Furniture Fitting Insert Assembly for Thin-Panel Hidden Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Furniture fittings that are hidden from view after assembly are challenging to design, especially in thin-walled constructions where stability and visual appeal are compromised due to insufficient support for fasteners, leading to potential instability and unsightly manufacturing flaws.
Innovation Solution
A compact design is achieved by arranging the insert element transversely to the furniture fitting with a fastening element and counter-retaining element, using a plate-like insert element that fits into a recess on the front panel, allowing for thin-walled panels and a visually appealing connection with a shadow gap to compensate for tolerance deviations and conceal manufacturing imperfections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a very thin-walled construction of side frames and front panel is desired, then the visual appeal and space utilization are improved, but the furniture fittings or fasteners no longer have enough support in the base material and the stability is impaired
Solution Approach 1:
The insert element is arranged essentially transversely to the furniture fitting, creating a cross connection that distributes loads across multiple dimensions. This transverse arrangement allows the fastening element to engage with the insert element rather than directly with the thin-walled front panel, effectively adding a structural dimension that compensates for the reduced wall thickness.
Solution Approach 2:
The insert element serves as an intermediary component between the furniture fitting and the thin-walled front panel. By inserting the insert element into the recess in the front panel and connecting it to the furniture fitting via the fastening element, the system achieves stable fastening without requiring thick panel material, as the insert element provides the necessary structural interface.
2Shape
If the furniture fitting should remain hidden inside the side frame or front fitting, then the visual appeal is improved, but the assembly and fastening become more complex
Solution Approach 1:
The connecting means is segmented into multiple components: the insert element that is partially visible in the recess, the furniture fitting that remains hidden, and the fastening element that secures them together. This segmentation allows the visible insert element to provide structural function while the hidden furniture fitting maintains aesthetic appeal, and the modular design simplifies assembly compared to fully concealed traditional methods.
3Volume of moving object
If the insert element and furniture fitting are arranged essentially transversely to one another, then a compact design is achieved, but the assembly precision requirements increase
Solution Approach 1:
The insert element is inserted into a recess provided in the front panel, creating a nested arrangement where the insert element fits within the designated space. This nesting approach achieves compactness by utilizing the available space efficiently while the form-fitting connection between the insert element and recess provides inherent alignment that reduces assembly precision requirements despite the transverse arrangement.
