Solution Overview
Problem
Conventional juicers with mesh structures face issues such as clogging, difficulty in cleaning, and noise due to residue accumulation and the design of screw threads that hinder smooth juice extraction and material transport.
Innovation Solution
A separable screw composed of two modules with slits and ribs, featuring a groove on the upper spiral protrusion to facilitate easy assembly, cleaning, and smooth juice extraction, while preventing residue accumulation and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mesh structure is used for the juicing drum, then filtration function is improved, but cleaning difficulty increases and clogging occurs
Solution Approach 1:
The juicing drum is divided into multiple segments with through-type grooves that allow residue to pass through freely. This segmentation eliminates the mesh structure that causes clogging and cleaning difficulties, while still providing effective filtration through the groove design.
Solution Approach 2:
Instead of using a traditional mesh structure that traps residue, the invention inverts the approach by using open grooves that allow residue to pass through. This inversion resolves the contradiction by providing filtration without the clogging and cleaning issues inherent in mesh structures.
2Device complexity
If the screw thread maintains a uniform gap with the mesh drum, then structural simplicity is improved, but noise and clogging increase
Solution Approach 1:
The screw thread design incorporates local variations in gap width, with the gap being narrower at certain locations and wider at others. This local quality variation prevents residue accumulation and reduces noise without significantly complicating the overall structure.
Solution Approach 2:
The invention changes the gap parameter of the screw thread from a uniform value to a variable value that changes along the thread length. This parameter change effectively reduces noise and prevents clogging while maintaining reasonable structural simplicity.
3Ease of manufacture
If residue is not thoroughly cleaned from mesh pores, then manufacturing simplicity is improved, but bacterial proliferation and rot occur
Solution Approach 1:
The through-type groove structure divides the juicing drum into accessible segments that can be easily cleaned. This segmentation maintains manufacturing simplicity while eliminating the hidden spaces where residue would accumulate and cause bacterial proliferation.
4Ease of operation
If a separable screw design is used, then cleaning ease is improved, but device complexity increases
Solution Approach 1:
The screw is divided into modular segments that can be easily separated for cleaning and reassembled afterward. This segmentation dramatically improves cleaning ease while the modular design actually simplifies manufacturing and assembly compared to a monolithic screw.
