Lemon juicing assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lemon juicers require users to manually slice the lemon before squeezing, which can be inefficient and require additional effort.
Innovation Solution
A juicing device with a first lever integrated cup and a pivotally coupled second lever that includes a plunger, allowing for simultaneous slicing and squeezing of the lemon without prior cutting, using a blade within the cup to slice the lemon as it is compressed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a manual slicing step is added before juicing, then the juicing process becomes more complete, but the user effort and time required increase
Solution Approach 1:
The patent combines the slicing function and juicing function into a single integrated device. The blade is positioned within the cup to slice the lemon as it is being compressed, eliminating the need for separate slicing and juicing operations. This merging of functions directly resolves the contradiction by maintaining complete juice extraction while reducing user effort and time.
Solution Approach 2:
The blade is pre-positioned within the cup in the correct slicing position before use. When the lemon is placed in the cup and compressed, the slicing action occurs automatically as a preliminary step to juicing, without requiring the user to manually slice first. This preliminary positioning enables efficient simultaneous slicing and juicing.
2Productivity
If multiple levers are used for slicing and squeezing, then the juicing function is enhanced, but the device complexity increases
Solution Approach 1:
The second lever is designed to perform multiple functions: it applies compression force through the plunger for juicing, and simultaneously guides the lemon against the blade for slicing. This multi-functional lever reduces the need for separate mechanisms, enhancing juicing capability while controlling device complexity.
Solution Approach 2:
The plunger is integrated within the second lever structure, and the blade is positioned within the cup. This nested arrangement allows compact integration of multiple functional elements (lever, plunger, blade, cup) in a space-efficient manner, enhancing functionality without proportionally increasing complexity.
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
Enables efficient and effortless juice extraction from lemons by integrating a blade within the cup for slicing and a plunger for compression, reducing user effort and eliminating the need for pre-slicing.
Implementation Method 1
a plunger integrated therein. The second lever is positionable in a closed position having the second lever lying on the first lever. Thus, the plunger compresses the lemon into the cup
Implementation Method 2
A blade is fixed in the cup to slice the lemon when the lemon is urged downwardly in the cup

AI summary
A lemon juicing assembly for squeezing juice from a lemon includes a first lever that has a cup integrated therein to receive a lemon. A blade is fixed in the cup to slice the lemon when the lemon is urged downwardly in the cup. A second lever is pivotally coupled to the first lever and a plunger is integrated therein. The second lever is positionable in a closed position having the second lever lying on the first lever. Thus, the plunger compresses the lemon into the cup. In this way the lemon is sliced and the juice is squeezed from the lemon. The second lever is positionable in an open position having the second lever extending away from the first lever.
