Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filtration systems in mobile surface maintenance machines fail to effectively and efficiently remove debris from filter surfaces, leading to reduced performance and increased dust emission.
Innovation Solution
A vacuum-based filtration system incorporating a filter shaker assembly with a cylindrical pleated media filter and a debris hopper, where the filter shaker mechanism uses eccentric masses driven by an electric motor to periodically dislodge and collect debris, which is then deposited into a hopper, utilizing a balanced radial motion to minimize noise and enhance durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional filtration systems are used in mobile surface maintenance machines, then the structure is simple, but debris cannot be effectively removed from filter surfaces leading to reduced performance
Solution Approach 1:
The filter shaker assembly utilizes an electric motor to generate mechanical vibrations that are transmitted to the filter surface through a shaker plate. These vibrations dislodge accumulated debris from the filter media, enabling effective cleaning without requiring complex manual intervention or disassembly procedures.
Solution Approach 2:
The filtration system incorporates periodic shaking cycles where the filter shaker assembly is activated at intervals to remove debris. This periodic action maintains filter performance over time by preventing debris buildup, balancing cleaning effectiveness with operational continuity and system simplicity.
2Productivity
If filter shaking mechanism is added to remove debris, then debris removal effectiveness improves, but noise level increases
Solution Approach 1:
The filter shaker assembly incorporates counterweights that are strategically positioned to balance the rotating components. This counterbalancing reduces vibrations and noise generated during the shaking operation, allowing effective debris removal while maintaining acceptable noise levels for mobile surface maintenance operations.
3Object-generated harmful factors
If frequent filter cleaning is performed to maintain performance, then dust emission is reduced, but filter durability decreases due to mechanical stress
Solution Approach 1:
The gentle mechanical vibrations from the shaker plate effectively dislodge debris without applying excessive force to the filter media. This vibration-based cleaning method reduces mechanical stress compared to more aggressive cleaning approaches, thereby extending filter life while maintaining low dust emission levels through regular cleaning cycles.

AI summary
A filter shaking assembly for a floor surface maintenance machine including a filter assembly in fluid communication with the debris hopper and having a cylindrical filter held against a shaker plate. The shaker plate is vibrated by a shaker motor at least partially positioned within an interior of the filter and eccentric mass to remove an accumulation of debris from the surface of the filter. The eccentric mass may include two eccentric masses positioned on a common shaft of the shaker motor.
