Oral Care Implement with Embedded Decorative Elements in Translucent Shell

Solution Overview

Problem

The oral care implement industry faces challenges in reducing manufacturing costs while enhancing aesthetics, as current methods involving multiple mold cavities or components increase time and expense.

Innovation Solution

A base structure comprising a core component and a shell component, where the shell component is made of a translucent material, encapsulating the core component with embedded decorative elements, visible through the shell, to achieve a desirable aesthetic effect while simplifying design and manufacturing.

1Shape

If multiple mold cavities or multiple components are used to enhance aesthetics, then the visual appeal of the oral care implement is improved, but the manufacturing time and cost increase

Engineering Contradiction:
Core Design Contradiction:
ShapeVSProductivity

Solution Approach 1:

The patent combines multiple aesthetic features (decorative elements, translucency effects, embedded particles) into a single integrated base structure formed by one mold cavity. This merging approach achieves complex visual appeal while maintaining manufacturing efficiency, as the entire base structure with all decorative features is produced in a single molding operation rather than requiring multiple components or cavities

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The base structure utilizes composite material features by incorporating decorative elements (such as particles, flakes, or other aesthetic additives) within the translucent or transparent material matrix. This composite approach allows the single base structure to exhibit multiple aesthetic properties simultaneously, resolving the contradiction between visual appeal and manufacturing simplicity

If multiple mold cavities or components are used to enhance aesthetics, then the visual appeal of the oral care implement is improved, but the manufacturing cost increases

Engineering Contradiction:
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The patent merges multiple aesthetic functions into a single base structure that can be manufactured in one mold cavity, eliminating the need for multiple components that would require separate manufacturing and assembly processes. This reduces tooling costs, labor costs, and overall manufacturing complexity while maintaining enhanced visual appeal

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

By using composite materials with decorative elements embedded in the base structure material, the patent achieves complex aesthetic effects within a single manufacturing process. This eliminates the need for multiple production steps or expensive post-assembly operations, thereby reducing manufacturing costs while maintaining high aesthetic value

AI summary

An implement having a base structure with a core component and a shell component that surrounds the core component. The core component may include a body formed of a rigid material and decorative elements embedded within the body. The shell component may be formed of a substantially transparent material so that the decorative elements of the core are visible through the shell component.
