Swimming Goggles with Backup Ring and Hook Channel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swimming goggles cause discomfort due to direct contact with hard frames, may leak water, and obstruct the visual field, especially for swimmers with longer eyelashes.
Innovation Solution
The goggles feature frame bodies with inner and outer peripheral faces, hook channels, protective pads, and backup rings that fit snugly around the eye sockets, reducing water resistance and providing an extended visual field by inclining lenses and using arc surfaces to fit the nose bridge without adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional racing swimming goggles use a hard frame material to integrate lenses and frame, then manufacturing precision and structural strength are improved, but wearer comfort deteriorates due to direct contact with hard material
Solution Approach 1:
The frame is divided into two distinct parts: a hard frame body for structural strength and lens integration, and a separate soft protective pad for comfort. This segmentation allows each component to fulfill its specific function without compromise.
Solution Approach 2:
A soft protective pad is introduced as an intermediary element between the hard frame and the wearer's face. This mediator provides comfort while the hard frame maintains its structural integrity and optical alignment.
2Ease of operation
If conventional racing swimming goggles attach protective pads in a forward direction on the frame, then wearer comfort is improved, but water resistance deteriorates because the frame sticks out of the forehead
Solution Approach 1:
The protective pad attachment direction is changed from forward (horizontal dimension) to backward (toward the rear of the head). This dimensional change allows the frame to sit flush against the forehead, reducing water resistance while maintaining comfort through the soft pad material.
3Ease of manufacture
If conventional racing swimming goggles incline lenses with respect to wearer's eyes to fit the frame, then manufacturing is simplified, but visual field deteriorates because corners of eyes are blocked by the frame
Solution Approach 1:
The lens inclination is optimized locally to match the wearer's eye position and orientation, while the frame remains properly positioned on the forehead. This localized adjustment ensures both manufacturing feasibility and maximum visual field coverage.
4Device complexity
If conventional racing swimming goggles use a simple frame design without backup rings, then device complexity is reduced, but reliability deteriorates due to water leakage and incomplete attachment to the face
Solution Approach 1:
Backup rings are added to the frame structure to provide an additional sealing layer before water can penetrate. These rings act as a preventive measure against water leakage, enhancing reliability without significantly complicating the overall design.

AI summary
Swimming goggles comprise a left frame body, a right frame body, lenses, protective pads and head strap bases, wherein each of the left and right frame bodies has an inner peripheral face and an outer peripheral face, and the inner peripheral face forms a hook channel therealong; each of the protective pads are attached to the inner peripheral faces and has a face contact portion and a connecting portion, characterized in that a backup ring is disposed between the connecting portion and the hook channel, and has a first peripheral face and a second peripheral face, such that the first peripheral face integrally encompasses the hook channel of the inner peripheral face and also the second peripheral face forms with the connecting portion, thereby, the swimming goggles could be worn comfortably in swimming.
