Mobile Work Machine Diagnostic Software Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for diagnosing errors in mobile work machines require service technicians to manage multiple software versions and types, leading to complexity, errors, and significant organizational and development efforts for updating and distributing diagnostic software.
Innovation Solution
Diagnostic software is pre-installed on mobile working machines during manufacturing, matching the specific type and version of the control software, allowing for direct download and use on a service computer, eliminating the need for multiple software versions and updates on the technician's device, and enabling remote access for maintenance and updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple versions of diagnostic software are stored on the service computer for different mobile working machine types and control software versions, then comprehensive diagnostic capability is achieved, but device complexity and organizational effort increase significantly
Solution Approach 1:
The patent extracts the version-specific diagnostic software from the service computer and stores it directly in the storage means of the mobile working machine itself. The service computer only needs to download and execute the appropriate software version from the machine's storage, eliminating the need to maintain a library of multiple software versions on the service computer.
Solution Approach 2:
The storage means of the mobile working machine acts as an intermediary, holding the version-specific diagnostic software that matches the control software version. This intermediary storage location allows the service computer to access the correct software version without needing to manage multiple versions itself.
2Adaptability or versatility
If the interface of test and diagnostic software is changed during production to enable innovation and adaptation, then adaptability improves, but reliability of software version matching deteriorates
Solution Approach 1:
The diagnostic software is pre-configured to match the control software version at the time of mobile working machine production. The software version compatibility is established in advance, before the service technician uses it, ensuring that the correct version is always used without requiring manual selection or verification.
Solution Approach 2:
The service computer automatically identifies the control software version of the mobile working machine and uses this information to download the corresponding diagnostic software version from the storage means. This feedback mechanism ensures that the correct software version is always selected without manual intervention.
3Reliability
If updated versions of diagnostic software are distributed to service computers after mobile working machine developments, then software currency is maintained, but productivity and time efficiency decrease
Solution Approach 1:
The service computer automatically downloads the required diagnostic software version directly from the storage means of the mobile working machine during the diagnostic process. This self-service approach eliminates the need for manual software updates and distribution to service computers, as the software is obtained on-demand from the machine itself.
4Measurement precision
If correct software version selection is mandatory to avoid errors, then diagnostic accuracy improves, but ease of operation deteriorates
Solution Approach 1:
The service computer automatically identifies the control software version of the mobile working machine through the interface connection and uses this feedback information to automatically select and download the matching diagnostic software version. This eliminates manual software version selection entirely, making the process as simple as connecting the service computer to the machine.

AI summary
The method involves connecting a service computer (7) e.g. notebook computer with an interface (9) of working machine (2) through a data cable (8). The diagnostic software is stored in memory unit of working machine by service computer. The service computer is controlled by an employee in the factory, through a wireless remote data link (14). An independent claim is included for mobile working vehicle.
