Swimming Goggle Eyepiece Flat Lens Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swimming goggles suffer from refraction problems due to non-flat lenses, limited visual fields, hydrodynamic encumbrance, instability, and discomfort, particularly during competitive swimming and long training sessions, due to bulky designs and poor watertightness.
Innovation Solution
The design features eyepieces with a truncated pyramid shape and irregular polygonal base, including a polygonal plan-shaped flat front lens and a set of connected flat lenses, providing a wide panoramic vision without obstacles, and a peripheral adhesion lip for secure fit, made from rigid transparent plastic with anti-fogging and anti-scratching properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If curved lenses are used to extend visual field, then lateral vision is improved, but image quality deteriorates due to out-of-focus images and refraction problems
Solution Approach 1:
The eyepiece is divided into multiple flat lens segments (front lens, lateral lenses, upper lenses, lower lenses) arranged in a truncated pyramid configuration. Each segment remains flat to maintain optimal image quality while the segmented arrangement collectively provides an extended panoramic visual field of nearly 180 degrees.
2Measurement precision
If flat lenses are used to eliminate refraction problems, then image quality is improved, but visual field is limited
Solution Approach 1:
The invention transitions from traditional single-plane flat lenses to a three-dimensional truncated pyramid structure composed of multiple flat lens segments. This spatial arrangement in multiple dimensions allows each lens to remain flat for optimal image quality while the collective configuration extends the visual field panoramically.
3Reliability
If bulky eyepieces are used to ensure watertightness, then sealing is improved, but hydrodynamic performance deteriorates
Solution Approach 1:
The eyepiece geometry is changed from traditional bulky curved shapes to a streamlined truncated pyramid form with flat surfaces. This parameter change in shape and structure reduces hydrodynamic drag significantly while maintaining watertightness through precision sealing elements positioned at the periphery of the compact design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution offers enhanced stability, reduced hydrodynamic drag, and improved watertightness, allowing for a wide, distortion-free visual field of almost 180°, making it suitable for various swimming styles without compromising comfort or performance.
Implementation Method 1
under-water the main problem is that a non-flat lens leads to refraction problems, since water and air have very different refractive indexes, negatively affecting the vision
