Solution Overview
Problem
Traditional apparatuses for coupling pour spout fitments to containers are cumbersome, costly, and inefficient, requiring complex rotational and translational movements that increase transverse encumbrance and operational complexity.

A compact apparatus with an oscillating mobile arm and sliding welding head that eliminates the need for rotational elements, allowing for efficient alignment and welding of pour spout fitments directly on one side of the container line, using motorized mechanisms to manage the support and welding head positions for simplified operation and reduced costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional rotational elements and coordinated movements are used, then pour spout fitment coupling can be achieved, but transverse encumbrance and device complexity increase
Solution Approach 1:
The invention extracts and eliminates the rotational element from the traditional apparatus, replacing it with a linear oscillating mobile arm. This removal of the rotational component directly reduces transverse encumbrance while maintaining the core functionality of positioning and welding the pour spout fitment to the container
Solution Approach 2:
Instead of using a rotatable element that rotates supports into position, the invention inverts the approach by using a linearly oscillating mobile arm that brings the support and welding head to the container. This inversion from rotational to linear oscillating motion eliminates the need for transverse space required for rotation
2Productivity
If complex rotational and translational movements are used, then pour spout fitment coupling can be achieved, but device complexity and operational complexity increase
Solution Approach 1:
The invention merges the support for the pour spout fitment and the welding head onto a single mobile arm. This combination allows both components to be positioned and operated simultaneously through a single oscillating mechanism, eliminating the need for separate rotational and translational movements and thereby reducing device complexity while maintaining coupling efficiency
Solution Approach 2:
The mobile arm is designed to oscillate dynamically between a retracted position and a forward position where the support and welding head engage with the container. This dynamic oscillation replaces complex coordinated rotational and translational movements with a single degree of freedom motion, simplifying the mechanism while preserving productivity
