A time series data processing device equipped with a first and second processing unit, a control unit for identifying process changes, and a selection unit that appends identification information to results data sets, ensuring that only relevant data is outputted and mixed with the new process results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the old process is stopped immediately when the new process is introduced, then the system can avoid mixing old and new results, but the old process data cannot be fully utilized

Engineering Contradiction:

Improveprocess transition reliabilityVSAvoidold process data utilization

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent introduces a result data set management mechanism that acts as an intermediary between the old and new processes. The selection unit selectively outputs result data sets based on arrival timing, allowing the old process to continue operating and contributing data until its results are no longer needed, thereby fully utilizing old process data while preventing mixing with new process results

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements preliminary actions by maintaining the old process running alongside the new process introduction. The control unit prepares the transition by allowing both processes to operate simultaneously for a transition period, ensuring that old process data is collected and utilized before the old process is eventually stopped, rather than immediately terminating it

Inventive Principle:

Principle #10Preliminary action

2Loss of information

If both old and new processes run simultaneously, then old process data can be fully utilized, but results from old and new processes may be mixed

Engineering Contradiction:

Improveold process data utilizationVSAvoidprocess transition reliability

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The selection unit serves as a mediator that receives result data sets from both old and new processes. It implements a selection criterion based on arrival timing - when result data sets arrive simultaneously, it selectively outputs only one based on predetermined rules. This intermediary mechanism allows both processes to run simultaneously and fully utilize old process data while preventing mixing of results

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements dynamic control of the process transition. The control unit dynamically adjusts the operation state of the old process based on the operational status of the new process and the arrival timing of result data sets. This dynamic management allows flexible switching between processes while maintaining reliability and preventing result mixing

Inventive Principle:

Principle #15Dynamics

3Loss of information

If the old process continues to operate after the new process is introduced, then old process data can be maximally utilized, but the system complexity increases

Engineering Contradiction:

Improveold process data utilizationVSAvoidprocess management complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The control unit and selection unit are designed with multi-functionality to manage both old and new processes simultaneously. The control unit can determine whether to stop or continue the old process based on new process operation status, while the selection unit can selectively output results from either process. This universal design manages the complexity of running multiple processes through integrated control logic

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Device complexity

If the old process is stopped early to simplify management, then system complexity is reduced, but old process data is not fully utilized

Engineering Contradiction:

Improveprocess management complexityVSAvoidold process data utilization

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The patent implements feedback mechanisms where the control unit continuously monitors the operational status of the new process and the arrival timing of result data sets from both processes. Based on this feedback, the control unit dynamically determines when to stop the old process, ensuring that old process data is fully utilized before termination. This feedback-based control simplifies management by providing automatic decision-making criteria rather than requiring complex manual management

Inventive Principle:

Principle #23Feedback

AI summary

Provided is a time series data device with which, when a process is changed, results of both a new and an old process are not outputted to the outside being mixed, and the results of the old process before and after the process is changed can be outputted to the outside. The device is equipped with: a first processing unit that executes a first process and outputs first results data; a second processing unit that executes a second process and outputs second results data; and a control unit that, when an instruction to change a process is received, determines whether the first process can be stopped, and generates first and second results data sets by appending identification information corresponding to process contents to the respective first and second results data.
