Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a traditional display interaction system with LED light sets and button modules is used, then functional identification is achieved, but the display shows visible contours and patterns in standby mode, lacking aesthetic appearance
Solution Approach 1:
The display is segmented into multiple functional layers: a light guide plate for background illumination, a functional film with patterns for operational display, and a surface film for user interaction. This segmentation allows different layers to serve different purposes - the light guide plate provides aesthetic background lighting while the functional film provides operational information, resolving the contradiction between visibility and appearance.
Solution Approach 2:
The patent transitions from traditional two-dimensional flat display to a three-dimensional multi-layered structure with the light guide plate, functional film, and surface film stacked vertically. This dimensional change enables background illumination to pass through multiple layers, creating depth and aesthetic appearance while maintaining functional visibility.
2Loss of information
If patterned edge-illuminated LED displays are used, then functional patterns can be displayed, but the front panel appears nonsolid and disjointed in standby state
Solution Approach 1:
The light guide plate acts as an intermediary between the background light source and the functional film. It distributes light uniformly across the display area, creating a solid, uniform background that masks the disjointed appearance of individual LED elements while still allowing functional patterns to be clearly displayed through the functional film.
3Shape
If multiple display layers are added to achieve background display and three-dimensional effect, then aesthetic appearance is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated display assembly. The light guide plate, functional film with patterns, and surface film are combined into one unit that simultaneously provides background illumination, functional information display, touch interaction, and aesthetic appearance. This merging reduces overall system complexity compared to having separate components for each function.
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 device achieves a dynamic background display in standby mode, concealing internal structures and providing a three-dimensional functional pattern display in startup mode, enhancing aesthetics and user experience with controlled lighting effects.
Implementation Method 1
the background light source provides unilateral/multilateral lateral illumination to the light guide plate
Implementation Method 2
the functional light source of the PCB is activated, illuminates the functional film, and provides a three-dimensional display function through the plurality of gratings
