Swimming Goggle Strap Buckle with Self-Locking Pressing Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming goggles with adjustable head straps are cumbersome to assemble and require complex adjusting mechanisms, often necessitating multiple steps and components that are difficult to manage.
Innovation Solution
The design features a strap device with buckles, a head strap, and pressing members that automatically return to abut stop-grooves, allowing the head strap to move in a single direction to tighten, simplifying adjustment and assembly by using a connecting base with a peg, engaging arm, and shaft blocks that lock into place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional adjusting buckles with multiple components are used, then the head strap can be adjusted, but the assembly becomes complicated and the adjustment process becomes troublesome
Solution Approach 1:
The patent combines the pressing bar, stop-grooves, and locking mechanism into an integrated buckle assembly. The pressing bar is directly formed as part of the buckle structure, eliminating the need for separate adjusting components. This merging of functions allows the head strap to be adjusted by simply pressing the integrated bar, greatly simplifying the adjustment process while maintaining the necessary functionality.
Solution Approach 2:
The buckle assembly features self-locking functionality where the pressing bar automatically engages with the stop-grooves to secure the head strap at the desired position. The design allows users to adjust the strap by pressing the bar, and upon release, the bar automatically locks into place without requiring additional steps or components. This self-service mechanism eliminates the need for complex manual locking procedures.
2Manufacturing precision
If manual adjustment of head strap is required, then positioning can be achieved, but the user must take the goggles up and down multiple times which is troublesome
Solution Approach 1:
The pressing bar mechanism allows users to adjust the head strap while the goggles remain on their head. By simply pressing the bar, users can move it along the stop-grooves to achieve the desired position, and the bar automatically locks in place. This eliminates the need to repeatedly take the goggles on and off for adjustment, saving time and improving convenience while maintaining precise positioning capability.
Solution Approach 2:
The pressing bar is designed to be dynamically movable along the stop-grooves when pressed, allowing continuous adjustment of the head strap length. The bar transitions from a locked static position to a movable state when pressure is applied, enabling users to slide it to the desired position and then automatically lock again. This dynamic mechanism provides precise adjustment without requiring the goggles to be removed.
3Reliability
If multiple adjusting components are used, then the head strap can be secured, but the assembly process becomes troublesome
Solution Approach 1:
The patent integrates the pressing bar, stop-grooves, and locking features into a single buckle assembly that is directly attached to the goggle frame. This merging of components simplifies the manufacturing process by reducing the number of separate parts that need to be assembled. The integrated design maintains reliable head strap securing while making the overall assembly process more straightforward and less troublesome.

AI summary
Swimming goggles have a left frame, a right frame, lenses received in the left frame and the right frame, and a strap device. The strap device includes buckles respectively assembled on the left frame and the right frame, and a head strap extending through the buckles and defining a plurality of stop-grooves therein. Each buckle includes a connecting base, a peg locking with the connecting base, and a pressing member. The connecting base defines an opening therein, a guiding post being formed on a side of the opening for movably receiving the head strap. An engaging wall is formed on the connecting base, and an engaging arm is formed on the engaging wall for assembling to the left frame and the right frame. A block is formed on the pressing member and extends through the opening when assembled.
