Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current workflow engines have limited functionality, particularly in supporting loop traversal operations and are not user-friendly, as they only allow for simple serial execution of tasks, making it difficult for users without programming experience to implement repetitive tasks.
Innovation Solution
A data processing method that creates an execution instance with a pointing relationship between loop start and end function code blocks, allowing for cyclic execution of a loop function code block based on a loop parameter, enabling users to create workflows with repetitive tasks without needing additional programming experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If workflow engines only support simple serial execution of tasks, then the system complexity is low and ease of operation is maintained, but the functionality is limited and cannot support loop traversal operations
Solution Approach 1:
The workflow engine is segmented into distinct function code blocks including loop start function code blocks, loop end function code blocks, and loop function code blocks. This segmentation allows the system to support loop traversal operations while maintaining clear structural boundaries and manageable complexity through modular design.
2Adaptability or versatility
If workflow engines support loop traversal operations, then the functionality is improved, but the ease of operation deteriorates due to increased programming complexity
Solution Approach 1:
The workflow engine provides self-service capabilities by automatically managing loop traversal operations. Users simply need to configure loop parameters and establish pointing relationships between function code blocks, while the engine handles the iterative execution logic, reducing the programming burden and maintaining ease of operation.
Solution Approach 2:
The loop start function code block and loop end function code block act as intermediaries that encapsulate the complexity of loop traversal. These intermediary components allow users to implement repetitive tasks through visual configuration without needing to understand the underlying iteration mechanics, thus preserving ease of use while enhancing functionality.
3Ease of operation
If users without programming experience need to implement repetitive tasks, then the ease of operation should be high, but the current system lacks the functionality to support such operations
Solution Approach 1:
The workflow engine implements universal loop traversal functionality that can be applied to various repetitive tasks through a standardized interface. The loop start and loop end function code blocks provide multi-functional support for different types of iterations, allowing users without programming experience to implement diverse repetitive operations through a single unified mechanism.
