Swimming Goggle Top Anchor for Water Resistance Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swimming goggles experience water leakage and discomfort due to downward force from water resistance, which is inadequately addressed by existing designs that either compromise sealing or require excessive strap tightening, and often require a swimming cap for functionality.
Innovation Solution
The design incorporates a top anchor extending upward and rearward from the main body, coupled with a strap and adjustable to fit various head contours, providing improved resistance to water pressure and stability without the need for a swimming cap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the profile of the lenses is lowered to reduce downward force, then water resistance is reduced, but the volume inside the lenses and gasket thickness are reduced resulting in discomfort and indentations
Solution Approach 1:
The patent introduces a top anchor extending upward from the lens assembly, adding a vertical dimension to the force distribution system. This allows the goggle to resist downward water pressure through a higher placement point on the head, rather than relying solely on lowering the lens profile or increasing strap tension.
Solution Approach 2:
The top anchor acts as an intermediary element between the water pressure acting on the goggle and the swimmer's head. It transfers and distributes the downward forces to a higher point on the head (above the ears), preventing direct pressure on the eyes and temples while maintaining sealing effectiveness.
2Reliability
If the strap is tightened excessively to prevent leakage, then water sealing is improved, but discomfort and indentations around the eyes are increased
Solution Approach 1:
The patent extracts the primary sealing function from the strap and relocates it to the top anchor-goggle interface. The strap's role is reduced to secondary retention, allowing it to be worn comfortably without excessive tension while the top anchor provides the main sealing force at a point that doesn't compress the facial tissues.
3Stability of the object's composition
If a goggle-fixing-piece is attached to the gaskets to prevent rotation, then outward rotation is resisted, but the moment arm is limited and the fixing-piece deforms compromising gasket sealing
Solution Approach 1:
The top anchor extends upward from the top of the lens assembly, creating a much longer moment arm that reaches above the ears. This vertical extension provides superior rotational stability compared to fixing pieces attached to the gaskets at eye level, while the rigid construction prevents deformation that would compromise sealing.
4Device complexity
If a single goggle-fixing-piece connects the two lenses, then the structure is simplified, but the width of the goggles cannot be adjusted for different users
Solution Approach 1:
The top anchor serves multiple functions: it provides rotational stability, prevents downward sliding, and acts as a sealing element. The adjustable nose bridge and ear cup positioning allow the same basic structure to accommodate different head sizes and shapes, achieving versatility without requiring multiple fixing pieces.

AI summary
Swimming goggles includes a main body and a top anchor. The main body includes a lens unit, at least one gasket, and a strap. The at least one gasket is made of soft material and is disposed on a rear side of the lens unit for abutting a face of a wearer. The strap is coupled with the lens unit. A top anchor disposed on top of the main body. The top anchor includes a front end connected to the top portion of the lens unit and extends upward and rearward. Top anchor is configured to abut an upper portion and a rear portion of a head of the wearer wearing the swimming goggles. Thus, the swimming goggles can withstand the water resistance to improve the wearing stability while preventing water leakage into the swimming goggles.
