Assembly Aid Tool for Marking Concealed Sliding Door Fitting Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concealed installation of sliding door fittings in furniture makes it difficult to mark and assemble the correct position during installation, as the position can only be determined when both doors are closed, and existing methods lack a straightforward solution for marking the assembly position.
Innovation Solution
An auxiliary assembly tool with angular configuration, featuring a first leg with spikes for marking the furniture door and a second leg with a displaceable tab and mandrel receptacle, allows for marking the furniture door's inner surface when closed, enabling accurate positioning of the sliding door fitting's components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the sliding door fitting is installed in a concealed manner between the furniture door and appliance door, then the aesthetic appearance is improved, but the ability to mark and determine the assembly position is worsened
Solution Approach 1:
The auxiliary assembly tool is attached to the appliance door before the actual installation of the sliding door fitting. This preliminary action allows the tool to mark the correct assembly position on the furniture door while both doors are in the closed state, thereby solving the positioning problem that arises from concealed installation.
Solution Approach 2:
The auxiliary assembly tool acts as an intermediary device between the appliance door and the furniture door. It transfers the positional relationship between the two doors by marking the furniture door based on the tool's position on the appliance door, enabling accurate positioning without direct access to the concealed installation space.
2Reliability
If the position of the sliding door fitting is determined only when both doors are closed, then the functional coupling is improved, but the assembly process complexity is worsened
Solution Approach 1:
The correct assembly position is marked in advance when both doors are closed and in the correct functional position. This preliminary marking eliminates the need for complex measurements and adjustments during the actual assembly process, thereby reducing assembly complexity while maintaining functional reliability.
Solution Approach 2:
The auxiliary assembly tool copies the positional relationship between the appliance door and furniture door by transferring the position of the appliance door to the furniture door through marking. This copying process simplifies the assembly process by providing a direct reference for positioning without requiring complex functional testing.

AI summary
The invention relates to a method for assembling a sliding door fitting (40) by means of which a device door (21) of a fitting device (20) which is installed into a furniture body (10) is coupled to a furniture door (11) of the furniture body (10). The method has the following steps: - installing the fitting device (20) into the furniture body (10); - fixing an assembly aid tool (30) to the device door (21); - closing the device door (21) and closing and pressing the furniture door (11), whereby markings (121) are introduced onto an inner surface (12) of the furniture door (11) by means of pins (312) of the assembly aid tool (30); - opening the furniture door (11) and releasing and removing the assembly aid tool (30); - positioning a base housing (41) of the sliding door fitting (40) using the markings (121); - securing the base housing (41) to the furniture door (11); and - fixing a slider (44) of the sliding door fitting (40) to the device door (21). The invention further relates to an assembly aid tool (30) which is characterized in that the assembly aid tool (30) has an angular shape with a first limb (31) and a second limb (32). The first limb (31) has at least one pin (312) for introducing at least one marking (121) onto the furniture door (11), and the second limb (32) has a securing opening for fixing the assembly aid tool (30) onto an end face (23) of the device door (21).
