Folded Underwear Pad Wing Overturning for Precise High-Speed Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing absorbent pads fail to reliably and precisely fold and couple wings to form a pants-like shape at high production speeds, leading to uncontrollable fluttering and incorrect connections due to the need for wings to be partially folded and overturned.
Innovation Solution
A method involving the folding and overturning of wings on the surface of the pad to maintain them in a stable position for connection, using airflow and mechanical devices to ensure precise alignment and coupling, even at high speeds, utilizing quick connection means like Velcro for adjustable closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If wings are partially folded and overturned to enable connection, then the pad can form a pants-like shape, but the wings experience uncontrollable fluttering at high production speeds leading to incorrect connections
Solution Approach 1:
The wings are preliminarily positioned and stabilized in their overturned state before the connection operation occurs. The suction cups engage the wings early in the process to prevent fluttering during subsequent high-speed transport, ensuring the wings remain in the correct position for reliable connection.
Solution Approach 2:
Suction cups are introduced as an intermediary device to stabilize the wings during the folding and connection process. These suction cups temporarily hold the wings in the correct position, preventing fluttering and ensuring accurate alignment for the Velcro connection mechanism.
2Productivity
If production speed is increased to improve productivity, then more pads can be produced per unit time, but the wings flutter uncontrollably making precise folding and coupling difficult
Solution Approach 1:
Suction cups serve as an intermediary stabilization mechanism that allows high-speed production while maintaining folding precision. By actively holding the wings in position during transport, the system can operate at high speeds without sacrificing the precision needed for accurate wing coupling.
Solution Approach 2:
The patent replaces passive mechanical folding mechanisms with an active suction-based stabilization system. This substitution allows the system to maintain precision at high speeds by using controlled suction forces rather than relying on mechanical constraints that would limit production speed.
3Ease of manufacture
If wings are folded and connected to form pants-like shape during production, then packaging is simplified, but the connection means must be precisely aligned which is difficult at high speeds
Solution Approach 1:
The wings are preliminarily aligned and stabilized using suction cups before the connection operation. This preliminary positioning ensures that when the Velcro connection occurs, the wings are already in the correct alignment, making the connection process reliable even at high production speeds.
Solution Approach 2:
Suction cups act as an intermediary alignment tool, holding the wings in precise position relative to each other during the connection process. This intermediary stabilization ensures accurate alignment of the connection means without requiring complex mechanical alignment mechanisms that would slow production.
