Solution Overview
Problem
Conventional space cleaning devices fail to accurately detect the input of an electrolysis accelerator, leading to excessive generation of hypochlorous acid in electrolyzed water, which can exceed reference values.
Innovation Solution
A space cleaning device with an input detector and non-input detection number counter that adjusts the electric conduction time for electrolysis based on the number of undetected input attempts, ensuring the concentration of hypochlorous acid remains within safe limits by shortening the electric conduction time when multiple input failures occur.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the light emitter and light receiver are disposed across the input path to detect electrolysis accelerator input, then the input detection function is provided, but detection failures may occur leading to excessive hypochlorous acid concentration
Solution Approach 1:
The system implements feedback control by continuously monitoring the light receiver signal and comparing it against expected values. When detection failures are suspected, the control unit adjusts the electrolysis conditions based on feedback from multiple sensors (light receiver, concentration sensors) to prevent excessive hypochlorous acid generation while maintaining reliable operation
Solution Approach 2:
The system changes operational parameters dynamically by adjusting electrolysis current, voltage, or time based on light receiver signal quality and detection confidence. When detection reliability is compromised, the system modifies electrolysis parameters to prevent over-generation of hypochlorous acid, thus resolving the contradiction between detection precision and concentration control reliability
2Reliability
If the electrolysis accelerator input is instructed again when input is not detected, then the input reliability is improved, but the hypochlorous acid concentration may exceed reference values
Solution Approach 1:
The system dynamically adjusts electrolysis conditions based on real-time detection status and operational history. When repeated input instructions are given due to detection failures, the control unit dynamically reduces electrolysis intensity or duration to prevent cumulative excess hypochlorous acid generation, while still maintaining reliable accelerator input functionality
Solution Approach 2:
The system applies partial action by giving up on complete input detection reliability in favor of controlled electrolysis. When detection failures occur, the system intentionally limits electrolysis output to partial levels rather than full capacity, preventing excessive hypochlorous acid concentration even if accelerator input is not perfectly detected
3Productivity
If the electric conduction time is extended to ensure complete electrolysis, then the electrolysis efficiency is improved, but the hypochlorous acid concentration becomes excessively high
Solution Approach 1:
The system uses periodic action by implementing intermittent electrolysis cycles with adjustable durations. Instead of continuous extended electrolysis, the system performs multiple shorter electrolysis periods with monitoring intervals, maintaining high productivity while preventing excessive hypochlorous acid accumulation through periodic assessment and adjustment
