Wire Strap Adjustment Device for Symmetric Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustment devices for portable elements, such as snow goggles and diving masks, are cumbersome and difficult to adjust while in use, often leading to non-symmetric and inefficient securing due to the need to manually slide and position adjustment units, which can result in incorrect positioning and damage to straps.
Innovation Solution
An adjustment device featuring pairs of wire-shaped elements with mobile adjustment units and mechanical coupling means that allow for quick and symmetrical adjustment by modifying the deviation paths and separating distances, enabling easy length adjustment without removing the portable element, and facilitating easy replacement of worn or damaged straps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single adjustment unit with sliding mechanism is used, then the device can adjust strap length, but the adjustment process becomes long and laborious requiring manual sliding and positioning
Solution Approach 1:
The single adjustment unit is divided into two separate adjustment units, each independently controlling one wire-shaped element. This segmentation allows simultaneous independent adjustment of both sides, eliminating the sequential sliding operation and reducing adjustment time while maintaining ease of operation.
Solution Approach 2:
The adjustment units are designed to be mobile along the wire-shaped elements, enabling dynamic adjustment during use. The mobile adjustment units can be quickly positioned and fixed, providing fast adjustment without removing the portable element, thus reducing adjustment time while maintaining operational ease.
2Ease of operation
If manual sliding adjustment is used, then the strap length can be modified, but the adjustment becomes non-symmetric and inefficient leading to incorrect positioning
Solution Approach 1:
The device uses two independent adjustment units that can be adjusted asymmetrically to accommodate individual user needs, while the symmetric wire-shaped element structure ensures balanced force distribution. This allows easy asymmetric adjustment operation while achieving symmetric and precise positioning of the portable element.
Solution Approach 2:
The adjustment units are designed to be easily adjustable by the user without requiring precise manual sliding skills. The mobile adjustment units with deviation paths enable users to achieve correct positioning through simple pull and fix operations, making the adjustment process self-serviceable and ensuring accurate positioning without specialized skills.
3Reliability
If flexible woven strip or silicone-based straps are used, then the portable element can be secured, but the straps become difficult to replace when worn or damaged
Solution Approach 1:
The adjustment units are designed with universal mechanical coupling means that work with different wire-shaped element materials. This universality allows the same adjustment mechanism to function with various strap types, maintaining securing efficiency while enabling easy replacement of worn or damaged wire-shaped elements by simply detaching and reattaching them to the adjustment units.
