Solution Overview
Problem
The assembly of kitchen base cabinets with pull-out waste separation systems is complex and error-prone due to the manual positioning of connecting elements, leading to time-consuming and unreliable installations.
Innovation Solution
A mounting device with a mounting plate having two opposing surfaces, where one surface is connected to the cover element and the other to the pull-out device, featuring offset fixing elements and bores for secure attachment, allowing for a simple, fast, and reliable assembly without additional fastening elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual positioning of connecting elements is used, then assembly flexibility is maintained, but assembly time increases and assembly precision deteriorates
Solution Approach 1:
The mounting plate is pre-provided with multiple bores at predetermined positions and fixing elements at specific locations before assembly. This preliminary preparation eliminates the need for manual measurement and positioning during assembly, allowing workers to simply align and insert fasteners, thereby significantly improving assembly speed while ensuring precise positioning through the pre-defined bore locations.
Solution Approach 2:
The mounting plate serves multiple functions: it provides positioning references through pre-drilled bores, structural support through its rigid design, and connection points through multiple fixing elements. This multi-functionality consolidates several assembly operations into a single component, improving both efficiency and precision without requiring multiple separate positioning aids.
2Reliability
If multiple fixing elements are used, then connection reliability improves, but device complexity increases
Solution Approach 1:
Multiple fixing elements are integrated into a single mounting plate component rather than being separate parts. The mounting plate combines multiple fixing functions (screw fixing, clip fixing, adhesive application areas) into one unified structure, thereby improving connection reliability through multiple attachment points while avoiding the complexity of assembling multiple separate fixing components.
Solution Approach 2:
Different regions of the mounting plate are designed with different fixing characteristics: some areas have bores for screw fixation, others have projecting fixing elements for clip connections, and specific zones are prepared for adhesive application. This local differentiation provides reliable fixing through multiple methods while keeping the overall structure simple and unified.
3Adaptability or versatility
If offset fixing elements are used, then detachable fixing is enabled, but manufacturing precision requirements increase
Solution Approach 1:
The mounting plate is pre-manufactured with bores and fixing elements positioned at precisely calculated offset locations. This preliminary precision manufacturing enables the detachable fixing function to work reliably, as the offset positions are predetermined and consistent. The precision is built into the component during manufacturing rather than requiring high-precision assembly operations.
Solution Approach 2:
The fixing system is segmented into discrete, independently positionable elements (multiple bores at different locations, projecting fixing elements at offset positions). This segmentation allows the mounting plate to provide detachable fixing capabilities through selective engagement of different fixing elements, while the precision of each element's position is optimized independently during manufacturing.

AI summary
A mounting device connects a pull-out device to a cover element of a piece of furniture, in particular a piece of sanitary furniture, having a mounting plate with two opposing surfaces. The mounting device includes a first surface and an opposing second surface. In a fixed state of the mounting plate, the first surface is connected to the cover element, and the second surface is connected to the pull-out device. The first surface has at least one fixing region that can be flat. The second surface has at least two fixing elements arranged to project from the second surface. In the mounted state of the mounting plate, at least two of the fixing elements are arranged horizontally and/or vertically offset from one another, in particular on horizontally different sides of the second surface. The at least two fixing elements are formed in one piece with the mounting plate. The mounting plate has at least one bore on different sides.
