Transparent Solid Marker Gel Composition for Low Writing Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid portrayal materials, such as pastel crayons and pastels, face issues with high writing resistance, difficulty in maintaining transparency, and susceptibility to breaking or bending, leading to spreading and remnants on surfaces.
Innovation Solution
A transparent solid marker is developed by mixing a gel forming material containing an alkali metal or ammonium salt of aliphatic carboxylic acid with a transparency agent, hydrogenated glucose syrup, basic pigment, and oil, which enhances stick strength, reduces writing resistance, and prevents spreading, while maintaining transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a mixing ratio of the gelating agent is increased to increase hardness, then stick strength is improved, but softness as the stick is reduced and it is easily bent, and the sense of smooth writing is reduced
Solution Approach 1:
The patent changes the chemical composition parameters by introducing specific transparency agents (alkoxylated nitrogen compounds) and subsidiary transparency agents (saccharides, glycols, polyalcohols) in optimized ratios. This allows achieving both high stick strength and smooth writing sensation by modifying the molecular structure and intermolecular forces within the gel matrix, rather than simply increasing gelating agent concentration.
Solution Approach 2:
The patent creates a composite gel system combining gelating agents with multiple transparency agents and subsidiary transparency agents. This composite structure provides both mechanical strength from the gel network and smooth writing properties from the lubricating effect of transparency agents, resolving the contradiction between hardness and writing smoothness.
2Strength
If a mixing ratio of the gelating agent is increased to increase hardness, then stick strength is improved, but the stick is easily bent
Solution Approach 1:
The patent modifies the compositional parameters by incorporating transparency agents and subsidiary transparency agents that affect the viscoelastic properties of the gel. These agents change the molecular mobility and energy dissipation characteristics, allowing the stick to maintain strength while improving flexibility and resistance to permanent deformation from bending.
3Illumination intensity
If transparency is achieved in solid portrayal material, then the content can be made transparent, but writing resistance increases and remnants occur after writing
Solution Approach 1:
The patent optimizes the concentration and molecular weight parameters of transparency agents and subsidiary transparency agents. This allows achieving transparency while controlling the viscosity and adhesion characteristics of the gel, preventing excessive residue deposition on the writing surface.
Solution Approach 2:
The patent uses water-soluble saccharides and glycols as subsidiary transparency agents that can easily dissolve and disperse, leaving minimal permanent residue. These agents act as temporary lubricants during writing that do not require fixing, reducing remnants compared to traditional fixing-solution-based transparent materials.
4Illumination intensity
If transparency is achieved in solid portrayal material, then the content can be made transparent, but the sense of smooth writing is reduced
Solution Approach 1:
The patent carefully adjusts the molecular structure and concentration parameters of transparency agents (alkoxylated nitrogen compounds) and subsidiary transparency agents. These parameter optimizations ensure the gel maintains appropriate softness and lubricity for smooth writing while achieving transparency, avoiding the hardness and roughness that would otherwise result from transparency-enhancing formulations.
