Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ophthalmic lenses are static and lack the ability to change characteristics in a controlled manner, necessitating a means to energize and activate functions on demand, such as energy savings and user-activated states.
Innovation Solution
Incorporating detection components like photodiodes, photoresistors, and Hall Effect sensors to detect external signals for controlling power within the lens, allowing for activation or deactivation of components, and enabling wireless energy recharging and state changes based on photon, magnetic, pressure, or sound signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ophthalmic lenses are made static, then manufacturing is simple and reliable, but functionality and adaptability are limited
Solution Approach 1:
The patent applies the dynamics principle by transforming the static lens into a dynamic system with controllable functions. The lens incorporates an energy source and detection components that enable it to change its operational state based on external signals, allowing functions like focal adjustment and chemical dispensing to be activated or deactivated on demand, thus resolving the contradiction between simplicity and functionality.
Solution Approach 2:
The patent applies segmentation by dividing the lens system into distinct functional modules: detection components (photodiodes, Hall Effect sensors), energy source, control circuitry, and functional elements (focal adjustment mechanism, chemical dispensing system). This modular approach enables independent control of each function while maintaining overall system manageability, addressing the complexity-functionality tradeoff.
2Ease of operation
If detection components are added to enable signal detection, then activation control is improved, but device complexity increases
Solution Approach 1:
The patent replaces mechanical activation mechanisms with non-contact detection systems. Instead of requiring physical buttons or switches, the lens uses photodiodes to detect light signals, Hall Effect sensors to detect magnetic fields, and other non-mechanical sensors to receive activation commands wirelessly. This substitution maintains ease of operation while reducing mechanical complexity and wear.
Solution Approach 2:
The patent implements multi-functionality by incorporating detection components that can respond to multiple types of external signals (light, magnetic fields, pressure, sound) through a unified control architecture. This universal approach allows a single detection system to handle various activation methods, improving ease of operation without proportionally increasing complexity.
3Adaptability or versatility
If energy source is incorporated into the lens, then functional capability is improved, but weight and volume increase
Solution Approach 1:
The patent applies periodic action by implementing an energy source that operates intermittently rather than continuously. The lens enters low-power states when not in use and activates energy-consuming functions only when external signals trigger specific operations (focal adjustment, chemical dispensing). This periodic operation模式 reduces average energy consumption and allows for smaller, lighter energy storage components compared to continuous operation systems.
