Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional packaging containers with elongated shapes are not suitable for compressing, storing, and unloading springs due to the springs' tendency to reset and spring out of the open end, making controlled unloading impossible.

Innovation Solution

A packaging container unit with an elongated box body featuring a side-mounted second opening for unloading springs, which is perpendicular to the longitudinal axis, and equipped with one or more one-way toggle pieces on the bottom surface to prevent springs from escaping during loading and unloading.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If springs are loaded into an elongated packaging container and compressed, then packaging space is saved, but the compressed springs tend to reset initial lengths and spring out of the open end, making controlled unloading impossible

Engineering Contradiction:

Improvepackaging spaceVSAvoidcontrolled unloading

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The packaging container is divided into two distinct openings: a first opening at the bottom for loading springs and a second opening at the top for unloading springs. This segmentation allows independent control of loading and unloading operations, preventing springs from springing out during compression while enabling controlled unloading through the top opening.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The unloading opening is positioned at the top end of the elongated container, perpendicular to the longitudinal axis, rather than at the same end as the loading opening. This dimensional change in opening positioning creates separate access paths for loading and unloading, eliminating the conflict between compression and unloading operations.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Force

If traditional packaging containers with closed ends are used, then springs can be compressed, but additional pressure is needed to close the packaging barrels and lids must be opened to unload the springs

Engineering Contradiction:

Improvecompression forceVSAvoidlid structure

Core Design Contradiction:

ForceVSDevice complexity

Solution Approach 1:

The lid structure is extracted and replaced with an open top design. The packaging container has a bottom opening for loading and a top opening for unloading, eliminating the need for lids and reducing the complexity of closing and opening operations while maintaining compression capability.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of operation

If the packaging container has an open end for loading, then springs can be easily loaded, but the springs will directly spring out of the open end when compressed

Engineering Contradiction:

Improveloading operationVSAvoidspring containment

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The container is segmented with separate openings for loading and unloading: the bottom opening allows spring insertion while the top opening provides a controlled exit path. This segmentation prevents springs from springing out the loading opening during compression while maintaining easy loading access.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The top opening acts as an intermediary exit path for spring unloading. Instead of springs directly springing out the loading opening, they are controlled to exit through the top opening, providing a mediator path that enables reliable containment during compression.

Inventive Principle:

Principle #24Intermediary (Mediator)

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 solution allows for controlled unloading of springs by preventing them from easily springing out due to the elastic force, and ensures secure loading and storage by preventing reverse deformation of the one-way toggle pieces.

Implementation Method 1

one or more one-way toggle pieces extending toward an inner side of the box body to have merely forward deformation of the one or more one-way toggle pieces instead of reverse deformation

Methodology Applied

Scientific EffectElastic deformation: Elasticity

Implementation Method 2

A direction of an elastic force of the springs is primarily upward or downward along a longitudinal axis of the box body

Methodology Applied

Scientific EffectElastic force: Elasticity
