Solution Overview

Problem

Existing collection containers for fruits like apples are cumbersome to assemble and manufacture, requiring elaborate designs with multiple wire straps and hubs, making them laborious and costly to produce and use.

Innovation Solution

A collection container composed of structurally identical shell segments that can be assembled to form a full shell, allowing for simplified and cost-effective manufacturing and operation, with a pivotable design that uses elastic deformation to collect objects by rolling over them.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a collection container is made from multiple wire straps and hubs, then the container can collect fruits by elastic deformation, but the manufacture and assembly become elaborate and laborious

Engineering Contradiction:
Improvefruit collection functionVSAvoidmanufacture and assembly simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The collection container is divided into multiple identical shell segments (e.g., 4 segments for a full shell), each defining a specific dihedral angle. Each segment is a self-contained unit that can be manufactured independently and then assembled by connecting corresponding connector interfaces, greatly simplifying both manufacturing and assembly processes while maintaining the elastic deformation function for fruit collection

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the structural parameters from traditional wire strap assemblies to molded shell segments with integrated connector interfaces. This parameter change allows the container to maintain its functional properties (elastic deformation for collecting) while dramatically simplifying manufacturing through molding processes and assembly through interface coupling

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If a collection container uses a traditional wire strap design, then it can achieve the necessary flexibility for collecting fruits, but the device complexity increases

Engineering Contradiction:
Improveflexibility for fruit collectionVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into the shell segment structure: the segment itself provides the elastic deformation capability for fruit collection, while integrated connector interfaces enable simple assembly. This merging reduces device complexity by eliminating separate wire straps, hubs, and multiple fastening components that would otherwise be needed

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Each shell segment is designed as a universal component that can be used in different configurations (e.g., 4 segments for a full shell, 2 segments for a half shell). The segments maintain the flexibility needed for fruit collection while their standardized interfaces allow them to serve multiple assembly configurations, reducing overall device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The modular design significantly reduces assembly effort and manufacturing costs, enabling easy and efficient collection of objects like fruits by rolling the container over them, while maintaining flexibility for different designs and adaptations.

Implementation Method 1

By rolling the collection container over a fruit lying on the ground, the wires where the fruit touches the basket are spread apart by the fruit such that the fruit can enter the container through the basket envelope

AI summary

The present application in particular is directed to a collection container (3) configured to be pivotable around a pivot axis (P) and operable to pick up objects (23), such as fruits, by rolling it over the objects (23) in a pivoting movement to thereby pass the objects (23) through the outer shell into the collection container (3), wherein, the collection container (3) comprises an outer shell that is assembled from a predefined number of collection container shell segments (10), each shell segment defining a predefined angular sector of the outer shell.
