Sliding Door Roller Mechanism With Independent Y/Z Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller mechanisms for sliding doors in vehicles face difficulties in adjusting both the Y and Z axes simultaneously, leading to complex structures, high production costs, and difficult assembly, with no effective solutions for Z-axis adjustment in prior art.
Innovation Solution
A roller mechanism with a compact adjustment mechanism that allows independent adjustments in both the Y and Z axes by using a rotatable axis pin connected to a sandwich bracket, facilitated by a bushing and bearing system, enabling easy and accessible adjustments through a threaded bolt and nut system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex adjustment mechanism is used to enable both Y-axis and Z-axis adjustments, then adjustment capability is improved, but device complexity and production costs increase
Solution Approach 1:
The patent combines Y-axis adjustment (via slot hole in sandwich bracket) and Z-axis adjustment (via rotatable axis pin with bearing) into a single integrated roller mechanism assembly. This merging of adjustment functions into one compact structure reduces overall device complexity while maintaining full adjustability in both axes, directly resolving the contradiction between adjustment capability and structure complexity
Solution Approach 2:
The axis pin serves multiple functions: it acts as a rotational joint for Z-axis adjustment, a mounting element for the sandwich bracket, and a structural connector between the body bracket and sandwich bracket. This multi-functionality eliminates the need for separate adjustment mechanisms, reducing device complexity while preserving comprehensive adjustment capability
2Adaptability or versatility
If a complex adjustment mechanism is used to enable both Y-axis and Z-axis adjustments, then adjustment capability is improved, but production costs increase
Solution Approach 1:
By merging both adjustment functions into a single integrated mechanism using standard components (slot hole, bearing, axis pin, bolt, nut), the patent reduces the total number of parts that need to be manufactured and assembled. This approach lowers production costs while maintaining full adjustment capability in both Y and Z axes
Solution Approach 2:
The adjustment mechanism uses self-contained components where the slot hole provides Y-axis adjustment and the rotatable axis pin with bearing provides Z-axis adjustment without requiring external adjustment devices. This self-service capability eliminates the need for additional expensive adjustment mechanisms, reducing production costs while maintaining versatility
3Adaptability or versatility
If a complex adjustment mechanism is used to enable both Y-axis and Z-axis adjustments, then adjustment capability is improved, but assembly difficulty increases
Solution Approach 1:
The patent segments the adjustment mechanism into distinct functional modules: the slot hole in the sandwich bracket handles Y-axis adjustment, while the rotatable axis pin with bearing handles Z-axis adjustment. This segmentation allows each module to be assembled and adjusted independently, simplifying the overall assembly process while maintaining full adjustment capability
Solution Approach 2:
The axis pin is designed to be rotatable within the bearing, providing dynamic adjustment capability for the Z-axis. This rotational freedom allows the sandwich bracket to be easily positioned and fixed at any height, making assembly straightforward while enabling comprehensive adjustment in both axes
4Adaptability or versatility
If Z-axis adjustment is added to existing Y-axis adjustment mechanism, then adjustment capability is improved, but device complexity increases
Solution Approach 1:
The patent adds Z-axis adjustment by introducing a rotational degree of freedom (another dimension) to the existing Y-axis adjustment mechanism. The rotatable axis pin with bearing enables height adjustment in the Z-dimension while the slot hole maintains Y-axis adjustability, achieving three-dimensional adjustment capability without significantly increasing connection structure complexity
