Quick Crimp Nibs for Strap Binding Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable straps lack interlocking teeth positioned perpendicular to the longitudinal axis, which compromises their tensile strength and efficiency in installation, adjustment, and disengagement.
Innovation Solution
The use of quick crimp nibs with teeth positioned perpendicular to the strap's tensile load vectors, allowing for enhanced binding strength and rapid engagement and disengagement through compression and peeling mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional interlocking straps with teeth are used, then the binding strength is improved, but the installation and adjustment speed remains slow
Solution Approach 1:
The strap transitions from a static interlocking mechanism to a dynamic one where the crimp tab can be compressed to open the nibs for quick insertion, then automatically locks when released. This dynamic behavior enables both strong binding and rapid adjustment.
Solution Approach 2:
The crimp nibs are pre-formed in a compressed state within the crimp tab. When the tab is compressed during installation, the nibs are temporarily opened to receive the opposing strap, then automatically close to lock. This preliminary preparation enables fast engagement without manual manipulation of individual teeth.
2Device complexity
If interlocking teeth are positioned parallel to the longitudinal axis, then the strap structure is simple, but the tensile strength is reduced
Solution Approach 1:
The crimp nibs extend perpendicular to the longitudinal axis of the strap, utilizing a different spatial orientation than traditional parallel teeth. This dimensional change allows the interlocking mechanism to engage in a direction that maximizes resistance to tensile forces while maintaining structural simplicity.
3Ease of manufacture
If traditional knots or Velcro are used, then the strap is easy to manufacture, but the disengagement speed is slow
Solution Approach 1:
The crimp tab functions as a dynamic release mechanism where compression opens the nibs and release allows automatic disengagement. This dynamic behavior enables rapid release without complex tools or procedures, improving speed while maintaining manufacturing simplicity.
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
The solution provides improved tensile strength and faster installation and disengagement of straps compared to traditional methods like Velcro and knots, while maintaining flexibility for easy use.
Implementation Method 1
The toothed, crimp nibs allow for a user to quickly engage the straps by compressing and snapping the teeth together. Users can also quickly disengage the locking mechanism by simply peeling the tabs apart due to their flexible construction.

AI summary
An adjustment strap with quick crimp nibs for a multitude of binding embodiments (such as backpacks, seatbelt fasteners, waist belts, hats etc.) is disclosed. The invention being comprised of two, rigid but slightly flexible, interlocking tabs made of, but not limited to, plastic, silicone compounds and the like. Said interlocking tabs being considered male and female components. Notches along the perimeter of said female tab having a triangular shape with a protruding ridge configured to receive proximally-facing teeth on the male tab. An object of the invention is to enhance the ability of a strap to maintain its interlocking strength during tension loads.
