Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swimming goggles, particularly the separate type with a rigid connecting member, fail to accommodate various nose profiles, leading to discomfort and water leakage due to lack of flexibility.
Innovation Solution
The design incorporates a hard combined frame with soft, bendable components, including a connecting member and frames made of Thermoplastic Rubber, and hard buckles for ergonomic fit and water prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid connecting member is used to connect the left and right frames, then the structural strength is improved, but the adaptability to different nose profiles deteriorates
Solution Approach 1:
The connecting member is divided into multiple segments that can rotate relative to each other, allowing the structure to bend and adapt to different nose profiles while maintaining overall structural integrity through the segmented joint mechanism
Solution Approach 2:
The connecting member transitions from a static rigid structure to a dynamic multi-segment structure with rotational joints, enabling it to change shape and adapt to various user face geometries while preserving strength through controlled mechanical movement
2Manufacturing precision
If a rigid connecting member is used, then the manufacturing precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The connecting member is segmented into multiple rigid sections connected by rotational joints, allowing each segment to be manufactured with high precision while the assembly as a whole provides flexible adjustment for easy fitting to different users
Solution Approach 2:
The static precision-manufactured rigid structure is transformed into a dynamic multi-segment mechanism that maintains manufacturing precision in each component while enabling easy adjustment and fitting through rotational movement
3Stability of the object's composition
If the left and right frames are not flexible, then the structural stability is improved, but the reliability deteriorates due to water leakage
Solution Approach 1:
The frame structure is segmented with flexible joints that allow controlled deformation to maintain seal contact with the user's face, preventing water leakage while preserving overall structural stability through the segmented design
Solution Approach 2:
The static rigid frame is transformed into a dynamic structure with flexible joints that can adapt to different face shapes, ensuring reliable water leakage prevention through maintained seal contact while keeping structural stability intact

Function Achieved in This Case
The solution allows for a comfortable, leak-proof fit for users with different nose and face profiles by providing flexibility at the nose bridge and temple areas, ensuring the goggles fit snugly without water ingress.
Implementation Method 1
The connecting member has first means with bendable flexibility for fitting to users' nose profiles
Implementation Method 2
The first assembling frame and the second assembling frame have second means with bendable flexibility for fitting to users' face profiles
