Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing citrus juicers that extract juice from whole citrus fruits often require significant manual effort, result in low yield, and compromise juice quality due to contact with citrus peel oils and pollutants, making them unsuitable for domestic use.
Innovation Solution
A citrus press with a rotating pressing cone and movable pressing dome, equipped with radial knives and spacer members, which cuts the fruit into segments while preventing peel contact and facilitating juice extraction without excessive pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a perforated tube is used to extract juice from a whole citrus fruit, then the device structure is simple, but significant manual effort is required and the yield is not very high
Solution Approach 1:
The citrus fruit is divided into segments by radial knives that cut the fruit into portions as it rotates between the pressing dome and pressing cone. This segmentation allows juice extraction from multiple sections simultaneously, significantly increasing yield compared to single-point extraction methods while maintaining a relatively simple device structure.
Solution Approach 2:
The pressing dome is made movable relative to the pressing cone, allowing dynamic adjustment of the pressing force and position. This dynamic mechanism enables efficient juice extraction with reduced manual effort by automatically adapting to the fruit's position and resistance, while the rotary drive system provides continuous motion for consistent extraction throughout the fruit.
2Productivity
If lateral pressing force is applied to extract juice from a whole citrus fruit, then sufficient juice can be extracted, but significant manual intervention is required
Solution Approach 1:
The movable pressing dome combined with rotary drive creates a dynamic pressing system that automatically applies and adjusts lateral pressing force as the fruit rotates. This eliminates the need for continuous manual intervention while maintaining efficient juice extraction, as the mechanism self-regulates the pressing action throughout the rotation cycle.
Solution Approach 2:
The device is designed to perform the pressing action automatically through its mechanical configuration. The fruit's own rotation between the fixed pressing cone and movable pressing dome generates the necessary pressing force, with the system self-regulating through the mechanical interaction rather than requiring external manual control for each pressing action.
3Ease of operation
If the fruit is flattened after opening the press, then the skin can fall into a waste bin, but the essential oils and pollutants from the bark mix with the juice
Solution Approach 1:
The pressing cone features a central hollow point that extracts juice through the center of the fruit, separating the juice extraction path from the skin contact areas. This central extraction method allows the skin to be flattened and disposed of separately while the juice is collected through the center, preventing contamination from essential oils and pollutants in the bark and flavedo.
Solution Approach 2:
The central hollow point of the pressing cone acts as an intermediary extraction path, channeling juice through the center of the fruit away from the skin surfaces. This intermediary extraction route prevents direct contact between the collected juice and the contaminated skin, allowing convenient skin disposal while maintaining juice quality.
4Productivity
If a combined compression and suction system is used, then juice extraction can be enhanced, but the device becomes difficult to transpose to a reduced scale for domestic use
Solution Approach 1:
The device employs a suction system that uses air flow to extract juice from the fruit segments as they pass between the pressing surfaces. This pneumatic extraction method enhances juice removal efficiency without requiring complex mechanical compression systems, allowing the device to be scaled down to a compact size suitable for domestic use while maintaining effective juice extraction capability.
