Solution Overview

Problem

Conventional systems that transfer workpieces using robots are limited by the robot's operation region, requiring increased floor space and lacking integration with cranes for efficient transfer and processing, especially when the workpiece needs to be moved outside this region.

Innovation Solution

A robot and crane cooperative work system where the robot can attach or detach the workpiece from the crane, allowing the crane to move it outside the robot's operation region, enabling processing without the need for additional automation equipment, such as conveyor systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a robot transfers the workpiece within its operation region, then the transfer can be performed automatically, but the workpiece cannot be transferred to spots outside the robot's operation region

Engineering Contradiction:
Improveautomatic transfer capabilityVSAvoidtransfer range
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The patent combines the robot and crane into a cooperative work system where the robot handles automatic gripping and positioning while the crane provides extended transport capability. This merging allows the system to achieve both automatic operation and extended transfer range beyond the robot's original operation region.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The crane acts as an intermediary device between the robot and distant workpiece locations. The robot transfers the workpiece to the crane within its operation region, and the crane then transports it to spots outside the robot's operation region, effectively extending the system's versatility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If an automatic conveyor transfer device is used to transfer the workpiece outside the robot's operation region, then the transfer range is extended, but the floor area required increases significantly

Engineering Contradiction:
Improvetransfer rangeVSAvoidfloor area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

Instead of using a horizontal conveyor system that occupies significant floor area, the patent utilizes the vertical dimension by employing a crane that moves along overhead rails. This dimensional change allows extended transfer range without increasing the horizontal footprint of the system.

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

Solution Approach 2:

The crane serves multiple functions: it acts as a transport device for extending the robot's reach, and it can also function as a lifting device for heavy workpieces. This multi-functionality replaces the need for separate conveyor systems, reducing overall floor area requirements.

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

3Extent of automation

If conventional automated transfer systems are implemented, then operator reduction is achieved, but special equipment such as automatic conveyor transfer devices must be provided

Engineering Contradiction:
Improveoperator reductionVSAvoidspecial equipment requirements
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent leverages the existing crane, which is commonly present in industrial facilities, and makes it work cooperatively with the robot. This approach achieves automation benefits without requiring specialized conveyor equipment, thereby reducing device complexity while maintaining operator reduction goals.

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

Solution Approach 2:

The system uses existing infrastructure (the crane) already present in the facility rather than requiring new specialized equipment. This self-service approach allows the robot to achieve extended transfer capability by utilizing resources already available in the work environment.

Inventive Principle:
Principle #25Self-service
