Anti-static vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-static vacuum cleaners fail to effectively eliminate static electricity, particularly when a large amount of dust is sucked in, leading to persistent static phenomena due to inadequate contact between metal rings and the human body.
Innovation Solution
The anti-static vacuum cleaner electrically connects the static electricity generating portions with the handle through a power supply line, eliminating any load between access points to facilitate efficient electrostatic conduction, using conductive materials like electrically conductive TPU or metal rings for enhanced contact with the human body, thereby guiding static electricity into the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an independent wire is arranged between the metal pipe and handle to conduct static electricity, then static electricity elimination is achieved, but device complexity increases and production cost rises
Solution Approach 1:
The patent merges the static electricity conduction function with the existing power supply line structure. The power supply line, which already connects the battery pack to various components, is utilized to conduct static electricity from the metal pipe to the handle, eliminating the need for a separate independent wire. This integration resolves the contradiction by maintaining static electricity elimination functionality while reducing device complexity and production cost.
2Object-affected harmful factors
If a metal ring with small contact area is used to guide static electricity, then electrostatic conduction is achieved, but contact reliability with human body is insufficient
Solution Approach 1:
The patent employs the user's own body as the conduction path. By designing the handle with conductive material that contacts the user's hand, the system utilizes the user's body to guide static electricity to the ground. This self-service approach resolves the contradiction by ensuring reliable contact (since the user must hold the handle to operate the vacuum cleaner) while effectively eliminating static electricity accumulation.
3Object-affected harmful factors
If additional anti-static components are added to the vacuum cleaner, then static electricity elimination is improved, but manufacturing cost increases
Solution Approach 1:
The patent makes the power supply line serve multiple functions: it supplies power to the vacuum cleaner components and simultaneously conducts static electricity from the metal pipe to the handle. This multi-functionality resolves the contradiction by eliminating the need for additional anti-static components, thereby reducing manufacturing cost while maintaining effective static electricity elimination.
4Use of energy by moving object
If the power supply line includes loads between access points, then normal power supply function is maintained, but electrostatic conduction efficiency is reduced
Solution Approach 1:
The patent segments the power supply line into different functional sections. A specific section of the power supply line is designated for static electricity conduction, with access points directly connected to the metal pipe and handle without intervening loads. This segmentation resolves the contradiction by ensuring efficient electrostatic conduction in the designated path while maintaining the overall power supply function through other portions of the line that may contain loads.
