Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing red packet payment services lack efficiency and flexibility in their implementation, relying on a preset sequence of logic that does not allow for dynamic state transitions, making maintenance and development cumbersome.
Innovation Solution
Implementing a state machine that adjusts states based on execution results of service logic, enabling a more dynamic and flexible resource data transfer service by executing different service logics corresponding to various states, thereby enriching the implementation and facilitating maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a preset sequence logic is used for resource data transfer service, then the implementation is simple and straightforward, but the service lacks flexibility and adaptability to dynamic conditions
Solution Approach 1:
The patent applies the dynamics principle by introducing a state machine that enables the resource data transfer service to dynamically transition between different states (e.g., waiting state, transferring state, completed state, failed state) based on execution results and external events. This allows the service to adapt to varying conditions rather than following a rigid preset sequence, thereby improving flexibility while maintaining manageable complexity through structured state transitions.
2Adaptability or versatility
If a state machine approach is implemented for resource data transfer service, then the service becomes more flexible and adaptable, but the service logic becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the service logic into distinct, isolated state handlers for each state in the state machine. Each state has its own dedicated logic for handling events and transitions, which makes the complex service logic more manageable, testable, and maintainable. This segmentation reduces the cognitive load of understanding the overall system by allowing developers to focus on individual state behaviors rather than the entire service flow.
Solution Approach 2:
The state machine itself acts as an intermediary that mediates between external events and the underlying resource data transfer logic. Instead of having complex conditional logic scattered throughout the service code, the state machine provides a structured intermediate layer that routes events to appropriate state handlers and manages transitions, thereby organizing complexity in a controlled manner.
3Productivity
If sequential preset logic is used for processing resource data transfer, then the execution flow is straightforward, but the service cannot respond dynamically to different execution results
Solution Approach 1:
The patent implements feedback mechanisms within the state machine where the execution result of each state's service logic feeds back into the state machine, which then determines the next state transition. This feedback loop allows the service to dynamically respond to different execution results (success, failure, partial completion) by transitioning to appropriate states, thereby achieving both efficient execution and adaptive response capability.

AI summary
This application provide a data processing method performed by a computer device. The method includes: receiving a request for a cross-regional resource transfer service submitted by a first user at a first terminal to a second user at a second terminal; setting a state machine of the cross-regional resource transfer service to a first state according to a state identifier in the request; executing a first service logic corresponding to the first state; adjusting the state machine to a second state according to an execution result of the first service logic; executing a second service logic corresponding to the second state; and returning a service execution result of the cross-regional resource transfer service to the first user at the first terminal and the second user at the second terminal according to an execution result of the second service logic when the second state is a termination state.
