Solution Overview
Problem
Existing illuminable pane units face challenges in achieving homogeneous light distribution, transparency when switched off, and protection against dirt, dust, humidity, and surface scratching, with high power input leading to heat buildup and inefficient light coverage.
Innovation Solution
A pane unit with a frame structure that supports an illuminable pane and includes a receptacle for an electrically operated lighting element, allowing for a homogeneous light field, with optional features like lockable guidance for maintenance, curved designs, and adjustable lighting elements for varied brightness and color, using materials like metal, synthetic, or wood, and incorporating transparent or tintable panes for protection and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If switchable surface area light sources are used to illuminate the pane, then the pane can be illuminated, but the light distribution is not homogeneous and the transparency when switched off is insufficient
Solution Approach 1:
The patent divides the illumination function into separate linear lighting elements positioned at the edges of the pane rather than using a single surface area light source. This segmentation allows each linear element to contribute to homogeneous light distribution while maintaining pane transparency when switched off, as the linear elements can be designed to be transparent or invisible in the off state.
Solution Approach 2:
The patent introduces linear lighting elements as intermediary components between the power source and the pane surface. These linear elements serve as mediators that convert electrical energy to light in a controlled manner along the pane edges, achieving homogeneous illumination without requiring opaque surface area sources that would compromise transparency when off.
2Area of stationary object
If surface area light sources are used to cover the entire area, then the light coverage is improved, but undesired reflections occur and the maximum area and luminance are limited
Solution Approach 1:
The patent extracts the light source from the pane surface and relocates it to linear elements positioned at the edges. This extraction eliminates the harmful reflections that occur when light sources are directly on the pane surface, while still achieving comprehensive light coverage across the entire pane area through the distributed linear elements.
3Illumination intensity
If switchable surface area light sources are used, then the pane can be illuminated, but the sources are not transparent in the switched-off state and the maximum area and luminance are limited
Solution Approach 1:
By segmenting the illumination system into multiple linear elements at the edges rather than a single surface source, the patent achieves high luminance through cumulative light output while maintaining transparency when off. Each linear element can be designed to be transparent in the off state, and their distributed positioning allows comprehensive illumination coverage without compromising transparency.
4Illumination intensity
If surface area light sources are used, then the pane can be illuminated, but the sources are deficient in protection against dirt, dust, humidity, and surface scratching
Solution Approach 1:
The patent extracts the light sources from the vulnerable pane surface and relocates them to protected linear elements positioned in the frame structure or at the edges. This extraction provides natural protection against dirt, dust, humidity, and scratching, as the linear elements are positioned in more protected locations while still delivering the required light output through their distributed arrangement.
5Illumination intensity
If high power input is used to illuminate the pane, then the luminance is improved, but heat buildup increases and requires high input for dissipation
Solution Approach 1:
By segmenting the illumination into multiple linear elements distributed at the pane edges, the patent distributes the heat generation across multiple locations rather than concentrating it in a single surface source. This segmentation facilitates more efficient heat dissipation to the surrounding environment through the frame structure and edge positions, while still achieving the required luminance through cumulative light output from all linear elements.
