Solution Overview

Problem

Conventional swimming goggles cushion pads apply direct pressure on the outer periphery of the eye socket, causing discomfort and potential water seepage due to their inability to conform to the unique contour of the eye socket, leading to increased tightening force and pressure on blood circulation.

Innovation Solution

A cushion pad with a face-attaching portion that features a wavy inner ring surface matching the eye socket's contour, combined with independent buffering bodies formed by first and second supporting members and joints, which absorb and distribute squeezing forces to conform to the eye socket's shape, reducing pressure and preventing water seepage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the headband tightening force is increased to make the face-attaching portion conform to the eye socket contour, then the anti-seepage effect is improved, but the pressure on the outer periphery of the eye socket increases causing discomfort and affecting blood circulation

Engineering Contradiction:

Improveanti-seepage effectVSAvoidpressure on eye socket

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The cushion pad employs local quality by creating a wavy inner ring surface with varying thickness at different locations. The thickness is greater at protruding portions (brow, cheekbone) and smaller at recessed portions (eye corner, nose bridge), allowing each region to provide appropriate buffering without requiring excessive overall tightening force.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The invention applies curvature by designing the inner ring surface with a wavy profile that matches the natural contour of the eye socket. This curved surface design allows the cushion pad to conform to the eye socket's shape, distributing pressure evenly and reducing localized stress points.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Reliability

If the face-attaching portion is made to conform to the wavy contour of the eye socket, then the fit and anti-seepage performance are improved, but the device complexity increases due to the need for multiple buffering bodies and supporting members

Engineering Contradiction:

Improvefit and anti-seepage performanceVSAvoidstructure with multiple buffering bodies

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The cushion pad is segmented into multiple independent buffering bodies distributed across the face-attaching portion. Each buffering body independently conforms to specific regions of the eye socket contour, allowing modular construction that achieves complex shaping through repeated simple units.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention merges multiple functions into the single buffering body structure. Each buffering body simultaneously provides contour conformation, pressure distribution, and buffering action, eliminating the need for separate components for each function and reducing overall device complexity.

Inventive Principle:

Principle #5Merging (Combining)

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 cushion pad effectively reduces pressure on the eye socket's contour, enhances comfort by minimizing tightening force, and prevents water seepage by conforming to the unique shape of the eye socket, providing improved fit and anti-seepage performance.

Implementation Method 1

A plurality of independent buffering bodies are provided between the outer peripheral surface of the connecting portion and the outer ring surface of the face-attaching portion, wherein each of the buffering bodies is jointly composed of a first supporting member, a second supporting member and a joint at an intersection of the first supporting member and the second supporting member. By independent actions of each buffering body, the face-attaching portion has different buffering resilience to different contact points on the periphery of the eye socket

Methodology Applied

Scientific EffectElastic deformation: Elasticity

Implementation Method 2

An inner ring surface of the face-attaching portion conforms to the depth and the height of the wavy curve of the outer periphery of the eye socket. That is, a first peak of the inner ring surface corresponds to a center of a brow, a second peak of the inner ring surface corresponds to a cheekbone, a first valley of the inner ring surface corresponds to an eye corner, and a second valley of the inner ring surface corresponds to a nose bridge
