Cap Multi-Point Locking Strap Interior Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cap size adjustment mechanisms using interlocking plastic straps cause user discomfort and an unappealing appearance due to protruding ridges and visible holes, respectively.
Innovation Solution
A cap size adjustment mechanism utilizing two fixed multi-point locking straps attached to the sweatband and a removable strap with protrusions and holes, allowing for adjustable cap size without visible straps, providing a smooth and customizable surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If interlocking plastic straps are used to adjust cap size, then cap size adjustment is achieved, but user comfort deteriorates due to protruding ridges
Solution Approach 1:
The invention extracts and removes the problematic interlocking plastic strap mechanism from the visible exterior of the cap. The adjustable strap system is relocated to the interior, specifically attached to the sweatband, so that only a smooth flat surface is visible on the outside. This extraction eliminates the protruding ridge that causes discomfort while preserving the cap size adjustment functionality through the interior-mounted adjustable strap.
2Adaptability or versatility
If interlocking plastic straps are used to adjust cap size, then cap size adjustment is achieved, but appearance quality deteriorates due to visible holes and cluttered appearance
Solution Approach 1:
The invention extracts the visible elements of the adjustment mechanism (holes, overlapping straps, and cluttered components) from the exterior surface. The adjustable strap and its attachment points are positioned on the interior of the cap, attached to the sweatband, so that the exterior maintains a clean, smooth appearance without visible holes or mechanical components.
Solution Approach 2:
The invention transitions the adjustment mechanism from a two-dimensional exterior surface arrangement to a three-dimensional interior configuration. By moving the strap system into the interior space of the cap and attaching it to the sweatband, the mechanism operates in a different spatial dimension that does not interfere with the exterior aesthetic qualities.
3Ease of operation
If traditional adjustment mechanisms are used, then cap size can be changed, but the mechanism causes irritation and discomfort
Solution Approach 1:
The invention introduces the sweatband as an intermediary element that mediates between the adjustment mechanism and the user's head. The adjustable strap is attached to the sweatband rather than directly to the cap structure, allowing the sweatband to absorb and distribute any pressure or movement. This intermediary placement ensures that adjustment operations do not create direct contact points that would cause irritation to the user.

AI summary
The present invention is used to adjust the size of a cap that has approximately half-circle of no cap material in the rear of the cap. There are two fixed multi-point locking straps and each is attached to the inside of the sweatband on each side of the approximately half circle of no cap material. There is one removable multi-point locking strap across the space between the sides of the half-circle of no cap material in the rear of the cap. The ends of the removable strap are attached to the fixed straps by inserting one or more protrusions into one or more holes. In one embodiment, the fixed straps are male multi-point locking straps with protrusions and the removable strap is a female multi-point locking strap with holes. In another embodiment, the fixed straps are female multi-point locking straps with holes and the removable strap is a male multi-point locking strap with protrusions.
