Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juice extractors with mesh structures suffer from low juice-extracting efficiency due to blockages by debris and difficulty in cleaning, as well as issues with debris decay and germ propagation.
Innovation Solution
A juice-extracting drum composed of two modules, with an inner module featuring slits and an outer module with ribs that form a fixed gap for juice discharge, allowing easy assembly, cleaning, and preventing debris hindrance, while maintaining a constant discharge interval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mesh structure is used in the juice-extracting drum, then filtration function is provided, but juice-extracting efficiency decreases due to blockages by debris
Solution Approach 1:
The drum structure is divided into two separate modules: an inner module with slits for juice discharge and an outer module with ribs for structural support. This segmentation allows the juice discharge paths to remain open without mesh blockages while still providing filtration through the slit design, thereby maintaining filtration function while improving juice-extracting efficiency
Solution Approach 2:
The invention extracts the filtration function from the traditional mesh structure and relocates it to the slit design in the inner module. By taking out the mesh component entirely, the patent eliminates the blockage problem while preserving the essential filtration capability through the geometric configuration of the slits and ribs
2Reliability
If a mesh structure is used in the juice-extracting drum, then filtration is provided, but cleaning difficulty increases due to debris stuck in netted holes
Solution Approach 1:
By segmenting the drum into detachable inner and outer modules, the patent enables easy access to all surfaces requiring cleaning. The inner module can be removed independently, allowing thorough cleaning of the slits and juice discharge paths without disassembling the entire drum structure, thus significantly improving cleaning ease while maintaining filtration function
Solution Approach 2:
By extracting the mesh structure from the design, the patent eliminates the primary source of cleaning difficulty. The slit design in the inner module presents no recesses or tangled wires for debris to become trapped in, making cleaning straightforward while preserving the necessary filtration capability
3Productivity
If circular netted holes are formed in the drum, then juice discharge is enabled, but debris decay and germ propagation occur when debris is not fully removed
Solution Approach 1:
The segmented design with the inner module featuring slits provides unobstructed juice discharge paths that prevent debris accumulation. The geometric configuration ensures that juice flows freely through the slits without creating stagnant areas where debris could decay or germs could propagate, while still enabling effective juice discharge
Solution Approach 2:
By removing the mesh structure with its circular holes, the patent eliminates the crevices and dead zones where debris could become trapped and decay. The slit design ensures complete juice flow through the discharge paths, preventing the conditions necessary for debris decay and germ propagation while maintaining juice discharge functionality
4Productivity
If a modular design with two modules is used, then cleaning ease and juice-extracting efficiency are improved, but device complexity increases
Solution Approach 1:
The drum is divided into two functional modules: the inner module containing the slits for juice discharge and the outer module with ribs for structural support. This segmentation improves cleaning ease and juice-extracting efficiency by allowing independent access and maintenance of each module, while the modular design itself is kept simple through straightforward geometric forms and direct assembly relationships
Solution Approach 2:
The inner and outer modules are combined through a simple assembly relationship where the inner module fits within the outer module structure. The ribs of the outer module align with the slits of the inner module to maintain structural integrity and functional performance, creating a unified drum assembly that retains the simplicity of traditional single-piece designs while enabling modular maintenance advantages
