Solution Overview

Problem

Existing article transport facilities require a large horizontal distance to soften the impact of articles dropped from a transport vehicle, leading to increased facility size.

Innovation Solution

An article transport facility with a transport vehicle that supports articles from below and includes a dropping mechanism, and an article receiving apparatus with a receiving surface disposed higher than the travel surface, allowing for a shortened vertical distance between the supporting and receiving surfaces to soften the impact without increasing horizontal space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a chute sloping downward is used to guide articles from the supporting surface to the receiving surface, then the impact of dropped articles is softened, but a large horizontal distance is required which increases facility size

Engineering Contradiction:
Improveimpact of dropped articlesVSAvoidfacility size
Core Design Contradiction:
Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

The invention transitions from a horizontal chute arrangement to a vertical arrangement by positioning the receiving surface at a higher elevation than the supporting surface. This dimensional change allows the article to travel vertically downward, softening impact through the height difference while eliminating the need for extensive horizontal space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the receiving surface is positioned lower than the supporting surface, then articles can be guided down a chute, but the horizontal distance between transfer means and unloading part must be large

Engineering Contradiction:
Improvearticle guidanceVSAvoidhorizontal distance
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

The invention inverts the conventional arrangement by positioning the receiving surface higher than the supporting surface rather than lower. This inversion allows articles to be guided downward vertically, eliminating the need for long horizontal chutes while maintaining ease of article guidance through gravity-assisted descent.

Inventive Principle:
Principle #13The other way round (Inversion)

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
