Skin Ski Cleaning Composition Using Dibasic Esters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning compositions containing aliphatic and aromatic hydrocarbons for skin ski strips detach the adhesive, leading to damage, as they dissolve the attachment between the skin strips and the ski base.
Innovation Solution
A composition comprising C1-6 alcohols and dibasic esters, substantially free of aliphatic and aromatic hydrocarbons, effectively removes hydrophobic compounds like oils, resins, and waxes from skin strips without detaching them from the ski base, utilizing a mixture of solvents such as ethanol, dibasic esters like dimethyl succinate, and additives like alkoxyalkanols and tri(C1-6)alkanolamines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If conventional cleaning compositions containing aliphatic and aromatic hydrocarbons are used, then hydrophobic compounds such as oils, resins, grease, and waxes are removed from skin strips, but the adhesive attaching the skin strips to the ski base is dissolved, leading to detachment and damage
Solution Approach 1:
The patent changes the chemical composition parameters of the cleaning agent by replacing aliphatic and aromatic hydrocarbon solvents with a specific formulation containing C1-6 alcohols (60-90% by weight) and dibasic esters (10-30% by weight). This parameter change allows the cleaner to effectively remove hydrophobic compounds while maintaining adhesive integrity, as the new composition does not dissolve the adhesive bonding the skin strips to the ski base.
Solution Approach 2:
The patent employs a composite cleaning composition formulated with multiple components: C1-6 alcohols (such as ethanol, propanol), dibasic esters (such as dimethyl succinate, dimethyl glutarate, dimethyl adipate), and optional additives (alkoxyalkanols, tri(C1-6)alkanolamines). This composite material approach creates a synergistic effect where the combination of components provides both effective cleaning of hydrophobic substances and protection of the adhesive bond, resolving the contradiction between cleaning power and adhesive preservation.
2Productivity
If aliphatic and aromatic hydrocarbon solvents are used for cleaning, then cleaning effectiveness against hydrophobic dirt is improved, but the skin strips detach from the ski base causing damage
Solution Approach 1:
The patent modifies the chemical parameters of the cleaning solution by eliminating aliphatic and aromatic hydrocarbon solvents and substituting them with a controlled formulation of C1-6 alcohols and dibasic esters. This parameter change maintains or improves cleaning effectiveness against hydrophobic dirt while eliminating the harmful effect of adhesive dissolution and subsequent skin strip detachment, thereby preventing damage to the ski.
Solution Approach 2:
The patent converts the potential harm of solvent-based cleaning into a beneficial outcome by selecting specific solvents (C1-6 alcohols and dibasic esters) that have the dual property of effectively dissolving hydrophobic contaminants while being gentle enough not to affect the adhesive. This transforms the cleaning process from a potentially damaging operation into a protective maintenance activity.
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 composition effectively cleans skin strips by removing build-up dirt without detaching the strips from the ski base, ensuring continued grip and smooth sliding, while maintaining the adhesive integrity.
Implementation Method 1
a composition comprising (a) alcohol(s) and (b) dibasic ester(s) and being substantially free of any aliphatic and aromatic hydrocarbon solvents avoids detachment of the skin strips from the ski base but removes any build-up dirt such as those selected from oils, resins, grease, and waxes from the surface of the skin strip
