Electrical device for actuating a vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for machine tools and energy storage modules fail to securely and efficiently control vacuum cleaners, leading to potential health hazards and environmental damage due to uncontrolled dust release when switching on or off, as multiple devices can inadvertently activate or deactivate the vacuum cleaner.
Innovation Solution
Implementing a wireless communication interface that sends a registration message to establish a control connection with the vacuum cleaner based on the switching status of the machine tool's switching element, ensuring only authorized devices can initiate control commands, and using encrypted communication to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electric devices can send control commands to the vacuum cleaner, then the system is more versatile and adaptable, but unauthorized devices can inadvertently switch off the vacuum cleaner causing dust to enter the environment
Solution Approach 1:
The patent introduces a registration message mechanism as an intermediary step between the control command and the vacuum cleaner's switching action. Before a device can control the vacuum cleaner, it must first send a registration message to the external communication apparatus and receive confirmation. This intermediary registration process ensures that only authorized devices can subsequently send control commands, preventing unauthorized switching off while maintaining versatility.
2Speed
If wireless communication is implemented without registration messages, then the control connection can be established quickly, but unauthorized devices can access and control the vacuum cleaner
Solution Approach 1:
The patent implements a preliminary registration action that must be completed before the control connection becomes active. The device sends a registration message in advance, and only after receiving confirmation from the external communication apparatus does the control connection become valid. This preliminary action ensures security is established before any control commands can be executed, maintaining both speed and reliability.
3Reliability
If a registration message system is implemented, then unauthorized access is prevented, but the communication protocol becomes more complex
Solution Approach 1:
The patent segments the communication process into distinct phases: a registration phase where the device sends a registration message and receives confirmation, and a control phase where authorized control commands are exchanged. This segmentation simplifies the overall protocol design by clearly separating the authentication function from the control function, making the system more manageable despite the added security requirements.
