Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional optical lens assemblies are used to achieve image magnification and shooting functions, then the imaging capability is maintained, but the device thickness increases significantly
Solution Approach 1:
The patent uses a light-transmitting film with microlens assemblies that optically copies and processes light to create magnified images, replacing the need for thick traditional optical lens assemblies. The microlens array creates multiple virtual images that are then processed to achieve the desired magnification effect without requiring substantial physical thickness.
Solution Approach 2:
The patent changes the optical parameters by using a light-transmitting film with specific microlens configurations (different focal lengths, diameters, and distribution patterns) to achieve variable magnification effects. This allows image magnification to be controlled through optical parameter variations rather than physical lens thickness.
2Ease of operation
If multiple optical lenses are assembled to achieve imaging functions, then the image quality is maintained, but the device volume increases
Solution Approach 1:
The patent merges multiple optical functions (light transmission, focusing, magnification) into a single integrated light-transmitting film structure containing microlens assemblies. This consolidation achieves the same imaging and magnification functions that traditionally required multiple separate optical lenses, thereby reducing overall device volume.
Solution Approach 2:
The patent transitions from traditional three-dimensional optical lens assemblies to a two-dimensional light-transmitting film with microlens patterns. This dimensional reduction allows multiple optical functions to be achieved in a planar structure, significantly reducing the volume required for imaging components.
3Length of stationary object
If a light-transmitting film with microlens assemblies is used to thin the device, then the device thickness is reduced, but the ability to generate images with different magnifications is limited
Solution Approach 1:
The patent segments the light-transmitting film into multiple regions, each containing microlens assemblies with different optical parameters (focal lengths, diameters, distribution patterns). This segmentation allows different portions of the film to generate images with different magnifications, providing versatility while maintaining thin device profile.
Solution Approach 2:
The patent applies local quality by assigning different microlens configurations to different regions of the light-transmitting film. Each region has optimized local optical properties (different focal lengths, diameters, or patterns) to produce specific magnification effects, enabling the device to generate multiple magnification levels from a single thin film structure.
