Remote control for controlling an operation status of a suction device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction devices, such as vacuum cleaners, lack a remote control option for manual control when used with hand-held power tools, making it cumbersome to synchronize their operation with the power tool's usage.
Innovation Solution
A remote control system that includes a radio receiver to receive signals from a communication device attached to the suction hose, processing these signals to determine the power tool's status and transmitting corresponding control signals to the suction device, allowing manual control of the suction device's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a suction device is automatically activated based on radio signal from a communication device, then the suction device can be synchronized with power tool operation, but the user cannot manually control the suction device operation
Solution Approach 1:
The remote control acts as an intermediary device between the communication device and the suction device. It receives radio signals from the communication device, processes them to determine power tool status, and transmits appropriate control signals to the suction device. This intermediary role enables both automatic operation (through signal relay) and manual control (through direct remote control buttons), resolving the contradiction between automation and user control.
2Device complexity
If the suction device is controlled directly by the communication device, then the system is simpler, but the user experience is reduced
Solution Approach 1:
The remote control serves as a user-friendly intermediary that enhances the user experience by providing manual control buttons and a more intuitive interface. While it adds a component to the system, it significantly improves ease of operation by allowing users to directly control suction device functions without complex configurations or relying solely on automatic detection.
3Ease of operation
If the remote control receives signals from the communication device, then manual override is enabled, but the device complexity increases
Solution Approach 1:
The remote control is designed with multi-functionality to justify its added complexity. It can both receive and process radio signals from the communication device for automatic control, and also function as a standalone manual control device with its own buttons and interface. This universal capability enables manual override while maintaining automatic operation modes, making the additional complexity worthwhile.

AI summary
The invention refers to a remote control (50) for controlling an operation status of a suction device (2). The remote control (50) comprises a radio transmitter (88) for transmitting a first radio signal (30) to the suction device (2) for turning on or off the suction device (2). It is suggested that the remote control (50) further comprises a radio receiver (90) for receiving a second radio signal (54) from a communication device (32) located at a second end (16) of a suction hose (12), which is connected to a suction opening (10) of the suction device (2) with its first end (14) and to an air outlet (18) of a hand-held electric or pneumatic power tool (20) with its opposite second end (16). The communication device (32) detects a current operation status of the hand-held electric or pneumatic power tool (20) and emits the second radio signal (54) indicative of the current operation status of the hand-held electric or pneumatic power tool (20). The remote control (50) derives from the received second radio signal (54) the current operation status of the hand-held electric or pneumatic power tool (20) and transmits a respective first radio signal (30) in order to automatically turn on or off the suction device (2) depending on the derived current operation status of the hand-held electric or pneumatic power tool (20).
