Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic systems face complexity in parameterizing control electronics for hydraulic components, requiring laborious manual adjustments and ensuring optimal operation, especially after component replacements, due to production tolerances and the need for specific parameter transfer.
Innovation Solution
A hydraulic system with an external database and identification elements allows for easy parameterization by connecting a configuration device, such as a smartphone, to access and transfer specific parameters to the control electronics, reducing manual effort and ensuring optimal operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual iterative test method is used to adjust parameters, then specific adaptation to hydraulic components is achieved, but the process becomes extremely complicated and laborious
Solution Approach 1:
The patent uses identification elements (copies of component identities) stored in a database to automatically retrieve and transfer parameters, replacing manual iterative testing. The configuration means reads the identification element and automatically obtains the corresponding parameters without manual adjustment.
Solution Approach 2:
The system enables self-service parameterization where the hydraulic component itself (via its identification element) provides the necessary information for parameter retrieval. The component essentially configures itself by presenting its identification, and the system automatically retrieves and applies the correct parameters.
2Ease of operation
If parameters are determined in advance by iterative test method, then parameterization is simplified, but optimal operation cannot be ensured due to production tolerances
Solution Approach 1:
The patent applies local quality by storing specific, component-individual parameters in the database rather than using generic pre-configured values. Each hydraulic component has its own unique parameters stored and retrieved based on its identification element, ensuring optimal operation for each specific component while maintaining simple automated transfer.
3Duration of action of stationary object
If hydraulic components are replaced due to wear, then system continuity is maintained, but re-parameterization becomes necessary and complex
Solution Approach 1:
The patent prepares for component replacement in advance by storing all necessary parameters in the database associated with each component's identification element. When a component is replaced, the new component's identification element is read and parameters are automatically transferred, eliminating the need for complex re-parameterization procedures.
4Reliability
If program code adaptation is required after hydraulic component replacement, then operation quality is maintained, but programming skills are required that are not always available
Solution Approach 1:
The patent copies the identification information from the hydraulic component to the control electronics through the configuration means. This automatic copying process ensures that the correct parameters are transferred without requiring manual program code adaptation or specialized programming skills on site.

AI summary
A hydraulic system having a hydraulic device and at least one external database is provided. The hydraulic device comprises at least one hydraulic component, a control electronics having a memory to control the hydraulic component, and an identification element assigned to the hydraulic component. Specific parameters for the hydraulic component are stored in the external database, and the hydraulic component can be clearly identified by a configuration means via the identification element. The configuration means can be connected to the control electronics and the external database to access the specific parameters so that these can be transferred to the memory of the control electronics by means of the configuration means. Further, the disclosure relates to a method for parameterizing control electronics of a hydraulic device of a hydraulic system as well as an arithmetic unit for compiling a program code for the operation of a hydraulic assembly with several components.
