Juicing unit and fruit juicing machine that includes said juicing unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fruit juicing machines often include additional components that can cause issues such as breakages, assembly and disassembly difficulties, and the accumulation of dirt or fruit remains due to complex designs.
Innovation Solution
A squeezer unit with two female drums and two male drums, each with a central shaft, that rotate in opposite directions, coupled with a support featuring a frontal plate with protrusions, reducing the number of components and eliminating the need for stop tabs that can cause dirt accumulation, while enhancing robustness and preventing shaft splay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional components (such as stop tabs, separate support structures) are included in the juicing machine, then the functionality and reliability are improved, but the device complexity increases and difficulty of assembly/disassembly worsens
Solution Approach 1:
The patent combines multiple functions into integrated components. The frontal plate is merged with the support structure, and stop tabs are integrated directly into the male drum bodies rather than being separate components. This merging reduces the total number of parts while maintaining all necessary functions, directly resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The frontal plate serves multiple functions: it supports the male drums, provides mounting positions for stop tabs, and acts as a structural connection element. The male drums simultaneously perform rotation for juicing and provide integrated stop tabs for positioning. This multi-functionality reduces component count while maintaining reliability.
2Reliability
If additional components (such as stop tabs, complex support structures) are included in the juicing machine, then the functionality is improved, but ease of manufacture worsens due to more assembly and disassembly operations
Solution Approach 1:
The stop tabs are merged into the male drum bodies as integral features rather than separate attachable components. The frontal plate is combined with the support structure, eliminating the need for separate mounting operations. This integration significantly simplifies manufacturing and assembly while maintaining structural stability.
3Reliability
If complex components (such as stop tabs, multiple support elements) are included in the juicing machine, then the functionality is improved, but object-generated harmful factors worsen due to dirt accumulation in hollows
Solution Approach 1:
The frontal plate is merged with the support structure to eliminate hollow spaces where dirt could accumulate. The stop tabs are integrated into the male drum bodies without creating enclosed hollows. This design maintains operational reliability while eliminating surfaces that would trap dirt and fruit remains.
4Ease of manufacture
If the number of components is reduced in the squeezer unit, then ease of manufacture is improved, but reliability may worsen due to fewer supporting elements
Solution Approach 1:
The frontal plate performs multiple structural functions simultaneously: it supports the male drums, provides positioning for stop tabs, and connects to the overall support structure. The male drums provide both rotational juicing function and integrated stop tab positioning. This multi-functionality ensures structural reliability is maintained despite reduced component count.
