Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fruit presses are cumbersome to handle due to the multi-part structure and the need to remove the sieve insert and collection cup for juice extraction, leading to inefficient juice removal and handling difficulties.
Innovation Solution
A hand-operated fruit press design where the sieve and support bracket are directly connected to the first lever arm, allowing the collection cup to be easily detached and handled separately, enabling juice to drip directly into a glass or bowl, and the press body is integrated into the lever arm for a compact, easy-to-clean design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the sieve insert and support bracket are integrated into a multi-part structure with multiple joints, then the fruit press can be disassembled for cleaning, but the device becomes expensive to manufacture and cumbersome to handle
Solution Approach 1:
The patent integrates the sieve insert and support bracket into a single integrated component that is directly connected to the first lever arm. This merging eliminates the need for multiple separate parts and joints, reducing manufacturing complexity and cost while maintaining ease of cleaning through the integrated design.
2Productivity
If the sieve insert is separately positioned in the container, then it can be removed for cleaning, but the juice removal process becomes cumbersome and time-consuming
Solution Approach 1:
The sieve insert and support bracket are merged into a single integrated component connected to the first lever arm, allowing the entire assembly to move together during pressing. This eliminates the need to separately remove and handle the sieve insert, significantly improving juice removal efficiency and reducing operational complexity.
Solution Approach 2:
The integrated sieve insert and support bracket are positioned and secured to the first lever arm before the pressing operation begins. This preliminary integration ensures that no additional manipulation is needed during or after pressing to access or remove the sieve, streamlining the juice extraction process.
3Ease of operation
If the collection cup is permanently attached to the juicer, then juice collection is convenient, but the juicer becomes unwieldy and difficult to handle for small juice requirements
Solution Approach 1:
The collection cup is designed as a detachable component that can be separated from the juicer body. This segmentation allows users to remove the collection cup when only small amounts of juice are needed, reducing the overall device size and improving handling ease while maintaining convenient juice collection when the cup is attached.
4Device complexity
If the sieve insert with support bracket remains in the container during pressing, then the structure is simpler, but the pressed fruit juice flushes out coarser fruit components when poured out
Solution Approach 1:
The sieve insert and support bracket are merged into a single integrated component that is connected to the first lever arm rather than remaining in the container. This integration ensures that the sieve moves with the lever arm during pressing, maintaining structural simplicity while preventing juice contamination by keeping the sieve away from the pouring path of the collected juice.
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 simplifies juice extraction and handling by allowing precise dosing and easy cleaning, enhancing usability and reducing the complexity of the fruit press, especially for small juice requirements.
Implementation Method 1
The fruit press has a first lever arm (4) and a second lever arm (6), which are connected to one another at respective ends via a joint (8)
Implementation Method 2
The sieve (20) has a plurality of sieve openings (20a), through which pressed fruit juice can run off

AI summary
The present invention relates to a hand-operated fruit press (2) with a first and a second lever arm (4, 6) which are connected to one another via a joint (8), the joint (8) being at one end of the lever arms (4, 6), the lever arms (4, 6) each have a handle (10) at their ends facing away from the joint (8), with the first lever arm (4) there is a connecting rod between the handle (10) and the joint (8 ) arranged sieve (20) is connected to an associated support stand (22) and a collecting cup (12) arranged underneath, and the second lever arm (6) is connected to a pressing body (14) which, when the two lever arms (4, 6 ) exerts pressure on a piece of fruit placed in a pressing chamber (24) formed between the sieve (20) with the associated support stand (22) and the pressing body (14). In order to change the fruit press so that it is easier to handle, it is proposed that the sieve (20) including the associated support (22) be connected directly to the first lever arm (4), the collecting cup (12) be placed below the sieve (20 ) is arranged and detachably connected to the first screen (20) including the associated support bracket (22) and/or the first lever arm (4).
