Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the handheld cleaner uses a conventional structure with separate components for dust collection and motor housing, then it provides sufficient dust collection capacity, but it results in large volume and great weight making it inconvenient for handheld use
Solution Approach 1:
The device housing and cyclone separating member are integrated into a one-piece structure, merging the dust collection chamber and separation mechanism into a single unified component. This integration eliminates the need for separate housings and reduces the overall volume of the cleaner while maintaining adequate dust collection capacity.
Solution Approach 2:
The first cyclone separating member is disposed within the dust removal chamber defined by the device housing and cup casing, with the negative pressure device nested within the device housing. This nested arrangement allows compact packaging of multiple functional components in a small volume, making the cleaner lightweight and convenient for handheld use.
2Loss of energy
If the handheld cleaner uses a conventional layout of air passages, then it provides sufficient dust collection capacity, but it results in high suction power loss
Solution Approach 1:
The first cyclone separating member surrounds the device housing along the circumferential direction, creating a three-dimensional dust removal chamber that efficiently utilizes spatial arrangement. This circumferential positioning optimizes airflow paths and reduces suction power loss by minimizing turbulence and resistance in the air passage layout.
3Object-generated harmful factors
If the handheld cleaner uses conventional noise levels, then it provides sufficient suction power, but it results in noisy operation disturbing residents
Solution Approach 1:
The negative pressure device is positioned within the device housing at a side of the cyclone separating member, extracting and isolating the noise-generating motor component from the dust collection chamber. This separation reduces noise transmission to the surrounding environment while maintaining sufficient suction power for effective cleaning.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution results in a handheld cleaner that is easy to use, has high energy efficiency, low noise, and achieves a good cleaning effect, addressing the issues of size, weight, and suction power loss in existing handheld cleaners.
Implementation Method 1
a first cyclone separating member disposed in the dust removal chamber and surrounding the device housing along a circumferential direction of the device housing; negative pressure device makes dusty air enter the dust removal chamber for dust and air separation through the first cyclone separating member
Implementation Method 2
a negative pressure device disposed within the device housing, such that negative pressure device makes dusty air enter the dust removal chamber
