Automatic Juicing Cone Feed for Gentle Fruit Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users seek a simple automatic juicer that is gentle on fruits, unlike centrifugal or masticating juicers, but does not require manual pushing of the fruit onto an electrically turned juicing cone, as existing electric juicers can be rough on fruits and require manual operation.
Innovation Solution
An automatic juicer with a base containing a motor and gear assembly that includes a fixed guide and inner and outer shafts, where the inner shaft rotates and advances a vertically facing juicing cone into the fruit, releasing juice into a stationary bowl, with a mechanism to control the vertical movement and rotation of the juicing cone to avoid excessive force on the fruit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an electric motor rotates the juicing cone rapidly (centrifugal or masticating juicers), then juice extraction efficiency is improved, but the fruit is subjected to excessive force and rough treatment
Solution Approach 1:
Instead of rotating the fruit rapidly against a stationary cone (centrifugal) or grinding it (masticating), this invention inverts the approach by having the juicing cone rotate upward into the stationary fruit. The cone rotates slowly and pushes into the fruit from below, extracting juice through gentle compression rather than high-speed impact or grinding, thus maintaining extraction efficiency while avoiding excessive force on the fruit.
2Object-affected harmful factors
If a manual juicer is used, then gentle treatment of fruit is achieved, but user effort is required to push and rotate the fruit
Solution Approach 1:
The juicing cone is equipped with an automatic feed mechanism that uses a spring-loaded arm to detect when fruit is present and automatically pushes the fruit onto the rotating cone. Once the fruit is positioned, the rotating cone self-advances vertically into the fruit through threaded engagement with a nut, eliminating the need for users to manually push or rotate the fruit. The system performs these actions autonomously while maintaining gentle treatment of the fruit.
3Device complexity
If the juicing cone is made stationary and fruit is rotated manually, then simple construction is achieved, but automation is lost
Solution Approach 1:
The juicing cone transitions from a stationary component to a dynamically active one that performs multiple functions: it rotates horizontally to process the fruit, simultaneously advances vertically into the fruit through threaded engagement, and is automatically fed by a spring-loaded arm. This dynamic design enables full automation while maintaining relatively simple construction by combining multiple movements into a single integrated component rather than requiring separate mechanisms for each function.
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
The automatic juicer effectively releases juice from fruits without manually pushing them, providing a gentler operation than centrifugal or masticating juicers and simplifying the manufacturing process, while ensuring efficient juice extraction.
Implementation Method 1
The inner shaft includes threads to vertically advance and retreat a shaft nut and the outer shaft rotates with the inner shaft, but is lifted by the shaft nut when the inner shaft turns

AI summary
An automatic juicer turns and pushes an upward facing juicing cone into a fruit for releasing juice. The juicer includes a base containing a motor, gear and shaft assembly. A fixed guide extends upward from the base and inner and outer shafts reside inside the fixed guide and are driven by the motor and gear assembly to rotate and advance the juicing cone into the fruit. The inner shaft includes threads to vertically advance and retreat a shaft nut and the outer shaft rotates with the inner shaft, but is lifted by the shaft nut when the inner shaft turns. The juicing cone releases the juice and a stationary bowl catches the juice.
