Suction Nozzle with Resilient Elastomer Projections for Textile Hair Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction nozzles for vacuum cleaners are inefficient in removing animal hairs from textile surfaces, requiring repeated passes and being messy and time-consuming due to adherence issues between hair and carpeting.
Innovation Solution
A suction nozzle with resilient, elastomer-coated projections that bend away from the surface during sweeping, forming a passage to guide hair towards airflow inlets, ensuring effective hair accumulation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional suction nozzles are used to remove animal hairs from textile surfaces, then the vacuum cleaner can be operated, but the hairs adhere strongly to the carpeting requiring repeated passes and the nozzle filaments become clogged requiring messy cleaning
Solution Approach 1:
The projections are made resilient and bendable so they dynamically adapt during sweeping motion - bending away from the surface to accumulate hair, then rebounding to their initial position. This dynamic behavior enables effective hair collection without clogging, eliminating the need for repeated passes and nozzle cleaning maintenance
Solution Approach 2:
The projections are made from elastomer material with specific Shore A hardness (40-70), creating optimal mechanical properties that balance resilience for bending during sweep and rigidity for effective hair engagement. This parameter optimization enables single-pass effective hair removal
2Productivity
If the projections are made resilient and bendable to accumulate hair, then hair removal effectiveness improves, but the structural complexity of the nozzle increases
Solution Approach 1:
The projections are constructed as flexible elastomeric elements that can bend and rebound. This flexibility allows them to accumulate hair effectively during sweeping while maintaining a relatively simple overall nozzle structure without complex mechanical components
Solution Approach 2:
The projections use composite construction with a resilient core material (elastomer with Shore A 40-70 hardness) that provides both the necessary bendability for hair accumulation and structural integrity. This material composite approach achieves complex functional behavior with relatively simple projection geometry
3Strength
If the projections are made from hard material to withstand prolonged use, then durability improves, but they may damage the textile surface and lose resilient bendability
Solution Approach 1:
The projections use elastomer material with Shore A hardness specifically controlled in the range of 40-70. This parameter range provides optimal balance - hard enough to withstand prolonged use and engage hair effectively, yet soft enough to bend resiliently without damaging textile surfaces
Solution Approach 2:
The projections may use composite construction with a resilient core material providing durability and structural integrity, while the elastomer coating provides the soft, non-damaging surface that can bend and rebound without harming the textile. This composite approach separates the durability function from the surface interaction function
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 nozzle quickly and thoroughly removes animal hairs from textiles by rolling them into elongate rolls and guiding them into the vacuum cleaner, reducing the need for repeated passes and minimizing mess.
Implementation Method 1
The plurality of projections are resilient bendable, which plurality of projections are so mounted on the second face that when they are brought into contact with the textile surface to be cleaned during a sweeping motion, they are bent away from their initial position
Implementation Method 2
when said projections lose contact with said textile surface, said projections rebound to their initial position
Implementation Method 3
one or more inlets for airflow; wherein the plurality of parallel rows are mounted on the second face of the base section so as to define a passage running from the outer edge towards the one or more inlets for airflow
