Furniture Fitting Fastener with Threadless-Guided Thread Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fittings for movably mounting furniture parts, doors, or windows on support structures have complex designs, making the fastening process difficult and increasing the risk of incorrect operation.
Innovation Solution
A fitting with a fastening device comprising a first component with a threadless and threaded section, and a second component with a mating thread, allowing for quick and easy assembly by transitioning from a displacement position to an engagement position through a pivoting movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a complex fastening design is used, then the fitting can securely mount heavy furniture parts, but the fastening process becomes more difficult and time-consuming
Solution Approach 1:
The fastening device is segmented into distinct functional zones: a threadless section for initial contact and positioning, and a threaded section for final securing. This segmentation allows the operator to perform simple linear insertion first, then engage the threading mechanism separately, breaking down a complex fastening operation into manageable steps that maintain strength while improving ease of operation.
Solution Approach 2:
The fastening mechanism transitions from a single-dimensional linear insertion to a two-dimensional operation by incorporating angular engagement. The threaded section engages at an angle relative to the threadless section, allowing the fastening process to proceed in multiple directional phases, which simplifies the overall operation while maintaining secure attachment.
2Reliability
If a complex fastening design is used, then the fitting can provide secure mounting, but the risk of incorrect operation increases
Solution Approach 1:
By dividing the fastening interface into distinct threadless and threaded sections, the design provides clear visual and tactile cues that guide the operator through the correct sequence of operations. The threadless section serves as a guide that must be engaged first, followed by the threaded section, making it difficult to perform the fastening incorrectly while still achieving reliable mounting.
Solution Approach 2:
The threadless section performs a preliminary positioning and alignment function before the threaded section engages. This preliminary action ensures that the components are correctly oriented and seated before the final securing operation, preventing incorrect operation while maintaining mounting reliability.
3Strength
If traditional threaded fastening is used throughout, then secure connection is achieved, but the installation process becomes more difficult especially with multiple fastening devices
Solution Approach 1:
The fastening device is segmented into a threadless section for rapid initial engagement and a threaded section for secure final connection. This allows operators to quickly position multiple fastening devices using the threadless section, then efficiently engage the threaded sections, significantly reducing total installation time while maintaining connection strength.
Solution Approach 2:
The threadless section enables preliminary positioning and alignment of multiple fastening devices simultaneously or in rapid succession. This preliminary action eliminates the need for time-consuming alignment and adjustment that would be required with fully threaded fasteners, reducing installation time while the subsequent threading provides the necessary connection strength.

AI summary
A fitting for movably mounting a furniture part, a door, or a window on a support structure, includes a first fitting part to be connected to the furniture part, the door, or the window, and at least one second fitting part to be connected to the support structure. At least one securing device can secure the first fitting part to the second fitting part. The securing device includes a first component with at least one thread-free section and a threaded section and a second component with at least one mating thread. The thread-free section, the threaded section, and the mating thread are arranged on the two components of the securing device such that the mating thread contacts the thread-free section in a sliding position and is engaged with the threaded section in an engagement position.
