Electronic Contact Lens Symmetry via Mirrored Component Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing electronic contact lenses with integrated circuits poses challenges due to the lack of left- and right-handed versions, requiring complex redesigns and manufacturing of separate layouts for each eye, increasing logistical costs and complexity.
Innovation Solution
Implementing a common layout for both left and right electronic contact lenses with components rotated by a specified angle (e.g., 180 degrees) relative to their respective axes, allowing for a single layout to be used for both, with functionally symmetric designs that maintain weight distribution and light obscuration symmetry across the vertical axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate layouts are designed for left and right electronic contact lenses, then the electronic components can be properly positioned for each eye, but the design complexity and manufacturing costs increase
Solution Approach 1:
The patent applies asymmetry by designing the electronic component layout to be mirrored between left and right lenses. Instead of creating completely separate layouts, the right lens layout is generated by mirroring the left lens layout across a vertical axis, maintaining proper positioning while reducing design complexity
Solution Approach 2:
The patent implements universality by creating a single base layout that can be adapted for both left and right lenses through mirroring. This universal layout design reduces manufacturing complexity while ensuring proper component positioning for each eye
2Reliability
If separate layouts are manufactured for left and right electronic contact lenses, then each lens can be optimized for its specific eye, but the manufacturing costs and logistical complexity increase
Solution Approach 1:
The manufacturing process utilizes asymmetry by producing mirror-image layouts for left and right lenses from a single master design. This approach maintains eye-specific optimization while significantly reducing manufacturing costs through template-based production
Solution Approach 2:
The patent applies copying by creating the right lens layout as a mirror copy of the left lens layout. This copying strategy eliminates the need for separate design and manufacturing processes for each lens type, reducing both costs and logistical complexity
3Adaptability or versatility
If electronic components are positioned without considering symmetry, then placement flexibility increases, but weight distribution and light obscuration become unbalanced
Solution Approach 1:
The patent resolves this contradiction by implementing mirror symmetry in the component layout. The mirrored arrangement provides structured placement flexibility while ensuring that weight distribution and light obscuration remain balanced between the two lenses when worn

AI summary
A pair of electronic contact lenses comprises a left electronic contact lens and a right electronic contact lens, to be worn on the left and right eyes of a user, respectively. Each electronic contact lens contains a respective electronic payload comprising a set of electronic components. Each of the electronic payloads contains an equivalent layout of electronic components, but are oriented a different rotation angles relative to a reference axis of the respective contact lens, where the reference axis refers to an axis of the contact lens that points in a predetermined direction when the contact lens is worn by the user and the user's head is in an upright position.
