Juicer Fastening Guide Structure to Prevent Ground Material Backflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juicers using the pair gear method face issues with juice extraction efficiency and backflow of ground material due to high pressure, leading to residual heavy metals in the extracted juice.
Innovation Solution
A juicer design incorporating a fastening guide structure with a hollow fastening guide and sealing members at the coupled portion between the drive part and the roller part, enhancing sealing force to prevent backflow and improve juice extraction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pair gear method is used to extract juice, then the juice extraction rate is improved, but ground material flows back from the grinding parts to the drive part due to high pressure
Solution Approach 1:
A fastening guide structure is introduced as an intermediary component between the drive part and roller part. This structure includes a fastening guide with a through-hole that receives the rotary shaft, and sealing members (O-rings or gaskets) that act as mediators to prevent ground material from flowing back along the rotary shaft while allowing rotational movement. This resolves the contradiction by maintaining the high-pressure juicing function while blocking the backflow path.
Solution Approach 2:
The coupling between the drive part and roller part is segmented into distinct functional zones: the fastening guide structure separates the rotational drive function from the juicing function. The sealing members are positioned at specific locations (front and rear ends of the fastening guide) to create segmented sealing zones that prevent backflow without interfering with the grinding and juicing operations. This segmentation allows each component to perform its specific function effectively.
2Reliability
If sealing members are added to prevent backflow, then the sealing force is improved, but the device complexity increases
Solution Approach 1:
The fastening guide structure serves multiple functions simultaneously: it acts as a fastening component to secure the rotary shaft, a sealing structure to prevent ground material backflow, and a support element for the roller part. The sealing members are integrated into this multi-functional component rather than being separate additions. This universality reduces overall device complexity while maintaining effective sealing.
Solution Approach 2:
The sealing members are implemented as flexible O-rings or gaskets that can deform to accommodate the rotary shaft and maintain sealing contact under high-pressure conditions. These thin film-like sealing elements provide effective sealing without adding significant structural complexity, as they can be easily installed within the fastening guide's through-hole and adapt to the rotational movement.
