Webbing Strap Slider Segmentation for Automated Threading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing webbing devices face challenges in automated production due to complex threading processes and loose connections under changing loads, leading to inefficiencies and increased manufacturing costs.
Innovation Solution
The webbing device features a slider with at least two intermediate webs and three strap openings, allowing the webbing to pass through only once, ensuring secure attachment and facilitating automated production by eliminating multiple penetrations and loose ends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple passages of webbing through the slider are used to form the loop, then the webbing device can be adjusted, but the threading process becomes complex and difficult to automate
Solution Approach 1:
The slider is segmented into multiple functional zones with distinct openings: a first opening for webbing passage, a second opening for forming the adjusting loop, and a third opening for additional guidance. This segmentation allows the webbing to pass through each opening only once in a simple linear sequence, eliminating complex threading while maintaining adjustability.
Solution Approach 2:
Instead of having the webbing pass through the same opening multiple times to create the adjusting loop, the invention inverts the approach by providing separate openings for each function. The webbing passes through the first opening, then through the second opening to form the loop, and finally through the third opening, creating a simple one-pass threading sequence that is easily automatable.
2Productivity
If automated production is implemented, then manufacturing efficiency increases, but the threading process must be simplified
Solution Approach 1:
The slider is divided into distinct sections with separate openings for each threading function. This segmentation creates a linear, non-repetitive threading path that can be easily programmed for automated production, significantly improving manufacturing efficiency while maintaining design flexibility.
Solution Approach 2:
The slider is pre-configured with multiple openings positioned to guide the webbing through a predetermined sequence. This preliminary arrangement of openings ensures that during automated production, the webbing follows a fixed, simple path through the slider without requiring complex manipulation or repositioning, enabling efficient automated assembly.
3Adaptability or versatility
If wedge connections are used for reversible attachment, then the webbing can be adjusted, but the connection loosens under alternating loads
Solution Approach 1:
The slider acts as an intermediary device between the webbing and the adjusting mechanism. It provides a stable, rigid structure with multiple openings that guide the webbing through fixed paths, preventing the webbing from shifting or loosening under alternating loads while still allowing for adjustable positioning.
Solution Approach 2:
Instead of using a wedge connection that relies on friction and can loosen, the invention inverts the approach by using a rigid slider structure with predetermined openings. The webbing passes through these fixed openings in a controlled manner, creating a more reliable connection that maintains its position under varying loads while still allowing adjustment.
