Solution Overview
Problem
Existing portable, motor-driven work and rescue appliances face challenges in accurately monitoring their operation and maintaining operational reliability, especially under varying environmental conditions, leading to potential failures in rescue operations due to undetected damage or wear.
Innovation Solution
A method that utilizes the electrical energy source as a transmitter and data collector for operating parameters, enabling precise monitoring and analysis of usage history, allowing for timely servicing and data-driven decision-making, while simplifying equipment complexity by using the charging process for data transmission and potential firmware updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If vibration sensing is used to monitor appliance use, then monitoring capability is provided, but measurement precision is insufficient and device complexity increases
Solution Approach 1:
The patent introduces an intermediary device (monitoring unit with sensor) that attaches to the appliance without requiring modifications to the appliance itself. This sensor detects acoustic emissions during operation and transmits data externally, eliminating the need for complex appliance-specific adaptations while achieving precise usage monitoring.
Solution Approach 2:
The patent replaces mechanical vibration sensing with acoustic emission detection. By listening to the acoustic signals generated during appliance operation rather than mechanically sensing vibrations, the system achieves more precise usage history detection with simpler device integration.
2Reliability
If comprehensive operating data is collected and transmitted centrally, then reliability of rescue operations is improved through better maintenance planning, but loss of time occurs during data management and analysis
Solution Approach 1:
The patent implements preliminary data collection and continuous monitoring, so that usage history and operating parameters are already available and analyzed before failures occur. This allows maintenance to be scheduled proactively based on actual appliance condition rather than reactively after problems arise, reducing operational downtime.
Solution Approach 2:
The patent establishes a feedback loop where operating data is continuously collected, transmitted to a central server, analyzed, and used to generate maintenance recommendations that are communicated back to users. This automated feedback system reduces manual data processing time and enables timely maintenance interventions.
3Manufacturing precision
If individual appliance monitoring is implemented, then manufacturing precision of service measures is improved, but quantity of substance increases due to multiple data collection points
Solution Approach 1:
The patent extracts only the essential operating parameters and usage history data needed for maintenance planning from the total data set generated by the appliance. By selecting and transmitting only relevant data points (acoustic emissions, operational status, usage duration) rather than all possible parameters, the system achieves customized service measures with reduced data transmission volume.
Data Source
AI summary
A method is for operating an electromechanical or electrohydraulic work appliance or rescue appliance that can be carried and used by an operator, having a movable tool insert, a spreading tool or a lifting tool, a housing, an electric motor, a pump or a mechanical transmission driven by the electric motor, for actuating the tool insert. The appliance has an exchangeable, rechargeable appliance electrical energy source, having a housing in or on the rescue appliance. During operation of the appliance, operating data of the appliance and/or of the energy source are acquired and transferred into a data carrier or data storage device in the electrical energy source. The electrical energy source is removed from the appliance and connected to a charging device. The operating data stored in the data carrier or storage device of the electrical energy source are read by the charging device and transferred to a network.
