Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a multi-link structure is used to create clearance for attaching and removing the tool, then the clearance requirement is satisfied, but the handling and alignment become difficult
Solution Approach 1:
The pressing tool incorporates surface features that automatically engage with corresponding features on the workpiece, enabling self-alignment during the attaching process. This eliminates the need for manual alignment efforts while maintaining the required clearance for tool attachment and removal.
2Area of stationary object
If the radial pressing tool is designed with multiple links to achieve clearance, then attachment and removal clearance is provided, but operator handling errors increase
Solution Approach 1:
The pressing tool features tactile surface features that provide immediate feedback to the operator through form closure engagement. This feedback mechanism guides the operator to the correct axial working position, preventing handling errors while preserving the clearance needed for tool attachment and removal.
3Area of stationary object
If the pressing tool uses a multi-link structure for mobility, then the required clearance is achieved, but the forming quality may be impaired due to handling errors
Solution Approach 1:
The surface features on the pressing tool automatically align with corresponding features on the workpiece through form closure, ensuring consistent and accurate positioning. This self-alignment mechanism eliminates variability introduced by manual handling, thereby maintaining high forming quality while preserving the clearance necessary for tool attachment and removal.

AI summary
According to the invention, to simplify handling of a multi-membered, movably constructed radial pressing tool, which, when closed, groups multiple matrix elements in a ring to form a drilling matrix and, when open, forms a variable passage gap for a workpiece between two matrix elements, the radial pressing tool, when open, has a number of surface features in the region of the passage gap, and said surface features allow, when the radial pressing tool is pushed onto a workpiece having a collar or bead, creation of a form fit with the collar or bead when the radial pressing tool is in the intended axial working position relative to the workpiece. The radial pressing tool can also comprise a latching device, which is designed to define a latching position which can be overcome in a number of open positions, of which one can be a partially open position in which passage of the workpiece through the passage gap is not possible.
