Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyewear frames are often poorly fitted, leading to discomfort and inadequate protection, as they cannot be easily adjusted to accommodate different head morphologies or activities, and existing solutions to improve fit often add weight or are cumbersome.
Innovation Solution
Incorporating stimuli-responsive polymers that change physical properties in response to non-thermal stimuli, allowing for reversible adjustments in shape, texture, and grip, enabling customizable fit and protection without adding weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed-position frame components are used, then manufacturing simplicity is maintained, but adaptability to different wearers and activities is poor
Solution Approach 1:
The patent applies the dynamics principle by making the frame component physically changeable through stimuli-responsive polymers that reversibly alter their physical properties in response to non-thermal stimuli. This allows the frame to transition between different states (e.g., adjustable and fixed positions) without requiring complex mechanical adjustment mechanisms, thereby improving adaptability while maintaining relatively simple structure.
Solution Approach 2:
The patent employs parameter changes by utilizing materials whose physical properties (such as shape, rigidity, or size) can be reversibly modified through external stimuli like light, electric fields, or magnetic fields. This enables the frame component to adapt to different wearers and activities by changing its physical parameters without adding mechanical complexity.
2Reliability
If additional components are added to increase grip, then fit improvement is achieved, but weight increases
Solution Approach 1:
The patent uses stimuli-responsive polymers that can reversibly change their physical properties (such as surface texture, rigidity, or shape) in response to non-thermal stimuli. This allows the frame to dynamically adjust its grip characteristics without adding extra components, thereby improving grip reliability while avoiding additional weight.
3Adaptability or versatility
If frame components are made adjustable, then adaptability improves, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical adjustment mechanisms with stimuli-responsive polymers that change their physical properties in response to non-thermal stimuli such as light, electric fields, or magnetic fields. This substitution eliminates complex mechanical parts while providing adjustable functionality, thereby improving adaptability without significantly increasing device complexity.
Solution Approach 2:
The patent applies dynamics by enabling the frame component to transition between different physical states through external stimuli. This dynamic behavior allows the frame to be adjustable without requiring mechanical adjustment mechanisms, as the material itself can change its properties reversibly in response to applied stimuli.
