Rotatable Helmet Chin Strap Divider Prevents Twisting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional helmet chin strap dividers fail to adjust the length of chin straps from the front and rear of the helmet independently, leading to twisting and reduced contact with the wearer's face, especially for individuals with longer faces.
Innovation Solution
A helmet chin strap divider with a first support connected to the front chin strap and a second support rotatably coupled to the rear chin strap, allowing adjustable angles and lengths to prevent twisting, featuring a protrusion portion with hooks, a concave portion, and a locker mechanism for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the chin straps are overlaidly collected under the wearer's ear without independent length adjustment, then the helmet structure is simple, but it is impossible to correspond to various head shapes and causes interferences between the chin straps and the ear
Solution Approach 1:
The patent applies the dynamics principle by making the chin strap divider rotatable rather than fixed. The divider can rotate to adjust the angle between the front and rear chin straps, allowing adaptation to different head shapes and sizes. This dynamic adjustment capability enables the same structure to accommodate various users without increasing overall structural complexity.
2Stability of the object's composition
If the chin straps are collected at one position with a fixed divider, then the device structure is simple, but the angle between chin straps is drastically varied causing the chin straps to twist
Solution Approach 1:
The divider is designed to be rotatable rather than fixed, allowing it to dynamically adjust the angle between chin straps. This prevents drastic angle variations that cause twisting while maintaining a relatively simple structural composition.
Solution Approach 2:
The patent changes the angular parameter of the divider to match the angle between chin straps. By adjusting this parameter, the system prevents strap twisting while maintaining structural simplicity. The rotatable design allows the parameter to be changed as needed without complicating the overall structure.
3Reliability
If the chin straps are collected at one position, then the device structure is simple, but the degree of contact between the chin straps and the wearer's face is decreased
Solution Approach 1:
The rotatable divider enables dynamic adjustment of chin strap positioning to optimize contact with the wearer's face. This improves reliability of the helmet fit without requiring a complex fixed-position adjustment mechanism.
Solution Approach 2:
The chin strap system is segmented into front and rear straps that can be independently adjusted via the rotatable divider. This segmentation allows each strap to be positioned optimally for face contact while keeping the overall structure relatively simple.
