Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional display system uses LED light sets and backlight panels to illuminate patterns, then functional identification is achieved, but the display lacks aesthetic appeal and three-dimensional display capabilities in standby mode
Solution Approach 1:
The display system is segmented into multiple independent layers: a background display layer with light guide plate and background light source, and a functional display layer with functional film containing gratings and functional light sources. This segmentation allows each layer to independently contribute to the overall display effect, enabling both functional identification and aesthetic background display simultaneously.
Solution Approach 2:
The patent introduces a vertical stacking dimension by placing the background display layer and functional display layer at different depths within the housing. The background light guide plate is positioned behind the functional film, creating a three-dimensional layered structure that provides depth and aesthetic appeal while maintaining functional clarity.
2Loss of information
If patterned edge-illuminated LED displays directly display patterns and digital lamp tubes in standby state, then information is visible, but the front panel appears nonsolid and disjointed
Solution Approach 1:
A transparent or semi-transparent surface film is introduced as an intermediary layer between the background light guide plate and the functional film. This surface film can display background patterns when illuminated, creating a solid and continuous front panel appearance while still allowing light to pass through to the functional display layer below.
3Ease of operation
If functional light sources are positioned to correspond with light-transmitting grooves in the partition plate, then precise light control is achieved, but the device structure becomes more complex
Solution Approach 1:
The partition plate is pre-formed with light-transmitting grooves at specific positions during manufacturing. These grooves are designed in advance to align with the functional light sources on the PCB, ensuring precise light control without requiring complex adjustment mechanisms or post-assembly alignment procedures.
