Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the external communication device is integrated into the vacuum cleaner housing, then the control connection can be established, but communication interference and unauthorized activation occur
Solution Approach 1:
The communication module is separated from the vacuum cleaner housing and integrated into the energy storage module or machine tool. This segmentation isolates the communication function from potential interference sources while maintaining wireless control capability, thereby improving reliability without exposing the vacuum cleaner to communication interference and unauthorized activation.
Solution Approach 2:
The energy storage module or machine tool acts as an intermediary device that maintains the control connection between the vacuum cleaner and the operating system. This intermediary role allows the vacuum cleaner to be controlled reliably while the communication module remains protected within the intermediary device, preventing direct exposure to harmful communication environments.
2Reliability
If the communication module is arranged remotely from the vacuum cleaner housing, then communication security is improved, but the device complexity increases
Solution Approach 1:
The communication module is merged with the energy storage module or machine tool, which are already essential components of the system. This merging approach places the communication function in a remote location for security reasons while avoiding the need for separate communication hardware, thereby maintaining communication security without significantly increasing device complexity.
Solution Approach 2:
The energy storage module or machine tool serves multiple functions: power supply, control, and communication. By making this component universal, the patent achieves remote communication security while avoiding the addition of dedicated communication hardware that would increase device complexity.
3Ease of operation
If the external communication device is always ready to establish control connection, then responsiveness is improved, but unauthorized activation risk increases
Solution Approach 1:
The communication module is pre-configured and ready within the energy storage module or machine tool, but the actual control connection establishment is triggered only by authorized activation signals. This preliminary preparation ensures rapid response when needed while preventing unauthorized activation, as the communication function remains dormant until properly authorized.
Solution Approach 2:
The system implements feedback mechanisms where the vacuum cleaner and control system verify authorization before establishing control connections. The communication module receives and validates activation signals, ensuring that only authorized operations can initiate control connections, thereby balancing responsiveness with security.
