Solution Overview

Problem

Developing custom automation and process control software for hardware devices is time-consuming and costly, with coordination among multiple developers with different expertise being difficult due to asynchronous contributions.

Innovation Solution

A function block framework is introduced that enables multiple developers to contribute to the development of executable code for hardware devices, allowing for rapid and efficient development by providing a standardized framework for generating and testing executable images, which separates function block development from core development and facilitates sharing of code among developers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If custom automation software is developed manually by multiple developers, then functionality can be customized, but development time and cost increase significantly

Engineering Contradiction:
Improvesoftware customizationVSAvoiddevelopment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The software is segmented into reusable function blocks that can be independently developed, tested, and combined. Each function block represents a modular unit of automation functionality that can be assembled to create customized solutions without developing entire systems from scratch.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system allows customization through parameter configuration of standardized function blocks rather than custom code development. Developers can adapt software behavior by modifying parameters and configurations of existing blocks, enabling rapid customization without increasing development time.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If multiple developers work asynchronously on software components, then parallel development is enabled, but coordination difficulty increases

Engineering Contradiction:
Improveparallel developmentVSAvoidcoordination complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

By dividing the software into standardized function blocks, each developer can work on specific blocks independently with clear interfaces defined by the framework. This segmentation enables parallel development while reducing coordination complexity through standardized interaction protocols.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The function block framework provides universal interfaces and standards that work across all development teams. This universality allows developers from different expertise areas to contribute using common patterns and conventions, simplifying integration and coordination.

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

3Reliability

If comprehensive software testing is performed, then bug reduction is achieved, but development time increases

Engineering Contradiction:
Improvebug reductionVSAvoidtesting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Testing is performed preliminarily at the function block level before integration into the complete system. Each function block is validated independently through automated tests, ensuring bugs are caught early in the development process rather than during final system testing, thus reducing overall testing time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The testing process is segmented to match the modular function block structure. Independent test suites can be executed for each block, allowing parallel testing and reducing the total time required compared to testing the entire system as a single unit.

Inventive Principle:
Principle #1Segmentation
