Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a turret-type positioning device with multiple sections is used, then adaptability to different types and sizes of connecting elements is improved, but the axial positioning becomes complicated and error-prone
Solution Approach 1:
The positioning device is segmented into multiple independent positioning elements (first positioning element, second positioning element, etc.) arranged circumferentially on the carrying head. Each positioning element can be independently selected and axially adjusted, allowing adaptation to different connecting element types and sizes without complicating the overall positioning mechanism. This segmentation enables simple axial adjustment of individual elements rather than complex multi-position turret shifting.
Solution Approach 2:
The carrying head is designed to be rotatable relative to the crimping tool, allowing dynamic selection of different positioning elements by rotation. The positioning elements can be axially adjusted dynamically to different positions along the axial direction, enabling flexible adaptation to various connecting element requirements without fixed, complicated positioning structures.
2Manufacturing precision
If a turret with multiple axial positions is used, then positioning accuracy for different element sizes is improved, but the operation becomes cumbersome and error-prone
Solution Approach 1:
Multiple positioning elements are pre-installed on the carrying head in different circumferential positions, each capable of axial adjustment. The desired positioning element can be selected in advance by rotating the carrying head to the appropriate angular position, then that specific element is axially adjusted to the required position. This preliminary arrangement of multiple elements eliminates the need for complex multi-step axial positioning operations.
Solution Approach 2:
The positioning system uses two independent dimensions: angular position (rotation of carrying head) and axial position (adjustment of positioning elements). By separating the selection function (angular dimension) from the positioning function (axial dimension), the system achieves high positioning accuracy while maintaining simple, intuitive operation. The user rotates to select the element type, then adjusts the axial position independently, avoiding cumbersome multi-position turret operations.
3Manufacturing precision
If the positioning element is moved axially close to the crimping tool, then positioning precision for short connecting elements is improved, but the risk of interference with the crimping tool increases
Solution Approach 1:
The positioning element's axial position is dynamically adjustable rather than fixed. The element can be moved axially closer to the crimping tool when precise positioning of short connecting elements is required, and moved away when interference risk increases. This dynamic adjustability allows optimal positioning for each specific crimping task, balancing precision requirements with interference avoidance.
Solution Approach 2:
The positioning function is separated into independent positioning elements that can be individually adjusted axially. Only the selected positioning element needs to be close to the crimping tool for precise positioning, while other elements remain in their initial positions. This segmentation minimizes the risk of interference, as only one element is positioned close at a time, and it can be retracted if interference occurs.

AI summary
The invention relates to a positioning device for crimping tools. Such positioning devices are suitable for the positioning of an element that is to be pressed relative to the pressing elements of the crimping tool, which are formed by notching elements, crimping plungers or the like. According to the invention, the positioning device (Ol) comprises a support head (03) which is rotatable with respect to the crimping tool (02, 23). A plurality of positioning elements (11, 12) are peripherally arranged in said support head and can be individually displaced in an axial manner in the direction of the crimping tool (02, 23) between an initital position and a working position. The invention also relates to a crimping tool, for example a crimping pliers or a crimping insert for a crimping machine.
