Solution Overview

Problem

In the field of shielded metal arc welding, welding rod dryers require preheating before use, leading to significant time delays and inconvenience, especially in heavy industry settings where multiple operators need to access preheated dryers simultaneously, and the process of storing and retrieving dryers is complex and inefficient.

Innovation Solution

A dispensing device with multiple chambers that can maintain welding rod dryers at a predetermined temperature, allowing simultaneous and convenient dispensing without separate storage, featuring power supply connections adaptable to different terminal shapes, timers for preheating, sensors for state monitoring, and a locking mechanism for safety, enabling rapid and efficient access to preheated dryers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If welding rod dryers are stored separately in a drying oven and then transferred to portable dryers, then the welding rods can be dried and stored properly, but significant time is wasted and the process becomes complex and inconvenient

Engineering Contradiction:
Improvewelding rod drying qualityVSAvoidtime for drying and transferring
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent combines the storage function and drying function into a single integrated chamber. The welding rod dryer includes both a storage chamber for keeping welding rods and a drying chamber for heating, eliminating the need for separate drying ovens and transfer operations. This merging of functions directly resolves the time loss and procedural complexity while maintaining reliable drying quality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system performs preliminary drying and heating actions within the integrated chamber before the welding rod is actually needed. The storage chamber maintains welding rods in a ready state, and the drying chamber can preheat and dry rods in advance, so that when needed, the drying process is already complete or nearly complete, minimizing waiting time and eliminating transfer operations.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If multiple welding operators need to access preheated dryers simultaneously, then welding operations can proceed in parallel, but the process becomes inefficient and requires significant coordination

Engineering Contradiction:
Improvesimultaneous welding operationsVSAvoidcoordination and access management
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the drying system into multiple independent chambers, each capable of operating autonomously. Each chamber can store and dry welding rods independently, allowing multiple operators to access different chambers simultaneously without coordination overhead. This segmentation of the drying system into parallel independent units directly enables simultaneous welding operations while eliminating complex access management.

Inventive Principle:
Principle #1Segmentation

3Volume of stationary object

If welding rod dryers are stored in a typical shelf, then space is utilized efficiently, but heavy industry fields experience significant delay time when operators need to select and receive dryers

Engineering Contradiction:
Improvestorage space utilizationVSAvoidtime to select and receive dryer
Core Design Contradiction:
Volume of stationary objectVSLoss of time

Solution Approach 1:

The patent merges the storage chamber and drying chamber into a single integrated unit. Welding rods are stored in the storage chamber and can be dried in the drying chamber without being removed or transferred. This eliminates the time-consuming process of selecting and receiving dryers from separate storage shelves, as everything is contained within one integrated system that maintains ready-to-use welding rods.

Inventive Principle:
Principle #5Merging (Combining)
