Non-Woven Pet Water Filter Cartridge to Eliminate Plastic Trays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet water filter cartridges rely on plastic skeletons or trays that are costly, non-functional, difficult to recycle, and prone to anaerobic bacterial growth, leading to inefficient filtration and environmental waste.
Innovation Solution
A pet water filter cartridge composed of a non-woven cotton hot pressed base and cover, with accommodation chambers for filter materials like bulk exchange resin or activated carbon, eliminating plastic components and enhancing filtration efficiency and ease of cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plastic skeleton or tray carrier is used as filter cartridge carrier, then structural support is provided, but cost increases and filtering function is lost
Solution Approach 1:
The patent merges the structural support function and the filtering function into a single component by making the carrier itself from non-woven fabric material that possesses both mechanical strength and filtering capability, eliminating the need for separate plastic skeletons or trays
Solution Approach 2:
The non-woven fabric carrier serves multiple functions simultaneously: it provides structural support, acts as a filtering medium, and enables easy disassembly for waste separation, replacing the single-function plastic carrier
2Strength
If plastic skeleton or tray carrier is used, then structural support is provided, but material waste increases and environmental impact worsens
Solution Approach 1:
The patent enables easy separation and recovery of different materials by designing the carrier as a hot-pressed non-woven fabric structure that can be disassembled, allowing filter materials to be recovered and the fabric carrier to be disposed of separately, improving waste classification
3Ease of operation
If filter material is enclosed between plastic shell and non-woven fabric, then packaging is achieved, but anaerobic bacterial growth occurs and filtration efficiency decreases
Solution Approach 1:
The patent removes the plastic shell enclosure from the filter cartridge structure, allowing the filter material to be directly exposed to aerobic environment while still providing necessary support through the non-woven fabric carrier, thereby preventing anaerobic bacterial growth
Solution Approach 2:
The patent uses uniform non-woven fabric material throughout the carrier structure, ensuring consistent porosity and permeability that maintains good filtration performance while allowing proper air circulation to prevent anaerobic conditions
4Strength
If non-woven fabric and plastic skeleton are combined through hot pressing or ultrasound, then structural integrity is achieved, but separation becomes difficult and waste handling worsens
Solution Approach 1:
The patent segments the filter cartridge into distinct components: the hot-pressed non-woven fabric carrier and the filter materials, allowing easy separation for waste classification while maintaining structural integrity during use through the hot-pressing process
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 solution achieves fast and efficient filtration with reduced environmental impact by using all-filtering material construction, easy cleaning, and minimized plastic waste, improving hygiene and cost-effectiveness.
Implementation Method 1
After the water passes through the first layer of filtering cotton, larger substances are filtered out
Implementation Method 2
the filtering material can be directly impacted in sufficient space, the filtering material is caused to rotate and move in the water
Implementation Method 3
the filter material is a bulk exchange resin, activated carbon or zeolite
Implementation Method 4
The water filter cartridge carrier is composed of a non-woven cotton hot pressed base and a non-woven cotton cover
Implementation Method 5
the non-woven cotton cover is sealed at the opening of the accommodation chamber by hot pressing or ultrasonic sealing
