Securing device for detachably securing a front panel on a drawer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing securing devices for furniture are hindered by high frictional forces, making them stiff to move and reducing their service life, especially when inserting furniture fittings, leading to unnecessary frictional losses and reduced functionality.
Innovation Solution
A securing device with a coupling mechanism that temporarily couples the movement of the locking device to the catch device only during insertion, utilizing a spring for automatic furniture fitting pull and a pivoting catch and locking lever system, along with an asymmetrical furniture fitting design for optimal support and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking device and catch device are permanently coupled together, then the furniture fitting is securely locked, but frictional losses increase and service life decreases
Solution Approach 1:
The patent applies the dynamics principle by making the coupling between the locking device and catch device temporary rather than permanent. The adjusting contour is designed to provide coupling only during specific phases of operation (insertion and locking), while allowing independent movement during other phases. This dynamic coupling approach reduces unnecessary frictional losses while maintaining secure locking when needed.
2Reliability
If the locking device moves continuously with the catch device, then the fitting is always secured, but wear increases and service life reduces
Solution Approach 1:
The patent implements periodic action by designing the adjusting contour to engage the adjusting body only during specific periods of the operating cycle (during insertion and locking phases). During other periods, the locking device can move independently or remain stationary, reducing wear. The contour's geometry ensures coupling occurs periodically rather than continuously, extending the service life of the components.
3Reliability
If frictional forces are high during movement, then the furniture fitting is held firmly, but insertion becomes difficult and service life reduces
Solution Approach 1:
The patent applies segmentation by dividing the operational phases into distinct segments: insertion phase, locking phase, and operation phase. During the insertion phase, the adjusting contour is designed to minimize frictional forces to ease insertion. During the locking phase, the contour engages to provide firm holding. This segmentation allows optimized friction characteristics for each phase, making insertion easy while maintaining firm holding when required.
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 reduces frictional losses by allowing the catch device to move independently during insertion, enhancing the securing device's functionality and extending its service life by minimizing unnecessary movement and wear, while ensuring secure attachment of the furniture fitting.
Implementation Method 1
the securing device includes at least one spring and the at least one catch device upon insertion of the at least one furniture fitting automatically pulls same towards the drawer by the force of the at least one spring

AI summary
A securing device includes a furniture fitting configured to be premounted on a front panel; a catch device associated with the drawer and configured to receive the furniture fitting and automatically pull the furniture fitting; a locking device configured to prevent the furniture fitting from unintentionally becoming detached from the securing device; and a coupling device for coupling movement of the locking device to movement of the catch device. The coupling device includes an adjusting body and an adjusting contour in or on which the adjusting body is or can be arranged. The adjusting body is arranged on the catch device, and the adjusting contour on the locking device, or vice versa, and the adjusting contour is configured such that the movement of the locking device is initially uncoupled from the movement of the catch device during insertion of the furniture fitting.
