Problem

Existing citrus juicers often suffer from inefficiencies and hygiene issues due to manual pressing, leading to juice spillage and suboptimal juice collection.

Innovation Solution

A device with a receiving element and a pressing element that allows for translational movement along a defined axis, featuring angled cutting lines and guided support structures to enhance juice retention and collection, while facilitating easy cleaning and one-handed operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual pressing is used in existing citrus juicers, then the device is simple to operate, but juice spillage occurs and hygiene is compromised

Engineering Contradiction:
Improvemanual operation simplicityVSAvoidjuice retention and hygiene
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The pressing element is divided into multiple pressing surfaces (first pressing surface and second pressing surface) that can independently contact different regions of the citrus segment. This segmentation allows for controlled pressing action that prevents juice spillage while maintaining ease of manual operation. The receiving element is also segmented with a receiving chamber that specifically positions the citrus segment to ensure hygienic juice collection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pressing element acts as an intermediary between the user's manual force and the citrus segment. It translates manual pressure into controlled compression while directing juice flow into the receiving chamber. This intermediary mechanism ensures that manual operation remains simple while achieving reliable juice retention and hygiene through the structured interaction between pressing and receiving elements.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the pressing element is fixed, then the structure is simple, but juice collection efficiency is reduced

Engineering Contradiction:
Improvepressing element structureVSAvoidjuice collection efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The pressing element is designed to be movable relative to the receiving element along a pressing axis, transforming a static structure into a dynamic one. This movement capability allows the pressing element to apply controlled compression force to the citrus segment, significantly improving juice extraction efficiency. The dynamic design maintains relative structural simplicity while enabling efficient juice collection through the pressing motion.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If the receiving surface is parallel to the pressing axis, then manufacturing is easier, but juice collection and retention are improved

Engineering Contradiction:
Improvereceiving surface orientationVSAvoidjuice retention
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The receiving surface is designed with an asymmetric orientation relative to the pressing axis, forming a specific angle that optimizes juice flow direction. This asymmetric design improves juice retention by directing collected juice toward the spout while maintaining ease of manufacture through simple angular geometry. The asymmetric configuration ensures that juice does not spill back during pressing while keeping the manufacturing process straightforward.

Inventive Principle:
Principle #4Asymmetry

4Productivity

If the pressing element extends fully within the receiving chamber, then pressing effectiveness is maximized, but cleaning access is difficult

Engineering Contradiction:
Improvepressing effectivenessVSAvoidcleaning accessibility
Core Design Contradiction:
ProductivityVSEase of repair

Solution Approach 1:

The pressing element is designed as a separate, removable component that can be detached from the receiving element. This segmentation allows the pressing element to extend fully within the receiving chamber during operation for maximum pressing effectiveness, while also enabling easy removal for cleaning. The modular design ensures that both pressing effectiveness and cleaning accessibility are optimized without compromise.

Inventive Principle:
Principle #1Segmentation
