Solution Overview
Problem
Existing soldering tip assemblies for electric soldering devices lack a simple and temperature-resistant solution for interchangeable tips, often leading to overheating and material wastage, and do not provide reliable identification and tracking of the used tip.
Innovation Solution
A soldering tip assembly with a sleeve and holding element that includes stop means for secure attachment, a spring element for displacement control, and a two-dimensional coding for identification, allowing for bayonet-like fastening and preventing overheating, while the stop means and recesses ensure secure and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the soldering tip assembly is designed to be releasably arranged on the handle with a spring element and holding element, then the interchangeability of soldering tips is improved, but the risk of loss and overheating of components increases
Solution Approach 1:
The soldering tip assembly is segmented into distinct components (sleeve, holding element, spring element) that can be independently replaced. The holding element is designed as a separate component that can be lost without damaging the entire assembly, resolving the contradiction by allowing interchangeability while protecting against total loss.
Solution Approach 2:
The sleeve acts as an intermediary component between the handle and the holding element. It provides a protective interface that prevents direct thermal contact between the heating element and the holding element, while still allowing mechanical coupling. This mediator resolves the contradiction by enabling heat transfer to the tip while protecting the holding element from overheating.
2Ease of operation
If the holding element is made as a separate replaceable component, then the ease of replacement is improved, but the temperature resistance and structural integrity worsen
Solution Approach 1:
The system is divided into temperature-exposed components (sleeve, tip) and temperature-sensitive components (holding element). The sleeve acts as a thermal barrier, allowing the holding element to be replaced easily without requiring it to withstand high temperatures, thus resolving the contradiction between ease of replacement and temperature resistance.
Solution Approach 2:
The sleeve serves as a thermal intermediary that blocks direct heat transfer to the holding element. This allows the holding element to be made from materials optimized for mechanical properties rather than temperature resistance, enabling easy replacement while maintaining adequate temperature protection through the sleeve mediator.
3Reliability
If stop means are provided to secure the holding element, then the reliability of attachment is improved, but the device complexity increases
Solution Approach 1:
The stop means are merged with the sleeve structure rather than being separate components. The sleeve integrates both the thermal barrier function and the mechanical stopping function, reducing the total number of parts while maintaining attachment security. This resolves the contradiction by combining functions to reduce complexity.
Solution Approach 2:
The sleeve is designed to perform multiple functions simultaneously: thermal insulation, mechanical coupling, and providing stop means for securing the holding element. This multi-functionality reduces the number of separate components needed, resolving the contradiction between attachment security and device complexity.

AI summary
The invention relates to a soldering tip assembly for an electric soldering device, in particular a soldering iron. The soldering tip assembly is designed to be releasably arranged on a soldering device handle which has a heating element, and the soldering tip assembly has a sleeve with a soldering tip provided on the distal end of the sleeve. The sleeve has an opening at the proximal end for introducing the heating element, wherein a holding element which at least partially surrounds the sleeve in an annular manner and a spring element which is provided between the holding element and the sleeve are provided, the spring element pushing the holding element in the distal direction. The sleeve has at least one stop arranged distally from the spring element. The stop secures the holding element against the soldering tip assembly in the distal direction.
