Soldering Tip Fastening Sleeve with Sector Collar Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional soldering tip mounting systems restrict the use of bent or oversized soldering tips due to manufacturing complexity and high costs associated with grooved fastening sections, limiting design freedom and increasing production costs for wear parts.
Innovation Solution
A soldering tip attachment sleeve with a collar mount on a partial sector of its circumference allows for independent tip design and insertion, eliminating the need for the tip to be guided through the sleeve, and featuring a collar holder that restricts movement, enabling secure attachment with simpler manufacturing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional fastening sleeve is used where the soldering tip must be pushed through it, then the fastening structure is simple, but bent soldering tips or tips with larger diameter cannot be used
Solution Approach 1:
Instead of pushing the soldering tip through the fastening sleeve from the front, the invention inverts the insertion approach by providing a collar mount on the fastening sleeve that receives the collar of the soldering tip. The soldering tip is inserted by guiding its collar onto the fastening sleeve's collar mount, allowing the soldering section to bypass the sleeve entirely. This inverted approach enables bent or oversized tips while maintaining structural simplicity.
2Adaptability or versatility
If grooves are milled in the fastening section of the soldering tip to form a bayonet lock, then angled soldering tips can be used, but manufacturing costs increase significantly
Solution Approach 1:
The invention extracts the complex grooving operation from the soldering tip manufacturing process. Instead of milling grooves in the fastening section of every soldering tip, the bayonet locking features are transferred to the fastening sleeve. The soldering tip only requires a simple collar, which can be manufactured much more economically through processes like turning or bending, eliminating the need for complex groove milling.
Solution Approach 2:
The invention inverts where the complex features are located: rather than putting grooves in the soldering tip, the bayonet locking mechanism is placed on the fastening sleeve. This allows the soldering tip to remain simple while the sleeve absorbs the manufacturing complexity, significantly reducing tip production costs.
3Device complexity
If the soldering tip must be guided through the fastening sleeve, then the fastening structure is simple, but the soldering tip design is constrained by the sleeve dimensions
Solution Approach 1:
The invention inverts the insertion sequence: instead of the soldering tip passing through the fastening sleeve, the collar of the soldering tip is received by the collar mount on the fastening sleeve. The soldering section then engages with the heating element directly without traversing the sleeve. This inversion completely decouples tip design freedom from sleeve dimensions.
