Spring-Loaded Hood Band for Eyewear Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hooded wearing apparel with tightly cinched hoods often interfere with eyewear, causing vision impairment when the wearer turns their head, as the hood can push or cover the eyewear, leading to an unnatural body twist to maintain clear vision.
Innovation Solution
A spring-loaded hood band with an inverted-U shape is integrated into the drawstring channel of the hood, providing a customizable fit that maintains the hood's shape while allowing for wider flexibility and preventing interference with eyewear, enhancing peripheral visibility and wind sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hood is tightly cinched to maintain shape and provide wind protection, then wind sealing and hood shape stability are improved, but interference with eyewear and vision impairment occur
Solution Approach 1:
The hood band is divided into multiple spring segments that can independently adjust to accommodate eyewear while maintaining overall hood tension and shape
Solution Approach 2:
The spring-loaded hood band provides dynamic adjustment capability, allowing the hood to adapt its tension and shape in response to the presence of eyewear, thereby preventing interference while maintaining wind protection
2Reliability
If the hood is tightly cinched to prevent wind entry, then wind protection is improved, but peripheral visibility is reduced due to hood obstruction
Solution Approach 1:
The spring-loaded hood band dynamically adjusts hood tension and positioning, allowing the hood to shift away from the wearer's peripheral vision area while maintaining effective wind sealing around the face
3Stability of the object's composition
If the hood is cinched tightly to maintain a set shape, then hood shape stability is improved, but flexibility and comfort are reduced
Solution Approach 1:
The spring-loaded mechanism enables the hood band to dynamically adjust between maintaining a set shape for wind protection and becoming more flexible to accommodate different wearing conditions and user comfort requirements
Solution Approach 2:
The spring-loaded hood band can change its tension and rigidity parameters to adapt between maintaining a rigid set shape and becoming more flexible for comfort and adaptability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The hood band ensures comfortable wear of eyewear by preventing hood interference, improving visibility and wind protection by allowing the hood to be adjusted for better fit and reduced obstruction when turning the head.
