Drawer Sidewall Locking for Screwless Wall Element Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing drawer arrangements require elaborate mounting processes for wall elements, involving screws or dowels, which increase installation effort and complexity.
Innovation Solution
The furniture fitting is designed to bear against the bearing surface of the wall element, allowing it to be held in place by the locking device of the drawer sidewall, eliminating the need for screws or dowels, and optionally featuring a recess for partial lateral embrace or a snap-connection cover element for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If furniture fittings are fixed to the front panel using screws or dowels, then the mounting is secure, but the installation effort and complexity increase
Solution Approach 1:
The patent extracts the fastening function from the front panel by providing a separate bearing surface on the wall element that interfaces with the furniture fitting. This eliminates the need to attach furniture fittings to the front panel with screws or dowels, as the bearing surface directly receives the furniture fitting which then locks to the drawer sidewall
Solution Approach 2:
The furniture fitting acts as an intermediary component between the wall element and the drawer sidewall. Instead of directly fastening to the front panel, the furniture fitting engages with the bearing surface of the wall element and simultaneously locks to the locking device on the drawer sidewall, simplifying the overall assembly process
2Ease of operation
If furniture fittings are directly locked to the drawer sidewall, then the installation process is simplified, but the securing of the wall element may be compromised
Solution Approach 1:
The solution segments the mounting function into two distinct interfaces: the bearing surface on the wall element for receiving the furniture fitting, and the locking device on the drawer sidewall for securing the furniture fitting. This segmentation allows the wall element to be securely held without requiring direct fastening to the front panel
Solution Approach 2:
The bearing surface is integrally formed on the wall element, allowing the wall element to provide its own mounting interface without requiring separate fastening components. The furniture fitting self-secures by locking to the drawer sidewall while bearing against the wall element's bearing surface
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 the installation process by ensuring secure fixation of the wall element to the drawer sidewall through the locking device, reducing the overall effort required for mounting and allowing for a more compact and secure connection.
Implementation Method 1
a locking lever pre-stressed by at least one spring

AI summary
A drawer arrangement includes a drawer sidewall having a locking device including a locking lever pre-stressed by a spring, and a wall element to be transversely connected to the drawer sidewall. The wall element, in a connected condition with the drawer sidewall, includes a fastening surface facing towards the drawer sidewall, and a bearing surface facing away from the fastening surface. A furniture fitting separate from the wall element connects the wall element to the drawer sidewall, and the furniture fitting is to be releasably locked to the locking lever of the locking device of the drawer sidewall. The furniture fitting, when the wall element is connected with the drawer sidewall, bears at least partially against the bearing surface of the wall element so that the wall element is held on the drawer sidewall by the locking of the furniture fitting with the locking device of the drawer sidewall.
