Solution Overview
Problem
Existing communication systems for working machines lack efficient methods to activate and execute multiple applications on mobile terminals connected to these machines, particularly for tasks like data collection and engine starting, with inadequate authentication and data transmission protocols.
Innovation Solution
A communication device and system that includes a first communication circuit to transmit application identifiers to a mobile terminal, allowing the terminal to activate a first application and subsequently execute a second application, such as a collecting or starting application, using Bluetooth Low Energy beacons and unique identifiers for authentication and data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple applications are transmitted to the mobile terminal, then the functional capability is improved, but the complexity of application management increases
Solution Approach 1:
The patent segments the application transmission process into distinct phases: first transmitting a first application identifier, activating the first application, then transmitting a second application identifier, and activating the second application. This segmentation breaks down the complex task of managing multiple applications into manageable sequential steps, reducing the perceived complexity while maintaining functional capability.
Solution Approach 2:
The patent employs preliminary action by first transmitting and activating the first application identifier before proceeding to transmit and activate the second application identifier. This preliminary activation ensures that the mobile terminal is properly prepared and authenticated before receiving additional applications, streamlining the overall management process.
2Reliability
If sequential application activation is implemented, then the authentication security is improved, but the time for application execution increases
Solution Approach 1:
The patent performs preliminary authentication and activation actions in the first application phase before proceeding to the second application. This preliminary action establishes security credentials and authentication states that can be reused for subsequent applications, maintaining high security standards while reducing redundant authentication overhead and minimizing total execution time.
