Transparent Pane With Dual-Plane Patterns for Bird Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transparent glass panes are not effectively recognized by birds, leading to bird strikes, and existing solutions compromise between efficiency and transparency or are not effective for all bird species.
Innovation Solution
A transparent pane with optically effective patterns in two spaced planes, creating dynamic scenery or Moiré effects that enhance visibility to birds, utilizing their better spatial resolution and sensitivity to dynamic processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single optically effective pattern is applied to the glass pane, then the pattern is visible to birds, but the transparency for humans is compromised or the effect is insufficient
Solution Approach 1:
The single pattern is divided into multiple pattern elements arranged in different planes (first plane and second plane spaced apart in the thickness direction). Each plane contains pattern elements that individually provide limited visual effect, but collectively create enhanced dynamic visibility to birds while maintaining human transparency.
Solution Approach 2:
The pattern extends from a two-dimensional surface application into the third dimension by spacing pattern elements apart in the thickness direction of the pane. This creates depth and enables dynamic visual effects as birds approach, improving bird detection without compromising human viewing transparency.
2Reliability
If static patterns are used, then the pattern provides consistent visibility, but birds with good dynamic vision perception may not detect it effectively
Solution Approach 1:
The static patterns in different planes create dynamic visual effects as birds approach the pane. The spatial arrangement causes pattern elements to shift relative to each other during bird approach, generating seemingly dynamic effects including scenery effects and Moiré effects that exploit birds' keen dynamic vision perception.
Solution Approach 2:
The spaced arrangement of pattern elements in multiple planes creates periodic visual variations as birds approach. The relative shifts between pattern elements produce repeating visual patterns and Moiré effects that enhance detectability for birds with sensitive dynamic vision.
3Productivity
If fine patterns are applied (as in EP 1479294), then human aesthetic concept is preserved, but the effect may be insufficient for all bird species
Solution Approach 1:
The pattern elements are designed with specific optical properties that differ from the surrounding glass. The spaced arrangement in multiple planes creates localized optical effects that are subtle to humans (preserving aesthetics) but highly visible to birds with superior spatial resolution and dynamic vision.
Solution Approach 2:
The solution combines multiple pattern layers in different planes, creating a composite optical structure. This multi-layer composite approach enhances the visual effect for birds while maintaining aesthetic transparency for humans, as the combined effect of spaced patterns creates dynamic visibility only detectable by approaching observers.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly improves bird strike protection by making the glass more recognizable to birds through dynamic patterns, maintaining transparency for humans.
Implementation Method 1
relative shifts of the pattern elements with respect to one another result which can cause seemingly dynamic effects (scenery effect, Moiré effect) during the approach
Implementation Method 2
a cooperation of the patterns results beyond the pattern effect of the individual patterns such that macroscopic patterns are present or are produced or disappear again
