Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If icons or logos are printed on electronic devices using traditional methods (screen printing, inkjet printing, lithography), then the icons or logos can be formed on the device surface, but the icons or logos cannot be rendered invisible or changed in color in real time
Solution Approach 1:
The patent applies the dynamics principle by transitioning from static printed icons to dynamic controllable icons. The light-shielding layer with openings allows light to pass through and be reflected back, enabling the icon to dynamically change between visible and invisible states based on light control, rather than being fixed like traditional printed icons.
Solution Approach 2:
The patent applies the color changes principle by enabling the icon to change its visual appearance through light control. By controlling the light that passes through the openings in the light-shielding layer, the icon can transition between different visual states (visible/invisible, different colors) without physical repainting, achieving real-time color change capability.
2Adaptability or versatility
If a light-shielding layer with openings is used to make icons invisible, then the icon can be rendered invisible or changed in color in real time, but the structure becomes more complex
Solution Approach 1:
The patent applies the universality principle by designing the light-shielding layer with openings to serve multiple functions: it acts as both a light-shielding structure and a light-transmitting structure. The same layer that blocks light in certain areas allows light to pass through the openings, enabling both icon visibility control and color change functions without requiring separate components.
Solution Approach 2:
The patent applies the intermediary principle by introducing the light-shielding layer with openings as an intermediary between the icon and the external environment. This intermediate structure controls the light interaction with the icon, enabling the icon to be rendered invisible or change color by mediating light transmission rather than requiring direct modification of the icon itself.
3Ease of manufacture
If traditional printing methods are used, then the manufacturing process is simple, but the icons cannot be made invisible when not in use
Solution Approach 1:
The patent applies the segmentation principle by dividing the light-shielding layer into regions with different properties: areas that shield light and areas with openings that transmit light. This segmentation allows different parts of the icon to have different visibility characteristics, enabling selective visibility control while maintaining manufacturing simplicity through standard lithography processes.
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 allows icons or logos to be made invisible when not in use and enables real-time color adjustments, enhancing the device's appearance and reducing manufacturing costs.
Implementation Method 1
a light-shielding layer having an icon area, and the openings in the icon area has an aperture ratio in a specific range, so that the icon or logo on the electronic device can be rendered invisible or backgrounded as required

AI summary
An electronic device is provided. The electronic device includes a substrate and a light-shielding layer. The light-shielding layer is disposed on the substrate. The light-shielding layer has an aperture region. The light-shielding layer has a plurality of openings in the aperture region and at least two of the plurality of openings have different areas. The plurality of openings have an aperture ratio in the aperture region, and the aperture ratio is greater than 0% and less than or equal to 20%. Moreover, the aperture ratio is as shown in the following formula: the aperture ratio (%)=a total area of the plurality of openings/(the total area of the plurality of openings+a total area of the light-shielding layer)×100%.
