Eccentric Adjustment Device for Independent X-Y Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustment devices for vehicle components, such as the gap between headlights and fenders, face challenges in manually setting and minimizing gap size, as they often require coupled movement in X and Y directions, limiting independent control of each point on a plane.
Innovation Solution
The adjustment device decouples the movement of eccentric units, allowing separate displacement in X and Y directions, enabling independent control of each point on a plane by using disk-like guide members with eccentric domes and a tongue and groove connection, ensuring precise adjustment of the movable component relative to the fixed component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two components are adjusted relative to one another using a double eccentric with two eccentric sleeves mounted one inside the other, then adjustment in X and Y directions is achieved, but the movement in X and Y directions is coupled and overlapping, preventing separate movement sequences
Solution Approach 1:
The invention divides the adjustment mechanism into two separate eccentric units, each responsible for one spatial axis. The first eccentric unit (with first eccentric sleeve and first disc-shaped guide member) controls movement in the X direction, while the second eccentric unit (with second eccentric sleeve and second disc-shaped guide member) controls movement in the Y direction. This segmentation eliminates the coupling problem by making each axis independently adjustable through its own eccentric unit, allowing separate movement sequences without interference.
2Ease of manufacture
If eccentric disks are fixedly arranged on an axis, then component displacement is achieved, but a forced coupling in the movement of the component is created
Solution Approach 1:
The invention replaces the single fixed axis with two separate eccentric units that can be independently adjusted. Each eccentric unit has its own adjustment mechanism (first and second adjusting elements) that can be set separately. This eliminates the forced coupling inherent in fixed eccentric arrangements, as each unit's position and movement can be independently controlled without being constrained by the other.
Solution Approach 2:
The invention transforms the static, fixed arrangement of eccentric disks on a single axis into a dynamic system where two eccentric units can be independently positioned and adjusted. The first and second adjusting elements allow the eccentric units to be dynamically set to different positions, enabling flexible control over the displacement of the movable component in both X and Y directions without forced coupling.
3Productivity
If manual adjustment of gap dimension is performed, then assembly is possible, but considerable problems arise in setting and minimizing gap size
Solution Approach 1:
The invention replaces manual adjustment with a mechanical eccentric mechanism that converts rotational movement into precise linear displacement. By rotating the first and second adjusting elements, the eccentric units generate controlled displacement in X and Y directions, enabling precise gap size control without manual measurement and adjustment. This mechanical substitution improves both productivity and manufacturing precision by providing repeatable, controllable adjustment.
Solution Approach 2:
The invention enables precise control of gap dimensions by changing the rotational parameters of the eccentric units. The position and orientation of the first and second eccentric sleeves can be adjusted by rotating them to specific angles, which directly controls the displacement of the movable component. This parameter-based control allows precise gap size minimization and consistency across multiple assembly points.
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
This decoupled movement allows for easier and more precise adjustment of the gap size between vehicle components, ensuring consistency and minimization of the gap across all points on a plane, improving the assembly process by allowing separate control of movements in both spatial axes.
Implementation Method 1
Each of the eccentric units has at least one connecting link for rotatably receiving at least one eccentric element with a disk-like guide element. The disc-like guide member has a dome arranged eccentrically on the disc-like guide member, resulting in the aforementioned eccentric member.
