Adjustable Juicer Filter Collar for Fiber Content Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juicers either lose nutritional value by separating insoluble dietary fiber from juice or result in an unappealing pulp-juice mixture, failing to provide a controllable amount of insoluble dietary fiber in the final product.
Innovation Solution
A centrifugal juicer design featuring a cutter disk, motor assembly, collar, and elevator assembly allows for adjustable filter hole size through a deflector rod and gear system, enabling control over the amount of insoluble dietary fiber in the juice without stopping the motor, allowing for pure juice or juice with varying fiber content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal foil filter mesh is used to separate pulp and juice, then pure clear juice is obtained, but insoluble dietary fiber and nutrients are lost
Solution Approach 1:
The patent applies the dynamics principle by making the filter mesh structure adjustable rather than fixed. The filter mesh can be dynamically adjusted between different positions to control the filtration degree, allowing users to switch between obtaining pure juice and retaining dietary fiber based on their needs. This resolves the contradiction by transforming a static separation system into a dynamic one that can adapt to different requirements.
2Productivity
If pulp discharge structure is used to achieve clear liquid, then filtration is effective, but nutriment in pulp is lost
Solution Approach 1:
The patent uses a dynamically adjustable filter mesh that can change its position and filtration area during operation. By adjusting the filter mesh to different positions, the system can control how much pulp passes through, thereby controlling the amount of dietary fiber and nutrients retained in the juice while maintaining effective filtration when needed.
Solution Approach 2:
The patent changes the physical parameters of the filtration system by adjusting the filter mesh position and the effective filtration area. This parameter adjustment allows the system to vary between high filtration efficiency mode (for pure juice) and low filtration mode (for retaining nutrients), resolving the contradiction between filtration efficiency and nutrient retention.
3Loss of substance
If no pulp discharge structure is used, then compound of pulp and juice is obtained, but the amount of pulp affects the whole taste
Solution Approach 1:
The patent applies dynamics by providing an adjustable filter mesh that allows users to control the amount of pulp in the juice. Users can adjust the filter mesh to achieve the desired balance between retaining dietary fiber and controlling pulp content for optimal taste, rather than having a fixed pulp-juice mixture.
4Adaptability or versatility
If filter hole size is adjusted to control fiber content, then health benefits are optimized, but device complexity increases
Solution Approach 1:
The patent uses a relatively simple dynamic adjustment mechanism where the filter mesh can be moved between different positions. This dynamic structure allows control over fiber content without requiring complex mechanisms, achieving adaptability while maintaining reasonable device simplicity.
Solution Approach 2:
The patent controls fiber content by changing the physical parameter of filter hole exposure area through simple positional adjustment of the filter mesh. This parameter change approach achieves versatility in fiber content control without introducing excessive device 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 the production of juice with a controllable amount of insoluble dietary fiber, promoting health benefits like intestinal peristalsis and calcium intake, while allowing quick and convenient adjustment of fiber content based on food type and taste preferences.
Implementation Method 1
As the cutter disk generates centrifugal force in high speed, pulp of fruits and vegetables fly off the metal foil filter mesh into the pulp container
Implementation Method 2
pulp of fruits and vegetables fly off the metal foil filter mesh into the pulp container, while fruits and vegetables juice pass through the metal foil filter mesh flow into juice glass

AI summary
The invention discloses a juicer, includes a base (1), a motor assembly (2), a cutter disk (3), a collar (5) and an elevator assembly (6). The elevator assembly is configured for lifting up or lowering down the collar in accordance to user's operations, as a result a distance between the collar and the cutter disk is adjusted and the area of each filter hole (31) that being covered or sealed by the collar is adjusted. The present invention can realize changing the size of filter holes, to control fiber flow through. Thus pure juice and different content of insoluble dietary fiber vegetables and fruits juice can be obtained.
