Vacuum Filter Dust Remover With Elastic Buffer Striking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners require manual effort to remove fine dust from cylindrical filters, which degrades filter performance and can cause damage when automated striking mechanisms are used.
Innovation Solution
A dust remover system with a rigid rotary member, rotating buffer members, a striking member, and elastic members is integrated into the vacuum cleaner, where the striking member rotates to remove dust from the filter while the elastic members absorb shock, preventing filter damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a motor-driven striking rod is installed inside the cylindrical filter to automatically remove dust, then operational convenience is improved, but the filter durability deteriorates due to repeated striking damage
Solution Approach 1:
A rubber buffer member is introduced as an intermediary between the motor-driven striking rod and the filter surface. This buffer member rotates with the striking rod but contacts the filter through its peripheral surface, absorbing and distributing the impact forces. The buffer member acts as a mediator that enables automatic dust removal while protecting the filter from direct damage by the rigid striking rod.
Solution Approach 2:
The striking mechanism changes from direct rigid contact to indirect contact through a deformable rubber buffer. The material property parameter changes from rigid (striking rod) to elastic (rubber buffer), allowing the system to maintain the dust-removal function while reducing the harmful impact parameters on the filter structure.
2Reliability
If manual striking is used to remove dust from the filter, then filter durability is maintained, but operational convenience deteriorates due to required manual effort
Solution Approach 1:
The system transitions from manual service to self-service automation. The motor-driven rotating buffer mechanism automatically performs the dust removal function without requiring operator intervention. The buffer member rotates and strikes the filter surface autonomously, enabling the system to serve itself in maintaining filter performance.
Solution Approach 2:
The manual mechanical striking action is replaced with an automated motor-driven mechanical system. The electric motor provides the rotational motion that drives the buffer member, substituting human physical effort with an automated electromechanical system that performs the same dust removal function.
3Productivity
If a rigid striking rod is used to strike the filter, then dust removal effectiveness is improved, but the shock applied to the filter increases causing damage
Solution Approach 1:
The rubber buffer member provides beforehand cushioning between the striking rod and the filter. By positioning the elastic buffer in advance between the rigid striker and the filter surface, the system prepares a protective layer that will absorb and distribute impact forces before they reach the filter, preventing shock damage while maintaining dust removal capability.
Solution Approach 2:
The rigid striking rod is replaced with a flexible rubber buffer member that contacts the filter. This flexible element can deform during impact, absorbing shock energy through elastic deformation rather than transmitting rigid impact forces to the filter structure, thereby reducing harmful shock effects while maintaining contact for dust removal.
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 system effectively removes dust from the filter without damaging it, improving filter durability and maintaining suction performance by distributing the shock load through elastic absorption.
Implementation Method 1
an elastic member having an end portion coupled to the rotating buffer member and another end portion coupled to the rigid rotary member so as to apply an elastic recovery force to the rotating buffer member to rotate in a direction in which the rigid rotary member rotates
Implementation Method 2
a striking member of a plate type having an end portion fixed to the rotating buffer member and another end portion contacting the filter to strike the filter

AI summary
A dust remover for a vacuum cleaner is provided inside a filter and is rotated by a motor. The dust remover includes: a rigid rotary member perpendicularly coupled to an output shaft of the motor to be rotated according to a rotation of the output shaft; a rotating buffer member assembled with an end portion of the rigid rotary member to be rotatable around a rotary shaft that is in parallel with the output shaft; a striking member having an end portion fixed to the rotating buffer member and another end portion contacting the filter; and an elastic member having an end portion coupled to the rotating buffer member and another end portion coupled to the rigid rotary member so as to apply an elastic recovery force to the rotating buffer member to rotate in a direction in which the rigid rotary member rotates.
