Juicer with Segmented Cutting and Sieving for Consistency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kitchen appliances for juicing and blending are limited in their ability to produce beverages with customizable consistency, often resulting in tasteless drinks due to dilution or restricted consistency options, and are complex to control.
Innovation Solution
A juicer with a rotary cutter and centrifugal sieve system that allows independent control of cutting and sieving processes, enabling the production of clear juice, cloudy juice, thin smoothie, or thick smoothie by varying the cutting time and speed, with the sieve operation driven by centrifugal forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a peeling tube is inserted into a centrifuge drum to control juice thickness, then consistency selection is improved, but device complexity increases and control becomes difficult
Solution Approach 1:
The juicing process is segmented into two independent stages: cutting/blending stage and sieving stage. The cutting tool and rotary sieve can operate independently with separate control, allowing the user to first cut the ingredients to desired particle size, then separately control the sieving process to achieve different consistencies without complex mechanical adjustments
Solution Approach 2:
The system uses variable speed control for both the cutting tool and rotary sieve, allowing dynamic adjustment of operating parameters. The drive system enables independent speed variation of each component, providing flexible control over juice consistency through simple speed adjustments rather than complex mechanical configurations
2Manufacturing precision
If blending time is increased to achieve finer particle size, then juice consistency control is improved, but processing time increases
Solution Approach 1:
The cutting tool performs preliminary size reduction of ingredients before they enter the rotary sieve. This pre-processing step creates uniformly sized particles that can then be efficiently separated by the sieve, achieving fine particle size control without requiring excessive blending time in the second stage
Solution Approach 2:
The two-stage process operates continuously with the cutting tool and rotary sieve working in sequence. Ingredients are continuously cut and then continuously sieved, maintaining constant useful action throughout the process and minimizing idle time while achieving precise particle size and consistency control

Function Achieved in This Case
Enables flexible control over juice consistency based on operation time sequences, optimizing each process for different fruits and vegetables, providing a simple-to-use and manufacture appliance that meets personal taste and health needs.
Implementation Method 1
The sieving is based on a centrifugal process by which juice is forced through the rotating sieve by centrifugal forces

AI summary
A juicer combines a tool such as a rotary cutter and a rotary sieve. After processing with the tool (e.g. blending) the food to be juiced is passed to the rotary sieve. The processing time with the tool dictates the consistency of the eventual output.
