Glass-Blown Embedded Decorative Structure for Shape-Diverse Products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current glass products lack diversity in shape, material, and decorative effect, and cannot achieve a blown glass embedded decorative structure.
Innovation Solution
A glass embedded product is created by forming a base with cavities and holes, where a glass-blown lining is formed inside the cavity and protruding decorative parts are embedded in the holes, forming an integral structure through once blow molding, with a removable protective glue layer used to create gaps for an adhesive layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional glassblowing methods are used, then glass products can be manufactured, but the shape and material are monotonous and decorative effect is limited
Solution Approach 1:
The glassblowing process is segmented into distinct functional zones: a cavity for forming the glass-blown lining and multiple holes for forming protruding decorative parts. This segmentation allows different shapes and materials to be created simultaneously in different regions, resolving the contradiction between shape diversity and process complexity.
Solution Approach 2:
The base structure serves multiple functions: it provides a cavity for the glass-blown lining, contains holes for protruding decorative parts, and acts as the final product container. This multi-functionality enables diverse shapes and materials without requiring separate manufacturing processes for each feature.
2Temperature
If glassblowing is performed without protective coating, then the process is simpler, but the base cannot withstand high glass melting temperature
Solution Approach 1:
A removable protective glue layer is applied to the base before glassblowing to protect it from high temperatures. This preliminary protective action enables the base to withstand the glass melting temperature, and the protective layer can be removed afterward without complicating the overall manufacturing process.
Solution Approach 2:
The removable protective glue layer acts as an intermediary between the base and the molten glass. It protects the base from direct contact with high-temperature molten glass, allowing the base material to withstand temperatures it would normally cannot tolerate.
3Stability of the object's composition
If glass-blown lining is formed without gaps, then the structure is more compact, but thermal expansion differences cause deformation
Solution Approach 1:
Gaps are intentionally created at specific locations between the glass-blown lining and the base, rather than uniformly throughout. These localized gaps accommodate thermal expansion differences where needed, while maintaining structural stability in other regions. The gaps are positioned to handle expansion without compromising overall structural integrity.
4Strength
If adhesive layer is added to fill gaps, then the bonding strength is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The removable protective glue layer serves dual purposes: it protects the base during glassblowing and, when removed, creates spaces that are subsequently filled with adhesive layer to strengthen bonds. This self-service approach integrates protection and bonding functions into a single initial coating step, improving bonding strength without significantly increasing process complexity.
