Swimming Goggles Soft Frame Segmentation for Comfort and Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swimming goggles with hard frames can be uncomfortable and prone to water leakage due to their rigidity, which does not accommodate the varying face widths of users effectively.
Innovation Solution
The goggles feature soft frames with inner, outer, and intermediate surfaces, connected by a hard holding frame system with strap elements and link portions, allowing for adjustable and secure fitting to prevent water seepage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard frames are used to fix lenses reliably, then lens fixing reliability is improved, but user comfort deteriorates due to rigid pads
Solution Approach 1:
The goggle frame is divided into two distinct parts: hard holding frames for lens fixation and soft frames for user comfort. This segmentation allows each part to perform its specific function optimally without compromise.
Solution Approach 2:
The goggle employs a composite structure combining hard material (for holding frames) and soft material (for frames contacting user's face). This composite approach enables simultaneous achievement of structural reliability and comfort.
2Stability of the object's composition
If hard frames are used to maintain structural integrity, then structural stability is improved, but adaptability to different face widths deteriorates
Solution Approach 1:
The frame system is segmented into rigid holding frames (for structural stability) and flexible soft frames (for adaptability). This allows the structure to maintain integrity while adapting to different user geometries.
Solution Approach 2:
The soft frames introduce dynamic flexibility to the otherwise rigid structure, enabling the goggle to adapt its shape to different face widths while the hard holding frames maintain overall structural stability.
3Stability of the object's composition
If rigid frames are used to prevent deformation, then shape stability is improved, but water tightness deteriorates due to inability to fit closely
Solution Approach 1:
The frame is segmented into hard holding frames that maintain shape stability and soft frames that conform to the user's face for water tightness. This segmentation resolves the contradiction between rigidity and sealing.
Solution Approach 2:
The soft frames act as flexible shells that can deform to match the user's face contours, ensuring water tightness while the hard holding frames provide the necessary structural support.

AI summary
Swimming goggles include a left frame, a right frame, hard holding frames and strap elements. A connecting portion connects the left frame and the right frame. The left frame and right frame are both formed of soft material. Each of the left frame and the right frame includes an inner surface, and an outer surface, and an intermediate surface between the inner surface and the outer surface. Lenses are received between the inner surfaces and the outer surfaces of the left frame and right frame. Hard holding frames respectively clamp the left frame and right frame. Strap elements are formed on outward lateral sides of the hard holding frames for receiving a head strap. Pads are provided on the left frame and the right frame for comfortably contacting users. The connecting portion is flexible so that fitting to various users with different face profiles without hazard of water leakage.
