Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety glasses are uncomfortable to wear due to their hard plastic lenses, which cause pain and do not meet market demands for both protection and aesthetic appeal.
Innovation Solution
A glasses structure featuring a main body with a reverse V-shaped notch and nose pads, combined with a sub-frame that includes colored or patterned components, providing three-point positioning for stability and reducing contact pressure with the nose and forehead, while allowing for customizable style.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safety glasses are tightly contacted with the worker's face to prevent foreign objects from injuring the eye, then protection function is improved, but wearing comfort deteriorates due to pain caused by hard lens material
Solution Approach 1:
A sub-frame with pad is introduced as an intermediary component between the hard lens and the wearer's face. The pad acts as a soft mediator that distributes contact pressure across the forehead and nose, reducing pain while maintaining the protective function of the hard lens.
Solution Approach 2:
The glasses are divided into two functional segments: the main body with hard lens for protection, and the sub-frame with soft pad for comfort. This segmentation allows each component to fulfill its specific function without compromising the other.
2Reliability
If safety glasses are made with hard plastic lens material for effective protection, then protection function is improved, but wearing comfort deteriorates due to pain
Solution Approach 1:
The glasses system is segmented into a hard lens component for protection and a soft pad component for comfort. The hard lens maintains its protective function while the soft pad absorbs the discomfort of facial contact.
Solution Approach 2:
The soft pad serves as an intermediary layer between the hard lens and the wearer's face, transferring the protective function to the lens while the pad handles the comfort function by distributing pressure.
3Reliability
If safety glasses focus only on protection function from foreign objects, then protection function is improved, but aesthetic appeal and market adaptability deteriorate
Solution Approach 1:
The sub-frame serves multiple functions: it provides structural support, distributes pressure for comfort, and offers aesthetic customization through various colors and patterns. This multi-functionality allows the glasses to meet both protective and aesthetic demands.
Solution Approach 2:
The sub-frame is available in various colors and patterns, allowing users to customize the aesthetic appearance to match their style and clothing, thereby enhancing adaptability without compromising protection.

AI summary
A glasses structure comprises a main body and a sub-frame assembled at the rear of a lens of the main body. The inner surface of a frame body of the sub-frame is attached with a pad, which pad is formed with an upper contact portion and a central contact portion corresponding to the upper edge and the central shape of the frame body. Two nose pieces are formed at the both sides of the central contact portion of the pad, and the upper contact portion of the pad are respectively contacted with the user's nose and forehead to avoid pain when the user wears the glasses. Furthermore, the colored and patterned frame body of the sub-frame is shown from the transparent lens of the main body, whereby the glasses with suitable color and pattern being chosen to dress with the user's clothes and style, increasing the user's fashion and beauty.
