Solution Overview

Problem

The existing methods for handling bars in the construction industry are complex and time-consuming, requiring bridge cranes and manual operation to switch between different types of bars, leading to machine downtimes and inefficiencies in supplying bars to user machines.

Innovation Solution

An apparatus with a support plane and movement devices that allows for the storage and distribution of multiple types of bars, enabling automated handling and delivery to user machines without the need for bridge cranes, using a system of movement units and transfer arms to manage bar distribution and positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If bridge cranes and manual operations are used to switch between different types of bars, then bars can be removed from stores and delivered to feed stations, but the process becomes complex and time-consuming, leading to machine downtimes

Engineering Contradiction:
Improvebar supply efficiencyVSAvoidmachine downtime
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system pre-positions multiple bundles of different bar types on the support plane before they are needed. The movement device advances bundles toward the feed station in advance, so when a bar type change is needed, the next bundle is already in position and can be quickly transferred, eliminating machine downtime.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The support plane acts as an intermediary buffer between the store and the feed station. It temporarily holds multiple bundles of different bar types, allowing the feed station to receive bars continuously without waiting for bridge crane operations to transfer bundles from the store.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If dedicated structures and operators are used to guide and position bars from store to work plane, then bars can be transferred, but the procedure becomes extremely complex

Engineering Contradiction:
Improvebar transfer operationVSAvoidtransfer structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The movement device automatically advances bundles from the store onto the support plane without requiring operators to manually guide and position them. The system performs the positioning function itself through automated movement, eliminating the need for dedicated guiding structures and manual intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention extracts the complex manual guiding and positioning operations from the transfer process. By removing the need for operators to suitably guide and position bars, the system simplifies the operation while maintaining effective bar transfer capability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If bundles of bars are removed and replaced from stores using bridge cranes, then different types of bars can be supplied to user machines, but the cycle is time-consuming and causes machine downtimes

Engineering Contradiction:
Improvebar type switching capabilityVSAvoidbar supply rate
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

Multiple bundles of different bar types are pre-loaded onto the support plane in advance. When the feed station needs to switch from one bar type to another, the next required bundle is already positioned and ready for immediate transfer, enabling rapid bar type switching without stopping the user machine.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The support plane maintains a continuous supply of different bar types, allowing the feed station to operate continuously without interruption. While one bundle is being fed to the user machine, other bundles are already in position on the support plane, ensuring uninterrupted bar supply regardless of type changes needed.

Inventive Principle:
Principle #20Continuity of useful action
