Solution Overview

Problem

Existing automated container transportation systems require manual intervention for transferring containers between rail systems, which is time-consuming and inefficient.

Innovation Solution

A connection assembly for containers that includes a first and second plate assembly and a release assembly, allowing for quick disassembly and decoupling of containers from the rail system without the need for manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual intervention is used for transferring containers between rail systems, then the transfer process can be completed, but the time and labor required increase significantly

Engineering Contradiction:
Improvetransfer speedVSAvoidmanual handling time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The connection assembly enables automated coupling and decoupling operations through self-actuating mechanisms. The release assembly with spring-loaded rod automatically engages and disengages the connection between first and second plate assemblies without requiring manual intervention, allowing the system to service itself during container transfers.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operations with an automated mechanical system. The release assembly uses spring force to automatically push the rod against stops, creating a self-actuating mechanical system that eliminates the need for human operators to manually connect or disconnect containers from the rail system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If automated connection assembly is used, then transfer efficiency improves, but device complexity increases

Engineering Contradiction:
Improveautomated transfer efficiencyVSAvoidconnection assembly structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The connection assembly is divided into distinct functional segments: first plate assembly with first bearing, second plate assembly with second bearing, and release assembly with rod and spring. Each segment performs a specific function, allowing for modular manufacturing, easier maintenance, and reduced overall complexity compared to a monolithic design.

Inventive Principle:
Principle #1Segmentation

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

Enables efficient and automated transfer of containers between rail systems, reducing the time and labor required for manual handling and improving overall system efficiency.

Implementation Method 1

The spring can be disposed between the extension and the second stop. The release assembly can be configured to occupy: a first state such that the spring pushes the extension against the first stop and thereby biases the first base away from the second base

AI summary

Among other things, a connection assembly for motion along a rail is disclosed. The connection assembly can include a first plate assembly, a second plate assembly, and a release assembly. The first plate assembly can include a first stop mounted to a first base. The second plate assembly can include a second stop mounted to a second base and a post mounted to the second base. The release assembly can include a rod and a spring. The rod can include an outward extension. The spring can be disposed between the extension and the second stop. The release assembly can be configured to occupy: a first state such that the spring pushes the extension against the first stop and thereby biases the first base away from the second base; and a second state such that the spring pushes the extension against the post.
