Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If composite materials are made up of distinct components, then the materials can be tailored for specific applications, but they lack the ability to dynamically change visual outputs in response to stimuli
Solution Approach 1:
The patent incorporates optical change components that can dynamically alter their visual properties (transparency, color, brightness) in response to stimuli such as heat, light, or electricity. This transforms the static composite material into a dynamic system that can adapt its appearance based on environmental conditions or applied energy, directly resolving the contradiction between adaptability and compositional stability.
Solution Approach 2:
The invention utilizes components that change their optical parameters (refractive index, absorption coefficients, transmission properties) when exposed to different stimuli. By controlling these parameter changes, the composite material can switch between different visual states while maintaining its underlying structural integrity, thus achieving dynamic visual output without compromising material stability.
2Adaptability or versatility
If flash imaging devices use optical change components that undergo changes in response to stimuli, then reversible or irreversible image display is enabled, but the device complexity increases
Solution Approach 1:
The patent merges the optical change component directly with the substrate to form an integrated composite material structure. This consolidation reduces the number of separate parts and simplifies the overall device architecture while still enabling reversible or irreversible image display functionality, thus resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The optical change component serves multiple functions simultaneously: it acts as both the imaging medium and the response element to stimuli. This multi-functionality reduces the need for additional separate components, thereby reducing device complexity while maintaining the capability for reversible or irreversible image display.
3Ease of manufacture
If the optical change component is integrated with the substrate, then the manufacturing process is simplified, but the manufacturing precision requirements increase
Solution Approach 1:
The patent employs composite material techniques to integrate the optical change component with the substrate, creating a unified structure that can be manufactured as a single piece or pre-assembled unit. This approach simplifies the manufacturing process by eliminating the need for complex assembly operations, while the composite material structure itself provides the necessary precision through its inherent structural integrity and controlled composition.
