Method for diagnosing ice-making apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an effective method to diagnose the operational state of ice-making apparatuses, particularly to determine if they are functioning normally after inspection and repair, as existing methods lack efficiency in assessing the number of ice forming and removing cycles and cycle times.
Innovation Solution
A method involving a control unit and display unit that determines the satisfaction of diagnosis-initiation conditions, counts the number of ice forming and removing cycles, and displays the results, including the actual cycle times, to assess the normal or abnormal state of the apparatus.

Engineering Contradiction Analysis
1Productivity
If manual inspection and repair methods are used for ice-making apparatus, then operational state assessment becomes complex and time-consuming, but existing diagnostic methods lack efficiency in assessing cycle counts and times
Solution Approach 1:
The control unit automatically counts ice forming and removing cycles and measures cycle times in advance, storing this data for later diagnostic comparison. This preliminary data collection eliminates the need for manual counting and assessment during actual diagnostics, significantly improving diagnostic efficiency while reducing the time operators need to spend on assessments.
Solution Approach 2:
The system compares actual cycle counts and times against pre-stored normal operation data, providing automated feedback on whether the apparatus is operating normally. This feedback mechanism eliminates manual assessment of operational state, allowing operators to quickly determine if the ice-making apparatus is functioning within acceptable parameters without time-consuming manual measurements.
2Measurement precision
If detailed cycle monitoring is implemented to accurately determine operational state, then measurement precision improves, but device complexity increases
Solution Approach 1:
The control unit automatically performs cycle counting and time measurement without requiring external monitoring devices or complex diagnostic equipment. The existing control unit repurposes its own capabilities to conduct self-diagnosis, achieving precise cycle monitoring while avoiding additional device complexity. The system serves itself by using its built-in control functions to monitor and assess its operational state.
3Reliability
If automated cycle counting is implemented to improve diagnostic accuracy, then reliability of operation assessment improves, but ease of operation decreases due to additional control functions
Solution Approach 1:
The control unit performs multiple functions: it controls the ice-making cycles, counts the cycles, measures cycle times, and conducts diagnostic comparisons. By making the control unit universal and multi-functional, the system achieves reliable automated diagnostics without adding separate control devices that would complicate operation. The existing control interface handles both normal operation and diagnostic functions, maintaining ease of operation while improving reliability.
