Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Double feeding of transporting targets occurs when they are loaded on a horizontal loading surface and fed along the same direction due to the weight of the targets.

Innovation Solution

A loading portion is disposed on the downstream side of the transporting path and loads the targets on an inclined surface, while a feeding unit feeds the targets obliquely upward along this surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the loading surface is disposed along the horizontal direction, then the transporting target can be easily loaded, but double feeding occurs due to the weight of the transporting target acting in the load direction

Engineering Contradiction:
Improveloading easeVSAvoidfeeding accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The loading surface is changed from horizontal to inclined, introducing a dimensional change in the orientation of the loading surface. This inclination angle causes the weight of the transporting target to act in a direction that does not promote double feeding, while still allowing easy loading operation.

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

2Device complexity

If the feeding unit feeds the transporting target along the horizontal direction, then the feeding process is simple, but double feeding and feeding failures occur

Engineering Contradiction:
Improvefeeding mechanism complexityVSAvoidfeeding reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The inclined loading surface creates a gravitational component that acts against the feeding direction. This gravitational force component counteracts the tendency for double feeding, providing a natural counterweight effect that improves feeding reliability without complicating the feeding mechanism.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

AI summary

A feeding device includes: a loading portion that is disposed on a downstream side of a transporting path in a transporting direction and that loads a transporting target, which is transported through the transporting path, on a loading surface inclined with respect to a horizontal direction; and a feeding unit that feeds the transporting target, which is in contact with the loading surface, obliquely upward along the loading surface.
