Mobile Terminal Wireless Flow Rate Setting for Hydraulic Attachments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow rate setting systems for working machines, such as backhoes and skid steer loaders, are inconvenient for operators who own various attachments, as they require preliminary storage of attachment images to set the maximum flow rate, which is not always feasible.
Innovation Solution
A flow rate setting system utilizing a mobile terminal for wireless communication, which includes components to obtain and output identification information and maximum flow rates, allowing easy setting of the flow rate via a mobile device, even for attachments not previously stored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a display device with preliminarily-stored attachment images is used for setting maximum flow rate, then the flow rate can be set for stored attachments, but the system becomes inconvenient when attachments are not preliminarily stored
Solution Approach 1:
The mobile terminal serves multiple functions: it acts as both an input device for flow rate settings and a universal interface for all attachment types. By using a smartphone or tablet that operators already possess, the system eliminates the need for machine-specific display devices while maintaining compatibility with any attachment through wireless communication and code scanning capabilities.
Solution Approach 2:
The mobile terminal acts as an intermediary between the operator and the working machine's control system. Instead of directly interacting with the machine's display or control panel, the operator uses the mobile terminal to communicate attachment identification information and flow rate settings wirelessly, simplifying the interaction process.
2Ease of operation
If attachment images are preliminarily stored in the working machine for flow rate setting, then setting can be performed for those attachments, but the system complexity increases and convenience decreases for operators with various attachments
Solution Approach 1:
The attachment image storage and processing functionality is extracted from the working machine and transferred to the mobile terminal. The mobile terminal stores and processes attachment identification information (such as codes or images) independently, then communicates only the necessary flow rate settings back to the machine, reducing the burden on the machine's system.
Solution Approach 2:
Instead of storing actual attachment images in the working machine, the system uses code representations (such as QR codes or barcodes) that can be scanned by the mobile terminal. This copying approach simplifies data storage and processing while maintaining accurate attachment identification.
3Productivity
If a dedicated display device is used for flow rate setting, then settings can be made for stored attachments, but the operation becomes inconvenient when attachments are not in the stored list
Solution Approach 1:
The mobile terminal captures and stores attachment identification information (codes or images) in advance before the actual flow rate setting operation. This preliminary action of scanning and storing attachment data eliminates the need for manual input during the setting process, improving both productivity and ease of operation.
Solution Approach 2:
The system enables self-service attachment registration through automatic code scanning and recognition. When an attachment is scanned, the mobile terminal automatically identifies it and retrieves or creates the corresponding flow rate settings without requiring manual intervention or lookup in stored lists.
