Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single authorization carrier with fixed access authorization is used, then the device structure remains simple, but the device lacks flexibility in managing different operator functions and authorization levels
Solution Approach 1:
The authorization system is segmented into multiple authorization carriers (31, 32, 33), each representing a distinct authorization profile with specific functions. This segmentation allows the system to manage different operator levels without requiring a completely different system architecture, resolving the contradiction between flexibility and complexity by dividing the authorization management into discrete, manageable units.
Solution Approach 2:
The single receptacle (26) is designed to universally accept multiple types of authorization carriers with different authorization profiles. This multi-functionality allows the same physical structure to handle various authorization levels (operator, supervisor, maintenance personnel) without requiring separate receptacles or complex identification mechanisms, thus maintaining structural simplicity while achieving authorization flexibility.
2Reliability
If multiple authorization carriers with different authorization profiles are implemented, then operator functionality and safety are enhanced, but the device structure becomes more complex
Solution Approach 1:
Each authorization carrier (31, 32, 33) is equipped with specific local qualities in the form of identification devices (62, 63, 64) such as color markings or haptic features that correspond to its authorization profile. This local quality differentiation enables the detection unit to reliably distinguish between different authorization levels through simple contact-based detection, enhancing access control reliability without requiring complex identification systems.
Solution Approach 2:
The system uses simplified copies of identification information through optical markings (colors) and haptic features on the authorization carriers. These visual and tactile copies allow operators to quickly identify their authorization level without complex electronic communication or biometric verification, maintaining reliability while minimizing structural complexity.
3Ease of operation
If a single receptacle is used for all authorization carriers, then the device structure remains simple and operation is simplified, but the detection system must handle multiple authorization profiles
Solution Approach 1:
The detection unit replaces complex mechanical or electronic identification systems with simple contact-based detection of optical markings and haptic features. The detection contact elements (47, 48) physically contact the authorization carrier to read its identification, substituting sophisticated detection mechanisms with straightforward mechanical contact that simplifies both the detection process and the overall system structure.
Solution Approach 2:
The system uses color markings (optical identification devices) on the authorization carriers as a simple yet effective method to encode different authorization profiles. The detection unit reads these color codes through contact-based optical detection, enabling easy distinction between different authorization levels without requiring complex electronic communication or mechanical complexity, thus maintaining ease of operation while enabling multi-profile detection.

AI summary
The invention relates to a cleaning device, comprising at least one authorization carrier (28, 29, 30) with an access-authorization means (42, 43, 44) which is stored thereon and is required for access to the cleaning device (10), just one receptacle (26) in which the at least one authorization carrier (28, 29, 30) can be positioned, and a detection unit (58), which is arranged on the receptacle (26), for the contact-associated detection of the access-authorization means (42, 43, 44) of an authorization carrier (28, 29, 30) positioned in the receptacle (26), wherein the detection unit (58) has at least one detection contact element (47, 48) making contact with the access-authorization means (42, 43, 44). In order to provide a cleaning device of this type, which can be used with greater versatility, it is proposed according to the invention that the cleaning device (10) comprises two or more authorization carriers (28, 29, 30) with access-authorization means (42, 43, 44) which are stored thereon and linked to different authorization profiles, wherein a functional scope which is dependent on the authorization profile linked to an access-authorization means (42, 43, 44) can be provided for an operator of the cleaning device (10).
