Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing juicers face inefficiencies and low juice yield due to food residue accumulating or stirring upwards at the feed inlet, blocking the process and preventing unsqueezed food from entering the squeezing chamber effectively.
Innovation Solution
A juicer design featuring a buffer chamber between the threaded cutter and the feed inlet, with a radial projecting top and a pivot joint, prevents food from splashing and accumulating, ensuring continuous squeezing and increased juice yield by forming an isolation area and facilitating the processing of food within the squeezing chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If food is fed into the juicer at high speed, then processing efficiency is improved, but food residue accumulates at the feed inlet and threaded cutter, blocking the feed inlet and obstructing food from entering the squeezing chamber
Solution Approach 1:
A buffer chamber is introduced as an intermediary space between the feed inlet and the threaded cutter. This buffer chamber receives food residue that would otherwise accumulate and block the feed inlet, allowing continuous feeding while preventing obstruction. The buffer chamber acts as a mediator that decouples the feeding process from the squeezing process, enabling high-speed feeding without blockage.
2Productivity
If the threaded cutter rotates rapidly to increase juice extraction speed, then productivity is improved, but food residue stirs upwards in the feed inlet, causing blockage
Solution Approach 1:
The harmful effect of food residue being stirred upwards by the rotating threaded cutter is extracted and isolated into a separate buffer chamber. Instead of allowing the residue to mix with and block the feed inlet during rapid rotation, the buffer chamber captures and contains the residue, separating the harmful stirring action from the feeding pathway.
3Device complexity
If the feed inlet is positioned close to the threaded cutter for compact design, then device complexity is reduced, but food residue accumulates at the interface between feed inlet and threaded cutter
Solution Approach 1:
The space between the feed inlet and threaded cutter is segmented into two functional zones: the buffer chamber for receiving and containing food residue, and the feed inlet pathway for continuous food supply. This segmentation allows the components to remain close for compactness while preventing residue accumulation from blocking the feed pathway.
