Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electroactive devices, such as Insulated Glazing Units (IGUs), face installation challenges due to the visibility of internal components like busbars, which can compromise security, aesthetics, and light sensitivity.
Innovation Solution
Implementing electrically conductive adhesive tape busbars with opaque covers that satisfy visibility requirements, allowing for flexible installation and secure, aesthetic concealment while maintaining electrical conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If busbars are made visible for installation purposes, then installation ease is improved, but security and aesthetics deteriorate
Solution Approach 1:
The busbar is divided into two functional segments: a conductive portion for electrical connection and an opaque cover portion for security and aesthetics. The cover is applied over the conductive portion, allowing the conductive part to remain exposed for installation while the covered part provides security when visible
Solution Approach 2:
Different portions of the busbar have different properties: the conductive portion is exposed for electrical connectivity, while specific visible portions are covered with opaque material to provide security and aesthetic benefits where needed
2Object-affected harmful factors
If busbars are covered with opaque material, then security and aesthetics are improved, but electrical conductivity deteriorates
Solution Approach 1:
The busbar structure separates the conductive function from the covering function, with the opaque cover applied only over portions that need security/aesthetic protection while leaving conductive portions exposed or ensuring conductivity through the cover structure
Solution Approach 2:
The adhesive tape serves as an intermediary material that provides both mechanical attachment and electrical conductivity, allowing the opaque cover to be secured to the busbar while maintaining electrical connection through the adhesive layer
3Ease of operation
If adhesive tape is used to attach covers, then ease of installation is improved, but manufacturing precision deteriorates
Solution Approach 1:
The adhesive tape parameters (adhesive strength, tape width, thickness) are selected to provide both ease of installation and sufficient precision for proper alignment and secure attachment of the opaque cover to the busbar
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 effectively obscures busbars from external view, addressing security and aesthetic concerns while ensuring reliable power and signal transmission to electroactive devices.
Implementation Method 1
The busbars may be an electrically conductive adhesive tape, that includes an electrically conductive adhesion layer
Implementation Method 2
The cover may be electrically conductive in at least one direction, the one direction being toward the conductor track of the busbar

AI summary
Busbars with electrically conductive covers are implemented for an electroactive device. Different transparent conductive layers may surround an electroactive layer that is between the transparent conductive layers of the electroactive devices. The busbars may include an electrically conductive adhesive tape that includes an adhesion layer, a conductor track, and cover that is electrically conductive toward the conductor track, capable of being soldered or adhered to a conductor, opaque, and satisfy a visibility requirement that obscures the busbar from an environment external to the electroactive device and that is connective using the adhesive layer to one of the transparent conductive layers.
