Biodegradable Disposable Debris Bag for Pool Cleaners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reusable debris bags for pool cleaners require tedious cleaning and can spill debris back into the pool, while disposable bags save time but often restrict water flow, reducing debris pickup efficiency.
Innovation Solution
A biodegradable disposable debris bag with a sheet of filtration media having a specific permeability and an attachment fixture that allows for efficient coupling to the pool cleaner, ensuring effective debris capture and easy disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If reusable debris bags are used, then debris can be captured and reused, but cleaning becomes tedious and debris may spill back into the pool
Solution Approach 1:
The patent employs disposable debris bags made from biodegradable materials that are discarded after single use, eliminating the cleaning process entirely. The bag is thrown away with the debris after capturing pool debris, avoiding the tedious cleaning task and potential spill-back issues associated with reusable bags.
Solution Approach 2:
Instead of cleaning and reusing the debris bag, the system discards the entire bag with the captured debris after it serves its purpose. This approach trades the effort of cleaning against the benefit of reliable debris containment, choosing disposal over recovery for improved reliability.
2Loss of time
If disposable debris bags are used, then maintenance time is reduced, but water flow may be restricted reducing debris pickup efficiency
Solution Approach 1:
The disposable debris bag is constructed from porous biodegradable materials that allow water to flow through freely while capturing debris. The porous structure maintains adequate water permeability to prevent flow restriction, ensuring the pool cleaner maintains its debris pickup efficiency despite using a disposable rather than reusable bag.
Solution Approach 2:
The patent specifies particular parameters for the biodegradable material including permeability between 900-1200 cfm/ft2, which is optimized to balance water flow requirements with debris capture capability. This parameter optimization ensures that the disposable bag does not restrict water flow and maintains pool cleaner productivity.
3Loss of time
If conventional disposable bags are used, then time is saved, but environmental impact increases due to non-biodegradable materials
Solution Approach 1:
The patent changes the material parameter from conventional non-biodegradable plastics to biodegradable materials that decompose naturally in the environment. This material substitution maintains the time-saving benefits of disposable bags while eliminating the environmental harm, as the bag breaks down harmlessly after use rather than persisting as pollution.
Solution Approach 2:
The invention converts the typically harmful disposable plastic bag into a beneficial environmental solution by using biodegradable materials. The bag maintains the convenience of disposable use but adds the benefit of environmental friendliness, turning a harmful single-use plastic into a harmlessly degradable alternative.
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 biodegradable debris bag captures debris efficiently while allowing unimpeded water flow, reducing maintenance effort and environmental impact, and degrades harmlessly over time.
Implementation Method 1
a sheet of filtration media that forms an opening and a hollow interior portion to capture debris from the pool cleaner
Implementation Method 2
The filtration media has a permeability between about 900 cfm/ft2 and about 1,200 cfm/ft2
