Retractable Hat Brim for Dynamic Sun Protection and Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hats with fixed brims fail to provide adequate sun protection throughout the day due to changing sun positions and angles, leading to skin damage and visibility issues, as a wide brim can obstruct sight.
Innovation Solution
A hat with a retractable brim that adjusts in real-time based on the position and angle of the sun relative to the wearer's face, using a detection unit and adjustment mechanism to optimize brim length for sun protection while maintaining visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a very wide hat brim is used for all-day protection, then sun protection effectiveness is improved, but sight obstruction increases and outgoing is affected
Solution Approach 1:
The hat brim is designed with adjustable length capability, allowing it to dynamically change from a wide brim for sun protection to a narrower brim for better sight. The brim can be extended or retracted based on the wearer's needs, transforming a static structure into a dynamic one that adapts to different situations throughout the day.
Solution Approach 2:
The length parameter of the hat brim is made changeable, enabling it to be adjusted to different lengths. This parameter change allows the brim to provide adequate sun protection when extended and reduce sight obstruction when retracted, resolving the contradiction between protection effectiveness and ease of operation.
2Object-affected harmful factors
If a fixed wide brim is used, then sun protection is adequate for low sun positions, but the brim becomes unnecessarily wide for high sun positions
Solution Approach 1:
The hat brim transitions from a fixed width design to a dynamic adjustable design, allowing the width to be modified based on sun position. When the sun is low, the brim extends to provide adequate protection; when the sun is high, the brim can be retracted to a narrower width, avoiding unnecessary complexity in the brim structure.
Solution Approach 2:
The adjustable brim mechanism serves multiple functions: it provides sun protection when extended and improves sight when retracted. This multi-functionality allows a single brim structure to adapt to different sun positions and wearer needs, eliminating the need for separate brim designs for different conditions.

AI summary
A hat and a hat brim length adjusting method are provided to solve the problem that the hat brim length of the existing sunscreen hats cannot be adjusted in real time. The present hat includes a hat body and a hat brim which is retractable in length; the hat further includes a power supply, an adjustment unit and a detection unit; wherein the detection unit is used for detecting relations between a position of the sun and a position of a wearer's face in real time; and the adjustment unit is used for adjusting a length of the hat brim according to the detection result. The hat brim length of the present hat is adjustable, so that the hat not only can block the sun for the wearer but also can provide a good sight angle for the wearer.
