Light Absorbing Element Between Cellular Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cellular coverings for architectural openings face issues with light leakage through the connections between cells, which affects light blocking and insulative qualities, as light can pass through the adhesive lines or material gaps between adjacent cells.
Innovation Solution
Incorporating a light absorbing element at the interface between cellular units, which can be a dye, ink, or a separate dark-colored material, positioned to absorb light that would otherwise pass through the connections, ensuring minimal light transmission and enhanced insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cellular coverings are made with adhesive lines or material gaps between adjacent cells for structural connection, then ease of manufacture and device assembly are improved, but light blocking performance deteriorates as light can pass through these connections
Solution Approach 1:
A light-absorbing material is introduced as an intermediary element between adjacent cellular units. This material is positioned at the interface or connection region between cells and absorbs light that would otherwise pass through the connection, thereby eliminating light leakage while preserving the structural connection functionality
Solution Approach 2:
The light-absorbing material is applied locally at specific regions where light leakage occurs (interfaces between cellular units) rather than uniformly across the entire covering. This targeted approach addresses the light blocking problem at connection points while maintaining the overall structural integrity and manufacturing simplicity of the cellular design
2Object-affected harmful factors
If light absorbing material is added at cellular unit interfaces to block light leakage, then light blocking performance is improved, but device complexity increases
Solution Approach 1:
The light-absorbing material is integrated with existing cellular components such as the head rail, bottom rail, or cellular unit structures. By merging the light-blocking function with existing structural elements, the patent avoids adding completely separate components, thereby reducing the increase in device complexity while still achieving effective light leakage prevention
3Strength
If cellular units are connected with visible adhesive lines for structural integrity, then strength and reliability are improved, but insulative qualities deteriorate due to thermal conduction through connections
Solution Approach 1:
The patent employs composite material strategies by combining different materials with complementary properties. The light-absorbing material used to block light often also provides thermal insulation properties, creating a multi-functional element that simultaneously addresses light leakage and thermal conduction issues while maintaining structural integrity
