Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple ink layers are added to express various designs, then design versatility is improved, but device complexity increases
Solution Approach 1:
The light transmission rate adjustment layer has different light transmission rates in different regions (high-transmission regions and low-transmission regions), allowing different parts of the same layer to serve different functions. This enables watermark patterns and regular patterns to be expressed within a single layer structure, achieving design versatility without adding multiple ink layers.
Solution Approach 2:
The invention changes the light transmission rate parameter of the ink layer to create different visual effects. By adjusting the light transmission rate to be either high or low in different regions, the same ink layer can express both watermark patterns and regular patterns, eliminating the need for additional ink layers and reducing overall structure complexity.
2Adaptability or versatility
If a light transmission rate adjustment layer is added to achieve watermark effects, then design expression capability is improved, but device complexity increases
Solution Approach 1:
The invention merges the functions of watermark pattern expression and regular pattern expression into a single light transmission rate adjustment layer. By combining high-transmission and low-transmission regions within one layer, both watermark effects and regular patterns can be achieved simultaneously, avoiding the need for separate ink layers and reducing device complexity.
Solution Approach 2:
The light transmission rate adjustment layer serves multiple functions: it acts as both a watermark pattern layer (through high-transmission regions) and a regular pattern layer (through low-transmission regions). This multi-functionality allows a single layer to replace what would traditionally require multiple separate layers, thereby improving design expression capability while maintaining simple device structure.
Applied Scientific Principles

Function Achieved in This Case
Enables the expression of various designs without excessively adding ink layers, utilizing translucent media and reflective inks to create watermark-pattern-like effects, enhancing design versatility.
Implementation Method 1
the light transmission rate adjustment layer causes light to be transmitted through the printed matter such that a pattern corresponding to a shape of the high-transmission region is visually recognized by an observer observing the image layer from the observation-surface side, when irradiated with rear-surface light

AI summary
Various designs are appropriately expressed by a printed matter. A printed matter 52 in which a plurality of ink layers overlap each other includes an image layer 202 and a transmission rate control layer 204, and as the transmission rate control layer 204 has a low-transmission region 302 and a high-transmission region 306, light is transmitted through the printed matter 52 such that a pattern corresponding to a shape of the high-transmission region 306 is visually recognized from an observation-surface side when irradiated with rear-surface light, and the pattern corresponding to the shape of the high-transmission region 306 becomes inconspicuous when not irradiated with the rear-surface light, for an observer observing the image layer 202 from the observation-surface side.
