Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a continuing unmet need for interlayers and related laminated glass constructions that provide new and improved decorative effects, visual impressions, attractiveness, aesthetics, and visual noise creation while maintaining the quality, safety, and performance attributes required in laminated glass applications.
Innovation Solution
The development of an interlayer for laminated composite glazings that includes a polymer resin composition and deformable, visible, light-reflecting body precursors. These precursors deform to form cupped, visible, light-reflecting bodies when the interlayer is laminated between transparent substrates, creating a decorative and aesthetically appealing effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional interlayers with uniform composition are used, then manufacturing simplicity is maintained, but decorative effect and visual appeal are insufficient
Solution Approach 1:
The interlayer is segmented into multiple distinct layers including a first interlayer with light-reflecting bodies, a second interlayer with different optical properties, and optionally a third interlayer. This segmentation allows each layer to contribute different decorative functions while maintaining overall manufacturing simplicity through standardized lamination processes.
Solution Approach 2:
The invention uses composite interlayer structures combining different material types and optical properties in a single laminated assembly. The composite nature allows integration of light-reflecting bodies, transparent regions, and colored regions within one interlayer system, enhancing decorative versatility without requiring multiple separate glass assemblies.
2Adaptability or versatility
If light-reflecting bodies are added to the interlayer, then decorative effect is improved, but manufacturing complexity increases
Solution Approach 1:
Light-reflecting bodies are pre-formed and positioned within the first interlayer before final lamination. This preliminary action allows complex decorative features to be prepared in advance using simpler processes, reducing the complexity of the final lamination step while maintaining high decorative effect.
Solution Approach 2:
The light-reflecting bodies can be created as replicas or copies of desired decorative patterns. These copied features are then integrated into the interlayer structure, allowing complex decorative effects to be achieved through replication rather than direct formation, thereby reducing manufacturing complexity.
3Adaptability or versatility
If deformable precursors are used to create cupped light-reflecting bodies, then visual noise and aesthetic appeal are improved, but manufacturing precision requirements increase
Solution Approach 1:
The precursors are designed to change their physical parameters (shape, volume) in response to lamination conditions such as heat and pressure. By controlling the deformation parameters through standardized lamination cycles, the desired cupped shapes are achieved with consistent visual noise effects without requiring ultra-precise manufacturing control.
Solution Approach 2:
The deformable precursors self-transform into cupped light-reflecting bodies during the lamination process itself. The precursors automatically deform under the applied heat and pressure to create the desired three-dimensional cupped shapes, eliminating the need for separate forming operations and reducing overall manufacturing precision requirements.
