Adaptor Plate Guides for Precise Furniture Ejector Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning devices for ejection mechanisms in furniture require complex measurement and assembly processes, leading to potential errors and limited adjustability for different drawer lengths and materials, especially when dealing with varying rear wall thicknesses and guide systems.
Innovation Solution
The use of an adaptor plate with multiple guides allows for adjustable positioning of the ejection device relative to the furniture carcass, enabling precise placement regardless of the drawer material or guide system, with options for different depth positions to accommodate various rear wall thicknesses and ensure proper ejection and touch-latch functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a first fixing device is fixed to the floor of the carcass and a second fixing device is fixed to the rear wall of the carcass with a carrier rail between them, then adjustment in the depthwise direction can be effected, but the assembly complication and expenditure increases significantly
Solution Approach 1:
The positioning function is segmented into two independent parts: the adaptor plate provides depth adjustment through multiple guides, while the carrier rail handles lateral positioning. This segmentation allows each component to perform its specific function without requiring complex assembly of multiple fixing devices.
Solution Approach 2:
The depth adjustment function is extracted from the complex two-fixing-device system and incorporated into the adaptor plate as an integral component. This eliminates the need for separate depth adjustment mechanisms and reduces assembly complexity while maintaining adjustability.
2Reliability
If the ejection lever is spaced excessively far from the rear wall of the drawer, then the ejection lever cannot deploy its full ejection action, but precise positioning requirements increase measurement and assembly complication
Solution Approach 1:
The adaptor plate is pre-configured with multiple guides at specific depth positions during manufacturing. This preliminary action ensures that the correct guide is already in place for the required ejection distance, eliminating the need for complex measurements and adjustments during assembly while guaranteeing proper ejection lever positioning.
Solution Approach 2:
The invention provides discrete depth position options through multiple guides on the adaptor plate, allowing selection of the appropriate guide based on the specific ejection requirements. This changes the positioning parameter from a continuous adjustment requiring precise measurement to a discrete selection from pre-defined positions.
3Reliability
If the ejection lever does not bear centrally against the rear wall of the drawer, then the drawer can tilt upon being ejected, but positioning precision requirements increase assembly expenditure
Solution Approach 1:
The adaptor plate incorporates transverse guides that are pre-positioned to ensure central alignment of the ejection device with the drawer rear wall. This preliminary positioning action during manufacturing eliminates the need for complex alignment procedures during assembly, ensuring the ejection lever bears centrally against the drawer for stable ejection.
4Adaptability or versatility
If multiple fixing devices and carrier rails are used for positioning, then adjustment range can be achieved, but the time and resources required for measurement and fixing increase
Solution Approach 1:
The adaptor plate merges the functions of multiple fixing devices into a single integrated component. It combines the mounting plate for attaching to the carcass with multiple guides for depth adjustment and transverse guides for lateral positioning, all in one piece. This merging dramatically reduces assembly time and resource requirements while maintaining full positioning capability.
Solution Approach 2:
The adaptor plate is designed as a universal component that can accommodate different ejection device positions and configurations through its multiple guides. It serves multiple functions: mounting the ejection device, providing depth adjustment, ensuring transverse alignment, and adapting to different drawer types, all through a single component rather than multiple specialized fixtures.

AI summary
A positioning device positions an ejection device for ejecting a movably mounted part of a piece of furniture from a closed end position in relation to a body of a piece of furniture. The ejection device can be fixed in relation to the body of the piece of furniture by an adapter plate. The adapter plate includes at least two guides, one of the guides being respectively connectable to a bearing part fixed to the body. The at least two guides can be used to position the ejection device in at least two different depth positions on or in the body of the piece of furniture.
