Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing alignment devices are used for tool holders and tool disks, then positioning function is provided, but device complexity increases and manufacturing cost rises due to additional positioning aids and complex mechanisms
Solution Approach 1:
The alignment body combines multiple alignment parts (first alignment part with alignment surface and second alignment part with positioning surface) into a single integrated component that attaches to the tool holder. This merging eliminates the need for separate positioning aids while maintaining precise alignment functionality between the tool holder and tool disk.
Solution Approach 2:
The alignment body serves multiple functions simultaneously: it provides alignment surfaces for precise positioning, includes attachment means for securing to the tool holder, and incorporates the positioning surface for interaction with the tool disk. This multi-functionality replaces several separate components with a single versatile alignment device.
2Manufacturing precision
If existing alignment devices with additional positioning aids are used, then positioning precision is maintained, but manufacturing cost increases
Solution Approach 1:
By integrating the alignment parts and positioning surfaces into a single alignment body that attaches to the tool holder, the invention eliminates the need for manufacturing separate positioning aids. This reduces the total number of precision-manufactured components while maintaining the required relative positioning accuracy between tool holder and tool disk.
Solution Approach 2:
The alignment body includes its own attachment means (such as screws or clamps) that allow it to be securely mounted to the tool holder without requiring additional positioning aids. This self-contained design reduces manufacturing complexity and cost while ensuring stable and precise alignment during operation.
3Measurement precision
If complex alignment mechanisms are used, then alignment precision is achieved, but ease of operation decreases
Solution Approach 1:
The alignment body integrates the alignment surfaces and positioning features into a single pre-assembled unit that attaches to the tool holder in one operation. This eliminates the need for operators to manually coordinate multiple separate positioning aids, simplifying the alignment operation while maintaining precision through the integrated design.
Solution Approach 2:
The alignment body is pre-manufactured with precisely positioned alignment surfaces and attachment means already integrated. This preliminary preparation of the alignment device allows for quick and easy installation on the tool holder without requiring complex manual adjustment procedures during operation.

Function Achieved in This Case
Enables precise and cost-effective relative positioning of tool holders to tool disks with a simple, reliable design, reducing the need for additional aids and allowing for easy retrofitting to existing systems.
Implementation Method 1
the groove (38) opens out downwards into a bridge (40) as a connecting web, which extends parallel to the two strip bodies (34, 36) over the entire length of the alignment body (30) and forms a flexible articulation point, via which one strip body (36) can be advanced onto the other strip body (34) with elastic deflection around this bending point
Implementation Method 2
the respective alignment surface (26) of one functional component (10) can be brought into at least partial contact with a positioning surface (28) of the alignment part (24) of the other functional component (12) with a predeterminable alignment force

AI summary
The invention relates to an alignment device for the aligned and detachable fixing of at least one functional component (10), in particular in the form of a tool holder, to a further functional component (12), in particular in the form of a tool disk, around at least one alignment axis (14), wherein the two functional components (10, 12) have in each case at least one contact face (16, 18) for mutual contact with each other. Said alignment device is characterized in that both the one and the further functional component (10, 12) have at least one alignment part (22, 24), in that the respective alignment part (22) of the one functional component (10) is a constituent part of an alignment element (30) and forms an alignment face (26), which can be brought into at least partial contact with a positioning face (28) of the associated alignment part (24) of the further functional component (12) with a predefinable alignment force, and in that the predefinable alignment force is formed by the preload which is produced by a resilient deflection of the part (36) forming the respective alignment face (26) relative to the remaining part (34) of the alignment element (30), taking place as the functional components (10, 12) are fixed to each other.
