Swimming Goggle Lens Mounting Tabs and Rib Frame

Solution Overview

Problem

Existing swimming goggles often experience lens displacement due to frame bending under strap tension, leading to accidental lens dropout and potential damage.

Innovation Solution

The goggles feature radially projecting tabs on the lenses that engage with corresponding elements in the frame for stable and removable mounting, along with a rib structure in the frame to absorb bending forces, preventing lens dropout and maintaining lens stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the frame is made rigid to hold lenses securely, then lens stability is improved, but the frame cannot accommodate strap tension without bending

Engineering Contradiction:

Improvelens stabilityVSAvoidframe flexibility

Core Design Contradiction:

Stability of the object's compositionVSStrength

Solution Approach 1:

The frame is divided into two distinct parts: a rigid part for holding lenses and a soft part for contacting the swimmer's face. This segmentation allows each part to have different mechanical properties - the rigid part maintains lens stability while the soft part accommodates strap tension through bending without transmitting forces to the lenses.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The soft part of the frame acts as an intermediary element between the rigid part and the swimmer's face. It absorbs the bending forces generated by strap tension, preventing these forces from reaching and damaging the lenses while still maintaining secure attachment to the face.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the frame is made soft to accommodate face contact, then adaptability is improved, but the frame bends under strap tension causing lens displacement

Engineering Contradiction:

Improveface contact adaptabilityVSAvoidlens stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

This segmentation allows each part to have different mechanical properties - the rigid part maintains lens stability while the soft part accommodates strap tension through bending without transmitting forces to the lenses.

3Stability of the object's composition

If lenses are firmly fixed in the frame, then lens stability is improved, but lens replacement becomes difficult

Engineering Contradiction:

Improvelens stabilityVSAvoidlens replacement ease

Core Design Contradiction:

Stability of the object's compositionVSEase of repair

Solution Approach 1:

The lens mounting system transitions from a static fixed connection to a dynamic removable connection. The tabs on the lenses engage with corresponding elements in the frame through a mechanism that provides firm holding during use but allows easy removal when replacement is needed, achieving both stability and serviceability.

Inventive Principle:

Principle #15Dynamics

AI summary

Swimming goggles, comprising a frame (1) in which mounting seats (101, 101') are provided for a pair of lenses (5, 5'); each of the lenses (5, 5') comprises at least a pair of radially projecting tabs (105, 205) adapted to engage in corresponding elements (6, 9) for positioning and removable fastening, these elements being provided in practically diametrically opposite positions in each of the seats (101, 101') of the frame (1).
