Solution Overview
Problem
Conventional goggles face issues with lens replacement difficulty, scratching, and insecurity, especially when worn with gloves, and are not suitable for sports that require helmets due to poor fit and weak mounting structures.
Innovation Solution
The design features a frame with stop holes and bifurcated belt arms equipped with a lock mechanism, allowing for secure and easy lens replacement, preventing accidental removal, and maintaining a tight fit even with helmets, using flexible soft elastic synthetic resin for shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single lens is removably mounted to the frame body with simple engaging protrusions, then the lens can be replaced, but it takes time and is difficult to engage when wearing gloves
Solution Approach 1:
The lens mounting structure is divided into multiple independent engaging protrusions distributed around the lens periphery, allowing the lens to be secured at multiple points simultaneously. This segmentation enables the lens to be engaged more quickly and securely when wearing gloves, as multiple points can be engaged in a single motion rather than requiring sequential engagement at individual points.
Solution Approach 2:
The engaging protrusions are pre-positioned on the frame body at optimal locations around the lens periphery. This preliminary arrangement allows the lens to be quickly and easily engaged without requiring complex manual manipulation, solving the problem of time loss during lens replacement while maintaining secure mounting.
2Adaptability or versatility
If the lens is frequently handled for replacement, then the lens can be changed according to conditions, but the lens surface is likely to be scratched by gloves
Solution Approach 1:
The engaging protrusions are extracted from direct contact with the lens surface and repositioned to engage with the lens mounting structure from the rear side. This extraction eliminates the harmful interaction between gloves and the lens surface during handling, as the engagement mechanism operates at the back of the lens rather than requiring contact with the front surface, thus preventing scratches while maintaining lens changeability.
Solution Approach 2:
The engaging protrusions act as intermediaries that facilitate lens mounting and removal without requiring direct hand contact with the lens surface. These protrusions mediate the interaction between the user's hands (wearing gloves) and the lens, allowing secure engagement while keeping the lens surface protected from contact and potential scratching.
3Reliability
If conventional lens mounting structures are used, then the lens can be secured, but the mounting strength is weak and the lens may be accidentally removed
Solution Approach 1:
Multiple engaging protrusions are merged into a unified mounting system that works together to secure the lens at multiple points around its periphery. This merging of multiple engagement points creates a distributed mounting structure that provides both strong security and ease of operation, preventing accidental removal while maintaining user-friendly replacement capability.
Solution Approach 2:
The engaging protrusions are strategically positioned at specific locations around the lens periphery where they provide maximum mounting strength and security. By optimizing the local distribution and positioning of these protrusions, the system achieves high reliability in preventing accidental removal while maintaining ease of operation for intentional lens replacement.
4Stability of the object's composition
If the frame body is made rigid for structural stability, then the goggles provide good support, but shock absorption is reduced
Solution Approach 1:
The frame body is constructed using composite materials that combine rigidity for structural stability with elastic properties for shock absorption. This composite construction allows the frame to maintain its shape and provide stable support while simultaneously absorbing shocks and impacts, resolving the contradiction between stability and shock absorption.
Solution Approach 2:
The material properties of the frame body are optimized by changing parameters such as elasticity modulus and damping characteristics. By adjusting these material parameters, the frame achieves the right balance between rigidity for structural stability and elasticity for shock absorption, allowing it to perform both functions effectively.

Implementation Method 1
a lock mechanism provided at an end of each of the bifurcated portions of the belt arms, wherein the respective first and second stop holes can be brought into either a lock state by the lock mechanisms of the belt arms to secure the frame, the lens, and the pair of left and right belt arms, or into an unlock state by the lock mechanisms where the lock state is released to separate the frame, the lens, and the pair of left and right belt arms
Implementation Method 2
using flexible soft elastic synthetic resin for shock absorption

AI summary
Goggles include a frame, a lens and a pair of left and right belt arms. On the frame a first stop hole is provided each left and right of a middle of each of an upper frame and a lower frame of the frame. The lens has an upper side and a lower side each of which is provided with a second stop hole at a position corresponding to each first stop hole in the frame. Each of the pair of left and right belt arms has bifurcated portions, and each end of the bifurcated portions is provided with a lock mechanism. The frame and the lens are placed on each other and the respective first and second stop holes are aligned. By the mechanisms of the belt arms, the first and second stop holes are brought into either a lock state to secure the frame, the lens and the pair of left and right belt arms, or an unlock state where the lock state is released to separate them.
