Drawer Guide Coupling with Spring Pressing for Precise Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for adjusting the position of furniture pull-outs relative to guide units in furniture bodies suffer from play in the height direction, which hinders precise adjustment and reliability.
Innovation Solution
A device with a coupling member made of plastic and integrally formed pressing means, allowing for relative mobility in the height direction and featuring a side adjustment unit with an actuating element and coupling member for lateral adjustment, along with a height adjustment unit using a wedge-shaped ramp, enables precise adjustment of the furniture pull-out's position without hindering the adjustment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional adjusting devices are used to adjust the position of furniture pull-out relative to guide unit, then adjustment functionality is provided, but play in height direction occurs which hinders reliable and precise adjustment
Solution Approach 1:
The pressing means are designed with resilient properties allowing dynamic adaptation. The resilient pressing means can be overpressed during height adjustment to eliminate play, then maintain continuous contact to secure the adjusted position, providing both adjustment freedom and position security.
Solution Approach 2:
The pressing force parameter is made variable through the resilient design. During adjustment, the pressing means can be overpressed to change the contact state and eliminate play, then return to normal pressing force to maintain the adjusted position without creating permanent constraints.
2Stability of the object's composition
If pressing means are used to connect device to guide unit, then connection stability is improved, but adjustment process may be hindered if pressing is too strong
Solution Approach 1:
The resilient pressing means provide dynamic connection stability. During adjustment operations, the resilient design allows temporary overpressing to overcome resistance and eliminate play, while maintaining stable connection throughout the adjustment process without permanent loss of ease of operation.
Solution Approach 2:
The resilient pressing means act as a cushioning element that anticipates adjustment needs. The resilient properties allow the pressing means to be temporarily overpressed during adjustment without causing damage or permanent deformation, providing a buffer that facilitates easy adjustment while maintaining stable connection.
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
The device reduces inconvenient play in the furniture pull-out guide unit system, allowing for reliable and precise height and lateral adjustments, ensuring uniform gap widths and joint patterns.
Implementation Method 1
the pressing means have at least one spring element (71) which projects away from the coupling member (28) and is supported on the support surface of the guide unit when the device (11) is in use
Implementation Method 2
The pressing means are resiliently pretensioned
