Wireless Blockade Element for Loaned Item Issuance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for issuing and returning loaned items, such as transport trolleys, often require manual effort and may not adequately prevent unauthorized use or incentivize timely return, especially when customers lack a deposit or separate identification means.
Innovation Solution
A method utilizing mobile communication technology for wireless communication between a mobile device and a blockade element attached to the loaned item, allowing for simplified issuance and return by linking and unlinking the device to the item via wireless technologies like Bluetooth or NFC, which can also integrate with existing deposit locks or electronic locks for secure release and return.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual issuance and return processes are used for loaned items, then the system is simple to implement, but the ease of operation deteriorates and manual effort increases
Solution Approach 1:
The patent replaces manual mechanical operations with wireless communication technology. The blockade element communicates wirelessly with a mobile device to transfer identification and release information, eliminating the need for manual key insertion, code entry, or physical interaction with complex mechanical systems. This substitution significantly improves ease of operation while maintaining manageable system complexity through standardized wireless protocols.
Solution Approach 2:
The patent introduces a wireless communication interface as an intermediary between the blockade element and the user's mobile device. This intermediary enables automatic identification and release operations without direct manual intervention, allowing the system to leverage existing mobile device capabilities (processors, displays, wireless interfaces) to simplify the user interaction process.
2Reliability
If deposit systems are used for trolleys, then unauthorized taking is prevented, but the ease of operation worsens and requires separate identification means
Solution Approach 1:
The patent makes the mobile device universal by using it for multiple functions: identification, deposit verification, and release authorization. Instead of requiring separate identification cards, physical deposits, and mechanical keys, the single mobile device performs all these functions through wireless communication with the blockade element, thereby improving ease of operation while maintaining security through the integrated multi-functional approach.
Solution Approach 2:
The patent merges the identification function, deposit verification function, and release authorization function into a single integrated process. The mobile device contains or accesses all necessary information (identification data, deposit status, release codes) and communicates with the blockade element to execute all operations simultaneously, eliminating the need for separate identification means and simplifying the user experience.
3Ease of operation
If mobile communication technology is used for issuance and return, then ease of operation improves, but device complexity increases
Solution Approach 1:
The patent uses wireless communication to create a digital copy of the identification and release process. Instead of requiring physical interaction with complex mechanical systems, the system creates and transmits digital representations of identification data and release instructions through wireless signals, simplifying the user interface while managing complexity through software-based solutions.
Solution Approach 2:
The system leverages the mobile device's existing capabilities (processor, display, wireless interface, database) to perform the issuance and return operations. The mobile device serves itself by using its built-in resources to communicate with the blockade element, eliminating the need for specialized hardware on the loaned item and reducing overall system complexity while maintaining high ease of operation.

AI summary
A method for issuing and returning an item for loan, particularly a manually movable transport cart. A blocking element allows removal and use of the item by way of a release and, after a return, once more prevents the removal. A mobile communication device identifies itself to the blocking element wirelessly, the mobile communication device is associated with the item for loan when the item is released, and the association is cancelled when the item is returned. An issuing and return system has the blocking element attached to the item for loan, in particular is integrated in the item. The blocking element has a communication module for wireless communication with the mobile communication device of a customer. The mobile communication device has an identification feature, particularly a feature that personalizes the customer and which enables the association between the mobile communication device and the item for loan.
