Segmented Head Band for Protective Equipment Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head bands for protective equipment like welding masks and safety helmets often fail to comfortably contact the forehead and back of the head, causing inconvenience due to inadequate design, particularly with a single band part struggling to conform to the head's shape and difficulty in adjusting to individual gradients.
Innovation Solution
A head band with a first band part featuring arc-shaped sections for the forehead and adjustable third sections for the back, along with length-adjustable second and third band parts for the crown, ensuring close contact and comfort through customizable fit and distribution of weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single first band part is used to surround the circumference of the head, then the structure is simple, but it cannot comfortably contact the forehead and back of the head, causing wearer inconvenience
Solution Approach 1:
The first band part is divided into multiple sections: a first section for the forehead, a second section for the top of the head, and a third section for the back of the head. Each section can be independently adjusted or positioned to conform to different contours of the head, enabling comfortable contact across all regions while maintaining a unified overall structure.
Solution Approach 2:
The head band incorporates adjustable mechanisms that allow the wearer to dynamically modify the gradient and positioning of each section to match their unique head shape. This dynamic adaptability ensures comfortable contact without requiring a completely complex fixed structure for every possible head contour.
2Adaptability or versatility
If a single second band part is provided to surround the crown of the head, then the device complexity is reduced, but it has difficulty conforming to the head of the wearer because adjusting a gradient is difficult
Solution Approach 1:
The second band part is designed with adjustable gradient capabilities, allowing it to dynamically adapt to different head shapes and crown contours. The adjustment mechanism enables the band to conform to various gradients without requiring excessive structural complexity.
Solution Approach 2:
The second band part allows for parameter adjustments in terms of gradient and positioning to match the wearer's head shape. By changing these parameters, the band achieves better conformability without fundamentally altering the overall device structure.
3Area of stationary object
If the first band part is designed to surround the circumference of the head, then it provides overall coverage, but it cannot comfortably come into close contact with the forehead and back of the head
Solution Approach 1:
The first band part is segmented into distinct sections (first section for forehead, second section for top, third section for back), each optimized to contact specific regions of the head. This segmentation allows the band to maintain overall circumferential coverage while ensuring comfortable contact in each specific area through localized design adjustments.

AI summary
Disclosed is a head band to assist a user in conveniently wearing head protective equipment on the head. The head band includes a first band part configured to surround the circumference of the head. The first band part includes first sections located at opposite lateral regions of the head and each provided with a coupling piece for coupling with the welding mask, a second section located on a front region of the head, the second section taking the form of an arc-shaped section having a predetermined radius of curvature when unrolled and being adapted to come into close contact at a predetermined gradient with the forehead, and third sections located at a rear region of the head, the third sections being connectable to each other to enable adjustment in the length of the third sections. The first band part comfortably comes into close contact with the forehead, providing wearer comfort.
