Modular Ejection Lever Depth Adjustment for Furniture Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture ejection devices require multiple levers with different depths to accommodate various furniture designs, leading to increased manufacturing, deployment, and assembly costs due to varying distances between furniture parts.
Innovation Solution
A modular ejection lever with a removable attachment section that adjusts depth, allowing the same lever to be used for different furniture designs by changing the attachment section, ensuring consistent ejection performance regardless of the type of rear wall material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple ejection levers with different depths are used to accommodate various furniture designs, then the device can be adapted to different furniture configurations, but the manufacturing, deployment, and assembly costs increase
Solution Approach 1:
The ejection lever is divided into two separable parts: a base part and an attachment section. The attachment section can be removed along a separation line, allowing the depth of the ejection lever to be adjusted by removing or retaining the attachment section. This segmentation enables a single base part to serve multiple furniture configurations without requiring multiple complete lever designs.
Solution Approach 2:
The ejection lever design allows dynamic adjustment of its depth dimension through the optional removal of the attachment section. This transforms a static, fixed-depth lever into a dynamically adaptable component that can be reconfigured based on the specific furniture design requirements, resolving the contradiction between adaptability and complexity.
2Manufacturing precision
If multiple ejection levers with different depths are manufactured for different furniture types, then specific furniture configurations can be precisely accommodated, but the manufacturing costs increase
Solution Approach 1:
By segmenting the ejection lever into a base part and an attachment section, the manufacturer produces one standardized base part that can be paired with or without the attachment section depending on the required depth. This reduces the number of unique parts that need to be manufactured with high precision, as the base part design remains consistent across different applications.
Solution Approach 2:
The base part of the ejection lever is designed as a universal component that can function in multiple configurations - with the attachment section for greater depth and without it for reduced depth. This multi-functionality allows a single base part design to serve multiple furniture types, reducing manufacturing costs while maintaining the precision needed for specific depth requirements.
3Reliability
If different depth dimensions of ejection levers are used for different furniture designs, then the ejection function can be optimized for each design, but the assembly processes become more complex
Solution Approach 1:
The separable design with a clear separation line allows the attachment section to be easily added or removed during assembly. This segmentation simplifies the assembly process compared to manufacturing and assembling multiple complete lever variants, as the base part remains constant and only the attachment section needs to be adjusted based on the furniture design.
Solution Approach 2:
The attachment section is pre-designed to attach to the base part in a standardized manner, allowing for quick assembly without complex alignment procedures. This preliminary preparation of the attachment interface enables field assembly and adjustment, making the system easier to install and adapt to different furniture configurations while maintaining reliable ejection function.

AI summary
A device is disclosed for ejecting a furniture part, wherein the device (1) comprises an ejection handle which is mounted on the device and can be driven via a drive unit, and which can be driven out for an ejection process from a start position on the device, such that a bearing section (12, 12') on the ejection handle can be contacted with the furniture part in order to eject the moveably accommodated furniture part in an opening direction. According to the invention, the ejection handle has a projection section (15) which is optionally detachable from the remaining part (17) of the ejection handle along a present separation region, by which means a depth dimension of the ejection handle in the region of the projection section can be preset depending on the presence of the projection section (15) on the ejection handle in such a way that the depth dimension of the ejection handle is reduced, if the projection section (15) is removed, with respect to the depth dimension of the ejection handle if the projection section (15) is not removed.
