Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Baseball caps and visors become worn and require frequent appearance changes or repairs, which is costly and difficult with existing methods.
Innovation Solution
A novel edging attachment with adjustable dimensions and patterns that can be easily mounted on the brim using a friction fit mechanism, allowing for customizable designs and repairs by extending over the brim for additional display space and featuring cutting guides for size adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If traditional repair methods are used for worn cap brims, then the cap can be restored, but the process is costly and difficult
Solution Approach 1:
The invention divides the repair process into separate components: a reusable edging attachment that can be independently replaced without replacing the entire cap. This segmentation allows only the worn brim edge to be replaced, reducing cost and complexity compared to traditional full-cap replacement or complex reconstruction methods.
Solution Approach 2:
The edging attachment is designed as an inexpensive, replaceable component that can be easily discarded and replaced when worn. This approach treats the brim edging as a consumable part rather than a permanent fixture, making repair economical and simple by allowing direct replacement of the worn element.
2Reliability
If the edging attachment uses a tight friction fit to secure to the brim, then the attachment is held securely, but it becomes difficult to mount and remove
Solution Approach 1:
The slit in the edging attachment is designed to be flexible and elastic, allowing it to dynamically change shape during mounting. When the brim is inserted, the slit temporarily expands to accommodate it, then contracts to create a secure friction fit. This dynamic behavior enables both easy mounting and secure retention without requiring excessive force.
Solution Approach 2:
The physical parameters of the slit (width, shape) change during the mounting process. The slit is manufactured with dimensions that allow easy insertion of the brim, then through elastic deformation and friction, it transitions to a tighter fit that secures the attachment. This parameter change enables the transition from easy mounting to secure retention.
3Ease of manufacture
If the edging attachment has a standardized size, then it is easy to manufacture, but it cannot accommodate different cap brim sizes
Solution Approach 1:
The edging attachment is designed as a segmented or divisible component that can be cut to different lengths while maintaining its functional integrity. The cutting guide marks indicate where the attachment can be cleanly divided, allowing a single standardized attachment design to be adapted to various brim sizes through simple cutting rather than manufacturing multiple sizes.
Solution Approach 2:
The attachment design allows for dynamic adjustment of its length through cutting. The standardized uncut attachment can be adapted to any brim size by cutting at the appropriate location, providing versatility while maintaining manufacturing simplicity. The elastic nature of the material also allows for some flexibility in fitting different sizes.
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
Enables cost-effective and reliable appearance changes and repairs of baseball caps and visors by providing a secure, customizable edging solution that can be adapted to different sizes and shapes, extending the life of the caps and visors.
Implementation Method 1
This forcibly spreading creates a spring force that holds the edging attachment securely to the brim of the cap or visor.
Implementation Method 2
The edging attachment is shaped so that it is easily mounted on the edge of the brim of a cap or visor and is reliably held thereon by friction fit.

AI summary
An attachment for the edge of an extending brim of a baseball type cap or visor is disclosed which is mounted on the edge of the extending brim to protect or repair the edge. The attachment easily mounts on the brim of a cap or visor and remains securely thereon. The brim is inserted into a slot through the side and along the full length of the attachment. The slot has flared edges that permit the attachment to be easily attached to the brim edge. As the edge attachment is mounted on the edge of a cap or visor the flared edges are deformed outward creating a spring force that firmly holds the edge attachment on the brim. The edge attachment may have an extension that extends over the top of a brim to provide additional space for the display of words, graphics, etc. that are larger than can be displayed on the much narrower front or top edge of the attachment. Barbs on the inside of the edging attachment near the slit bite into the top and bottom of the brim to further assist in holding the attachment on the brim.
