Method for a data communication with a cleaning and/or disinfection machine, method for carrying out a function test of a cleaning and/or disinfection machine, and cleaning and/or disinfection machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for maintaining and testing cleaning and disinfection machines, such as dishwashers and bedpan washers, require separate reading devices and complex data interfaces, which can be cumbersome and insecure, especially in multi-machine environments where regular functionality checks are crucial.
Innovation Solution
Implementing a method that uses graphic codes, such as 2D codes, displayed on the machine's display panel for data communication, allowing commercially available devices like smartphones to read and decode the data, reducing the need for additional interfaces and enhancing security through unidirectional optical communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate reading devices and complex data interfaces are used for data communication with cleaning and disinfection machines, then data transmission can be achieved, but the setup effort increases and security is compromised
Solution Approach 1:
The patent extracts the data communication function from complex wired interfaces and separate reading devices, and embeds it directly into the display panel through graphic code generation. This eliminates the need for separate communication hardware and reduces interface complexity while maintaining security through unidirectional optical communication.
Solution Approach 2:
The display panel is given a dual function: it serves both as the user interface for displaying machine status and as a data communication interface by generating graphic codes that can be read by any smartphone or camera-equipped device. This universal approach eliminates the need for machine-specific reading devices.
2Ease of operation
If commercially available devices like smartphones are used to read data, then setup effort is reduced and accessibility is improved, but separate reading devices were previously required
Solution Approach 1:
The display panel generates graphic codes in a universal format (such as QR codes or other machine-readable visual formats) that can be decoded by any smartphone, tablet, or camera-equipped device. This eliminates the need for proprietary reading devices and significantly reduces setup effort, as users can simply use their existing mobile devices to scan and access machine data.
3Reliability
If optical graphic code interface is used for data communication, then unidirectional communication and security are enhanced, but data transmission capability must be maintained
Solution Approach 1:
The patent creates a visual copy of the machine data in the form of graphic codes displayed on the screen. This optical copy contains all necessary information (error codes, usage data, machine status) in a format that can be accurately captured and transmitted without loss, while the unidirectional nature of optical display ensures security by preventing unauthorized writing or interference.
