Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic lifting device controllers are limited by restricted input of control commands and display of simulation, which are confined to the integrated controller, making simulation time-consuming and inefficient.
Innovation Solution
A wireless and/or wired communication system between a mobile control module and the controller allows input of parameters for further positions and lifting loads, with processors calculating and comparing data to assess feasibility, ensuring safe and efficient operation by transmitting data between modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the controller has an integrated display and control interface, then the control functions are complete, but the user is restricted to the location of the controller and simulation is time-consuming
Solution Approach 1:
The control system is segmented into two independent parts: a stationary controller with processing unit and a mobile control module with display and input interface. This allows the user to operate the system from any location within communication range while the controller remains fixed on the lifting device.
Solution Approach 2:
A wireless communication interface acts as an intermediary between the mobile control module and the stationary controller. This mediator enables data transmission and control commands to be exchanged without physical connection, allowing user mobility while maintaining system integration.
2Productivity
If parameters for further positions and lifting loads are input at the mobile control module, then user mobility is improved, but data transmission and processing requirements increase
Solution Approach 1:
The system performs preliminary calculations by pre-computing characteristic information for various positions and lifting loads using the processing unit. These pre-calculated data are stored and can be quickly retrieved and displayed by the mobile control module, avoiding time-consuming real-time calculations during user interaction.
Solution Approach 2:
The system implements feedback by transmitting calculated characteristic information from the controller to the mobile control module. This allows the user to see immediate results of parameter inputs, enabling efficient iteration through different scenarios without waiting for prolonged processing times.
3Reliability
If the processor calculates and compares data for feasibility assessment, then safety is improved, but computational requirements and energy consumption increase
Solution Approach 1:
The processing unit performs preliminary calculations of characteristic information for various operating conditions before actual operation. These pre-computed feasibility assessments are stored and can be quickly referenced during operation, reducing the need for intensive real-time computational operations and lowering energy consumption.

AI summary
An assembly of a controller is to be arranged on a hydraulic lifting device, and a mobile control module can remotely operate the controller. Sensor data can be fed to the controller via signal inputs, and a processor of the controller is configured to calculate first information characteristic of a current position of the hydraulic lifting device from the sensor data and from specific data of the hydraulic lifting device stored in a memory. The controller has an operating mode in which parameters for a further position of the hydraulic lifting device and/or for a lifting load can be input at the mobile control module. Second information characteristic of the further position and/or the lifting load is calculated from the parameters, and the stored data is compared with the first information and/or the specific data.
