Removable Grinder and Press Chamber Design for Easy-Clean Juicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing juicing devices often compromise on juice quality due to heating, aeration, particulate introduction, and residual flavor/color issues, and are inefficient with diverse food types, requiring extensive cleaning and assembly.
Innovation Solution
A cold pressing juicing device with a separate grinder and press mechanism, using a disposable filter and self-filtration network to maintain juice quality, and a design that prevents food fibers from sticking, allowing for easy cleaning and processing of various foods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If centrifugal force is used to spin pulp against a screen, then juice extraction speed is improved, but heating, aeration, and particulate introduction occur which decrease juice quality
Solution Approach 1:
The juicing process is divided into separate stages: grinding food material into pulp in a first chamber, then pressing the pulp against a screen in a second chamber. This segmentation allows each stage to be optimized independently, avoiding the harmful effects of combining high-speed centrifugal force with screen contact.
Solution Approach 2:
A screen is introduced as an intermediary element between the pulp and the pressing mechanism. The screen allows juice to pass through while retaining particulates, enabling filtration without the need for high-speed centrifugal force that would cause heating and aeration.
2Manufacturing precision
If a screen, cloth, or similar device is used to retain food particulate, then filtration is improved, but residual color and flavor are retained in the juicing device
Solution Approach 1:
The screen is designed to be removable from the juicing device. After use, the screen can be easily extracted and cleaned separately, allowing thorough removal of residual color and flavor that would otherwise contaminate the device for subsequent juicing operations.
Solution Approach 2:
The screen serves as a disposable or easily replaceable component that can be discarded after use or recovered for cleaning. This approach eliminates the problem of residual flavor and color buildup in fixed screening mechanisms.
3Manufacturing precision
If holes, slots, crevices, and anchor points are provided for filtration, then juice separation is improved, but food fibers and particulates are retained causing cleaning difficulties
Solution Approach 1:
The screen with its filtration holes and slots is designed as a separate, removable component. This allows the screen to be easily extracted and cleaned, eliminating the difficulty of cleaning fixed holes, slots, and crevices that would trap food fibers and particulates.
Solution Approach 2:
A porous screen material is used that provides efficient filtration through its pore structure, while the entire screen can be removed and cleaned to prevent food fiber retention in the juicing device itself.
4Productivity
If a cheese grater style blade is used to process fibrous foods, then cutting capability is improved, but fibers hook onto and lay over the cutting edges blunting the blades
Solution Approach 1:
The cheese grater style blade is separated from the pressing mechanism. Food is first ground into pulp, then the pulp is pressed against a screen without direct contact between fibrous materials and the cutting edges, preventing fiber accumulation and blade blunting.
Solution Approach 2:
The processing is segmented into grinding followed by pressing. This separation allows the use of a screen-based filtration system that does not suffer from fiber hooking and blade blunting issues inherent in direct contact grating mechanisms.
