Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used for control connection between vacuum cleaner and machine tool, then ease of operation is improved, but reliability deteriorates due to communication interruptions and unauthorized activation
Solution Approach 1:
The patent introduces a communication module as an intermediary component that establishes a dedicated wireless communication channel between the vacuum cleaner and machine tool. This module acts as a mediator that filters and validates communication signals, preventing unauthorized activation while maintaining reliable control. The communication module processes and verifies authentication signals before executing control commands, thus resolving the contradiction between wireless convenience and connection stability.
2Device complexity
If communication module is integrated into vacuum housing, then device complexity is reduced, but reliability deteriorates due to interference and limited communication range
Solution Approach 1:
The patent segments the communication function by separating the communication module from the main vacuum housing. The communication module can be arranged remotely or on separate components such as the suction hose or machine tool interface. This segmentation allows the communication function to be optimized independently, improving signal quality and reliability while reducing electromagnetic interference from the vacuum motor and other components.
3Reliability
If remote communication module is added to improve communication reliability, then control connection stability is improved, but device complexity increases
Solution Approach 1:
The communication module is designed with multi-functionality to reduce overall system complexity. It integrates multiple functions including wireless communication, authentication verification, and control signal processing into a single module. The module can operate in different modes and interface with various components (vacuum housing, suction hose, or machine tool), making it a universal solution that improves reliability without proportionally increasing complexity.
