Juicing head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing juicing machines often fail to efficiently extract juice from fruits due to insufficient pressure and juice retention, particularly near the fruit skin, leading to incomplete extraction and splashing.
Innovation Solution
A juicing head with increased radius and ribbing features is designed, where the ribs are arranged transverse to the motion direction, providing enhanced pressure and acting as a scraper to extract juice from the pulp while separating it from the skin, reducing splashing and facilitating juice direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the head transits through the recess with clearance, then the head can move freely, but juice extraction near the skin becomes incomplete
Solution Approach 1:
The head surface is equipped with ribs at specific locations (transverse to motion direction) that provide localized scraping action. These ribs create intimate contact with the recess walls at critical points where juice extraction is needed, while the overall head maintains clearance for movement. This local modification resolves the contradiction by enhancing extraction efficiency at specific zones without restricting head mobility.
2Device complexity
If the head presses the fruit with basic geometry, then the juicing process is simple, but juice retention near skin is insufficient
Solution Approach 1:
The ribs on the head surface perform preliminary scraping action during the head's transit through the recess. This preliminary action removes juice from the pulp near the skin before the main pressing operation, ensuring more complete extraction. The ribs are positioned to contact the recess walls at the beginning and end of the pressing cycle, preparing the fruit for more effective juice extraction.
3Productivity
If the head rotates on its own axis, then juicing action is enhanced, but the number of moving parts increases
Solution Approach 1:
The head performs multiple functions: it presses the fruit during its primary rotation around the male element axis, and simultaneously scrapes the recess walls through its transverse ribs. This multi-functionality eliminates the need for separate scraping mechanisms or additional rotational movements, maintaining device simplicity while enhancing juicing effectiveness. The same head structure that provides pressing action also performs scraping through the rib features.

Function Achieved in This Case
The ribbed juicing head optimizes juice extraction by ensuring snug contact with the recess walls, effectively separating pulp from skin and reducing juice loss, resulting in improved efficiency and cleanliness during the juicing process.
Implementation Method 1
the ribbing... acts as a scraper, helping to extract the juice that may be left in the pulp attached to the skin
Implementation Method 2
areas where the head radius has been increased to generate deformations or ribs that improve the juicing process

AI summary
Improved juicing head of the type with juicing heads present in juicing systems, where the fruit to juice is housed in a recess of a female element and is guided to meet the head of a male element that is temporarily inserted in the recess, pressing the fruit and extracting the juice, wherein the head comprises ribs on its surface, said ribs arranged transverse to the direction of motion of the head.
