Solution Overview

Problem

Existing automatic conveyance apparatuses face difficulties in moving members between loading surfaces of varying heights and inclinations, particularly in non-flat factory floors, leading to unreliable delivery and pickup operations.

Innovation Solution

An automatic conveyance apparatus equipped with an adjustment device that adjusts the height and inclination of its loading surface to match the second loading surface, combined with a movement device for sliding the member between surfaces, and a control section for coordinated movement, enabling reliable transfer even on uneven factory floors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the height and inclination of the loading surface are kept fixed, then the apparatus structure is simple, but the apparatus cannot adapt to non-flat factory floors or varying loading surface positions

Engineering Contradiction:
Improveadaptability to varying loading surface positionsVSAvoidapparatus structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The loading surface is made dynamically adjustable through the incorporation of an adjustment device that can change the height and inclination of the loading surface in real-time. This allows the automated guided vehicle to adapt to non-flat factory floors and varying loading surface positions, resolving the contradiction between adaptability and structural simplicity.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the loading surface is made adjustable to match varying heights and inclinations, then the apparatus can operate on non-flat floors, but the apparatus configuration becomes more complex

Engineering Contradiction:
Improvereliability of member delivery and pickupVSAvoidapparatus configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The adjustment device enables the loading surface to dynamically adapt its height and inclination to match the second loading surface, ensuring reliable member delivery and pickup operations even on non-flat floors. This dynamic adjustment capability directly improves operational reliability while accepting increased structural complexity.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the loading surface height and inclination are adjusted to match the second loading surface, then member movement becomes reliable, but the adjustment mechanism increases device complexity

Engineering Contradiction:
Improvereliability of member movement between surfacesVSAvoidadjustment mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The adjustment device provides dynamic control over the loading surface's height and inclination, enabling reliable member movement between surfaces by matching their positions. This dynamic adjustment mechanism resolves the contradiction by ensuring operational reliability through active adaptation to varying surface conditions.

Inventive Principle:
Principle #15Dynamics

AI summary

An automatic conveyance apparatus includes a first loading surface, an adjustment device, a movement device, and a control section. The control section drives the movement device to move the member between the first loading surface and the second loading surface when the automatic conveyance apparatus is positioned at a member delivery position and/or a member pickup position where the automatic conveyance apparatus delivers and/or picks up the member and when the height and the inclination of the first loading surface are adjusted in accordance with the height position and the inclination position of the second loading surface by the adjustment device. The automatic conveyance apparatus is configured to travel between multiple predetermined positions including the member delivery position and/or the member pickup position.
