Protective Hood With Elastic Strap For Head Size Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective garments with hoods struggle to accommodate varying head sizes, often obstructing vision due to hoods that are either too large, as they lack effective adjustment mechanisms.
Innovation Solution
The protective garment incorporates resilient straps made of elastic material, secured to the inside of the hood, which extend across the back and can stretch to fit the head, ensuring a secure and upright position without obstructing vision, with optional additional stabilizing straps for enhanced fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a one-size-fits-all hood is used in protective garments, then manufacturing simplicity and cost-effectiveness are improved, but the fit and vision for users with different head sizes deteriorate
Solution Approach 1:
The hood incorporates resilient straps that can dynamically adjust to different head sizes through elastic deformation. The straps are secured to the inside of the hood and can stretch to accommodate various head circumferences while maintaining a secure fit, allowing a single hood design to adapt to multiple users with different head dimensions.
Solution Approach 2:
The resilient straps utilize elastic material properties to change their dimensional parameters (length and tension) based on the head size they accommodate. This parameter change allows the same hood structure to provide appropriate fit for different head circumferences without requiring multiple sizes.
2Adaptability or versatility
If the hood is made larger to accommodate bigger heads, then adaptability to different head sizes is improved, but vision obstruction for smaller heads worsens
Solution Approach 1:
The resilient straps enable the hood to dynamically conform to the wearer's head size rather than forcing a fixed size. The elastic straps adjust their tension and position based on the head circumference, allowing the hood to fit snugly on smaller heads without obstructing vision while accommodating larger heads through the stretch capability of the elastic material.
3Adaptability or versatility
If existing adjustment mechanisms (press buttons, elastic straps) are added to the hood, then adaptability to different head sizes is improved, but device complexity increases
Solution Approach 1:
The invention uses resilient straps made of elastic material that are simple to attach to the inside of the hood. These straps provide an effective adjustment mechanism without requiring complex assemblies of multiple components. The elastic nature of the straps allows them to be secured with simple attachment methods while still providing reliable size adjustment capability.
