Hood with Triangular Connector System for Adjustable Face Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hoods fail to provide effective protection against severe weather while maintaining unobstructed vision and breath, as they either expose the face too much or too little, and lack adjustable mechanisms to optimize coverage.
Innovation Solution
A hood with three groups of connectors positioned in a triangular shape around the face opening edge, allowing for adjustable coverage by tightening or loosening, ensuring good eyesight and breathability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the hood opening is made large to maintain good eyesight and breathability, then vision and breathing are improved, but protection against severe weather deteriorates
Solution Approach 1:
The hood opening edge is segmented into multiple adjustable sections through three groups of connectors (first group at vertex under chin, second group at left side vertex, third group at right side vertex). This segmentation allows different portions of the opening to be adjusted independently, enabling the wearer to optimize both protection and visibility/breathability by selectively tightening or loosening specific connector groups based on weather conditions and personal needs.
2Object-affected harmful factors
If the hood opening is made small to provide protection against severe weather, then protection is improved, but eyesight and breathability deteriorate
Solution Approach 1:
The hood opening transitions from a static fixed size to a dynamic adjustable size through the connector system. The three groups of connectors (positioned at triangular vertices) enable real-time modification of the opening perimeter length, allowing the wearer to dynamically adapt the hood's protective coverage and face exposure area according to changing weather conditions, activity level, and visual requirements.
3Device complexity
If fixed hood design is used, then device complexity is reduced, but adaptability to different weather conditions deteriorates
Solution Approach 1:
The hood is divided into adjustable segments controlled by three connector groups positioned at triangular vertices around the face opening. This segmentation adds minimal complexity while maximizing adaptability, as each connector group can be independently adjusted to modify the opening perimeter and face exposure area, allowing the same hood structure to adapt to various weather conditions from mild to severe.

AI summary
A garment with a hood, wherein three groups of connectors are installed on and around the opening edge of the hood surrounding the face of the wearer. Each group of the three groups of connectors are positioned at a vertex of a triangle shape. When the hood has been put on the head of the wearer, the exposure area of the wearer's face is to be adjusted to be smaller or larger, by tightening or untightening one pair, or more than one pair of the connectors. When tightened, the hood forms better thermo-insulation, and provides better protection for the user against severe weather including cold, wind and snow.
