Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic models fail to replicate the realistic surface state of iron rust, leading to an inferior appearance that lacks the authenticity and realism desired by enthusiasts, particularly in military-related models.
Innovation Solution
A plastic model with an iron-coated layer on its base material, allowing for varying states of rust generation and progression through paint film application and scratching, mimicking the natural corrosion of iron, enabling a more realistic and customizable appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If paint films or chemical conversion treatments are applied to plastic model surfaces, then the model can be colored to resemble metal, but the surface state differs from real material and looks cheap at close distance
Solution Approach 1:
The patent applies a metal coating layer on the plastic model surface that replicates the actual metal surface state, including rust patterns and corrosion characteristics. This copying approach creates a realistic metal appearance that closely matches the target object, resolving the contradiction between applying coating and achieving realistic surface state.
2Shape
If red powder is sprinkled and adhered to the surface to create rust appearance, then the model can show rust color, but the surface state differs from real material and is inferior to reality
Solution Approach 1:
Instead of using loose red powder, the patent uses a metal coating layer that is actually deposited and adhered to the plastic surface. This creates genuine rust patterns through controlled corrosion or rust-effect treatment of the metal coating itself, producing authentic rust texture and appearance rather than merely simulating it with loose powder.
Solution Approach 2:
The patent combines plastic base material with a metal coating layer to create a composite structure. This allows the model to have the ease of plastic manufacturing while achieving the realistic metal surface state and rust appearance of actual metal materials, resolving the contradiction between material ease and surface realism.
3Shape
If static paint film or rust powder is applied to the model surface, then the model achieves metal-like appearance, but it cannot change over time like real iron rust progression
Solution Approach 1:
The patent creates a dynamic rust progression system where the metal coating layer can be selectively treated to show different stages of rust development. By controlling where rust patterns form and how they progress on the metal coating surface, the model can dynamically change appearance over time or through user interaction, mimicking real iron corrosion processes rather than remaining static.

AI summary
To provide a plastic model that can achieve a realistic surface state by actual iron rust or the like appearing on an iron-coated component surface and a method of manufacturing the plastic model, and a plastic model component thereof and a method of manufacturing the plastic model component. The above-described problem is solved by a plastic model (20) assembled using a component (10) including a base material (1) and at least an iron-coated layer (2) provided on the base material (1) as some or all components. The iron-coated layer (2) may be provided directly on the base material (1), may be provided between the base material (1) and a paint film (3), or may be provided as an outermost surface layer on the base material (1) or on the paint film (3) on the base material (1) provided as necessary on the base material (1). The iron-coated layer (2) is a pure iron-coated layer or an iron alloy-coated layer, and may contain a dispersing material.
