Swimming Goggles with Segmented Frame Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming goggles lack the necessary rigidity and stability to maintain their position during use, especially in competitive swimming, due to the use of soft and elastic materials that fail to prevent lens movement and torsional displacement.
Innovation Solution
The design incorporates rigid frames for the lenses, a lower-rigidity connecting element to adapt to the nasal root, and a soft seal element for eye-socket fit, each made from specific materials like elastomeric polypropylene, thermoplastic rubber, and silicone, ensuring fixed positioning and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support structure is made of soft and elastic material to adapt to eye-sockets, then comfort and adaptability are improved, but the ability to maintain fixed position and prevent lens movement deteriorates
Solution Approach 1:
The support structure is divided into multiple segments: rigid frames for lens support, a first connecting element for nasal root connection, and a soft second element for eye-socket sealing. Each segment performs a specific function, allowing the structure to be both adaptable and stable.
Solution Approach 2:
Different parts of the support structure have different rigidity properties tailored to their specific functions. The frames are rigid to maintain lens position, the first connecting element has intermediate rigidity to adapt to the nasal root, and the second element is soft to seal the eye-sockets comfortably.
2Stability of the object's composition
If the support structure is made in two parts connected by non-extensible strip to prevent lens movement, then lens position stability is improved, but torsional rigidity is insufficient causing loss of initial position
Solution Approach 1:
The first connecting element is designed with specific torsional rigidity properties to resist twisting forces while maintaining adaptability to the nasal root shape, solving the problem of insufficient torsional resistance in conventional non-extensible strips.
Solution Approach 2:
The support structure uses composite construction with rigid frames made of rigid material and connecting elements made of material with lower rigidity, creating a composite structure that provides both stability and necessary flexibility.
3Stability of the object's composition
If rigid frames are used to maintain lens shape and position, then structural stability is improved, but adaptability to user's nasal root deteriorates
Solution Approach 1:
The support structure is segmented into rigid frames that maintain lens shape and softer connecting elements that adapt to the nasal root, allowing each part to optimize its specific function without compromising the other.
Solution Approach 2:
The rigid frames provide local stability for lens support while the first connecting element provides local adaptability to the nasal root, with each zone having properties optimized for its specific requirement.

AI summary
Swimming goggles (10) having two lenses (11), a pair of rigid frames (13) supporting the lenses, a rigid first connecting element (15) between the pair of frames (13), and a soft second element (12) distinct from the first connecting element (15) and from the frames (13). The frames (13) can have a rigidity chosen to ensure a shape of a rim of the lenses (11) and to support end buckles for connection between the goggles (10). The first connecting element (15) can have a lower rigidity than the frames (13), adapting the first connecting element (15) to a shape of a user's nasal root but opposing traction forces tending to modify a distance between the lenses (11) and the torsional torques tending to modify relative lying planes of the two lenses (11). The second element (12) can have two annular portions (16) and a connecting bridge (24) therebetween.
