Integrally Molded Transparent Plastic Goblet to Eliminate Joint Marks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing goblet manufacturing methods using plastic materials face challenges in maintaining appearance integrity due to visible joint marks from connection structures or high-frequency heating, leading to complex processes and reduced product yield.
Innovation Solution
A transparent plastic goblet is developed with a cup-shaped part, columnar leg, and disc-shaped base integrally molded from transparent plastics, where the bottom edge of the cup forms the leg and base, featuring a unique internal space and ring frame design that allows for stable configuration and easy manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If connection structures are used to combine the cup, leg and base, then the goblet can be assembled, but the integrity of appearance is ruined due to visible joint marks
Solution Approach 1:
The patent merges the cup, leg and base into a single integrally molded piece, eliminating separate connection structures and their associated joint marks. The molding process creates continuous material flow between components, ensuring appearance integrity while maintaining structural functionality.
Solution Approach 2:
The integrally molded goblet is designed with distinct functional segments (cup, leg, base) that are visually separable but structurally continuous. The molding process creates natural transitions between segments without requiring separate connection structures, achieving both assembly-like functionality and appearance integrity.
2Ease of manufacture
If high frequency heating is used to bond the cup, leg and base, then the components can be joined, but joint marks are formed at the interfaces which are visually detected
Solution Approach 1:
The patent combines the molding process to create continuous material flow between the cup, leg and base, eliminating the need for separate bonding operations. This integral molding approach prevents joint mark formation while maintaining the bonding functionality through the molding process itself.
3Ease of manufacture
If the cup, leg and base are molded respectively and combined using connection structures or high frequency heating, then the goblet can be manufactured, but the overall process becomes complex
Solution Approach 1:
The patent merges multiple manufacturing operations into a single integrally molded process. Instead of separate molding and bonding operations, the cup, leg and base are formed in one continuous molding process, significantly simplifying the manufacturing process while maintaining production capability.
4Illumination intensity
If transparent material is used for the goblet, then aesthetic appearance is achieved, but joint marks from bonding processes are likely to be visually detected
Solution Approach 1:
The patent uses integral molding with transparent material to create continuous material flow without discrete joints. This eliminates joint marks that would be visible through the transparent material, allowing the aesthetic benefits of transparency to be fully realized while maintaining appearance integrity.

AI summary
A transparent plastic integrally molded goblet has a cup-shaped part, a columnar first leg and a disc-shaped first base integrally molded from transparent plastics. The bottom edge of the cup-shaped part extends downwards to form the first leg. The bottom end of the first leg integrally forms the first base. The cup-shaped part has a circumferential wall which encloses the circumference of a first space. The top edge of the circumferential wall forms an annular first ring frame, and the central part of bottom edge of the first base downwards forms a first convex pin. The integral molding of transparent plastics can enhance the appearance integrity of the goblet, the manufacture of the goblet is easy and the product yield is increased.
