Problem
Conventional citrus-fruit squeezers are bulky, difficult to clean, and require significant space, making them cumbersome to handle and maintain, especially in narrow environments, while also generating excessive waste and being less efficient in juice production.
Innovation Solution
A compact citrus-fruit squeezer design featuring a single female drum and a single male drum with inclined shafts, allowing for easy disassembly and cleaning, utilizing a cam transmission system to optimize motor power and reduce waste, and incorporating a paddle and feeder for efficient fruit handling and juice collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional citrus-fruit squeezers use four drums (two female and two male), then the squeezing capacity and juice production are improved, but the device dimensions and bulkiness increase significantly
Solution Approach 1:
The patent combines multiple squeezing functions into a single female drum by equipping it with multiple cavities (at least two cavities arranged side by side), which can accommodate multiple fruit portions simultaneously. This merging approach allows one male drum to work with one female drum containing multiple cavities, eliminating the need for separate drum pairs while maintaining multi-fruit processing capability, thus reducing overall device volume.
Solution Approach 2:
The patent arranges multiple cavities side by side in the same drum along a horizontal dimension, rather than stacking drums vertically or using multiple drum pairs. This dimensional reorganization allows multiple fruits to be processed in parallel within a single drum assembly, reducing the device's footprint while maintaining high productivity.
2Productivity
If conventional citrus-fruit squeezers use four drums and high-powered motors, then the squeezing effectiveness is improved, but the device complexity and difficulty of disassembly increase
Solution Approach 1:
The patent merges multiple cavities into a single female drum structure, reducing the total number of drums from four to two (one female and one male). This consolidation simplifies the overall mechanism, reduces the number of shafts and motors needed, and makes the device easier to assemble and disassemble for cleaning and maintenance.
Solution Approach 2:
The female drum is designed with multiple cavities that can process multiple fruit portions simultaneously, making a single drum assembly perform the work of multiple drums. This multi-functional design reduces component count while maintaining or enhancing productivity.
3Productivity
If conventional citrus-fruit squeezers use multiple drums, then the squeezing capacity is improved, but the ease of cleaning and maintenance deteriorates
Solution Approach 1:
By consolidating multiple cavities into a single female drum, the patent reduces the number of separate components that need to be disassembled for cleaning. The simplified structure with fewer drums and shafts allows for easier access to internal mechanisms, making cleaning and maintenance more straightforward while maintaining multi-fruit processing capability.
4Productivity
If conventional citrus-fruit squeezers are designed for high power output, then the juice extraction efficiency is improved, but the device weight and portability worsen
Solution Approach 1:
The patent consolidates the squeezing mechanism into fewer, more efficient components. By using a single female drum with multiple cavities and one male drum, the system reduces the total motor power required compared to driving four separate drums, while maintaining high juice extraction efficiency through optimized cavity-male drum engagement.
