Artificial Teeth Packaging with Asymmetric Base for Upright Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging for artificial teeth fails to display them in a natural position, with color distortions and inefficient space usage, limiting visibility and mechanical protection.
Innovation Solution
The packaging features base and cover components with different heights, convex or arcuate terminations, and optional step-like sections, along with protruding webs for secure closure, allowing upright display and mechanical protection of the teeth, while being easy to manufacture and open.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If teeth are clamped horizontally between the dental strip and the cover, then the packaging structure is simple, but the natural representation of the teeth position is not possible
Solution Approach 1:
The patent transitions from horizontal clamping to vertical standing arrangement of teeth. The base part is designed with a recess that accommodates the teeth in an upright position, allowing them to stand vertically rather than being clamped horizontally. This dimensional change enables natural representation of teeth position while maintaining packaging simplicity.
Solution Approach 2:
The base part features an asymmetric design with a rear boundary that is higher than the front boundary, creating a sloped surface. This asymmetric configuration provides mechanical support for vertically standing teeth, allowing their natural orientation to be represented while the cover maintains a conventional symmetric form for easy closure.
2Shape
If teeth are arranged on a rectangular base structure in a grid dimension, then all teeth can be lined up, but a natural representation of the position with the artificial teeth is not possible and a lot of space is required
Solution Approach 1:
The base part incorporates a localized recess with specific geometric characteristics designed to accommodate teeth in a vertical standing position. This localized structural modification allows teeth to be arranged in a compact, space-efficient manner while maintaining their natural positional representation, eliminating the need for extensive rectangular grid arrangements.
3Shape
If the base part and cover have different height boundaries, then natural representation and clear visibility of teeth are enabled, but the manufacturing complexity increases
Solution Approach 1:
The base part is designed with asymmetric height boundaries, where the rear boundary extends higher than the front boundary. This asymmetric configuration creates a sloped surface that supports vertically standing teeth and enables their natural representation. The cover maintains a conventional form for easy manufacturing, while the base part's asymmetric design is achieved through standard molding techniques.
4Reliability
If protruding webs are arranged on the borders for mutual form-fitting plugging, then secure closure against displacement is ensured, but the device complexity increases
Solution Approach 1:
The closure mechanism is segmented into discrete protruding webs located at specific border positions of the base part and cover. These webs are distributed at strategic locations to provide form-fitting plugging that prevents displacement. This segmented approach achieves reliable closure without requiring a complex continuous interlocking structure, maintaining manufacturing simplicity.

AI summary
The case (1) has a base part (3) for receiving teeth, and a lid (4) placed upon the base part for covering the base part together with the inserted teeth, front and rear boundaries (7) of the base part having heights different from front and rear boundaries (8, 6) of the lid, where a large part of the rear boundary of the base part is embodied higher than the front boundary (7) of the base part. Protruding bars are arranged on the rear and front boundaries of the base part and the lid that comprises a clear or translucent plastic.
