Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juice-extracting drums with mesh structures suffer from low efficiency due to blockages by debris and difficulty in cleaning, as well as issues with germ propagation and clogging, especially when fine circular netted holes are used.
Innovation Solution
A juice-extracting drum composed of two modules, an inner hollow cylinder with slits and an outer module with ribs, allowing for easy assembly and disassembly, improved juice extraction efficiency, and effective debris removal, with the rib structure preventing debris from hindering juice flow and maintaining a constant gap for efficient juice discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a mesh structure is used in the juice-extracting drum, then filtration function is provided, but juice-extracting efficiency is low due to blockages by debris
Solution Approach 1:
The drum is divided into two detachable modules: an inner module with slits for juice discharge and an outer module with a mesh structure for filtration. This segmentation allows the mesh to be separated from the juice discharge path, preventing debris blockages from affecting overall extraction efficiency while maintaining filtration function.
Solution Approach 2:
A gap is introduced between the inner module and outer module, serving as an intermediary space that allows juice to flow freely from the slits in the inner module through the gap to the mesh structure of the outer module. This intermediary gap prevents direct contact between debris and the mesh, reducing blockages.
2Ease of manufacture
If a mesh structure is used in the juice-extracting drum, then filtration function is provided, but cleaning to remove debris is difficult
Solution Approach 1:
By dividing the drum into two detachable modules, the mesh structure in the outer module can be easily separated from the inner module for independent cleaning. This segmentation makes it simple to remove and clean the mesh structure without disassembling the entire drum, significantly improving cleaning ease while maintaining filtration performance.
3Manufacturing precision
If fine circular netted holes are used, then filtration precision is improved, but debris may decay and germs may propagate due to difficulty in cleaning
Solution Approach 1:
The detachable two-module design allows the outer module with fine mesh to be easily separated and cleaned. This segmentation enables thorough cleaning of the fine mesh structure to remove all debris, preventing decay and germ propagation while maintaining high filtration precision.
Solution Approach 2:
The design enables easy self-cleaning of the mesh structure by the user. The outer module can be readily detached and cleaned without requiring special tools or complex procedures, ensuring that fine mesh holes remain free of debris that could lead to germ propagation.
4Ease of manufacture
If the drum is composed of two modules, then cleaning ease is improved, but device complexity increases
Solution Approach 1:
The drum is segmented into two modules that connect through a simple coupling mechanism between the inner and outer modules. This segmentation improves cleaning ease by allowing easy separation, while the coupling mechanism is designed to be simple enough that it does not significantly increase overall structural complexity.

AI summary
A juice-extracting drum includes a screw rotating inside. An inner module includes a hollow cylinder with an upper portion having the screw. A plurality of slits are formed as penetration holes having both lateral sides, an upper surface, and a lower surface along an interior circumference. An outer module is detachably coupled to the inner module, and includes a rib protruding in a radially interior direction on an interior circumference. The rib is inserted into the slit of the inner module when the outer module surrounds and combines the inner module. A predetermined fixed gap discharging juice extracted by the screw is formed lengthily in an up and down direction between the lateral side of the slit of the inner module and a lateral side of the rib of the outer module. The fixed gap is formed in a direction intersecting the screw blade.
