Anionic Laundry Pre-rinse for Bedbug Egg Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for eliminating bedbug eggs from textiles and surfaces are inadequate due to the survival of bedbugs and their eggs during dryer heat exposure, necessitating additional effective and non-toxic treatment solutions.
Innovation Solution
A pre-rinsing method using a composition comprising anionic compounds such as alcohol sulfate, alkyl sulfonate, arylalkyl sulfonate, salt of a fatty carboxylic acid, or polycarboxylate polymer at a pH of about 7 to 9, which effectively reduces the viable population of bedbug eggs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heat drying in a laundry dryer is used to kill bedbugs and bedbug eggs, then some bedbugs and eggs are killed, but many bedbugs and eggs survive due to uneven heat and too short exposure
Solution Approach 1:
The patent applies preliminary action by treating textiles with a pesticidal composition before drying. The composition is applied to the textile surface in advance, allowing it to penetrate and kill bedbug eggs that would otherwise survive the drying process. This pre-treatment ensures that even eggs exposed to uneven or insufficient heat are already compromised by the chemical agent.
Solution Approach 2:
The patent changes parameters by using a specific pH range (7-9) and temperature range (100°F-140°F) for the pesticidal composition that optimizes egg-killing effectiveness while being safe for textiles. This parameter optimization ensures complete elimination of bedbug eggs without damaging the textile material, resolving the contradiction between killing effectiveness and process safety.
2Reliability
If pesticides are used to eliminate bedbugs and bedbug eggs, then the pest population is reduced, but toxic substances are introduced into the environment
Solution Approach 1:
The patent changes the chemical parameters of the pesticidal composition by using a mild pH range (7-9) and moderate temperature range (100°F-140°F), which are effective against bedbug eggs but non-toxic to humans and the environment. This parameter optimization allows the composition to be safe for use on textiles and in household environments while maintaining pest elimination effectiveness.
Solution Approach 2:
The patent employs a composition designed for single-use application that degrades after use, leaving no persistent toxic residues. The composition is formulated to be effective during the treatment process but breaks down into harmless substances afterward, eliminating long-term toxic environmental impact while maintaining pest control effectiveness.
3Object-affected harmful factors
If bedbug eggs are left untreated, then toxic pesticides are avoided, but the bedbug population persists and continues to infest textiles
Solution Approach 1:
The patent applies preliminary action by treating textiles with a pesticidal composition before drying. The composition is applied to the textile surface in advance, allowing it to penetrate and kill bedbug eggs that would otherwise survive the drying process. This pre-treatment ensures that even eggs exposed to uneven or insufficient heat are already compromised by the chemical agent.
Solution Approach 2:
The patent changes parameters by using a specific pH range (7-9) and temperature range (100°F-140°F) for the pesticidal composition that optimizes egg-killing effectiveness while being safe for textiles. This parameter optimization ensures complete elimination of bedbug eggs without damaging the textile material, resolving the contradiction between killing effectiveness and process safety.
