Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool vacuum cleaners face challenges in efficiently filtering both fine and bulky debris due to limitations in filtration surface area, clogging issues, and incompatibility with standard cartridges, which affect cleaning duration and maintenance complexity.
Innovation Solution
A filtration system comprising a flexible, waterproof pocket that houses a cartridge filtration system, allowing for axial or perpendicular fixation of cartridges, and utilizing tubular sleeves for secure and waterproof attachment, enabling effective collection of both fine and bulky debris and simplifying maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional low-porosity bag is used for filtration, then fine particles are filtered effectively, but the filter surface area is small and clogs quickly
Solution Approach 1:
The filter cartridge is nested inside the flexible bag, creating a dual-layer filtration system. The flexible bag provides the outer filtration layer while the filter cartridge provides an inner pleated filtration layer, maximizing filter surface area within a compact volume.
Solution Approach 2:
The filter cartridge uses longitudinal pleats to transform a two-dimensional flat filter surface into a three-dimensional expanded surface, dramatically increasing the filter surface area while maintaining a compact cylindrical footprint.
2Area of stationary object
If the filter surface area is increased using pleated fabric filter cartridges, then clogging is delayed and filtration fineness is increased, but the cartridge container must be rigid and has fixed dimensions
Solution Approach 1:
The filter cartridge is placed inside a flexible bag made of elastic or collapsible material. This flexible container can be compressed during transport to reduce volume and can expand to accommodate the full filter surface area during operation, while also adapting to different vacuum cleaner configurations.
Solution Approach 2:
The flexible bag transitions from a compressed state during transport/storage to an expanded state during operation, allowing the filter cartridge to achieve its full filter surface area when needed while maintaining compact dimensions when not in use.
3Stability of the object's composition
If a rigid cartridge container is used, then the cartridge is securely held, but the interior volume is limited and does not allow for good collection of leaves and other bulky debris
Solution Approach 1:
The flexible bag serves as the container that holds both the filter cartridge and collected debris. The bag can expand to accommodate bulky debris like leaves while maintaining secure positioning of the filter cartridge through internal structural elements or attachment mechanisms.
Solution Approach 2:
The flexible bag combines multiple functions: it serves as the container for the filter cartridge, the collection bag for debris, and the structural element that provides both stability and expandability. This merging of functions eliminates the need for separate rigid containers.
4Productivity
If a cartridge with large internal diameter is used to contain leaves, then the evacuation section is not restricted, but the cartridge is very bulky and penalizes manual movement
Solution Approach 1:
The flexible bag allows the filtration system to have a large effective volume for debris collection and adequate evacuation section when expanded during operation, while compressing to a compact, lightweight form during transport that does not impede manual movement of the vacuum cleaner.
Solution Approach 2:
The system dynamically changes volume between operational state (expanded for maximum debris capacity and suction flow) and transport state (compressed for ease of movement), allowing it to optimize both suction performance and portability at different times.
