Solution Overview

Problem

The existing methods for assembling a front panel on a drawer, which consists of a decorative panel and a frame, are not efficient, particularly when the decorative panel needs to be mounted or replaced after the frame is already locked to the drawer side wall.

Innovation Solution

A separate holding device, such as a snap connection, is used to connect the decorative panel to the frame, allowing for easy assembly and disassembly, even when the frame is already locked to the drawer side wall, by being arranged on the rear side of the panel and providing a visually unobtrusive solution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the decorative panel is directly integrated with the frame, then the structure is simple, but the decorative panel cannot be easily replaced after assembly

Engineering Contradiction:
Improvereplaceability of decorative panelVSAvoidstructure complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The front panel assembly is divided into separate components: the frame, the decorative panel, and intermediate holding devices. This segmentation allows the decorative panel to be independently removed and replaced without affecting the frame structure, while maintaining a relatively simple overall design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Holding devices are introduced as intermediary elements between the frame and the decorative panel. These holding devices facilitate the connection and disconnection of the decorative panel, enabling easy replacement while keeping the frame and panel designs simple.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the holding device is integrated into the decorative panel or frame, then the structure is compact, but the assembly process becomes more complex

Engineering Contradiction:
Improveassembly easeVSAvoidnumber of separate components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The holding device is designed as a separate, independent component rather than being integrated into the frame or decorative panel. This segmentation simplifies the assembly process, as the holding device can be independently manufactured and then easily attached to connect the frame and panel.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The holding device is designed to be self-contained with its own locking mechanism (such as a snap connection), allowing it to securely hold the decorative panel without requiring additional fasteners or complex assembly steps. The holding device essentially serves itself to create a secure connection.

Inventive Principle:
Principle #25Self-service

3Reliability

If the locking mechanism is visible from the front, then the locking function is clear, but the aesthetic appearance is compromised

Engineering Contradiction:
Improvelocking reliabilityVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The locking function is extracted from the visible front area and relocated to the rear side of the decorative panel. The holding device with its locking mechanism is positioned on the rear side, so the locking function remains reliable and functional while being hidden from the front view, thus preserving the aesthetic appearance.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The locking mechanism is moved from the front dimension (visible area) to the rear dimension (hidden area). By relocating the holding device to the rear side of the decorative panel, the locking function operates in a different spatial dimension that does not interfere with the aesthetic appearance of the front surface.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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 method enables convenient and problem-free assembly, disassembly, and replacement of the decorative panel without requiring tools, ensuring a secure and aesthetically pleasing connection.

Implementation Method 1

the holding device can be positively connected to the frame by elastic bending or deformation and subsequent springing back of at least one locking element

Methodology Applied
Scientific EffectElastic bending: Elasticity

AI summary

The invention relates to a front panel (7) for a drawer (4), wherein: the front panel (7) is formed by at least one decorative plate (10) and a frame (5) for holding the decorative plate (10); at least some regions of the decorative plate (10) are held inside the frame (5) when in a mounted state, and the frame (5) has at least one locking part (14a, 14b) for releasably locking the front panel (7) to a drawer side wall (9); at least one retaining device (16a, 16b), which is separate from the decorative plate (10) and the frame (5), is situated on at least one end region of the decorative plate (10) to hold the at least one end region of the decorative plate (10); and the separate retaining device (16a, 16b) can be connected releasably to the frame (5).
