Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwasher temperature monitoring systems are inefficient as they require manual labor for temperature recording and lack data logging capabilities, making them susceptible to errors and fraudulent reporting, and do not allow for historical analysis.
Innovation Solution
A dishwasher thermometer with a wireless temperature logger that includes a processor, temperature sensor, and memory to automatically log and transmit maximum and minimum temperatures during the wash cycle, with features like initiation and cycle end signals, alerts, and data storage for remote access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual temperature recording with strip thermometers or LCD screens is used, then device complexity is reduced, but productivity decreases due to manual labor requirements and data transcription
Solution Approach 1:
The temperature monitoring system performs automatic data logging and wireless transmission without requiring manual intervention. The processor automatically captures temperature data from the sensor, stores it in memory, and transmits it to remote devices, eliminating the need for employees to manually record and transcribe temperature readings.
Solution Approach 2:
The patent replaces manual mechanical recording processes with electronic automation. Instead of physically writing down readings from strip thermometers or LCD screens, the system uses a processor to automatically capture, store, and wirelessly transmit temperature data, substituting human labor with electronic systems.
2Reliability
If manual recording methods are used, then device complexity is lower, but reliability decreases due to susceptibility to fraudulent reporting and errors
Solution Approach 1:
The system provides automatic feedback by continuously monitoring temperature and immediately transmitting data to remote devices. This real-time feedback loop eliminates delays and opportunities for manual manipulation, ensuring that temperature data is accurately recorded and reported without human intervention.
Solution Approach 2:
The temperature monitoring system serves itself by automatically capturing, validating, storing, and transmitting temperature data without requiring human verification or transcription, thereby eliminating errors and fraudulent reporting associated with manual processes.
3Loss of information
If traditional temperature monitoring systems are used, then manufacturing precision requirements are reduced, but loss of information occurs due to lack of data logging capabilities
Solution Approach 1:
The system performs preliminary data logging by continuously capturing and storing temperature readings in memory during the wash cycle. This preliminary action ensures that temperature data is preserved and available for later analysis, compliance verification, and historical tracking without requiring additional manual data collection efforts.
4Loss of time
If manual temperature recording is used, then ease of operation is maintained, but loss of time occurs due to manual data transcription to spreadsheets
Solution Approach 1:
The patent replaces the mechanical process of manual data transcription with automatic electronic data transmission. The processor wirelessly transmits temperature data directly to remote devices or databases, eliminating the time-consuming manual process of copying data from LCD screens or strip thermometers to spreadsheets.

Data Source
AI summary
A dishwasher thermometer captures temperature data of temperature sensed within a dishwasher during a wash cycle. The dishwasher thermometer includes a wireless communication interface that transmits the captured temperature data to one or more of a server and a monitor device. When the captured temperature data indicates that the wash cycle did not achieve defined temperature threshold(s), an alert is generated at the server and/or the monitor device indicating that the wash cycle did not meet appropriate washing conditions. In embodiments, the temperature data may be accessible to a third party for certification of the dishwasher wash cycle.
