Welding Face Shield Linkage for Easy Rotating Open-Close Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional facial protection equipment for welding operations requires significant force to rotate the automatic shading part forward, making it difficult to easily open and close, especially after use.
Innovation Solution
A facial protection equipment design featuring a moving bracket slidably coupled to a pivot bracket, with a returning member and magnets providing elastic force and attractive force respectively, allowing for easy front-rear movement and automatic return, facilitated by a free-rotating member reducing friction and enabling easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the fixing band is firmly adhered to the head to fix the automatic shading part, then the stability of the facial protection equipment is improved, but the force required to pull the automatic shading part forward increases significantly
Solution Approach 1:
The connection between the automatic shading part and the fixing band is divided into two stages: a movable connection during operation that allows easy pulling, and a fixed connection during welding that provides stability. The pivot bracket and moving bracket enable the shading part to be pulled forward easily while the fixing band remains firmly attached to the head.
Solution Approach 2:
The connection mechanism transitions from a static fixed connection to a dynamic movable connection. The pivot bracket allows rotational movement, and the moving bracket enables sliding movement, transforming the rigid connection into a flexible one that adapts to different operational states (welding vs. storage/transport).
2Reliability
If the automatic shading part is firmly fixed during welding operations, then the protection effectiveness is improved, but the ease of operation for rotating open and closing deteriorates
Solution Approach 1:
The connection mechanism transitions from a static fixed connection to a dynamic movable connection. The pivot bracket allows rotational movement, and the moving bracket enables sliding movement, transforming the rigid connection into a flexible one that adapts to different operational states (welding vs. storage/transport).
Solution Approach 2:
The pivot bracket and moving bracket act as intermediary mechanisms between the automatic shading part and the fixing band. These intermediaries enable easy rotation and opening/closing operations while maintaining firm fixation during welding through the returning member and magnetic attraction.
3Device complexity
If a simple fixed connection is used between the shading part and head, then the device complexity is reduced, but the ability to easily rotate and reposition deteriorates
Solution Approach 1:
The connection system is segmented into multiple functional components: pivot bracket for rotation, moving bracket for sliding movement, returning member for automatic return, and magnets for positioning. This segmentation allows each component to perform a specific function, achieving easy operation without excessive overall complexity.
Solution Approach 2:
The returning member and magnetic attraction mechanism enable the automatic shading part to return to its original position automatically after being pulled forward. This self-service feature reduces the need for complex manual repositioning mechanisms while improving ease of operation.
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
Enables effortless rotation and closure of the facial protection unit, reducing the force required for operation and ensuring stable repositioning, enhancing user convenience and safety during welding tasks.
Implementation Method 1
a returning member, which is interposed between a pivot bracket and a connection member, and magnets, which are installed on both the pivot bracket and the connection member at one facing side of each other, enable returning movement of a moving bracket to be automatically performed
Implementation Method 2
a returning member, which is interposed between a pivot bracket and a connection member, and magnets, which are installed on both the pivot bracket and the connection member at one facing side of each other, enable returning movement of a moving bracket to be automatically performed
Implementation Method 3
one side of a free-rotating unit that is coupled to one side of a moving bracket in a freely rotatable manner is supported at one side of an inner surface of a pivot bracket such that at least any one side of the moving bracket is separated from the pivot bracket, and thereby a moving operation of the moving bracket can be more easily performed
