Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual rotation of the dust collector is required for reciprocating operation, then dust collection function is achieved, but ease of operation deteriorates due to manual intervention requirement
Solution Approach 1:
The dust collector is designed to automatically pivot and return to its initial position using frictional resistance from the surface being cleaned and the weight distribution of the main body. The system serves itself by utilizing the cleaning action and gravity to drive the pivot motion without manual intervention, resolving the contradiction between ease of operation and automation.
Solution Approach 2:
The dust collector transitions from a static structure requiring manual rotation to a dynamic system that automatically pivots during operation. The frictional contact between the dust collecting brush and the surface being cleaned creates a dynamic pivot mechanism that adapts to the cleaning motion, eliminating the need for manual rotation.
2Productivity
If the dust collector has a semi-conical shape, then dust collection capability is improved, but stability deteriorates due to changing suction port area and uneven frictional resistance
Solution Approach 1:
The dust collector uses an asymmetric pivot mechanism where the main body is positioned offset from the center of the dust collecting brush. This asymmetric weight distribution creates a pivot point that allows the dust collector to rotate smoothly while maintaining stable contact with the surface being cleaned, preventing the instability caused by symmetric semi-conical designs.
Solution Approach 2:
The invention changes the geometric parameters of the dust collector from a semi-conical shape with varying cross-section to a design with a cylindrical main body and a flat bottom surface. This parameter change ensures that the suction port area remains constant during rotation and that frictional resistance is evenly distributed, resolving the stability issue while maintaining dust collection effectiveness.
3Area of stationary object
If two dust collectors are arranged in parallel individually, then dust collection coverage is improved, but device complexity increases due to separate operation requirements
Solution Approach 1:
Two dust collectors are merged into a single integrated unit that pivots as one assembly. The main body contains both dust collecting brushes arranged in parallel, and the entire structure rotates together around a common pivot point. This merging reduces device complexity by eliminating the need for separate pivot mechanisms while maintaining the expanded dust collection coverage.
Solution Approach 2:
The single main body serves multiple functions by housing both dust collectors and providing a unified pivot mechanism. The frictional resistance from the surface being cleaned acts on the entire assembly, making the pivot system universal for both dust collectors simultaneously, thereby reducing overall system complexity while maintaining wide coverage.
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
Enables automatic and stable dust collection without manual rotation, maintaining consistent suction pressure and reducing the number of brushes needed, ensuring efficient dust collection and storage.
Implementation Method 1
The pivot of the dust collector operates by the frictional resistance generated between the surface to be cleaned and the dust collecting first dust collecting brush arranged on the outer peripheral surface of the dust collector
Implementation Method 2
the dust stored inside the cleaning body moves to the dust collecting part of the main body of the electric vacuum cleaner by the suction force of the electric vacuum cleaner

AI summary
A dust collecting device and an electric vacuum cleaner with it are provided. The dust collecting device comprises a main body with an opening, a first dust collector with a first dust collecting brush for collecting dust, and a second dust collector with a second dust collecting brush for collecting dust; the first dust collector and the second dust collector are rotatably held in parallel inside the main body; when the first dust collecting brush is at the opening, the first dust collecting brush is inclined toward the second dust collector; when the second dust collecting brush is at the opening, the second dust collecting brush is inclined toward the first dust collector. The dust collecting device can collect dust even when the power of the electric vacuum cleaner is turned off and can be used at any time without worrying about noise.
