Thin Glass Laminate Interval Control for Shock Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional glass sheet laminates do not adequately meet the demands for advanced properties such as shock resistance, crime prevention, heat shock resistance, translucency, and airtightness, as mere improvements in strength and thermal performance are insufficient for modern applications.
Innovation Solution
A glass sheet laminate structure is developed by laminating at least three glass sheets with a thickness of less than 1 mm through an intermediate layer, where the maximum variation in the interval between adjacent glass sheets is controlled between 0 μm and 200 μm, providing a buffer effect and enhanced adhesiveness, resulting in high strength and nonlinear elasticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glass sheets are laminated through an intermediate layer, then shock resistance and crime prevention performance are improved, but manufacturing precision control becomes more difficult
Solution Approach 1:
The patent applies parameter changes by controlling the interval H between glass sheets within a specific range (0 μm to 200 μm) to optimize both shock resistance and manufacturing precision. By defining this parameter range, the patent resolves the contradiction between improving reliability through lamination and maintaining manufacturing precision, as the controlled interval ensures adequate buffer for shock absorption while remaining feasible for precise manufacturing.
2Reliability
If the interval between glass sheets is increased to provide buffer effect, then shock resistance is improved, but adhesiveness and structural stability deteriorate
Solution Approach 1:
The patent uses parameter changes by optimizing the interval H between glass sheets within the range of 0 μm to 200 μm. This controlled parameter change provides sufficient buffer space for shock resistance while maintaining adequate adhesiveness, resolving the contradiction between these two opposing requirements through precise parameter specification.
Solution Approach 2:
The intermediate layer serves as a mediator between glass sheets, enabling the patent to achieve both shock resistance and adhesiveness. The intermediate layer fills the interval H between glass sheets, providing cushioning for shock absorption while maintaining structural bonding, thus resolving the contradiction between buffer effect and adhesiveness.
3Strength
If multiple glass sheets are laminated to enhance strength, then durability against external impacts is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the glass structure into multiple thin glass sheets (each less than 1 mm thick) laminated together. This segmentation approach enhances durability against external impacts through multiple layers while managing complexity by using standardized thin sheets with a controlled interval, making the multi-layer structure more manageable than using fewer thick sheets.
