Solution Overview

Problem

Existing glue sticks on the market are limited in color variety, lack attractiveness, and do not cater well to children's preferences, failing to meet market demand for more vibrant and engaging adhesive products.

Innovation Solution

The development of a glitter glue stick comprising specific components such as deionized water, propylene glycol, glycerin, adhesive, defoamer, excipient, caustic soda, preservative, pigment, and glitter, with controlled ratios and treatment of glitter with a silane coupling agent to enhance its properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If traditional white or transparent glue stick formulations are used, then the adhesive function is maintained, but the appearance is dull and unattractive to children

Engineering Contradiction:
Improveappearance brightness and colorfulnessVSAvoidformulation complexity
Core Design Contradiction:
Illumination intensityVSEase of manufacture

Solution Approach 1:

The patent combines traditional adhesive materials (PVA, starch, or polyacrylic resin) with glitter particles and pigments to create a composite glue stick formulation. This composite approach maintains the adhesive functionality while adding visual appeal through the embedded reflective glitter and colored pigments, directly resolving the contradiction between appearance brightness and formulation complexity.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent introduces pigments and glitter as color-enhancing additives to transform the traditional white or transparent appearance into vibrant, multi-colored formulations. The glitter provides reflective sparkle while pigments add base coloration, creating an appealing visual appearance that attracts children without compromising the adhesive base formulation.

Inventive Principle:
Principle #32Color changes

2Adaptability or versatility

If more colors and visual effects are added to attract children, then the appeal and interestingness improve, but the product complexity and production difficulty increase

Engineering Contradiction:
Improvecolor variety and visual appealVSAvoidproduct formulation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By formulating a composite glue stick that integrates multiple functional components (adhesive base, glitter, pigments, preservatives) into a single homogeneous mixture, the patent achieves color variety and visual appeal without requiring multiple separate products. This composite approach simplifies the overall product system while maintaining diverse visual characteristics.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The glue stick formulation serves multiple functions simultaneously: it provides adhesive bonding, visual appeal through glitter and color, and stability through preservatives. This multi-functionality allows a single product to satisfy diverse consumer requirements (adhesion, aesthetics, safety) without increasing the number of separate products needed.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Illumination intensity

If glitter and pigments are added to create shiny and colorful effects, then the coating effect and appearance improve, but the formulation stability and manufacturing precision become more challenging

Engineering Contradiction:
Improveshining and coating effectVSAvoidformulation uniformity and stability
Core Design Contradiction:
Illumination intensityVSManufacturing precision

Solution Approach 1:

The patent specifies precise parameter ranges for each component (adhesive 15-40%, glitter 1-10%, pigments 0.1-5%, preservatives 0.1-0.5%) to optimize the balance between visual effect and formulation stability. By controlling these parameters within defined ranges, the patent ensures consistent mixing, uniform distribution of glitter and pigments, and stable product performance during manufacturing.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent ensures uniform distribution of glitter and pigment particles throughout the adhesive matrix by controlling the mixing process and particle size. This local quality approach ensures that every portion of the glue stick contains consistent concentrations of visual effect components, achieving uniform shining and coating effects without aggregation or settling issues.

Inventive Principle:
Principle #3Local quality
