Solution Overview

Problem

Existing fruit containers for near-spherical fruits like oranges, tangerines, and apples are not optimized for space efficiency, are not recyclable, and have fixed volumetry that does not adapt to fruit dimensions, making them difficult to carry and open.

Innovation Solution

A container made from a rectangular cardboard or paperboard sheet with folding lines and adhesive areas, featuring a trapezoidal tab for closure and ventilation windows, allowing for adjustable size and easy opening through perforation lines, enabling minimal volume storage and recyclability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If traditional fixed-volume fruit containers are used, then fruit is protected and transported, but the container occupies excessive space and is difficult to carry in a pocket

Engineering Contradiction:
Improvecontainer volumeVSAvoidportability
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The container is divided into a flat laminar structure that can be segmented into different functional zones (base, lateral walls, closing tab) that fold together. This segmentation allows the container to transition from a compact flat state to a three-dimensional form that fits the fruit, resolving the contradiction between small storage volume and adequate fruit protection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The container employs dynamic folding lines and adhesive areas that allow it to transform from a flat two-dimensional sheet into a three-dimensional cylindrical form. This dynamic transformation enables the container to adapt its volume to match the fruit size while maintaining portability in its collapsed state.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If traditional fixed-volume containers are used, then manufacturing is simple, but the container cannot adapt to different fruit dimensions

Engineering Contradiction:
Improveadaptability to fruit dimensionsVSAvoidcontainer structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container structure incorporates folding lines and adhesive areas that enable dynamic transformation from a flat state to a three-dimensional cylindrical form. This allows the same container design to adapt to different fruit diameters by adjusting the degree of rolling and folding, providing versatility without requiring multiple container sizes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The container allows variation in its dimensional parameters (height, diameter, volume) by changing the rolling configuration of the central sector and the positioning of the closing tab. This parameter flexibility enables the container to adapt to different fruit sizes while maintaining a consistent base design.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If traditional containers are used, then they provide basic protection, but they are not recyclable as a whole

Engineering Contradiction:
ImproverecyclabilityVSAvoidmanufacturing process
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The container integrates all functional elements (base, lateral walls, closing mechanism, ventilation) into a single unified laminar structure made from one continuous piece of cardboard or paperboard. This merging of components into a monolithic structure enables the entire container to be recycled together without disassembly, improving recyclability while keeping the manufacturing process simple through die-cutting and folding.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of operation

If a closed container structure is used, then fruit is protected, but the container is difficult to open

Engineering Contradiction:
Improveease of openingVSAvoidcontainer closure
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The closing tab is connected to the main body through a perforated separation line, creating a segmented structure where the tab can be easily detached by pulling. This segmentation maintains the strength of the closed container while enabling easy opening through simple manual separation at the perforated line.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The perforation lines are pre-formed during manufacturing, creating predetermined weak points that guide the opening action. This preliminary preparation of separation lines allows the user to open the container easily by simply pulling the closing tab, without requiring tools or complex opening mechanisms.

Inventive Principle:
Principle #10Preliminary action
