Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for fixing a connecting head on an electrode casted in a mold are time-consuming and costly, requiring multiple manipulations and precise dimensions, which limits recycling and increases operating time and expenses.
Innovation Solution
A tool with a longitudinally adjustable mechanism for immobilizing the connecting head, allowing it to be fixed in multiple positions along the longitudinal axis, combined with a radial immobilization mechanism, enabling the connecting head to be securely attached without intermediate welding or mechanical assembly during the electrode's formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connecting head is fixed using traditional methods (sawing dovetail then welding), then the connecting head can be securely attached to the electrode, but the process becomes time-consuming and requires multiple tedious manipulations
Solution Approach 1:
The mounting member is pre-positioned inside the mold base during electrode formation, and the connecting head is mechanically assembled to it while still in the mold. This preliminary positioning eliminates the need for subsequent welding operations and complex manipulations, significantly reducing operating time while maintaining secure attachment.
Solution Approach 2:
The invention combines the mounting member integration and connecting head attachment into a single operational phase (during electrode formation in the mold). By merging these steps and performing them concurrently rather than sequentially, the process eliminates multiple separate manipulations and reduces total operating time.
2Manufacturing precision
If the mounting member dimensions are precisely matched to the mold cavity shape, then the connecting head can be properly positioned, but the mounting members cannot be recycled and costs increase
Solution Approach 1:
The mounting member is designed with a standardized interface that fits within the mold base cavity, allowing the same mounting member to be used across multiple electrodes and mold configurations. This universal design enables recycling of mounting members while maintaining precise positioning through the standardized mechanical interface.
Solution Approach 2:
The system is segmented into modular components: the mold base with its cavity, the reusable mounting member with standardized dimensions, and the connecting head. This segmentation allows the mounting member to be detached and reused in different applications while the mold base remains stationary, achieving both precision and recyclability.
3Reliability
If multiple manipulations are required to fix the connecting head, then secure attachment is achieved, but the process complexity and costs increase
Solution Approach 1:
The mounting member is pre-installed in the mold base during electrode formation, and the connecting head is mechanically assembled to it in a single straightforward operation. This preliminary setup eliminates the need for subsequent welding, sawing, or other complex manipulations, reducing process complexity while maintaining attachment security through the mechanical assembly design.

AI summary
The tool according to the invention comprises a connecting head (22) support (70) extending along a longitudinal axis (B-B′); a mold base (72), supported by the support (70), the mold base (72) defining an axial orifice for passage of the connecting head (22); an end-piece (74) for mounting the support (70) on a movement member for moving the tool in the mold; and a mechanism (76) for longitudinal immobilization of the connecting head (22) on the support (70). The mechanism (76) for longitudinal immobilization is longitudinally adjustable relative to the support (70) in order to immobilize the connecting head (22) relative to the support (70) in at least two different longitudinal positions along the longitudinal axis (B-B′).
