Innovation Solution

Incorporating a microcontroller into the ophthalmic lens, which can be powered by an energy source and embedded within the lens, allowing for programmable control of components to dynamically adjust optical characteristics, such as focal powers and other functionalities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a microcontroller is embedded within the ophthalmic lens to enable dynamic adjustment of optical characteristics, then the adaptability and functionality of the lens is improved, but the device complexity and manufacturing difficulty increases

Engineering Contradiction:
Improvedynamic adjustment of optical characteristicsVSAvoidembedded microcontroller system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the microcontroller, energy source, and optical components into a single integrated contact lens system. The microcontroller is embedded directly within the lens structure, merging previously separate components (control unit, power source, optical elements) into one unified device that can dynamically adjust optical characteristics while maintaining wearability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The contact lens is designed to perform multiple functions: optical correction, dynamic focal power adjustment, and potential additional functionalities controlled by the embedded microcontroller. This multi-functional design allows a single device to replace multiple separate optical aids, improving adaptability across different visual needs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a microcontroller and energy source are embedded within the ophthalmic lens, then the functionality and adaptability is improved, but the volume and weight of the lens increases

Engineering Contradiction:
Improveprogrammable control of componentsVSAvoidlens volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent places the microcontroller and energy source in specific localized regions within the contact lens structure, rather than uniformly distributing components throughout. This strategic positioning minimizes the overall volume occupied by electronic components while ensuring proper functionality and comfort fit on the eye.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The microcontroller and energy source are nested within the contact lens structure, with components arranged in a compact, space-efficient configuration. The smaller electronic components are integrated into the lens matrix or positioned in dedicated cavities, allowing the lens to maintain a thin, wearable profile despite containing multiple functional elements.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of manufacture

If conventional casting or lathing methods are used to form the lens, then the manufacturing process is simple, but the optical qualities remain static and cannot be changed

Engineering Contradiction:
Improvecasting or lathing processVSAvoidstatic optical qualities
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent transitions from static optical qualities fixed during manufacturing to dynamic optical characteristics that can be adjusted in real-time. The embedded microcontroller enables the lens to change focal powers and optical properties during wear, allowing the lens to adapt to different visual tasks and conditions rather than being limited to a single predetermined optical design.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The optical parameters of the lens (such as focal power, curvature, or refractive index) are made variable through electronic control. The microcontroller can modify these parameters dynamically based on user needs, environmental conditions, or detected visual requirements, transforming the lens from a fixed optical element to an adaptive optical system.

Inventive Principle:
Principle #35Parameter changes
