Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting devices for sliding doors in furniture, such as cupboards, are complex and expensive, requiring precise alignment and often necessitate complex drive systems, making adjustments difficult and prone to readjustment needs.
Innovation Solution
A connecting device comprising a mounting plate, a connecting plate, and a coupling plate, which are connected via screws and flange elements, allowing horizontal, vertical displacement, and limited angular adjustment, enabling easy alignment of sliding doors without the need for complex mechanisms or mutual part detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustable devices with mutually displaceable parts are used, then sliding doors can be adjusted in position, but the devices require complex design and often need to be detached before adjustment
Solution Approach 1:
The connecting device is divided into three separate plates (mounting plate, connecting plate, coupling plate) that can be independently adjusted. Each plate has its own adjusting screw and connecting elements, allowing sequential adjustment without detachment. This segmentation enables complex positioning capabilities while maintaining simple individual components.
Solution Approach 2:
The connecting device incorporates dynamic adjustment capabilities through adjusting screws that allow the plates to be displaced relative to each other in different directions. The first adjusting screw enables displacement in a first direction, the second adjusting screw enables displacement in a second direction, and the third adjusting screw enables angular displacement, creating a dynamically adjustable system.
2Adaptability or versatility
If complex drive devices are used for adjustment, then sliding doors can be adjusted within the carriage device, but the devices become correspondingly expensive
Solution Approach 1:
The adjusting screws directly enable the displacement and positioning of the plates without requiring external drive mechanisms. The system is self-contained, with each adjusting screw providing the necessary mechanical advantage to move the connected plates, eliminating the need for motors, actuators, or complex drive trains.
Solution Approach 2:
The invention extracts the essential adjustment function from complex drive devices and implements it through simple adjusting screws and displaceable plate connections. By removing unnecessary mechanical complexity while retaining the core adjustment capability, the device achieves adaptability at a lower manufacturing cost.
3Reliability
If sliding doors are precisely aligned, then collisions during movement are avoided and aesthetic appearance is improved, but the alignment process becomes time-consuming and complex
Solution Approach 1:
The connecting device is pre-configured with multiple adjustment capabilities built into its structure. The plates are designed with connecting elements and adjusting screws that enable precise positioning to be achieved during installation without requiring subsequent realignment or complex alignment procedures. The adjustment range is built in from the beginning.
Solution Approach 2:
The device allows adjustment of multiple parameters including horizontal position, vertical position, and angular orientation through the three adjusting screws. By enabling changes in these parameters directly at the connecting device, precise alignment is achieved quickly during installation without requiring time-consuming external alignment procedures.
4Manufacturing precision
If adjustable connecting devices are used, then sliding doors can be positioned correctly, but readjustment is often necessary after initial installation
Solution Approach 1:
The connecting device maintains dynamic adjustability through the three adjusting screws even after initial installation. The adjusting screws can be easily accessed and operated to make fine-tuning adjustments to the position and angle of the sliding door, allowing readjustment without detachment or complex procedures.
Solution Approach 2:
The segmented plate design with independent adjusting screws for each degree of freedom allows precise incremental adjustments. Each adjusting screw controls a specific aspect of positioning, enabling fine-tuning of the sliding door position without affecting other parameters, thereby reducing the need for repeated readjustments.
