Innovation Solution
A smart contact lens design featuring a light-transmitting body with multiple view windows and transmission paths, integrating control, image-sensing, image display, wireless transmission, bio-sensing, and power supply modules, allowing external images to be projected onto the eyeball while capturing and processing images through image-sensing chips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If contact lenses integrate image-capturing and display modules, then functionality and user experience are enhanced, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent embeds multiple functional modules (image-sensing module, image display module, control module, power supply module) within the limited space of the contact lens structure. The light-transmitting body contains cavities that house these modules in a nested arrangement, allowing the lens to perform multiple functions (image capture, display, wireless communication, power management) while maintaining a compact form factor suitable for contact lens application.
2Measurement precision
If multiple view windows and transmission paths are designed, then image transmission and sensing capabilities are improved, but manufacturing precision requirements increase
Solution Approach 1:
The light-transmitting body is divided into multiple light-transmitting portions (first, second, third, fourth portions) with distinct functions. The first light-transmitting portion transmits external images to the eyeball, while the second light-transmitting portion directs images to the image-sensing module. This segmentation allows each portion to be optimized for its specific function and simplifies the manufacturing process by breaking down the complex optical system into manageable components with clear functional boundaries.
3Measurement precision
If image-sensing chips are positioned at a predetermined horizontal distance from the second view window, then image capture quality is improved, but the available space within the contact lens is reduced
Solution Approach 1:
The patent utilizes the third dimension (depth) within the contact lens structure to position the image-sensing module. By placing the image-sensing chips at a predetermined horizontal distance from the second view window and embedding them within cavities in the light-transmitting body, the design effectively uses vertical space to achieve the required horizontal separation. This dimensional approach allows sufficient distance for quality image capture while maintaining a compact overall lens structure.
4Adaptability or versatility
If control, image-sensing, image display, wireless transmission, bio-sensing, and power supply modules are integrated, then versatility is enhanced, but ease of manufacture decreases
Solution Approach 1:
The contact lens is designed as a multi-functional integrated system where a single device performs multiple functions: the image-sensing module captures images, the image display module displays images on the eyeball, the control module coordinates operations, the power supply module provides energy, and wireless transmission enables data communication. This universal design allows one contact lens to replace multiple separate devices, enhancing versatility while the modular architecture facilitates standardized manufacturing processes for each functional module.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the capture and display of external images, providing enhanced functionality and user experience while maintaining the comfort and aesthetic appeal of traditional contact lenses.
Implementation Method 1
The light-transmitting body has a first view window and a second view window surrounding the first view window. An external light source that has been received by the first view window can directly pass through the light-transmitting body and then be projected onto an eyeball. The external light source that has been received by the second view window can be transmitted to the image-sensing chips through the transmission path.

AI summary
The present disclosure provides a smart contact lens for capturing images and a light-transmitting body thereof. The smart contact lens includes a light-transmitting body, an image-sensing module and an image display module. The light-transmitting body has a first view window and a second view window. The image-sensing module diverges from the second view window. The image display module diverges from the first view window. The light-transmitting body has a first transmission path formed between the second view window and the image-sensing module. An external image source that has been received by the second view window is transmitted to the image-sensing module through the first transmission path.
