Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hat liners do not provide effective protection against minor head injuries and fail to stabilize hats in an upright position, preventing sagging and easy display.
Innovation Solution
A device that transforms from a flat to a domed shape, with radially extending arms to secure under a hat, offering protection and stability, and can be reused across various hat sizes, including larger ones, while allowing air circulation and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional hat liner is used, then the hat can be worn, but it does not provide effective protection against minor head injuries and fails to stabilize the hat in an upright position
Solution Approach 1:
The device is divided into multiple radially extending arms that can independently flex and adapt. Each arm provides localized protection and stabilization, while collectively forming a comprehensive protective structure under the hat.
Solution Approach 2:
The device transitions from a flat storage orientation to a domed functional orientation dynamically. The radially extending arms are designed to flex and adapt to different hat sizes and head shapes, providing reliable protection without requiring a complex fixed structure.
2Strength
If the device is made rigid to provide protection, then head injury protection improves, but the device cannot be stored flat and becomes difficult to transport
Solution Approach 1:
The device employs dynamic structural transformation, transitioning from a compact flat orientation for storage and transport to a rigid domed orientation for protection. This allows the device to provide strong protective capability when needed while maintaining ease of storage and transport when not in use.
Solution Approach 2:
The device changes its physical parameters (shape, volume, rigidity) based on operational requirements. In flat orientation, it has minimal volume for easy storage; when activated, it transforms into a domed shape with increased rigidity and volume to provide effective head injury protection.
3Reliability
If the device is designed to fit specific hat sizes, then protection effectiveness improves, but it cannot be reused across various hat sizes including larger ones
Solution Approach 1:
The device is designed with universal adaptability to fit various hat sizes through its radially extending arms that can flex and adjust to different curvatures and dimensions. This multi-functional design allows the same device to provide effective protection across small, medium, and large hats without requiring size-specific variants.
Solution Approach 2:
The device adapts its geometric parameters (arm spacing, dome curvature, overall diameter) to match different hat sizes. The radially extending arms can be positioned at various angles and distances from the center, allowing the device to conform to different hat circumferences while maintaining protective effectiveness.
4Stability of the object's composition
If the device includes features for stabilization and protection, then hat stability improves, but the device complexity increases
Solution Approach 1:
The stabilization function is achieved through segmented radially extending arms rather than a single complex structure. Each arm independently contributes to hat stability by engaging with the hat's inner surface, distributing the stabilization function across multiple simple elements rather than one complicated component.
Solution Approach 2:
The device combines multiple functions (protection, stabilization, adaptation) into a single integrated structure. The radially extending arms simultaneously provide impact protection, hat stabilization, and size adaptation without requiring separate components for each function, thereby reducing overall device complexity.

AI summary
A device for providing protection against minor head injury and for stabilizing a hat is provided. The device moves from a generally flat first orientation into a domed-shaped second orientation. In the second orientation, the device is placed under the underside of a hat and supports the hat in an upright position. The device may be placed under a hat for protection and/or to store the hat in an upright position for display and to reduce the sagging of the hat over time. Further, the device may be placed under a hat and the hat worn. The device has a plurality of radially extending arms extending from a center portion. The perimeter surface of the device may be partially inserted within a groove of the hat so as to allow the device to remain secured within the hat. The device is also suitable for providing some protection against head injury when the device is properly worn under a hat.
