System formed of suction device and hand-held power tool, and method for operating the system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems with suction devices and hand-held power tools lack effective safety measures to ensure that dust and dirt particles generated during tool operation are immediately extracted, leading to potential safety hazards.
Innovation Solution
A method is introduced where a communication link between the suction device and hand-held power tool is established, requiring a start signal from the suction device to activate the power tool, ensuring that dust and dirt particles are directly and immediately extracted by the suction device, enhancing work safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hand-held power tool is activated without verifying suction device operation, then the power tool can be used independently, but dust and dirt particles are not immediately extracted leading to safety hazards
Solution Approach 1:
The suction device sends a start signal to the hand-held power tool before the power tool can be activated. This preliminary action ensures that the suction device is operational and ready to extract dust and dirt particles before the power tool generates harmful particles, thereby improving work safety without significantly increasing operational complexity.
Solution Approach 2:
A communication link acts as an intermediary between the suction device and the hand-held power tool. This intermediary transmits the start signal from the suction device to the power tool, enabling coordinated operation and ensuring that the power tool only operates when the suction device is ready, thus improving safety while maintaining simple operation through automated communication.
2Reliability
If a communication link with start signal requirement is implemented, then work safety is enhanced by ensuring immediate dust extraction, but the system operation becomes more complex
Solution Approach 1:
The suction device automatically sends the start signal to the hand-held power tool through the communication link without requiring manual intervention from the user. This self-service mechanism ensures that the safety protocol is consistently applied while keeping the operation simple, as the user only needs to activate their respective devices normally and the coordination happens automatically.

AI summary
The disclosure relates to a method for operating a system that includes at least one suction device and at least one hand-held power tool. The method includes establishing a communications link between the suction device and the hand-held power tool by means of at least one suction device communication unit and at least one hand-held power tool communication unit, and transmitting at least one communication signal by means of the communications link from the hand-held power tool, in particular the hand-held power tool communication unit, to the suction device, in particular the suction device communication unit. When the suction device is switched on, at least one start signal is sent to the hand-held power tool, the hand-held power tool being activatable only if the start signal is received by the hand-held power tool.
