Welding Device Casing Partition for Spatter Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric devices, such as welding devices, are at risk of direct exposure to heated spatters or red-hot iron powder through openings during operations, which can damage internal components.
Innovation Solution
The electric device incorporates a casing with strategically positioned intake and exhaust openings, a partition to redirect incoming hot materials, and a radiator with a fan to manage airflow and prevent direct entry of hot spatters into the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If openings are provided on the casing for cooling, then cooling capability is improved, but hot spatters can enter directly into the device
Solution Approach 1:
The opening on the side panel is segmented into two functional parts: an upper intake opening for cool air and a lower exhaust opening for hot air. This segmentation allows the device to maintain cooling capability while preventing hot spatters from entering through the air intake, as spatters naturally fall downward due to gravity and cannot reach the upper intake opening.
Solution Approach 2:
The air intake and exhaust functions are separated in the vertical dimension rather than being positioned adjacent to each other horizontally. By placing the intake opening at the top and exhaust opening at the bottom of the same side panel, the design utilizes the vertical dimension to create a cooling airflow path that is inherently protected from downward-falling spatters.
2Object-affected harmful factors
If louvers are provided in front of openings to prevent spatter entry, then safety is improved, but some red-hot material can still enter at certain spattering angles
Solution Approach 1:
The side panel itself acts as an intermediary barrier between the external environment and the device interior. By positioning the air intake opening at the top of the side panel, the panel structure naturally blocks downward-falling spatters while still allowing cool air to be drawn in, eliminating the need for additional protective components like louvers.
3Productivity
If multiple openings are provided for better cooling, then cooling efficiency is improved, but the risk of spatter entry increases
Solution Approach 1:
Each side panel is segmented to contain both intake and exhaust openings, creating self-contained cooling zones. The air intake opening is positioned at the top while the exhaust opening is at the bottom, ensuring that each opening serves a specific function and that spatters cannot enter through either opening due to their downward trajectory.
Solution Approach 2:
Different regions of the side panel are assigned different functions based on local quality principles: the upper region houses the cool air intake opening while the lower region houses the hot air exhaust opening. This localized functional differentiation optimizes cooling efficiency while inherently protecting against spatter entry at each location.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively prevents hot weld spatters from entering the device, enhancing safety performance by redirecting and cooling internal components while maintaining effective airflow for heat management.
Implementation Method 1
an exhaust opening provided on either the front panel, the right side panel, the left side panel, the rear panel, the top panel or the bottom panel to exhaust internal hot air out of the casing; an intake opening provided on at least one of the panels where the exhaust opening is not provided inside the casing from outside; a fan to exhaust internal hot air out of the casing
Implementation Method 2
a radiator with an enclosure forming a hollow for air-flow and disposed between the partition and the panel on which the exhaust opening is formed so that one open end of the hollow face the exhaust opening

AI summary
An electric device includes: first opening 7 provided on rear panel 4 to exhaust internal air out of casing 1; first partition 12 covering second opening 8 provided on left side panel 2 and having fourth opening 10; second partition 13 covering third opening 9 provided on right side panel 3 and having fifth opening 11; and radiator 14 disposed so as for opening 14C at one end to faceopening 7. The configuration can prevent weld spatters or the like from coming into casing 1 directly.
