Juicer Blade Segmentation for Pre-Cutting Without Nutrient Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juicers lose the unique taste and nutrients of juicing targets during high-speed crushing, struggle with extracting juice from stems and leaves of vegetables, and are ineffective for viscous fruits like mangoes and soy milk production, requiring users to manually cut targets to fit the juicer's size.
Innovation Solution
A juicer design with a blade divided into an upper and lower blade, cooperating with an inner hopper protrusion to cut juicing targets before reaching the screw, eliminating the need for manual pre-cutting and enhancing extraction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a high-speed blade is used to crush the juicing target, then the juicing process is fast, but the unique taste and nutrients are lost
Solution Approach 1:
The blade is segmented into multiple sections (first blade section, second blade section, third blade section) with different functions. The first section cuts the juicing target into small pieces, the second section further crushes them, and the third section presses against the mesh. This segmentation allows the blade to process juicing targets gently without high-speed crushing, preserving taste and nutrients while maintaining juicing efficiency.
2Object-affected harmful factors
If a low-speed screw is used to extract juice, then taste and nutrients are preserved, but the juicer cannot handle viscous fruits like mangoes
Solution Approach 1:
The blade performs preliminary cutting and crushing of the juicing target before it reaches the screw. By pre-processing the material into small pieces and pulp, the blade prepares the juicing target in advance, making it easier for the low-speed screw to extract juice even from viscous fruits like mangoes, thereby expanding the juicer's versatility.
3Productivity
If the screw size is reduced to accommodate smaller juicing targets, then extraction efficiency improves, but users must manually cut targets to fit size requirements
Solution Approach 1:
The blade automatically cuts and crushes the juicing target into appropriate sizes as it rotates, eliminating the need for users to manually pre-cut the targets. The blade's cutting action occurs automatically during the juicing process, allowing users to insert whole or large pieces of fruit, vegetables, or soybeans directly into the juicer.
4Adaptability or versatility
If a mesh and low-speed screw are used, then juice extraction from viscous fruits is improved, but the device complexity increases
Solution Approach 1:
The blade and screw are merged into a single integrated component, with the blade forming the outer periphery of the screw. This merging eliminates the need for separate cutting and extrusion mechanisms, simplifying the overall device structure while maintaining the ability to handle viscous fruits through the combined cutting and pressing actions.
