Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a compact structure is adopted to reduce size and weight, then handheld convenience is improved, but air passage layout becomes constrained leading to higher suction power loss
Solution Approach 1:
The device housing is disposed inside the cup casing, with the dust removal chamber formed between the inner surface of the cup casing and the outer peripheral surface of the device housing. This nested arrangement allows the air passages to be compactly organized without increasing overall device volume, thereby reducing size and weight while maintaining effective air flow paths that minimize suction power loss.
Solution Approach 2:
The dust removal chamber surrounds the device housing along the circumferential direction, creating a three-dimensional air passage layout. This spatial arrangement optimizes the air flow path within the constrained compact structure, ensuring efficient dust separation while minimizing energy loss despite the reduced size.
2Volume of moving object
If a compact structure is adopted to reduce size and weight, then handheld convenience is improved, but structural complexity increases to achieve high energy efficiency
Solution Approach 1:
The negative pressure device is integrated within the device housing, combining the motor and air passage functions into a single compact unit. The device housing serves multiple functions: it contains the negative pressure device, forms part of the air passage structure, and provides mounting surfaces for the cyclone separating device. This merging of functions reduces overall device volume while avoiding excessive structural complexity through functional integration.
Solution Approach 2:
The cup casing serves multiple purposes: it contains the dust collection chamber, provides structural support, and forms part of the air passage system. The device housing similarly performs multiple functions including housing the motor, guiding air flow, and providing mounting structures. This multi-functionality allows the cleaner to achieve compact dimensions without requiring additional separate components that would increase structural complexity.
3Use of energy by moving object
If air passage layout is optimized for compactness, then energy efficiency is improved, but dust separation performance may deteriorate
Solution Approach 1:
The dust separation process is divided into multiple stages using sequential cyclone chambers. The first cyclone chamber performs initial dust separation, and the second cyclone chamber provides further separation of finer particles. This segmented approach maintains high dust removal capability despite the compact air passage layout, ensuring that energy efficiency is not compromised by reduced separation performance.
Solution Approach 2:
The air passage structure acts as an intermediary that efficiently transports dust-laden air from the suction inlet through both cyclone chambers to the exhaust outlet. The optimized air passage design ensures smooth airflow transitions and minimizes turbulence losses, maintaining high energy efficiency while the sequential cyclone chambers ensure thorough dust separation performance.
