Underwear Pad Wing Folding With Airflow-Stabilized Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing production methods for absorbent pads fail to reliably and precisely fold and couple wings to form a stable pants-like shape at high production speeds due to uncontrollable fluttering of wings during processing, leading to inconsistent coupling.
Innovation Solution
An apparatus with folding means that overturn and maintain wings in a stable position on the pad surface, using airflow and fingers or suction to ensure precise coupling of wings, even at high speeds, forming a reliable pants-like shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high production speeds are used in pad manufacturing, then productivity increases, but the wings become uncontrollable and flutter during processing, leading to imprecise folding and coupling
Solution Approach 1:
The apparatus performs preliminary actions by first lifting the wings with airflow before folding them with fingers. This sequence ensures wings are controlled and positioned correctly before the folding operation, preventing fluttering even at high production speeds while maintaining precise coupling.
Solution Approach 2:
The patent uses pneumatic systems (airflow generators) to lift and control the wings during processing. This pneumatic control stabilizes the wings before folding operations, eliminating uncontrollable fluttering and enabling precise coupling at high production speeds.
2Adaptability or versatility
If wings are folded and coupled to form pants-like shape, then product functionality improves, but the process becomes unreliable at high speeds due to wing fluttering
Solution Approach 1:
Pneumatic airflow is used to lift and stabilize wings before folding, providing reliable control throughout the coupling process. This ensures consistent and reliable pants-like shape formation even at high production speeds where traditional mechanical control would fail.
Solution Approach 2:
The patent replaces purely mechanical folding systems with a combined pneumatic-mechanical system. Airflow lifting precedes mechanical finger folding, creating a more reliable process that maintains coupling accuracy at high speeds where traditional mechanical systems would experience fluttering and inconsistency.
3Device complexity
If traditional folding methods are used without wing control, then device complexity is reduced, but manufacturing precision and reliability deteriorate due to uncontrollable wing movement
Solution Approach 1:
The addition of pneumatic airflow generation creates a relatively simple control mechanism that efficiently lifts and stabilizes wings before folding. This pneumatic control system achieves precise wing positioning and reliable coupling without requiring complex mechanical control mechanisms.
Solution Approach 2:
Airflow acts as an intermediary between the wing and the folding fingers. This intermediate pneumatic control step stabilizes the wing, making it ready for precise folding and coupling without requiring the folding mechanism itself to be overly complex.

AI summary
A method for folding pads shaped as pants includes overturning a first wing and a second wing provided with a hook and loop connection by 180° on a plane of the pad and maintaining the first wing and the second wing in that position until the pad shaped as pants is closed.
