Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional eyeglass nose pad arms are immobile and made of inflexible materials, limiting their adjustability and often leading to damage during manual adjustments, which compromises the fit and comfort of eyeglasses.
Innovation Solution
Intelligent actuated nose pad arms controlled by an actuator system, utilizing pneumatic actuators connected to a compressed air tank, adjusted by a machine learning model to optimize positioning based on user data and image analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If nose pad arms are made of inflexible materials to maintain structural strength, then strength is improved, but adaptability deteriorates because they cannot be adjusted
Solution Approach 1:
The patent applies the dynamics principle by transforming the static, inflexible nose pad arms into dynamic, adjustable components. The system uses actuators (pneumatic or electric) to enable the nose pad arms to change their position and orientation in three-dimensional space, allowing them to adapt to different user needs while maintaining structural integrity through controlled movement rather than material flexibility
2Device complexity
If nose pad arms are made immobile to simplify structure, then device complexity is reduced, but adaptability deteriorates as they cannot be adjusted for different users
Solution Approach 1:
The system implements self-service through automated actuation mechanisms that adjust the nose pad arms without requiring manual intervention. The actuator control system autonomously positions the nose pads based on user feedback or pre-programmed parameters, eliminating the need for complex manual adjustment mechanisms while maintaining high adaptability
3Adaptability or versatility
If manual adjustment of nose pad arms is performed to achieve custom fit, then adaptability is improved, but reliability deteriorates due to damage during adjustments
Solution Approach 1:
The patent replaces manual mechanical adjustment with automated actuation systems. Instead of relying on user hands to manipulate the nose pad arms (which causes damage), electric or pneumatic actuators perform the adjustment through controlled mechanical motion, significantly reducing the risk of damage while achieving precise custom fit
4Adaptability or versatility
If actuators are added to enable remote adjustment of nose pad arms, then adaptability is improved, but device complexity increases
Solution Approach 1:
The actuator control system is designed with multi-functionality to manage complexity. The same control architecture can accommodate different actuator types (pneumatic or electric), serve multiple nose pad arms simultaneously, and integrate with various user interfaces (manual controls, automated sensors, or wireless communication), making the system universally applicable while managing complexity through standardized design

AI summary
Systems and methods herein describe an actuator control system for controlling intelligent actuated nose pad arms of a pair of eyeglasses.
