Head Band with Multi-Point Support for Safety Helmets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head bands for industrial safety equipment, such as welding masks, often cause discomfort and headaches due to direct pressure on specific head regions, leading to reduced wearing convenience and stability.
Innovation Solution
A head band design featuring a band main body with a front supporting unit and a rotatable supporting band that contacts and supports the forehead and upper head regions at multiple points, along with an adjustable rear band for length adjustment, providing improved distribution of pressure and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the first support band and the second support band directly contact specific portions of the head, then the head band can support the helmet, but the wearing comfort deteriorates and discomfort/headache occurs due to concentrated pressure
Solution Approach 1:
The head band is divided into multiple support bands (first support band, second support band, third support band, fourth support band) that contact different regions of the head. This segmentation distributes the pressure from the helmet across multiple contact points rather than concentrating it on single areas, thereby maintaining support capability while improving wearing comfort.
Solution Approach 2:
Each support band is designed to contact a specific region of the head (frontal region, temporal region, occipital region) with appropriate local characteristics. The cushion member attached to the inner side surface of the length adjusting lever provides additional local cushioning at the occipital region, optimizing both support and comfort at each contact point.
2Stability of the object's composition
If the head band uses a fixed structure, then it provides stable support, but it cannot accommodate different head shapes and sizes
Solution Approach 1:
The head band incorporates a length adjusting lever that can rotate relative to the band main body, allowing the overall length of the head band to be dynamically adjusted. This enables the head band to adapt to different head circumferences while maintaining stable support through the distributed contact structure of multiple support bands.
Solution Approach 2:
The length of the head band is made adjustable by changing the parameter of band length through the length adjusting mechanism. The length adjusting lever can be positioned at different angles, changing the effective length of the head band to match different head sizes, thereby achieving both stability and adaptability.
3Ease of operation
If the cushion member is provided on the inner side surface of the length adjusting lever, then wearing convenience and comfort are improved, but the structure becomes more complex
Solution Approach 1:
The cushion member is integrated with the length adjusting lever by attaching it to the inner side surface of the lever. This merging combines the adjustment function of the lever with the comfort function of the cushion, allowing both length adjustment and occipital region cushioning to be achieved through a single integrated component, thereby minimizing structural complexity while improving comfort.
