Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If existing anti-blue light protective films are used, then blue light protection is provided to some extent, but other protective functions such as anti-glare are not provided
Solution Approach 1:
The patent applies multi-functionality by integrating multiple protective functions into a single display apparatus structure. Specifically, the touch sensing layer and functional layers are configured with both anti-blue light structures and anti-glare structures, enabling the display to simultaneously provide blue light protection and glare reduction without requiring separate films or layers for each function.
Solution Approach 2:
The patent combines anti-blue light structures and anti-glare structures within the same functional layers. The touch sensing layer and functional layers are designed to incorporate both types of protective structures, merging previously separate protection mechanisms into a unified structure that delivers comprehensive eye protection and visual comfort.
2Adaptability or versatility
If multiple protective layers are added to provide both anti-blue light and anti-glare functions, then comprehensive protection is achieved, but device complexity increases
Solution Approach 1:
The patent reduces structural complexity by merging anti-blue light structures and anti-glare structures into the existing touch sensing layer and functional layers. Rather than adding separate protective films or layers, the invention integrates both protective functions within the current layer structure, achieving comprehensive protection without increasing the number of discrete components.
Solution Approach 2:
The existing functional layers are designed to serve multiple purposes: they maintain their primary functions while simultaneously incorporating anti-blue light and anti-glare capabilities. This multi-functionality approach allows the display apparatus to achieve comprehensive protection using the same structural framework, avoiding the need for additional specialized layers.
