Squeezing system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fruit squeezers with parallel rotating axles require large machinery, suffer from fruit rejection and size issues, and have laborious disassembly for cleaning, leading to inefficiencies and potential breakages due to material fatigue.
Innovation Solution
A squeezing system with female and male drums having axles deployed at an angle, with one base larger than the other and a frustoconical shape, allowing for synchronized rotation and engagement of protuberances with cavities, utilizing a guide and retention subsystem to maintain fruit alignment and shape during juicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If parallel rotation axles are used in the squeezing system, then the structure is simpler to manufacture, but the machinery size becomes large and material fatigue causes breakages
Solution Approach 1:
The patent applies asymmetry by deploying the rotation axles of the male and female drums at an angle other than parallel (0° or 180°). This angular arrangement creates an asymmetric configuration that eliminates the bending moments and deformation issues inherent in parallel axle systems, thereby preventing material fatigue and breakages while maintaining structural integrity during operation.
Solution Approach 2:
The patent transitions from a two-dimensional parallel axle arrangement to a three-dimensional angular axle configuration. By introducing an angular dimension between the axles, the system achieves better mechanical stability and reduces stress concentration, thereby improving reliability without significantly complicating the manufacturing process.
2Ease of manufacture
If parallel rotation axles are used, then the device is easier to assemble, but cleaning requires laborious disassembly
Solution Approach 1:
The patent employs segmentation by designing the squeezing system with modular components that can be easily separated. The angular axle configuration naturally creates separation between the male and female drum assemblies, allowing them to be quickly detached for cleaning without requiring complete disassembly of the entire mechanism, thus improving cleaning accessibility while maintaining assembly simplicity.
3Productivity
If the squeezing system is designed for high productivity, then more fruit can be processed, but the machinery size increases
Solution Approach 1:
The patent applies merging by integrating multiple functional elements into a compact angular axle configuration. The male and female drums are positioned closer together with the angular arrangement, allowing for more efficient space utilization and enabling higher processing capacity within a smaller overall machinery volume compared to traditional parallel axle systems.
