Rotating Bridge Mechanism for Adjustable Swimming Goggle Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable bridges for swimming goggles often cause discomfort, interfere with the nose, inhibit suction, require excessive strength to adjust, and can inadvertently adjust while in use, particularly affecting children who lack the necessary hand strength.
Innovation Solution
The design features a bridging mechanism with a first and second bridging member that rotationally engage, allowing for adjustable distance between eyepieces through threaded engagement, and includes a stop mechanism to prevent unintended rotation, along with a strap connector system to secure the goggles effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bridge is made adjustable to accommodate various face sizes, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The bridge is designed with a rotatable connection between the first and second bridging members, allowing the bridge length to be dynamically adjusted by rotating one member relative to the other. This dynamic adjustment mechanism enables the bridge to adapt to various face sizes while maintaining a relatively simple overall structure.
Solution Approach 2:
The bridge is divided into two separate bridging members (first bridging member and second bridging member) that can rotate relative to each other. This segmentation allows independent adjustment of the bridge length without requiring a completely complex reconfigurable structure.
2Reliability
If the bridge adjustment mechanism requires secure engagement, then the reliability is improved, but the ease of operation deteriorates due to excessive strength required
Solution Approach 1:
The patent replaces complex mechanical fastening systems with a simpler rotational engagement system. The first and second bridging members engage through rotation rather than requiring screws, clips, or other complex fastening mechanisms, making adjustment easier while maintaining secure engagement.
Solution Approach 2:
The engagement mechanism is designed to change the friction and contact parameters between the bridging members during rotation. The curved surfaces and threading create optimal contact conditions that provide secure engagement during normal use while allowing easy rotational adjustment when needed.
3Ease of operation
If the bridge adjustment mechanism is simple, then the ease of operation is improved, but the reliability deteriorates due to inadvertent adjustment
Solution Approach 1:
The stop mechanism is designed to preemptively prevent inadvertent rotation of the bridging members. The stop portion and stop groove are positioned to engage before any unintended adjustment can occur, creating a preliminary barrier against unwanted movement while not interfering with deliberate adjustment actions.
Solution Approach 2:
The stop mechanism creates a periodic engagement pattern during rotation, where the stop portion intermittently engages with the stop groove at specific rotational positions. This periodic engagement provides stable positioning at discrete intervals while allowing controlled adjustment between positions.
4Adaptability or versatility
If the bridging members are designed to rotate for adjustment, then the adaptability is improved, but the object-generated harmful factors worsen due to interference with the nose
Solution Approach 1:
The bridging members are designed with curved surfaces instead of straight rigid structures. This curvature allows the bridge to conform to the natural contour of the user's nose and face, reducing pressure points and discomfort while maintaining the adjustable length capability through rotation.
Solution Approach 2:
The bridging members are designed with flexible or compliant characteristics that allow them to adapt to the user's facial geometry. The curved, rotatable design enables the bridge to flex and conform to individual face shapes, reducing interference and discomfort while providing adjustable fit.
