharp point, thereby preventing cutting into the gasket material while maintaining effective sealing contact.
Solution Approach 2:
The spout geometry is modified locally at the tip region where contact with the gasket occurs. The rounded tip provides a localized area of distributed contact pressure, while the rest of the spout structure remains unchanged, allowing selective improvement of the sealing interface without redesigning the entire spout.
2Ease of operation
If the pouring spout extends out from the cooking pot to enable pouring, then pouring function is improved, but the spout contacts the ceiling of the cooking chamber instead of the gasket and leak-proofing is impaired
Solution Approach 1:
The spout is designed to extend in a specific spatial dimension away from the pot body, positioning the rounded tip to contact the gasket on the cooking chamber ceiling. This dimensional arrangement ensures that the spout reaches the sealing surface without the body of the spout interfering with the ceiling, maintaining both pouring functionality and sealing effectiveness.
3Reliability
If the cooking pot is lifted to provide leak-proofing pressure on the gasket, then sealing effectiveness is improved, but the pouring spout collides with the ceiling of the cooking chamber and damaging occurs
Solution Approach 1:
The rounded tip of the pouring spout allows it to make contact with the cooking chamber ceiling in a controlled manner during pot lifting. The curved geometry distributes the mechanical contact over a larger area and prevents sharp-point impact, thereby reducing damage to the ceiling while maintaining sealing pressure on the gasket.
Solution Approach 2:
The rounded tip design acts as a pre-designed cushioning element that softens the impact between the spout and ceiling during pot lifting. This geometric feature is built into the spout structure beforehand to prevent damage before it occurs, eliminating the need for additional protective mechanisms.
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
This design effectively prevents overflow and damage to the gasket, maintaining leak-proofing and ensuring that residual coffee drops remain on the spout or are caught by channels, preventing them from reaching the countertop.
Implementation Method 1
a groove is formed at the lower portion of the chamfer situated at the end of the pouring spout for the drops to retain suspended after the pouring process with the effect of surface tension, preventing running down
Implementation Method 2
channels are formed on the periphery of the pot at the vicinity of the base, encircling the outer surface for catching the downwards dripping drops, enabling the drops to cling with the effect of surface tension
