Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If only the vacuum module is used for cleaning heavy granular powder particles, then the suction force must be increased, but this results in increased power consumption and noise
Solution Approach 1:
The patent combines the brush module and vacuum module into an integrated cleaning system where the brush module performs primary collection and guidance of granular powder particles, while the vacuum module provides supplementary suction. This merging allows the system to achieve effective cleaning of heavy particles without requiring excessive suction force from the vacuum alone, thereby reducing power consumption and noise.
Solution Approach 2:
The cleaning function is segmented into two distinct modules: the brush module responsible for mechanical collection and guidance of particles to the suction hole, and the vacuum module responsible for actual suction removal. This segmentation allows each module to operate at optimal efficiency levels, with the brush handling the heavy lifting of particle collection and the vacuum focusing only on removal, avoiding the need for high power consumption.
2Device complexity
If the suction channel is disposed away from the dust collecting space, then the structure is simpler, but the dust collecting ability deteriorates due to reduced suction power effectiveness
Solution Approach 1:
The suction channel is nested within or adjacent to the dust collecting space, with the dust collecting space positioned to communicate directly with the suction channel. This nested arrangement allows the suction force to be applied most effectively at the dust collection point without requiring complex external channel structures, maintaining both structural simplicity and high dust collecting ability.
3Power
If the fan blower operates at high rotation speed for better cleaning performance, then the suction power increases, but the power consumption and noise increase
Solution Approach 1:
The system dynamically adjusts the fan blower rotation speed based on real-time detection of dust concentration and cleaning requirements. The intelligent detection functions monitor cleaning conditions and automatically control the fan blower speed, allowing the system to operate at high power only when necessary for heavy particle removal, and at lower speeds during normal operation, thereby reducing overall noise levels while maintaining effective suction power when needed.
