Worm Gear Sweeper and Filter Assembly for Compact Juicer Pulp Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing juicer designs require significant space for cleaning systems due to elements like carrier strips or bands, which is problematic for compact automated tabletop juicers.
Innovation Solution
A sweeper and filter assembly with a worm gear and geared motor configuration that allows efficient pulp removal without the need for additional cleaning elements, featuring a casing with separate outlets for juice and fruit remains, and a worm gear shaft connected to a geared motor for mechanical operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If carrier strips or bands are used for filter cleaning, then cleaning effectiveness is improved, but device space requirements increase
Solution Approach 1:
The patent extracts the cleaning function from the traditional carrier strip system and implements it through a compact worm gear mechanism with integrated scrapers. The worm gear shaft with attached scrapers directly contacts and cleans the filter surface, eliminating the need for extensive carrier strips while maintaining effective pulp removal.
Solution Approach 2:
The invention merges the drive mechanism and cleaning function into a single integrated worm gear assembly. The geared motor drives the worm gear shaft, which simultaneously performs the sweeping action through integrated scrapers, combining multiple functions into a compact unit that reduces overall device space.
2Reliability
If complex cleaning mechanisms are used, then cleaning capability is improved, but device complexity increases
Solution Approach 1:
The worm gear mechanism provides self-contained cleaning action where the geared motor directly drives the worm gear shaft with integrated scrapers. The system serves itself by using the same mechanical components for both drive and cleaning functions, eliminating the need for separate complex cleaning mechanisms.
Solution Approach 2:
The worm gear shaft serves multiple functions: it transmits mechanical power from the geared motor and simultaneously acts as a mounting structure for scrapers that perform filter cleaning. This multi-functionality reduces the number of separate components needed, simplifying the overall device while maintaining effective cleaning capability.
