Furniture Guide Carriage Positioning Device for Misalignment Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Guide carriages for furniture parts on guide rails often become misaligned due to distortion or adjustment of the furniture, leading to issues like crooked door leaves and improper closing planes, which existing solutions fail to adequately address.
Innovation Solution
A guide carriage with a positioning device that allows the connecting part to be adjusted in height, lateral, and depth directions relative to the chassis, using a U-shaped carrier with bearing points and a fastening device, enabling active or passive compensation for misalignment through a self-locking connection, such as frictional force, to correct tension and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide carriage is rigidly connected to the furniture part, then the furniture part maintains a fixed position, but any warping or adjustment of the furniture component transfers misalignment to the guide carriage, causing the door leaf to be misaligned in closed position
Solution Approach 1:
The connecting part is designed with adjustable positioning relative to the chassis, allowing dynamic adaptation to furniture distortion. The connecting part can be repositioned in vertical, lateral, and depth directions to compensate for warping of the furniture component, while maintaining reliable connection to the guide carriage.
Solution Approach 2:
The position parameters of the connecting part relative to the chassis are made variable through the positioning device. This allows adjustment of the connecting part's position in multiple directions to compensate for changes in furniture geometry due to warping or thermal expansion, thereby maintaining proper door alignment.
2Ease of manufacture
If the connecting part is fixed to the chassis, then assembly is simple, but the furniture part cannot be adjusted for misalignment or tension
Solution Approach 1:
The connection system is divided into separate functional elements: the chassis, the connecting part, and the positioning device. This segmentation allows the connecting part to be independently adjusted relative to the chassis using the positioning device, while maintaining overall assembly simplicity through modular design.
3Productivity
If the guide carriage uses a simple fastening device, then assembly is quick, but positioning precision of the connecting part relative to the chassis is insufficient for correcting misalignment
Solution Approach 1:
The positioning device acts as an intermediary between the simple fastening device and the connecting part. It provides precise positioning capabilities (vertical, lateral, and depth adjustment) while working together with the quick-fastening mechanism to achieve both assembly speed and positioning accuracy.
