Hat Shield Pivot Assembly With Multi-Stage Wind-Resistant Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pivoting shields on hats are inefficient due to single pivot points, causing increased wind resistance and safety issues when lifted, as they project more surface area, leading to less precise movement and potential safety hazards.
Innovation Solution
A pivoting shield assembly with mounting slots, pivot bases, connecting rods, and pathway grooves with elastic locking pieces allows for precise lifting and lowering of the shield through multi-stage adjustments, reducing wind resistance and improving usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shield is pivotally connected at a single pivot point and rotated around the pivot point, then the shield can be lifted freely, but the shield projects from the top of the hat and creates more surface area for wind resistance
Solution Approach 1:
The shield assembly transitions from a single static pivot point to a dynamic multi-point connection system. The shield is connected to both the hat body and the connecting rod, allowing the connection points to move relative to each other as the shield rotates. This dynamic multi-point connection prevents the shield from projecting outward while maintaining lifting freedom.
Solution Approach 2:
The connection system is segmented into multiple connection points: one between the shield and hat body, and another between the shield and connecting rod. This segmentation distributes the rotational movement across multiple points rather than concentrating it at a single pivot, preventing the shield from projecting from the hat top.
2Reliability
If the shield is connected with threaded fasteners at two sides, then the shield is positioned securely, but the lifting and pulling down movement is not precise
Solution Approach 1:
The connecting rod acts as an intermediary component between the shield and the hat body. It transmits the lifting and pulling down movements while maintaining precise control through the pathway groove constraint. This intermediary mechanism provides both secure positioning and precise movement control.
Solution Approach 2:
The connection system transitions from fixed threaded fasteners to a dynamic connecting rod mechanism. The connecting rod can rotate and adjust its position while being guided by the pathway groove, providing both secure attachment and precise controlled movement during shield operation.
3Adaptability or versatility
If the shield is lifted to the top of the hat with single pivot connection, then the shield covers the face completely, but safety issues arise due to increased wind resistance
Solution Approach 1:
The dynamic multi-point connection system allows the shield to achieve full face coverage when lifted while preventing it from projecting outward. The connecting rod and pathway groove mechanism ensures the shield remains constrained to a safe arc of movement, eliminating the safety hazard of wind resistance while maintaining complete protective coverage.

AI summary
A pivoting shield assembly for hats is revealed. The pivoting shield assembly includes mounting slots arranged at two sides of a hat, a pivot base mounted to each mounting slot, a first connecting rod and a second connecting rod each of which having one end pivotally connected to the pivot base and the other end pivotally mounted to a shield, and a pathway groove disposed on an inner side of the first connecting rod. The pivot base includes an elastic locking piece which is mounted and moveable in the pathway groove correspondingly. Thereby lifting up and pulling down of the shield are more precise and having different stages. The pivoting shield assembly for hats is practical.
