Solution Overview

Problem

The existing methods for extracting juice from fruits like citrus fruits are inefficient, leading to wastage, messiness, and unpredictability, and are affected by seasonal fluctuations in fruit production, resulting in supply issues.

Innovation Solution

A sealed package containing a squeezable fruit segment with a flexible outer rind and an exposed flesh portion, enclosed by fluid-tight films with specific formations such as cuts and ridges to facilitate controlled juice extraction and dispensing, featuring grippable tabs and varying seal strengths to manage opening sizes and directions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If fruit is sliced or cut for juice extraction, then juice can be extracted from the fruit, but wastage occurs if slices are not used within an acceptable timeframe and residue is left on fingers

Engineering Contradiction:
Improvejuice extraction efficiencyVSAvoidfruit wastage
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The fruit segment is pre-packaged in a sealed package before use, with the rind portion already prepared with cuts or openings. This preliminary preparation eliminates the need for slicing at the point of use, preventing wastage while maintaining juice extraction efficiency when the package is squeezed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention uses a disposable sealed package containing the fruit segment. Instead of reusing fruit slices which lead to wastage, a new sealed package is used each time, ensuring no wastage while maintaining consistent juice extraction performance.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Productivity

If fruit slices are squeezed for juice extraction, then juice can be obtained, but the process is messy with residue on fingers and unpredictable juice direction

Engineering Contradiction:
Improvejuice extraction efficiencyVSAvoidmessiness and residue
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The sealed package is made from flexible material that can be squeezed to extract juice. The flexible film contains the fruit segment and directs the juice flow through controlled openings, eliminating messiness and residue on fingers while maintaining extraction efficiency.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The sealed package acts as an intermediary between the fruit and the user. Instead of directly handling fruit slices which cause messiness, the user squeezes the sealed package which contains the fruit, with juice dispensed through controlled openings, eliminating direct contact with residue.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If fruit is used after juice extraction, then the fruit can still be utilized, but the extraction process needs to be controlled to maintain fruit integrity

Engineering Contradiction:
Improvepost-extraction fruit usabilityVSAvoidfruit structural integrity
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The sealed package is designed with specific local features: the rind portion has cuts or openings positioned to allow juice extraction while preserving the flesh portion. This local differentiation enables controlled extraction that maintains the structural integrity of the fruit segment for post-extraction use.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The package is pre-configured with cuts in the rind portion before use, creating a controlled extraction path. This preliminary structuring allows juice to be extracted through the rind openings while the flesh portion remains intact, preserving fruit integrity for subsequent use.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If fruit production is seasonal, then fresh fruit is available, but poor growing seasons lead to shortages and increased prices

Engineering Contradiction:
Improvefruit supply stabilityVSAvoidfruit availability
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The fruit segments are prepared and packaged in advance during periods of abundant supply. This preliminary preparation and storage allow the product to be available during poor growing seasons, stabilizing supply and reducing price fluctuations while maintaining reliable availability.

Inventive Principle:
Principle #10Preliminary action
