Solution Overview

Problem

The challenge in electrolytic apparatuses is the difficulty in adjusting operating conditions effectively due to discrepancies between actual and estimated performance changes, leading to inefficiencies in production and power consumption.

Innovation Solution

An operation support apparatus and method that calculates and adjusts operating conditions based on estimated values of performance changes in electrolyzers, using a calculation unit to optimize power consumption, production amounts, and costs, while incorporating estimation units to refine these estimates based on actual values.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If operating conditions are adjusted based on estimated performance change values, then production efficiency can be optimized, but discrepancies between estimated and actual performance values lead to adjustment inaccuracies

Engineering Contradiction:
Improveproduction efficiencyVSAvoidperformance change estimation accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system implements a feedback mechanism where actual performance change values are obtained through measurements, compared with estimated values, and used to correct future estimations. The calculation unit receives both estimated values from the estimation unit and actual values from measurements, then calculates operating conditions based on corrected values that incorporate both prediction and actual performance data, closing the loop between estimation and reality.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The estimation unit performs preliminary estimation of performance changes before actual measurements are available. This allows the system to proactively calculate and recommend operating condition adjustments based on predicted performance trends, enabling advance optimization rather than waiting for actual performance data to become available.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If operating conditions are frequently adjusted to optimize production, then productivity improves, but system complexity and operational difficulty increase

Engineering Contradiction:
Improveproduction amountVSAvoidoperation control complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system performs self-diagnosis and self-optimization by automatically estimating performance changes, calculating optimal operating conditions, and providing adjustment recommendations without requiring complex manual analysis. The calculation unit and estimation unit work autonomously to determine when and how to adjust operations, reducing the burden on operators while maintaining high productivity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system focuses on calculating and adjusting specific operating condition parameters (such as current, voltage, flow rate) based on performance data, rather than requiring comprehensive system reconfiguration. By targeting key parameters for adjustment, the system achieves productivity improvements without proportionally increasing operational complexity.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If operating conditions are adjusted based on actual performance values, then accuracy improves, but response time delays occur due to measurement and data processing

Engineering Contradiction:
Improveperformance change accuracyVSAvoidresponse time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The estimation unit generates predicted performance change values in advance, before actual measurements are completed. This preliminary estimation allows the calculation unit to begin determining optimal operating conditions based on predicted data, reducing the overall response time while maintaining accuracy through subsequent correction with actual measurement values.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from actual measurements to correct and refine operating condition calculations. By continuously comparing estimated versus actual performance values and adjusting future calculations accordingly, the system reduces the need for lengthy measurement-and-wait cycles, as the feedback mechanism progressively improves estimation accuracy over time.

Inventive Principle:
Principle #23Feedback

AI summary

Provided is an operation support apparatus including a calculation unit which calculates an operating condition of an electrolyzer based on a first estimated value of a performance change in electrolytic performance in the electrolyzer. The operation support apparatus may further include an estimation unit which estimates a second estimated value of the performance change based on a first operating condition that is the operating condition calculated by the calculation unit. The calculation unit may calculate, based on the second estimated value, a second operating condition that is the operating condition under which a power consumption amount of the electrolyzer in a predetermined certain period becomes a predetermined power amount or a production amount of a product produced by the electrolyzer in the certain period becomes a predetermined production amount. The operating condition may include a plurality of parameters related to operation of the electrolyzer. The calculation unit may calculate one parameter of the plurality of parameters as the first operating condition, based on the first estimated value.
