Eccentric Adjustment Pin for Stable Component Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustment units for relative positioning between fixed and displaceable components fail to adequately account for transverse forces, leading to instability and requiring complex fixation methods, which increases adjustment time and reduces accuracy.
Innovation Solution
An adjustment unit featuring an eccentric head with a circumferential radial contact surface, a shaft with a profiled connecting section, and a sleeve-like receiving part with a resilient annular flange, providing a frictional connection and allowing for rotational angle adjustment, along with a drive mechanism at both ends for flexible access and secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a threaded connection is used to allow axial adjustment, then adjustability is improved, but the holding force is insufficient to withstand lateral loads
Solution Approach 1:
The patent combines axial adjustment capability with radial positioning capability into a single adjustment element. The adjustment element has an adjustment section for axial adjustment and an eccentric section for radial positioning, merging two adjustment functions into one integrated component that can simultaneously provide both adjustability and reliable holding force against lateral loads.
Solution Approach 2:
The patent transitions from single-dimensional axial adjustment to multi-dimensional adjustment by adding radial positioning capability through the eccentric section. This allows adjustment in both axial and radial directions, providing comprehensive positioning control while maintaining structural stability against lateral forces.
2Reliability
If complex fixings are used to maintain position, then stability is improved, but adjustment time increases
Solution Approach 1:
The adjustment element performs self-fixing through its integrated design. The threaded section and eccentric section work together to automatically maintain the adjusted position without requiring additional external fixings or locking mechanisms. The element self-regulates its position through the interaction between its adjustment and eccentric sections.
Solution Approach 2:
The single adjustment element performs multiple functions: axial adjustment, radial positioning, and self-locking. This multi-functional design eliminates the need for separate fixing components, reducing the number of adjustment steps and minimizing adjustment time while ensuring position stability.
3Device complexity
If adjustment is performed from one side only, then device complexity is reduced, but adaptability to closed components is limited
Solution Approach 1:
The adjustment element is designed with universal accessibility by providing drive capability at both ends. The first and second drive elements at opposite ends of the adjustment element allow adjustment operations to be performed from either side, making the device adaptable to both open and closed component configurations without increasing complexity.

AI summary
The invention relates to an adjustment unit (1) for adjusting the relative position between a stationary first component A and a movably mounted second component B, having the following features: an adjustment pin (3) with an eccentric head (10), a cylindrical shaft (30) which comprises a connection section (36), two drive means (14, 46) arranged at the bases, and a sleeve-like receiving part (5), in which the cylindrical shaft (30) of the adjustment pin (3) can be received and which can be adjusted relative to the sleeve-like receiving part (5) via a frictional connection to the connection section (36) in a rotational angle orientation, wherein the eccentric head (10) provides a circumferential radial contact surface (12) against which the second component B can be supported such that a lateral position of the second component B relative to the first component A can be adjusted by rotating the adjustment pin (3) via one of the drive means (14, 46).
