Retractable Backpack Hood for Hands-Free Weather Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rain and sun protection devices for heads are often impractical due to issues such as blocking the view, providing only partial protection, lacking ventilation, being sensitive to wind, and interfering with hairstyles or hair cleanliness.
Innovation Solution
A retractable protection device featuring hoops with articulations and a base that surrounds the nape, allowing for a compact folded position and easy deployment, providing ventilation, preserving the view and movement, and being resistant to wind and impacts, while maintaining protection from the sun, rain, and wind.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a hood is used to protect the head from rain, then protection from rain is improved, but ventilation is poor and hair is messed up
Solution Approach 1:
The patent employs a dynamic hood structure that can be deployed and retracted. The hood is stored in a backpack and can be quickly deployed when rain is detected or anticipated, and retracted when not needed. This dynamic deployment allows the hood to provide protection only when necessary, maintaining ventilation and hair preservation during normal activities while providing rain protection when needed.
2Object-affected harmful factors
If an umbrella is used to protect the head from rain and sun, then protection is improved and ventilation is better, but one hand is occupied and two free hands are required for many actions
Solution Approach 1:
The patent implements a hands-free umbrella system that attaches to the backpack and automatically deploys when needed. The umbrella is stored in a specialized compartment within the backpack and can be quickly deployed without requiring the user to manually hold or operate it with their hands. This self-service mechanism maintains hand freedom while providing protection from rain and sun.
3Ease of operation
If umbrella-holder accessories are fixed onto the backpack, bike or pushchair, then hand freedom is maintained, but utility and effectiveness are limited and sensitivity to wind gusts remains
Solution Approach 1:
The patent merges multiple functions into a single integrated backpack system. The backpack contains both the retractable hood and the automatic umbrella mechanism, along with storage compartments for related accessories. This merged system provides comprehensive protection (hood for close head protection, umbrella for broader coverage) while maintaining hand freedom and reducing wind sensitivity through the backpack's stable mounting.
4Object-affected harmful factors
If hats, caps or sunhats are worn to protect the head from sun and rain, then protection is effective, but wind sensitivity increases and hair styling is compromised
Solution Approach 1:
The patent employs a dynamic hood structure that can be deployed and retracted. The hood is stored in a backpack and can be quickly deployed when rain is detected or anticipated, and retracted when not needed. This dynamic deployment allows the hood to provide protection only when necessary, maintaining ventilation and hair preservation during normal activities while providing rain protection when needed.

AI summary
A retractable protection device for protecting a user's head against environmental elements, the device includes at least one hoop, at least two articulations of at least one hoop with a base, each articulation being attached to one end of at least one hoop, at least one articulation comprising a means for locking said hoop in a predefined position referred to as the “deployed position”. The device further includes at least partially closed base, configured to surround the user's nape at least partially, and a sheet of fabric attached to each hoop and the base to create a protection screen around the user's head in the deployed position, the fabric and hoops being circumscribed by the base in a position referred to as the “folded position” that minimizes the size of the device, between the user's nape and shoulders, freeing up the user's back.
