Drawer Panel Adjustment Using Rotating Connecting Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer designs with side walls not reaching the upper edge of the panel and rear wall have complex and visually conspicuous mechanisms for adjusting the front panel inclination, which are mechanically intricate and difficult to operate.
Innovation Solution
A simplified mechanism using a connecting element that protrudes less than the drawer panel thickness, with a recess for a removable locking attachment and a threaded bolt for adjustment, allowing the side wall profile section to be connected to the panel and rear wall with accessible and adjustable settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a railing rod with locking projections and a connecting element is used to adjust the front panel inclination, then the panel adjustment function is achieved, but the device becomes mechanically complex and visually conspicuous
Solution Approach 1:
The patent extracts the adjustment function from a complex mechanical system and implements it through a simpler threaded connecting element that integrates directly into the side wall profile section. The connecting element with external threading provides adjustment capability without requiring separate locking projections, railing rods, or cover caps, thereby reducing mechanical complexity while maintaining the panel adjustment function.
2Adaptability or versatility
If a railing rod with a cover cap is used to adjust the front panel inclination, then the panel adjustment function is achieved, but the connecting element becomes visually conspicuous and difficult to operate
Solution Approach 1:
The patent removes the cover cap and railing rod components that obscured the adjusting element. The connecting element with external threading is exposed and directly accessible on the side wall profile section, allowing users to easily operate the adjustment mechanism without having to locate or manipulate hidden components.
3Strength
If the side walls extend to the upper edge of the front panel and rear wall, then the drawer structure is more robust, but the connecting element cannot be accessible for adjustment
Solution Approach 1:
The patent applies local quality by having the side wall profile section terminate below the upper edge of the front panel and rear wall, creating a localized gap that provides access to the connecting element. This localized structural modification maintains overall drawer robustness while enabling adjustment functionality at the specific location where the connecting element is positioned.

AI summary
The invention relates to a drawer having a base panel (10), a screen (11), a rear wall (14) and two lateral walls (12) which are rigidly interconnected. In order for the screen (11) to have its setting on the front side of the drawer readjusted at any time without needing to use expensive and complex fittings between the screen (11) and the end faces of the lateral walls (12): said lateral walls (12) do not reach the upper edges of the screen (11) and rear wall (14); the screen (11) and rear wall (14) are rigidly interconnected in the region of their upper edges using lateral wall profiled sections (13) the ends of which receive connection elements (16 and 15), the connection element (16) associated with the screen (11) being designed as a rotatable connecting pin and supporting a latching projection (24) which can be rotated out of the lateral wall profiled section (13), can latch into a receiving portion in the facing rear side of the screen (11), and determines the angle position of said lateral wall profiled section (13) on the screen (11); and the connection element (15) that faces the rear wall (14) is flush with the end face of the lateral wall profiled section (13) and is provided with protruding latching projections (13.1, 13.2) which can latch into latching receiving portions (14.1, 14.2) on the facing side of the rear wall (14) such that the lateral wall profiled sections (13) can be adjusted in the direction of the screen (11) or of the rear wall (14).
