AI Control Input Range Screening for Safer Device Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Control devices using artificial intelligence may perform abnormal control even when the input signal is normal, lacking clarity in processing details and safety assurance.
Innovation Solution
A control device with an input information storage unit to store track record input information, an artificial intelligence control unit for AI-based control, and an input signal evaluation unit that judges whether the input signal is within a predetermined range based on the stored information, allowing only signals within the range to be transmitted to the AI control unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If artificial intelligence is used for control based on input signals, then control flexibility and adaptability are improved, but safety and reliability deteriorate due to unclear processing details and potential abnormal control
Solution Approach 1:
An input signal evaluation unit is introduced as an intermediary between the input signal and the artificial intelligence control unit. This evaluator checks whether the input signal is within a predetermined range before allowing it to reach the AI controller, thereby mediating between the flexible AI control and the need for safety assurance.
Solution Approach 2:
The system performs preliminary evaluation of input signals before they are processed by the artificial intelligence control unit. By checking whether input signals are within expected ranges in advance, the system prevents abnormal control actions from occurring, ensuring safety before the AI control takes effect.
2Reliability
If input signal evaluation is added to check ranges before AI control, then safety is improved, but device complexity increases
Solution Approach 1:
The evaluation mechanism monitors changes in input signal parameters and compares them against predetermined ranges. By focusing on parameter validation rather than complete system redesign, the approach adds safety functionality with minimal increase in overall system complexity.

AI summary
A control device includes: an input information storage unit that stores track record input information that is information regarding an input signal having a track record; an artificial intelligence control unit that controls a control target using artificial intelligence based on the input signal; and an input signal evaluation unit that judges whether a value of the input signal is within a range having a track record based on the track record input information and, if the value of the input signal is within the range having the track record, permits transmission of the input signal to the artificial intelligence control unit. The safety of the control device using artificial intelligence is enhanced.
