Spot Welding Electrode Housing With Swing Lever Dust Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spot welding electrode housing apparatuses are prone to operational failures due to waste and dust accumulation around the electrode withdrawal opening, which is not effectively addressed in existing designs.
Innovation Solution
A lever member is introduced that swings to cover and expose the electrode withdrawal opening, minimizing waste and dust accumulation, and is designed to be housed within the apparatus to prevent immobility and ensure smooth electrode withdrawal and secure stopping of electrodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sliding withdrawal regulating member is used to cover and expose the electrode withdrawal opening, then the electrode withdrawal can be controlled, but waste and dust accumulate around the opening causing operational failures
Solution Approach 1:
The harmful function of the withdrawal regulating member (sliding movement) is extracted and replaced. Instead of using a sliding member that accumulates waste and dust, the patent introduces a lever-shaped member that swings to cover and expose the withdrawal opening, eliminating the harmful accumulation effect while maintaining the controlling function.
Solution Approach 2:
The patent inverts the movement mechanism from linear sliding to rotational swinging. The lever-shaped member swings between a first position (covering the opening) and a second position (exposing the opening), which is the opposite approach of the conventional sliding member, thereby solving the waste and dust accumulation problem.
2Productivity
If the withdrawal regulating member moves frequently to control electrode withdrawal, then electrode replacement efficiency is improved, but operational failures increase due to waste and dust in the moving part
Solution Approach 1:
The harmful sliding movement mechanism is extracted and replaced with a swinging lever mechanism. The lever-shaped member maintains the frequent movement needed for efficient electrode replacement while eliminating the waste and dust accumulation that caused operational failures.
Solution Approach 2:
The patent inverts the movement type from sliding to swinging. This inversion allows the withdrawal regulating member to maintain high-frequency operation for productivity while the swinging motion prevents waste and dust from accumulating in the mechanism, thereby improving reliability.
3Object-affected harmful factors
If the lever member is swung to cover the electrode withdrawal opening, then waste and dust accumulation is minimized, but the structure becomes more complex
Solution Approach 1:
The patent inverts the movement mechanism from sliding to swinging, which solves the waste and dust accumulation problem. The lever-shaped member with its swing axis positioned appropriately achieves the covering and exposing functions through rotational motion, accepting increased structural complexity as a trade-off for eliminating harmful accumulation.
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
The solution reduces operational failures by preventing waste and dust accumulation, ensuring smooth and secure electrode withdrawal, and maintaining the apparatus's aesthetic appeal and structural integrity.
Implementation Method 1
The withdrawal regulating member moves to one side by means of biasing force of a coil spring to cover partially the electrode withdrawal opening
Implementation Method 2
The withdrawal regulating member then moves to the other side against the biasing force of the coil spring to expose the electrode withdrawal opening
Implementation Method 3
a pressing unit is formed on the other end to press one or side by side arranged electrodes housed in the housing passageway toward the one end of the housing passageway by applying spring force

AI summary
In the present disclosure, a housing (4) has a housing passageway (R1) housing a plurality of electrodes (10) linearly therewithin. An electrode withdrawal opening (R2) communicating with the housing passageway (R1) is formed on one end of the housing (4). A pressing unit (5) presses toward one end of the housing passageway (R1) the plurality of electrodes (10) arranged side by side and housed in the housing passageway (R1). A lever member (6) is swung to switch between a state where withdrawal of the electrode (10) from the electrode withdrawal opening (R2) is restrained and a state where the electrode withdrawal opening (R2) is exposed. A regulating coil spring (7) urges and swings the lever member (6) to one side.
