Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manually inserting a pintle through interdigitated loops to close seams in papermaking textiles is time-consuming, inexact, and requires prolonged concentration, making it inefficient and labor-intensive.
Innovation Solution
A pintle insertion tool with a drive assembly including a motorized system of rollers and a gear set, powered by a DC power source, which engages a pintle lead wire to drive it through the loops, allowing for efficient and precise seam closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual insertion method is used, then personnel can insert pintle through loops, but the process is time-consuming and labor-intensive
Solution Approach 1:
The patent replaces the manual mechanical insertion process with an automated motorized system. A motor drives a roller that feeds the pintle lead wire through the interdigitated loops, eliminating the need for manual manipulation and significantly reducing insertion time while increasing productivity.
Solution Approach 2:
The automated insertion tool performs the seam closure operation autonomously once positioned. The motorized roller automatically feeds the pintle through the loops without requiring continuous manual intervention, allowing the system to complete the task independently and reduce labor intensity.
2Manufacturing precision
If manual insertion is used, then personnel can close seams, but alignment precision is difficult to achieve
Solution Approach 1:
The patent replaces manual alignment operations with a motorized feeding mechanism that precisely controls the movement of the pintle lead wire. The roller system provides consistent, controlled advancement that ensures accurate alignment with the loops, eliminating the difficulty of manual positioning while achieving high manufacturing precision.
3Productivity
If manual insertion is used, then personnel can install pintles, but prolonged concentration is required
Solution Approach 1:
The patent introduces a motorized roller system to automate the pintle insertion process. While this adds mechanical complexity compared to manual insertion, it eliminates the need for prolonged human concentration and significantly improves productivity. The automated system maintains consistent performance without human fatigue or attention requirements.

AI summary
In one embodiment, a pintle insertion tool is disclosed. The pintle insertion tool includes a housing, and a drive assembly supported by the housing. The drive assembly includes a controller connected to a power supply and configured to drive at least one motor. The drive assembly includes a first roller and a second roller defining at least a portion of a channel therebetween. The at least one motor is configured to rotate the first roller and the second roller in both a forward direction and a reverse direction. The channel is adapted to receive a pintle lead wire such that the pintle lead wire is driven by the first roller and the second roller through interdigitated seam loops on opposing ends of a textile sheet so that a pintle can be pushed into position to complete a seam.
