Mobile Hydraulic Units in a Mesh Network for Wireless Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile hydraulic systems lack an efficient interface for retrieving diagnostic and status data, requiring manual disconnection and reconnection of sub-units for data retrieval, which is time-consuming and costly.
Innovation Solution
Implementing a wireless communication network among hydraulic units with mesh network topology, allowing direct data exchange between units without central components, enabling continuous data acquisition and reducing manual effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a limited application interface is used for system operation, then system operation is sufficient and simple, but data retrieval for diagnostic purposes is inhibited and requires manual disconnection
Solution Approach 1:
The system separates the limited application interface used for operation from the wireless communication interface used for data retrieval. Each hydraulic unit has its own electronic unit with a wireless communication device, allowing independent data access without affecting system operation through the limited interface.
Solution Approach 2:
A wireless communication device acts as an intermediary between the hydraulic units and external diagnostic systems. This intermediary enables data retrieval without requiring manual disconnection or expanding the limited application interface, resolving the contradiction between operational simplicity and diagnostic accessibility.
2Loss of information
If manual disconnection and reconnection of sub-units is performed for data retrieval, then data can be accessed, but time is lost and costs increase
Solution Approach 1:
The patent replaces the mechanical process of manual disconnection and reconnection with a wireless communication system. The wireless communication devices transmit data over a wireless network, eliminating the need for physical intervention and significantly reducing data retrieval time while maintaining full data accessibility.
3Loss of information
If electronic units are directly connected to hydraulic units, then data acquisition is possible, but system complexity increases and manual intervention is required
Solution Approach 1:
The wireless communication devices are integrated into existing electronic units, allowing these units to perform both their original functions and data transmission functions. This multi-functionality enables data acquisition without adding separate dedicated data collection hardware, thereby limiting the increase in system complexity.
4Ease of operation
If a common wireless network is implemented among hydraulic units, then data retrieval is simplified and continuous monitoring is enabled, but device complexity increases
Solution Approach 1:
The patent merges the communication capabilities of multiple hydraulic units into a common wireless network. By combining individual wireless communication devices into a networked system, the patent enables centralized data retrieval and continuous monitoring while distributing the communication functionality across existing units, thereby managing complexity through integration rather than addition.
