Solution Overview

Problem

The existing manufacture work machines face challenges in efficiently generating and transmitting motion commands to multiple work-element performing apparatuses, especially when the manufacturing process is complex and involves a large number of apparatuses, leading to increased trouble and reduced practical utility.

Innovation Solution

A central control device and method that encodes source data in a hierarchical structure to generate motion commands, allowing each command to correspond to a specific motion performed by one work-element performing apparatus, thereby reducing the complexity and effort required for command generation and transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If motion commands are generated for each individual motion of each work-element performing apparatus, then the manufacture work can be controlled in a centralized manner, but the number of motion commands becomes considerably large and the trouble for generating them increases

Engineering Contradiction:
Improvecentralized control capabilityVSAvoidnumber of motion commands
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent combines multiple individual motion commands into a single composite motion command that can control multiple work-element performing apparatuses simultaneously. Instead of generating separate commands for each apparatus, the system merges them into one unified command structure that achieves the same centralized control effect with reduced command quantity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The motion command generating unit creates universal motion commands that can be applied to multiple different work-element performing apparatuses. A single motion command type serves multiple functions across different apparatuses, reducing the overall number of unique commands needed while maintaining centralized control over diverse equipment.

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

2Productivity

If the number of work-element performing apparatuses is increased to handle complex manufacture work, then the productivity improves, but the number of motion commands to be generated increases considerably

Engineering Contradiction:
Improvemanufacture work capabilityVSAvoidtime for generating motion commands
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system merges motion commands for multiple apparatuses into composite commands that can be generated and transmitted as unified units. This reduces the time required for command generation even as the number of apparatuses increases, maintaining productivity without proportionally increasing the time investment for control setup.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The motion commands are designed to be generated in advance as standardized templates that can be reused across multiple apparatuses. By preparing universal command structures beforehand, the system reduces the real-time effort needed for command generation when scaling up the number of work-element performing apparatuses.

Inventive Principle:
Principle #10Preliminary action

AI summary

It is an object to enhance practical utility of a central control device configured to control, in a centralized manner, a plurality of work-element performing apparatuses in a manufacture work machine which is configured to perform a manufacture work by the plurality of work-element performing apparatuses. In a central control device 130, 136 including: a source-data storage section 184 configured to store source data in which is encoded a matter of each of a plurality of work elements to be performed by each of the plurality of work-element performing apparatuses to perform the manufacture work; and a motion-command generating section 188 configured to generate a plurality of motion commands on the basis of the source data, the plurality of motion commands generated by the motion-command generating section are configured to be sequentially transmitted to the plurality of work-element performing apparatuses. In this structure, the source data is made simple by making the most use of techniques of encoding the source data, such as encoding the source data in a hierarchical structure, whereby trouble for generating the motion commands can be reduced so as to enable practical utility of the central control device to be enhanced.
