Drawer with a holding device for holding a decorative panel which can be placed onto the side wall of the drawer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for decorative panels in drawers require drilling holes, which can crack the panels and necessitate precise dimension matching, leading to potential wobbling and noise during drawer movement.
Innovation Solution
A clamping device with adjustable holding legs that securely fasten decorative panels without drilling, allowing variable clamping force adjustment to fit different panel dimensions, using metallic legs with surface coatings for enhanced friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drilling holes in the decorative panel for fastening, then the panel can be securely attached to the holding device, but the panel may crack during drilling and become unusable
Solution Approach 1:
The holding device is divided into separate holding legs that can independently clamp the panel edges, eliminating the need for through-holes. The panel remains intact while being securely held by multiple contact points along its edges.
Solution Approach 2:
The holding legs act as intermediaries between the mounting system and the panel. Instead of directly drilling the panel, the holding legs clamp the panel edges and provide attachment points to the drawer structure, protecting the panel from direct mechanical damage.
2Object-affected harmful factors
If using a U-shaped component for holding the decorative panel, then the panel can be fastened without drilling, but the component must be precisely matched to panel dimensions to prevent wobbling and noise
Solution Approach 1:
The holding legs are designed to be adjustable in position and/or angle, allowing dynamic adaptation to different panel dimensions. This adjustability ensures optimal contact and clamping force for each specific panel, preventing play and wobbling without requiring precise pre-matching of fixed components.
Solution Approach 2:
The holding device allows variation in geometric parameters (such as leg spacing, leg angle, or clamping force) to match different panel dimensions. This parameter adjustability ensures stable panel fixation across various sizes while maintaining consistent clamping pressure to eliminate play.
3Device complexity
If using fixed-dimensional holding components, then the device structure is simple, but the device cannot adapt to different panel dimensions and causes play and noise
Solution Approach 1:
The holding legs incorporate adjustment mechanisms that allow users to modify the device's geometric parameters to suit different panel sizes. This dynamic adaptability is achieved through simple mechanical adjustments rather than complex interchangeable components, maintaining relative structural simplicity while enhancing versatility.
4Stability of the object's composition
If increasing clamping force to eliminate play, then panel stability improves, but risk of panel damage increases
Solution Approach 1:
The clamping force is distributed locally at multiple contact points along the panel edges rather than concentrated at single attachment points. This distributed local clamping achieves stable panel fixation while reducing peak stresses that could cause damage.
Solution Approach 2:
The holding legs are designed with features that prevent excessive clamping force, such as built-in stops, elastic elements, or friction-based slip mechanisms. These features cushion against over-clamping before damage can occur, allowing high clamping forces to be applied safely to eliminate play.
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 solution prevents panel cracking and wobbling, ensuring secure and noise-free drawer operation by eliminating the need for panel modifications and allowing optimal clamping force adaptation.
Implementation Method 1
The surface of the holding legs intended for contact with the decorative panel can be provided with a surface coating, which increases the static friction and enables the holding legs to engage smoothly with the decorative panel.
