Wireless Remote Control for Cutting Tools in Hazardous Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools lack the capability for remote operation, which poses safety risks and operational challenges when dealing with hazardous environments or hard-to-reach locations.
Innovation Solution
A cutting tool system that includes a body with two blades, an actuator to move the blades, and a controller that enables wireless communication with a remote device. The system allows for remote control of the cutting tool through a series of signals and user interface interactions, enabling safe operation from a distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cutting tool is operated manually by the operator, then the operation is simple and direct, but the operator is exposed to safety risks in hazardous environments
Solution Approach 1:
A remote device serves as an intermediary between the operator and the cutting tool. The operator interacts with the remote device through a user interface, which transmits commands wirelessly to the cutting tool controller. This mediator allows the operator to control the cutting tool from a safe distance while maintaining operational capability.
Solution Approach 2:
The patent replaces direct mechanical control (manual operation) with wireless electronic communication. The cutting tool controller receives wireless signals from the remote device and automatically actuates the actuator system, eliminating the need for the operator to be physically present at the cutting tool.
2Reliability
If the cutting tool is equipped with remote control capability, then operator safety is improved, but the device complexity increases
Solution Approach 1:
The system is divided into separate functional modules: a cutting tool with actuator and controller, a remote device with user interface, and wireless communication components. This segmentation allows each module to be optimized independently and simplifies the overall system architecture by distributing functions across multiple components.
Solution Approach 2:
The cutting tool controller serves multiple functions: it manages the actuator system for blade control, processes wireless communications from the remote device, and implements safety protocols. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity.
3Reliability
If the cutting tool requires multiple confirmation steps for remote operation, then safety is enhanced, but the operation time increases
Solution Approach 1:
The system requires preliminary actions (trigger lock, mode selection) to be performed before remote operation is enabled. These preliminary steps prepare the cutting tool for remote control and ensure intentional activation, but they are completed once per operation sequence rather than repeatedly during cutting.
Solution Approach 2:
The cutting tool controller provides feedback signals to the remote device confirming the current operational state (e.g., whether the trigger is locked, whether remote mode is active). This feedback mechanism allows the operator to monitor the system state and understand what actions have already been completed, reducing unnecessary delays.

AI summary
An example system includes a cutting tool and a device configured to remotely control the cutting tool. The device is configured to establish a wireless communication with the cutting tool, and the cutting tool is configured to send a first signal to the device indicating that the cutting tool is enabled to be operated remotely responsive to the cutting tool receiving information indicating that a trigger is locked in an “on” state and a remote switch is in a first position. The device is configured to send a second signal to the cutting tool indicating a request to cause the cutting tool to perform a cutting operation responsive to receiving information indicative of actuation of at least one button of a user interface of the device.
