Cleaning Appliance RFID Access Profiles With Visual Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning appliances require access authorization to prevent improper operation, but the process can be cumbersome and require mechanical detection, which complicates user-friendly access control.
Innovation Solution
The cleaning appliance uses multiple authorization carriers with different authorization profiles linked to access authorizations, each equipped with identification devices perceivable by sensory organs such as vision or touch, allowing operators to easily determine the profile without activating the appliance, and employs RFID technology for contactless access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical detection methods are used for access authorization, then access control is achieved, but the operation becomes cumbersome and user-unfriendly
Solution Approach 1:
The patent replaces mechanical detection methods with RFID (radio frequency identification) technology. The authorization carrier contains an RFID transponder that communicates wirelessly with the cleaning appliance's reader, eliminating the need for mechanical insertion or contact-based detection. This substitution maintains secure access control while dramatically improving ease of operation, as users can simply present their authorization card without physical manipulation.
2Adaptability or versatility
If multiple authorization carriers with different profiles are used, then functional access control is improved, but the complexity of the access control system increases
Solution Approach 1:
The patent segments the authorization system into multiple authorization carriers, each with a specific authorization profile (e.g., operator, maintenance personnel, supervisor). Each carrier contains segmented information about the user's permissions and identity. The cleaning appliance's control unit reads these segmented profiles and grants appropriate access to different functions, thereby achieving versatile functional access control without requiring a monolithic complex system.
Solution Approach 2:
The patent uses RFID technology to create wireless copies of authorization information. Instead of requiring physical contact or complex mechanical verification, the system reads authorization profiles wirelessly from the carrier's transponder. This copying mechanism simplifies the interaction between the authorization carrier and the cleaning appliance, reducing the perceived complexity for the user while maintaining multiple authorization profiles.
3Reliability
If authorization profiles determine the range of functions, then proper access control is achieved, but the risk of misidentification increases
Solution Approach 1:
The patent incorporates a feedback mechanism where the cleaning appliance's control unit reads the authorization profile from the RFID transponder and provides visual feedback through a display unit. The display shows information about the detected authorization profile, allowing the user to verify that the correct carrier is being used. This feedback loop prevents misidentification by giving immediate visual confirmation of the authorization level being accessed.
Solution Approach 2:
The patent uses color-coded visual indicators (such as colored rings or display elements) to represent different authorization profiles. For example, different colors may indicate operator, maintenance, or supervisor levels. This visual color-coding system provides immediate, intuitive identification of the authorization profile, eliminating confusion and preventing misidentification of the correct authorization carrier.

AI summary
The invention relates to a cleaning appliance, wherein in order to access same, an access authorization stored on an authorization carrier is required, the appliance including two or more authorization carriers with access authorizations stored thereon which are linked to different authorization profiles, and a detection unit for detecting the access authorization of an authorization carrier, wherein a range of functions dependent on the authorization profile linked to the access authorization can be provided to an operator by the cleaning appliance. In order to provide such a cleaning appliance which is more user-friendly in operation, it is proposed that each authorization carrier comprises an identification device for providing an identifier which is associated with the particular authorization profile of the authorization carrier and which is perceivable by the operator using a sensory organ, wherein identifiers associated with different authorization profiles are different from one another.
