Autarkic Data Unit for Civil Engineering Tool Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing civil engineering tools face challenges in efficient data transmission and servicing due to compatibility issues with different manufacturers' machines, leading to inadequate servicing and data recording, especially on larger construction sites.
Innovation Solution
An autarkic operating data unit with sensors and data storage is integrated into the civil engineering tool, allowing independent data acquisition and storage, which can be retrieved directly from the tool, enabling reliable servicing and data security, even when used across various machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission is connected via drill pipe to control device on carrier, then data can be transmitted to control room, but data transmission is adversely affected or impossible when tools are exchanged between different manufacturers' machines
Solution Approach 1:
The data storage function is segmented from the machine control system and placed directly in the tool. The tool now has its own independent data storage device, separating the data acquisition and storage functions from the machine's control system, enabling the tool to retain data independently regardless of which machine it is attached to.
Solution Approach 2:
The tool acts as an intermediary data storage node between the sensor and the control room. Instead of requiring direct connection through the machine's control system, the tool stores data locally and can transmit it directly to the control room or have data retrieved manually, serving as a standalone intermediary that works with any machine.
2Loss of information
If control device is mounted on carrier outside ground in operator's cabin, then data can be monitored in real time, but servicing information is lost when tools are frequently exchanged between machines
Solution Approach 1:
The tool performs preliminary data storage action during operation, accumulating operating data in its own storage device while attached to any machine. This preliminary data capture ensures that servicing information is preserved before tool exchange occurs, eliminating the need to rely on the machine's control system to retain data.
Solution Approach 2:
The tool serves itself by independently acquiring, storing, and managing its own operating data. The self-service capability includes automatic data recording during operation and the ability to transmit or have data retrieved for servicing purposes, without requiring the machine's control system to maintain the data.
3Reliability
If data is transmitted through machine's control device, then central control room can record and evaluate data, but data security and quality are compromised when tools are used on machines without data transmission capability
Solution Approach 1:
The data storage function is extracted from the machine's control system and placed directly in the tool. This extraction creates a standalone data repository in the tool that is independent of the machine's control device, ensuring data security and quality regardless of which machine the tool is attached to or whether the machine has data transmission capability.
