Cupboard Pull-Out Front Panel Mounting With Tool-Free Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pull-out devices for tall cupboards require numerous time-consuming tool-related work steps for assembling the front panel, lacking easy and secure mounting options and angular adjustment capabilities.
Innovation Solution
The pull-out device features releasable locking legs for the upper and lower holders, allowing the front panel to be mounted tool-free with pre-assembled holders that can be easily aligned and adjusted via a vertical pivot axis, using an eccentric connection and adjustable screws for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional front panel holders with adjusting screws and fastening screws are used, then the front panel can be securely fixed and aligned, but the assembly process becomes time-consuming and requires multiple tools
Solution Approach 1:
The patent replaces the conventional screw-based mechanical fastening system with a spring-loaded holder mechanism. The holder features a spring element that provides automatic engagement and securing force, eliminating the need for adjusting screws and fastening screws. This mechanical substitution maintains secure fixing while dramatically reducing assembly time and tool requirements.
Solution Approach 2:
The holder is designed to automatically align and secure the front panel without requiring manual adjustment. The spring mechanism self-regulates the engagement force, and the holder automatically positions itself relative to the frame profile, eliminating the need for operator intervention with multiple screws and tools.
2Manufacturing precision
If multiple adjusting screws and fastening screws are used to align and fix the front panel, then precise alignment can be achieved, but the device complexity and number of assembly steps increase
Solution Approach 1:
The patent merges the functions of multiple separate components (adjusting screws, fastening screws, alignment mechanisms) into a single integrated holder assembly. The holder combines securing, aligning, and positioning functions into one component that interacts with the frame profile through a unified mechanical interface, reducing device complexity while maintaining alignment precision.
Solution Approach 2:
The holder is designed as a multi-functional component that simultaneously performs securing, aligning, and positioning tasks. The spring mechanism provides both the securing force and the alignment function, making the holder a universal component that replaces multiple specialized fastening elements.

AI summary
The drawer device (3) comprises a vertical frame (2) with a front plate (4) and a support base (10). The vertical frame is converted from a storage position to a drawing position, where the front plate is fixed at the frame side holding units over an upper holder (5) and a lower holder (6). An upper and lower locking shanks are locked with the holder units in a detaching manner.
