Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laminated glass systems require cables for power supply and signal transmission to the light control film, which is inefficient and prone to deterioration due to repeated opening and closing of movable windows.
Innovation Solution
A laminated glass system utilizing wireless power supply and wireless apparatus, incorporating a sheet-shaped functional element, power receiving portion, driving portion, and control portion within an interlayer film, eliminating the need for cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are used to connect the light control film and vehicle main body for power supply and signal transmission, then the light control function can be achieved, but the attachment process becomes complex and the cable deteriorates over time due to repeated opening and closing of movable windows
Solution Approach 1:
The patent extracts and eliminates the cable component from the system by implementing wireless power supply and wireless communication. The light control film is powered through wireless energy transmission and receives control signals via wireless communication, completely removing the physical cable connection that caused deterioration and attachment complexity.
Solution Approach 2:
The patent replaces the mechanical cable connection system with wireless transmission systems. Power is transmitted wirelessly through electromagnetic fields, and control signals are communicated wirelessly, substituting the mechanical cable-based system with non-contact electromagnetic transmission.
2Use of energy by moving object
If cables are connected to the laminated glass for power supply, then the light control film can be powered, but the attachment process becomes inefficient and complex
Solution Approach 1:
The patent removes the cable component from the power supply system by implementing wireless power transmission. The light control film receives power through wireless energy transfer, eliminating the need for physical cable connections during attachment and operation.
Solution Approach 2:
The patent replaces the mechanical cable connection for power supply with wireless electromagnetic power transmission. This substitution eliminates the attachment complexity associated with cable connections while maintaining the power supply capability to the light control film.
