Pouch Attachment Strap with Hook Latch and Loop Retainer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patch attachment ladder system straps lack a secure and efficient mechanism for attaching and detaching accessories from a carrier, such as a vest or fabric panel, due to inadequate engagement and retention systems.
Innovation Solution
A strap design featuring a base panel with a loop retainer and hook latch, along with a terminal extension and notches, provides a dual connection system where the terminal opening upper edge engages the hook latch depression, and the terminal notches interact with the loop retainer, allowing for secure attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple attachment mechanism is used, then ease of operation is improved, but reliability of attachment is worsened
Solution Approach 1:
The attachment mechanism is divided into two independent engagement systems: a hook latch that engages with a terminal opening upper edge, and a loop retainer that engages with terminal notches. This segmentation allows each component to perform its specific function independently, providing secure attachment while maintaining ease of operation through simple snap-fit engagement without complex fastening procedures.
Solution Approach 2:
The attachment mechanism employs self-latching features where the hook latch automatically engages with the terminal opening upper edge and the loop retainer automatically engages with the terminal notches upon insertion. This self-service mechanism eliminates the need for manual fastening or complex operation, providing both ease of operation and reliable attachment through automatic engagement.
2Reliability
If a complex engagement system is used, then reliability of attachment is improved, but device complexity is worsened
Solution Approach 1:
The complex engagement system is segmented into two independent but simple subsystems: a hook latch subsystem and a loop retainer subsystem. Each subsystem uses basic geometric shapes (hook shape, rectangular loop, notch features) that are simple in form but provide reliable engagement when combined. This segmentation maintains device complexity at an acceptable level while achieving secure attachment through the combination of both simple subsystems.
Solution Approach 2:
The hook latch mechanism and loop retainer mechanism are merged into a single integrated attachment system. The hook latch provides primary engagement through the terminal opening upper edge, while the loop retainer provides secondary engagement through the terminal notches. This merging of two simple mechanisms creates a reliable attachment system without requiring either subsystem to be complex on its own.
3Strength
If a rigid connection is used, then strength of attachment is improved, but flexibility of the strap is worsened
Solution Approach 1:
The strap incorporates a flexible base panel with a trench fold that allows the strap to bend and adapt to different configurations. The attachment mechanism uses a loop retainer with a rectangular opening and notches that can accommodate slight variations in positioning, and a hook latch that can engage at different angles. This combination of flexible strap material with geometric engagement features provides both attachment strength and adaptability to different positions and orientations.
Solution Approach 2:
The attachment mechanism transitions from a static rigid connection to a dynamic engagement system where the hook latch can snap into place with rotational movement, and the loop retainer can accommodate positional adjustments. The trench fold in the base panel provides dynamic flexibility, allowing the strap to adapt its shape while maintaining secure attachment through the geometric engagement features that lock into place once positioned.
