Solution Overview

Problem

Conventional temporary storage systems face challenges in efficiently storing multiple articles near loading ports due to the need for extended rail lengths, which increases the distance between buffers and loading ports, making it difficult to quickly convey articles to transfer ports.

Innovation Solution

A temporary storage system featuring a grid-patterned travel rail with multiple first and second rails, allowing vehicles to access stop positions above transfer ports and storage locations, enabling efficient transfer and storage of articles without obstructing vehicle travel, and incorporating a transfer part with an elevator for vertical movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the number of buffers is increased, then the storage capacity is improved, but the distance of buffers from the loading port increases, making article conveyance slower

Engineering Contradiction:
Improvenumber of buffersVSAvoidarticle conveyance speed
Core Design Contradiction:
Quantity of substanceVSSpeed

Solution Approach 1:

The patent transitions from a linear rail arrangement to a two-dimensional grid pattern with multiple rails extending in orthogonal directions. This dimensional change allows buffers to be positioned at multiple locations around the loading port, maintaining short distances while increasing storage capacity. The grid structure enables articles to be stored in buffers adjacent to the loading port without requiring long linear extensions.

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

Solution Approach 2:

The vehicle is designed with multi-functional capabilities to operate across the entire grid rail system, accessing both loading ports and buffers from a single transportation network. This universal design allows the same vehicle structure to serve multiple functions: transporting articles between loading ports and buffers, moving articles between different buffers, and adapting to various buffer positions around the loading port without requiring specialized vehicles for different locations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Quantity of substance

If the second rail is extended to increase buffer capacity, then the number of buffers is improved, but the complexity of the rail system increases

Engineering Contradiction:
Improvenumber of buffersVSAvoidrail system complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The rail system is segmented into multiple independent rails extending in orthogonal directions rather than requiring a single long extended rail. Each rail segment can be independently configured and positioned, allowing buffers to be distributed across the grid structure. This segmentation reduces the complexity of any single rail while achieving the same buffer capacity through multiple shorter rails arranged in a two-dimensional pattern.

Inventive Principle:
Principle #1Segmentation

3Speed

If buffers are positioned closer to the loading port for faster conveyance, then the article conveyance speed is improved, but the storage capacity is reduced

Engineering Contradiction:
Improvearticle conveyance speedVSAvoidstorage capacity
Core Design Contradiction:
SpeedVSQuantity of substance

Solution Approach 1:

By transitioning to a two-dimensional grid arrangement with rails extending in multiple directions, the system can position multiple buffers in close proximity to the loading port without requiring them to be arranged linearly. This dimensional expansion allows the system to maintain short conveyance distances while accommodating a larger number of buffers, thereby preserving both fast access and high storage capacity simultaneously.

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