Solution Overview

Problem

Existing transport vehicles struggle to stably hold and transport open-type containers with obliquely upward openings, as their support surfaces are not designed to accommodate tilting configurations, leading to instability during transport.

Innovation Solution

A transport vehicle equipped with a holding device featuring inclined support and pressing surfaces that adjust posture to securely hold containers with obliquely oriented openings, ensuring stable support from both upper and lower sides.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If horizontal support surfaces are used in the holding device, then the container can be held in a conventional upright position, but the container cannot be stably held when tilted with the opening facing obliquely upward

Engineering Contradiction:

Improveability to hold container in tilted positionVSAvoidstability of holding

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The support surfaces are designed to be inclined rather than horizontal, allowing the holding device to adapt to tilted container positions. The inclined support surface and inclined pressing surface work together to maintain stable holding when the container is tilted with its opening facing obliquely upward, resolving the contradiction between adaptability to tilted positions and holding stability.

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If the container is transported with the opening facing obliquely upward to prevent objects from flying out, then safety is improved, but existing holding devices cannot stably support this configuration

Engineering Contradiction:

Improveprevention of objects from flying outVSAvoidstability of transport

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The holding device employs asymmetric inclined surfaces instead of symmetric horizontal surfaces. The inclined support surface and inclined pressing surface are designed at specific angles to accommodate the oblique orientation of the container opening, enabling stable transport while preventing objects from flying out during movement.

Inventive Principle:

Principle #4Asymmetry

3Stability of the object's composition

If inclined support surfaces are used to hold the container, then the container can be supported in an oblique posture, but the pressing force may not be effectively applied to the pressed portion

Engineering Contradiction:

Improveposture stability of containerVSAvoidpressing force effectiveness

Core Design Contradiction:

Stability of the object's compositionVSForce

Solution Approach 1:

The pressing surface is designed with the same inclination angle as the support surface, creating a parallel configuration. This parameter change ensures that when the inclined support surface holds the container in an oblique posture, the inclined pressing surface can effectively apply pressing force to the pressed portion in a direction orthogonal to the inclined surface, maintaining both posture stability and effective pressing force application.
