Solution Overview

Problem

Existing devices for filling containers with fruit do not allow partial filling and subsequent removal without damaging the fruit, and they require the container to be emptied before reuse.

Innovation Solution

A device comprising a frame with non-parallel tensioning devices that form a net with adjustable openings, allowing fruit to be placed on a support surface that gradually fills the container under its weight, using threads or cords arranged in different planes to prevent damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a tarpaulin is used to support fruit during filling, then the fruit can be handled gently, but the container cannot be reused without emptying it completely

Engineering Contradiction:
Improvefruit damageVSAvoidcontainer reuse flexibility
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The support structure is segmented into multiple independent tensioning devices that can be individually adjusted and released. Each tensioning device controls a portion of the net, allowing the net to be gradually relaxed and removed in segments rather than requiring complete container emptying

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tensioning devices are made dynamically adjustable during the filling process. The net transitions from a taut supporting structure to a relaxed state that can be easily removed, enabling the container to be reused without complete emptying while maintaining fruit safety throughout the process

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the support surface is fixed during filling, then the structure is simple, but the device cannot accommodate partial filling and removal operations

Engineering Contradiction:
Improvesupport structure simplicityVSAvoidpartial filling capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The support surface is transformed from a fixed structure to a dynamically adjustable one through tensioning devices. The net can be tensioned during filling to provide support, then relaxed for removal, enabling partial filling operations without significantly increasing structural complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The tension parameter of the support net is changed during the filling process. By adjusting the tensioning devices, the net transitions between taut and relaxed states, allowing the same simple structure to accommodate different filling scenarios including partial filling and removal operations

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple tensioning devices are used to form an adjustable net, then the fruit handling is gentler and more flexible, but the device complexity increases

Engineering Contradiction:
Improvenet configuration flexibilityVSAvoidnumber of tensioning devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each tensioning device is designed to perform multiple functions: supporting the net during filling, adjusting the net configuration for different fruit types, and facilitating net removal. This multi-functionality reduces the need for additional specialized components, balancing adaptability with device complexity

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