Remote Control Cutting Tool for Hazardous Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools lack remote control capabilities, making it difficult to safely cut cables in hazardous environments such as high-voltage electrical systems or underwater settings, where direct human intervention poses risks.
Innovation Solution
A cutting tool system with wireless communication between a device and the cutting tool, allowing for remote operation by enabling a remote-cut mode, where the cutting tool can be controlled via a user interface to move blades relative to each other, even when the operator is not physically present, ensuring safety by isolating the operator from hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cutting tool is operated manually in hazardous environments, then the operator can directly control the cutting operation, but the operator is exposed to electrical hazards and other dangers
Solution Approach 1:
A remote control device serves as an intermediary between the operator and the cutting tool. The operator controls the cutting tool from a safe distance through wireless communication, eliminating direct exposure to hazardous environments while maintaining operational control. The remote device transmits control signals to the cutting tool's actuator system.
Solution Approach 2:
The patent replaces manual mechanical operation with an electromechanical system. The cutting tool uses an actuator (hydraulic or electric) controlled by a motor, which is in turn controlled by a microprocessor-based controller receiving signals from the remote device. This substitution allows remote operation while maintaining precise control.
2Reliability
If the cutting tool is equipped with remote control capabilities, then operator safety is improved, but the device complexity increases
Solution Approach 1:
The cutting tool is designed with multi-functionality, capable of operating in both manual and remote modes. The control system can switch between different operating modes (manual trigger operation and remote wireless control), making the device adaptable to various operational requirements without requiring separate systems for each mode.
Solution Approach 2:
A microprocessor-based controller acts as an intermediary between the actuator and the remote control device. This controller manages the complexity by processing wireless signals, coordinating actuator operation, and maintaining system state, thereby organizing the complex interactions into a manageable control architecture.
3Force
If the cutting tool uses hydraulic actuation, then powerful cutting force is achieved, but the system requires fluid management infrastructure
Solution Approach 1:
The patent offers an electric motor-driven actuator as an alternative to hydraulic actuation. This substitution eliminates the need for hydraulic fluid, pumps, and associated infrastructure, while still providing sufficient cutting force through direct electric-to-mechanical energy conversion. The electric actuator is controlled by the microprocessor-based controller.
4Adaptability or versatility
If the cutting tool is designed for underwater operation, then access to underwater cables is enabled, but the device requires specialized sealing and protection
Solution Approach 1:
The cutting tool incorporates sealed housings and protective barriers that prevent water ingress while allowing the tool to function underwater. These protective enclosures maintain the internal operating environment separate from the external aquatic environment, enabling underwater operation without requiring the entire system to be fundamentally redesigned for water exposure.
Data Source
AI summary
An example system includes a cutting tool and a device configured to remotely control the cutting tool. In response to receiving information indicative of actuation of a first user interface item, the device sends a first signal to the cutting tool so as to request enabling the cutting tool to be operated remotely. The cutting tool sends a second signal to the device indicating that remote operation of the cutting tool has been enabled. The cutting tool receives information indicating that the trigger has been activated, and sends a third signal to the device indicating that the cutting tool is ready to perform a cutting operation. The device receives information indicative of actuation of a second user interface item, and responsively, sends a fourth signal to the cutting tool so as to cause the cutting tool to perform the cutting operation.
