Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional artificial eyes used in taxidermy lack realism due to their expressionless and unconvincing appearance, requiring significant artistic skill and time to achieve realistic coloration and details.
Innovation Solution
An artificial eye design featuring a transparent cup-shaped body with a concave inner surface and convex outer surface, including a pupil portion, annular iris portion, and grooves on the inner surface to reflect light, combined with coloration techniques using glazes that are fired to create a natural appearance and depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional hand-painted glass eyepieces are used, then artistic skill and time are required to create realistic coloration, but the resulting eyes still lack realism due to being expressionless and lacking intricate details
Solution Approach 1:
The artificial eye is divided into multiple distinct components: a colored iris insert with detailed patterns, a transparent cornea layer with refractive grooves, and a scleral base. This segmentation allows each component to be manufactured separately with optimized techniques and then assembled, achieving high realism without requiring the entire manufacturing process to be overly complex
Solution Approach 2:
A transparent cornea layer with grooves is introduced as an intermediary component between the iris insert and the external environment. This cornea layer acts as a mediator that refracts and diffuses light passing through it, creating realistic optical effects and enhancing the overall realism of the artificial eye without requiring direct painting or detailing of the entire eye structure
2Productivity
If conventional artificial eyes are used, then manufacturing time is reduced compared to hand-painted eyes, but the eyes lack natural coloration and appearance
Solution Approach 1:
The iris insert is pre-manufactured with detailed coloration, patterns, and textures using techniques such as printing, molding, or layering before being assembled into the final eye. This preliminary action allows complex coloration work to be done in advance using efficient manufacturing methods, rather than requiring time-consuming hand-painting during final assembly
Solution Approach 2:
The cornea layer incorporates grooves with specific geometric parameters (depth, spacing, curvature) that are optimized to refract and diffuse light in ways that mimic natural corneal optics. By carefully controlling these geometric parameters, realistic optical effects are achieved through a relatively simple transparent layer rather than requiring complex painted details
3Ease of manufacture
If simple transparent cup-shaped bodies are used, then manufacturing is simplified, but the eyes lack depth and light-refracting properties of natural eyes
Solution Approach 1:
While the overall eye structure maintains a simple transparent cup shape for ease of manufacture, local quality is enhanced by adding grooves to the cornea layer and using a multi-layered iris insert with varying transparency, coloration, and texture. These localized enhancements provide depth and light-refracting properties in specific areas without complicating the entire manufacturing process
Solution Approach 2:
The artificial eye uses composite construction with a transparent cornea material, a colored iris material with optical properties, and a scleral base material. Each material is selected for its specific optical and aesthetic properties, and their combination creates depth and light-refracting effects that would be difficult to achieve with a single homogeneous material

AI summary
An artificial eye comprises a transparent cup-shaped body member having a substantially concave inner surface and a substantially convex outer surface. The body member includes a pupil portion at the center, a substantially annular iris portion abutting the peripheral edge of the pupil portion for defining a boundary between the pupil portion and the iris portion, and at least one groove formed in the concave inner surface of the iris portion of the body member. The grooves are visible through the iris portion for reflecting light through the body member.
