Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machines require cumbersome and time-consuming access methods, posing safety risks and inefficiencies, especially when multiple personnel need to operate or service the machines.
Innovation Solution
Integration of a wireless or contactless reading unit for portable data carriers, such as RFID transponders, for secure and efficient personal access authorization, combined with an alternative manual input option for backup access during failures, and a control unit for managing access rights and locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional key-based locking devices or password-based access systems are used, then basic access control is provided, but the access process becomes time-consuming and cumbersome for multiple personnel
Solution Approach 1:
The patent replaces mechanical key-based locking devices and manual password entry systems with RFID (radio frequency identification) technology. The reading unit wirelessly reads identification data from RFID tags attached to personnel badges, automatically authenticating users without physical key manipulation or manual typing, thereby dramatically reducing access time and operational complexity
Solution Approach 2:
The system enables self-service access where personnel automatically authenticate themselves by simply presenting their RFID badges to the reading unit. The access control system autonomously verifies credentials and activates appropriate locking mechanisms or operating permissions without requiring manual intervention from security personnel or complex authentication procedures
2Productivity
If access control is simplified for quick login, then access speed improves, but security and authorization verification may be compromised
Solution Approach 1:
The patent employs RFID technology with reading units that wirelessly authenticate personnel credentials. The system reads identification data from RFID tags, verifies authorization levels through the control unit, and automatically grants or denies access. This maintains high security through reliable credential verification while achieving rapid access speeds by eliminating manual authentication steps
Solution Approach 2:
The access control system incorporates feedback mechanisms where the reading unit continuously monitors RFID tag presence and validity, the control unit verifies authorization data against stored credentials, and the system provides immediate feedback by activating or deactivating locking devices and operating permissions based on verification results, ensuring both speed and security
3Adaptability or versatility
If manual input devices are used for access control, then flexibility in access methods is maintained, but the process becomes more complex and error-prone
Solution Approach 1:
The patent implements a multi-functional access control system where the reading unit can handle various types of RFID tags and data formats, the control unit can manage different authorization levels and locking mechanisms, and the system supports multiple operating modes (automatic access, manual override, emergency protocols). This universal design provides flexibility for different personnel types and scenarios while maintaining a unified, relatively simple system architecture that reduces operational complexity

AI summary
A packaging machine (1) is proposed, comprising at least one registration device, in particular a login device (13, 16), for verifying personal access authorization. To ensure that registration for access to the packaging machine (1) requires as little time and effort as possible, at least one of the registration devices (13, 16) includes a reading unit for receiving wirelessly and/or contactlessly transmitted information from wirelessly or contactlessly readable portable data carriers (12, 18), as well as an alternative input device for wired input of information. Furthermore, a data carrier is proposed.
