Solution Overview
Problem
Current cleaning devices require complex authorization profile determination, often necessitating device operation to verify authorization carriers, which complicates user-friendly operation and increases the risk of incorrect operation.
Innovation Solution
The cleaning device employs identification devices such as optical, haptic, and acoustic markers on authorization carriers to easily determine the linked authorization profile, allowing for contactless access control using RFID technology and a display device for user-friendly identification and authorization confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access authorization is controlled using authorization carriers with different authorization profiles, then security and proper authorization are improved, but the complexity of determining the authorization profile increases
Solution Approach 1:
The patent applies preliminary action by providing visual identification (color coding, symbols, or text) on the authorization carrier that allows the operator to determine the authorization profile before inserting it into the cleaning device. This pre-display of authorization information eliminates the need to operate the device to verify the profile, thus reducing complexity while maintaining security.
2Measurement precision
If device operation is required to verify authorization profiles, then accurate authorization determination is improved, but ease of operation deteriorates
Solution Approach 1:
The patent introduces an intermediary element - visual identification markers (such as color codes, symbols, or text displays) on the authorization carrier that mediate between the authorization profile and the operator. This intermediary provides immediate visual feedback about the authorization profile without requiring device operation, thus improving ease of operation while maintaining verification accuracy.
3Adaptability or versatility
If multiple authorization carriers with different profiles are used, then functional versatility is improved, but the difficulty of identifying the correct carrier increases
Solution Approach 1:
The patent applies local quality by providing distinct visual characteristics (different colors, symbols, or text) at specific locations on each authorization carrier that correspond to its authorization profile. This localized visual information makes it easy to distinguish between different authorization carriers and identify the correct one for the required function, thus reducing identification difficulty while maintaining versatility.

AI summary
The invention relates to a cleaning device, wherein in order to access same, an access authorization stored on an authorization carrier (32, 36, 37; 52, 53, 54) is required, comprising two or more authorization carriers (32, 36, 37; 52, 53, 54) having access authorizations stored thereon, said authorizations being linked to different authorization profiles, and a detecting unit (27) for detecting the access authorization of an authorization carrier (32, 36, 37; 52, 53, 54), wherein a scope of functions dependent on the authorization profile linked to the access authorization can be provided to an operator of the cleaning device (10). In order to provide such a cleaning device, the operation of which is more user-friendly, each authorization carrier (32, 36, 37; 52, 53, 54) comprises an identification device (42, 43, 44; 61, 62, 63) for providing an identifier (45, 46, 47; 64, 65, 66) associated with each authorization profile of the authorization carrier (32, 36, 37; 52, 53, 54) and detectable by the operator using a sensory organ, wherein identifiers (45, 46, 47; 64, 65, 66) associated with different authorization profiles are different from each other.
