Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems between intelligent devices and portable terminals, such as mobile phones, lack efficient methods for transmitting toolkit commands to perform maintenance or diagnostic tasks on inaccessible machines, like beverage dispensers or motor vehicles, without a direct man-machine interface.
Innovation Solution
Implementing a wireless interface, preferably NFC, between an intelligent device and a portable terminal, where the intelligent device transmits toolkit commands to a security element, which then relays these commands to the terminal for execution, enabling tasks like displaying information, sending SMS, or launching browser connections, thereby facilitating machine maintenance or diagnosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless interface (NFC) is implemented between intelligent device and portable terminal, then communication capability and ease of operation are improved, but device complexity increases due to additional security element and application layers
Solution Approach 1:
The patent introduces a security element containing a first application as an intermediary component between the intelligent device and portable terminal. This security element acts as a mediator that establishes wireless communication, receives toolkit commands from the intelligent device, and transmits them to the portable terminal for execution. This intermediary approach enables standardized communication protocols and simplifies the interaction model while managing the complexity through a dedicated security layer.
2Adaptability or versatility
If toolkit commands are transmitted through security element to portable terminal, then maintenance and diagnostic capabilities are improved for inaccessible machines, but communication protocol complexity increases
Solution Approach 1:
The patent implements a universal toolkit command structure that can be transmitted through the security element to the portable terminal. This toolkit application layer provides multi-functional capabilities including maintenance tasks, diagnostic operations, and information access for various types of inaccessible machines (beverage dispensers, washing machines, motor vehicles). The standardized toolkit command format enables a single communication framework to handle diverse machine types and operations, enhancing adaptability while managing complexity through standardization.
3Speed
If NFC interface is used for wireless communication, then ease of operation and speed are improved, but manufacturing complexity increases due to integration requirements
Solution Approach 1:
The patent employs a nested architecture where the security element containing the first application is integrated within or associated with the portable terminal, and the toolkit application is embedded within the intelligent device. This nested structure allows the NFC interface to be implemented at multiple levels: the physical NFC hardware layer, the security element layer, and the application layer. This nesting approach enables fast NFC communication while managing manufacturing complexity by organizing components in hierarchical layers that can be developed and integrated independently.
