Furniture Guide Rail Attachment With Adjustable Contact Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for attaching guide units to furniture lack simplicity and effectiveness in positioning, often resulting in lateral play and instability during movement guidance.
Innovation Solution
A device with adjustable contact sections mounted on a movement rail, allowing independent positioning to align with the rail, and featuring a lower edge design that distributes force evenly and adapts to the rail's shape, ensuring stable and precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple attachment device is used, then the device complexity is reduced, but the positioning precision and stability deteriorate due to lateral play
Solution Approach 1:
The contact sections are made adjustably mounted on the device, allowing their positions to be changed independently of one another. This enables the device to adapt to different movement rail positions and widths, achieving precise positioning without requiring a completely different device design for each application scenario.
Solution Approach 2:
The positions of the contact sections can be adjusted independently to change the geometric parameters of the attachment device. This allows the device to accommodate various movement rail widths and positions by modifying the distance and location of the contact sections, thereby maintaining positioning precision across different applications.
2Device complexity
If fixed contact sections are used, then the device structure is simplified, but the adaptability to different movement rail positions and widths deteriorates
Solution Approach 1:
The contact sections are designed with adjustable mounting mechanisms that allow their positions to be modified independently. This dynamic capability enables the same device structure to adapt to different movement rail positions and widths without requiring multiple specialized devices.
Solution Approach 2:
The attachment device is designed to perform multiple functions by adjusting the contact section positions. A single device can accommodate various movement rail configurations, making it a universal solution that replaces the need for multiple fixed-design devices for different applications.
3Manufacturing precision
If the contact sections are positioned precisely, then the lateral play is reduced, but the adjustment complexity increases
Solution Approach 1:
The adjustment mechanism is segmented into independent contact section adjustments rather than a complex overall repositioning system. Each contact section can be adjusted independently, simplifying the adjustment process while achieving precise positioning to minimize lateral play.
