Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional tolerance compensation device is used, then the device can compensate for tolerances between components, but the assembly process becomes complex and difficult to install
Solution Approach 1:
The connecting screw is pre-assembled and held in the positioning element in a delivery state of the device, allowing for simple and quick assembly. The positioning element is configured to hold the connecting screw in a predetermined position before installation, enabling blind assembly without complex alignment procedures.
Solution Approach 2:
The positioning element acts as an intermediary component that holds and positions the connecting screw within the compensation element. This mediator ensures the connecting screw is properly positioned and secured against tilting during assembly, simplifying the overall assembly process while maintaining tolerance compensation capability.
2Manufacturing precision
If the connecting screw is held securely in the positioning element, then positioning accuracy is improved, but the connecting screw must be detachable for assembly
Solution Approach 1:
The positioning element is mounted with a clearance in at least one degree of freedom in an axial through-opening in the compensation element, allowing the connecting screw to be detachably held. This dynamic mounting with clearance enables the connecting screw to be secured against tilting while maintaining the ability to be inserted and removed during assembly.
3Productivity
If blind assembly is enabled, then assembly time is reduced, but the connecting screw must be pre-positioned and detachably held
Solution Approach 1:
The connecting screw is pre-assembled and held in the positioning element in a delivery state of the device. The positioning element is configured to hold the connecting screw in a predetermined position before installation, enabling blind assembly without complex alignment procedures during the assembly process.
Solution Approach 2:
The positioning element serves multiple functions: it holds the connecting screw in a predetermined position, centers the connecting screw in the through-hole, secures the connecting screw against tilting, and allows detachable holding for assembly. This multi-functional design enables blind assembly while managing the complexity through consolidated functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution facilitates easy and rapid installation of the device, ensuring secure and tilt-free positioning of connecting screws, thereby enhancing assembly efficiency and reliability.
Implementation Method 1
the positioning element is mounted with a clearance in at least one degree of freedom in an, in particular axial, through-opening in the compensation element. In addition, the connecting bolt, in particular the connecting screw or the threaded bolt, can be pre-positioned and detachably held in the positioning element, in particular in a delivery state of the device.

AI summary
A device for compensating for tolerances between a first component and a second component that is to be connected, in particular screwed, to this first component by means of a connecting bolt, in particular a connecting screw or a threaded bolt. The device may have a base element, a compensation element in tolerance-compensating engagement with the base element and a positioning element for positioning the connecting bolt in the compensation element. The positioning element is mounted with a clearance in at least one degree of freedom or without clearance in a through-opening in the compensation element.
