Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soldering devices face difficulties in removing adhered flux fumes and solidified flux residues from screw shafts and nuts, which hinder the adjustment of conveying rail widths and increase maintenance time and costs.
Innovation Solution
A soldering device with a nut featuring a flange portion and non-meshing parts, such as notches, that allow the screw shaft to rotate and scrape off adhered matter, preventing it from reattaching and facilitating easy adjustment of rail widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the nut and screw shaft are used for adjusting rail width in a soldering device, then the rail width can be adjusted to match substrate size, but flux fumes and solidified residues adhere to the components and prevent smooth rotation
Solution Approach 1:
The patent converts the harmful adhered flux fumes and solidified residues into a beneficial scraping action. By designing the nut with a non-meshing part that creates relative motion against the screw shaft during rotation, the adhered matter is scraped off automatically. The harmful adhesion becomes a useful cleaning mechanism that maintains operational smoothness without requiring separate maintenance interventions.
Solution Approach 2:
The nut structure performs self-cleaning through its own rotational operation. The non-meshing part design ensures that during normal width adjustment rotation, the nut automatically scrapes off flux residues from both itself and the screw shaft. This self-service mechanism eliminates the need for separate cleaning operations and maintains continuous operational capability.
2Ease of operation
If the nut rotates to adjust rail width, then the position can be changed, but adhered flux residues are difficult to remove and increase maintenance time
Solution Approach 1:
The patent transforms the maintenance burden of flux residue removal into a beneficial automatic cleaning function. The non-meshing part design creates relative motion that scrapes off adhered matter during normal operation, converting what would be a maintenance problem into a self-cleaning advantage. This eliminates the need for separate disassembly and cleaning operations.
Solution Approach 2:
The cleaning action occurs continuously during every rotation of the nut for width adjustment. Rather than requiring periodic maintenance stops, the useful action of scraping off residues is integrated into the continuous operational cycle, ensuring the components remain clean and functional without interrupting the adjustment capability.
3Device complexity
If conventional nut and screw shaft are used, then simple structure is maintained, but flux fumes adhere and solidify making movement difficult
Solution Approach 1:
The patent segments the nut structure by introducing a non-meshing part that creates distinct functional zones. The meshing parts continue to provide the primary screw-thread engagement for precise positioning, while the non-meshing part specifically handles the cleaning function through relative motion against the screw shaft. This segmentation allows each part to perform its specialized function effectively.
Solution Approach 2:
The nut is designed with multi-functionality, combining both the traditional positioning function through meshing screw threads and the new cleaning function through the non-meshing part. This universal design allows a single component to perform multiple tasks: precise width adjustment via meshing engagement and automatic self-cleaning via non-meshing relative motion, eliminating the need for separate cleaning mechanisms.

Implementation Method 1

AI summary
Provided are a nut, an attachment for nut and a screw shaft, which are fitted to a coating material coating device or a soldering device and can change a fixed position of the nut easier than that of a convention example even if any adhered matters generated when each device is used for a long time are fixed, and a soldering device using the same. The nut 10 screws on to the screw shaft 2 having a predetermined length. The nut 10 is provided with a non-meshing part 11 composed of a notch 12 that is formed parallel to a movement direction thereof by cutting off screw threads and a flange portion 13, which has connecting holes 14 for connecting another member. Under such a configuration, by forward and/or backward movement of the nut 10, the notch 12 functions as if it scraps the fixed matters 6.
