Dimming Glass Window Control Unit Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dimming vehicle windows face issues during installation and maintenance where the FPCs connecting the function layers to the control module are prone to damage due to their external location.
Innovation Solution
The dimming glass window design places the touch function layer and dimming function layer between the inner and outer glass assemblies, with the control unit located in the accommodation space between them, ensuring the FPCs are protected from external damage, and uses reticulated adhesive layers for bonding to enhance stability and prevent bubble issues during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control unit is located outside the glass unit, then the installation and maintenance is easier, but the FPCs are prone to damage during installation and maintenance
Solution Approach 1:
The control unit is nested within the accommodation space between the inner and outer glass assemblies, placing the control electronics inside the protected glass sandwich structure rather than outside, thereby protecting FPCs from external damage while maintaining accessibility for maintenance through the front surface
2Reliability
If the touch function layer and dimming function layer are arranged between glass assemblies, then the FPCs are protected from external damage, but the assembly complexity increases
Solution Approach 1:
The glass window is segmented into distinct assemblies (inner glass assembly with touch layer, outer glass assembly with dimming layer) that can be manufactured and tested separately, then assembled together with the control unit in between, reducing overall complexity while providing protection
3Stability of the object's composition
If reticulated adhesive layers are used for bonding, then the stability of touch function layer is improved and bubble issues are prevented, but the manufacturing process becomes more complex
Solution Approach 1:
Reticulated adhesive layers with porous structures are used between glass plates and function layers, allowing air bubbles to escape during assembly while providing strong bonding, thus improving stability and preventing bubble defects despite added manufacturing steps
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
This configuration prevents FPC damage during installation and maintenance, improves the stability of the touch function layer, and allows for effective light transmittance adjustment through gesture control, providing a durable and functional dimming solution for vehicle windows.
Implementation Method 1
a reticulated adhesive layer is arranged between the first glass plate and the touch function layer, and the first glass plate is bonded to the touch function layer through the reticulated adhesive layer
Implementation Method 2
a touch function layer and a dimming function layer, wherein both of the touch function layer and the diming function layer are arranged between the inner glass assembly and the outer glass assembly

AI summary
A dimming glass window and a vehicle. The dimming glass window includes: a glass unit including an inner glass assembly and an outer glass assembly which are oppositely arranged, an accommodation space is between the inner glass assembly and the outer glass assembly; a touch function layer and a dimming function layer arranged between the inner glass assembly and the outer glass assembly, the touch function layer is on an inner side of the dimming function layer; a control unit in the accommodating space and connected to the touch function layer and the dimming function layer; and a dimming controller arranged outside the glass unit, the dimming controller is connected to the control unit by a wire so as to match the control unit, the touch function layer and the dimming function layer to implement light transmittance adjustment of the dimming glass window. The vehicle includes the dimming glass window.
