Swimming Goggle Buckle Set with Spring-Loaded Clasps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buckle designs, such as tri-glide buckles, struggle to maintain the strap at a desired length due to the elastic rebound of rubber straps, causing the strap to easily come off the buckle during length adjustment.
Innovation Solution
A buckle set comprising a buckle seat with springs, barriers, pivot slots, and strap slots, along with two corresponding clasps with press studs and bumps, which securely positions the strap and allows for easy adjustment by using the elasticity of the springs to maintain the strap in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tri-glide buckle is used to adjust strap length, then the strap can be positioned at a desired length, but the elastic rebound of the rubber strap causes it to come off the buckle easily
Solution Approach 1:
The buckle is divided into two separate clasps that can independently engage with the strap ends. Each clasp has its own prong and engagement mechanism, allowing the strap to be secured at multiple points rather than relying on a single engagement point, thereby preventing the strap from slipping off due to elastic rebound.
Solution Approach 2:
The strap ends are pre-inserted into the clasps before final engagement. The design allows the strap to be partially positioned and then locked in place by the engagement mechanism, ensuring that the elastic rebound force is counteracted before the strap can slip off.
2Adaptability or versatility
If the strap is made of elastic rubber for comfort, then it provides flexibility and comfort, but the rebound property causes the strap to come off the buckle during adjustment
Solution Approach 1:
The engagement mechanism is extracted from the traditional single-hole buckle design and implemented as separate clasp components with specific engagement features. This allows the elastic strap to be securely held by the clasp structure rather than relying solely on friction or simple hole engagement, maintaining flexibility while preventing slippage.
3Ease of manufacture
If the buckle design is simplified for ease of manufacture, then production cost decreases, but the ability to securely hold the elastic strap at desired length is compromised
Solution Approach 1:
The buckle design incorporates specific local features such as prongs, slots, and engagement surfaces in critical areas where strap retention is needed, while other areas maintain simpler geometry for easy manufacturing. The clasps have precisely formed engagement features locally, but the overall structure remains relatively simple and cost-effective to produce.

AI summary
A buckle set, which fits onto a strap for adjusting the strap to a desired length, generally fits onto the strap attached to goggles of almost any application, such as swimming goggles, scuba mask, or dust and wind goggles. Specifically, a buckle set allows a strap to easily and quickly be adjusted to a desired length from its two ends.
