Furniture Lid Fitting Lateral Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lid fitting technologies for furniture lack a simple and efficient mechanism for lateral adjustment, often requiring complex mechanisms and large adjustment paths, which can lead to increased complexity and size of components.
Innovation Solution
The method involves using two lid fittings arranged on opposite sides of the lid, with adjustable elements between the base elements and swivel arms, allowing for lateral bracing and adjustment by screwing mechanisms, utilizing materials like polyamide and polyoxymethylene for low friction, and incorporating a head section with a countersunk hole to prevent over-screwing, enabling small adjustment paths for large leverage effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex adjustment mechanisms are used to achieve lateral adjustment of the lid, then the adjustment precision is improved, but the device complexity increases
Solution Approach 1:
The adjustment mechanism is segmented into two independent lid fittings, each with its own adjustment element. By dividing the adjustment function across two symmetrically arranged fittings, the system achieves precise lateral control without requiring a single complex adjustment mechanism. Each fitting independently contributes to the overall lateral positioning of the lid.
Solution Approach 2:
Instead of using a complex mechanism to directly achieve lateral adjustment, the patent inverts the approach by using the vertical positioning of adjustment elements to control lateral movement. The adjustment elements are positioned vertically on the lid fittings, and their vertical adjustment translates into lateral bracing and positioning of the lid through the geometry of the fitting mechanism.
2Adaptability or versatility
If large adjustment paths are used to achieve lateral movement of the lid, then the adjustment range is improved, but the component size increases
Solution Approach 1:
The patent transitions the adjustment movement from a horizontal lateral path to a vertical adjustment path. The adjustment elements move vertically on the lid fittings, and this vertical movement is converted into lateral bracing and positioning of the lid. This dimensional transformation allows for adequate adjustment range without requiring large horizontal component dimensions.
Solution Approach 2:
The patent changes the adjustment parameter from lateral displacement to vertical position. By adjusting the vertical position of the adjustment elements on the lid fittings, the system achieves lateral bracing and positioning effects. This parameter change allows compact component design while maintaining effective adjustment capability.
3Speed
If friction torque is applied over the entire pivoting travel to control lid speed, then the lid opening speed control is improved, but the energy loss increases
Solution Approach 1:
Instead of applying friction torque throughout the entire pivoting travel, the patent applies friction control only at specific critical points - namely at the adjustment elements where lateral bracing occurs. This partial application of friction is sufficient to control lid opening speed and prevent dangerous rapid movement, while minimizing unnecessary energy loss during the rest of the pivoting motion.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies lateral adjustment of furniture lids by eliminating lateral play, reducing component complexity, and achieving a large adjustment path with minimal movement, ensuring stability and ease of use while preventing unintentional unscrewing.
Implementation Method 1
utilizing materials like polyamide and polyoxymethylene for low friction
Implementation Method 2
The adjustment elements are adjusted transversely to the respective swivel plane. In a specific embodiment, the adjustment elements each have a threaded section that is screwed into a thread of the swivel arm
Implementation Method 3
the elements for connecting the lid to the lid fitting can be made smaller and less complex. Furthermore, the lever action of the swivel arm allows for greater adjustment of the lid due to very small adjustment travel of the adjustment element
