Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fitting arrangements for lift and slide elements often face issues with height adjustment, leading to either grinding or blocking when trying to move the element along the guide rail due to insufficient or excessive stroke of the connecting rod arrangement, resulting in improper positioning and functionality.
Innovation Solution
A fitting arrangement that includes a connecting rod arrangement coupled with an actuating lever and a coupling linkage, utilizing a rotatable eccentric bolt to change the length of the connecting rod, allowing for telescoping and adjustment to ensure proper height adjustment of the lifting device, preventing contact with the upper frame leg and ensuring smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the stroke of the connecting rod arrangement is increased to properly raise the lift and slide element, then the element can be transferred into its raised position, but the element may come into contact with the upper frame leg or the operating lever cannot reach its open position
Solution Approach 1:
The connecting rod arrangement is made adjustable in length through the eccentric bolt mechanism, allowing the stroke to be dynamically adapted to match the specific requirements of different lift and slide elements and frame configurations, thereby preventing contact with the upper frame leg while achieving proper raising
Solution Approach 2:
The length parameter of the connecting rod arrangement is made variable through the eccentric bolt adjustment mechanism, enabling optimization of the stroke to prevent harmful contact with the upper frame leg while achieving the necessary raising height
2Object-affected harmful factors
If the stroke of the connecting rod arrangement is decreased to prevent contact with the upper frame leg, then the element can be safely positioned, but the element cannot be properly raised into its raised position
Solution Approach 1:
The adjustable eccentric bolt mechanism allows the connecting rod arrangement to be dynamically configured with the optimal stroke length, preventing contact with the upper frame leg while achieving sufficient raising height
Solution Approach 2:
The stroke parameter of the connecting rod arrangement is made adjustable through the eccentric bolt, enabling optimization to prevent harmful contact while maintaining adequate raising capability
3Manufacturing precision
If the connecting rod arrangement is made adjustable to optimize height, then proper positioning is achieved, but the device complexity increases
Solution Approach 1:
The eccentric bolt serves as a simple intermediary mechanism that provides adjustable length control for the connecting rod arrangement, achieving precise height positioning without requiring complex adjustment systems
Solution Approach 2:
A single adjustable parameter (the length of the connecting rod arrangement via eccentric bolt) is optimized to achieve precise height positioning, avoiding the need for multiple adjustment parameters or complex control mechanisms

Function Achieved in This Case
The solution allows for precise height adjustment of the lifting device, ensuring the lift and slide element can be properly raised and lowered without obstruction, maintaining functionality and preventing unwanted contact with the frame, thus ensuring smooth operation and optimal positioning.
Implementation Method 1
the push rod is coupled to the coupling linkage via a rotatable eccentric bolt in such a way that its rotation results in a change in length of the connecting rod arrangement

AI summary
The present invention relates to a fitting arrangement for adjusting the height of a lifting device of a lifting-sliding element, which is slidable along a guide rail and can be moved from a lowered position, in which the lifting-sliding element is fixed, to a raised position, in which the lifting-sliding element can be moved. The fitting arrangement comprises a drive rod arrangement for effectively coupling an actuating lever of a lifting-sliding element with a lifting device for raising and lowering the lifting-sliding element.The connecting rod assembly comprises a push rod that can be coupled to the actuating lever in a drive-effective manner and a connecting linkage that can be coupled to the lifting device at least indirectly in a drive-effective manner for connecting the push rod to the lifting device in a drive-effective manner, wherein the push rod is coupled to the connecting linkage via a rotatable eccentric bolt, the rotation of which results in a change in length of the connecting rod assembly.
