Screw Channel Edge Threading for Standard Screw Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing components using screws require complex manufacturing processes and specialized screws, making assembly and disassembly cumbersome and costly, especially in applications like scaffolding construction.
Innovation Solution
A method and system utilizing a screw channel with an edge that creates an internal thread by deforming the edge when a metric or imperial screw is inserted, eliminating the need for pre-existing internal threads and allowing for reliable, repeatable fixation using standard screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw channel with pre-formed internal thread is used, then the screw fixation is strong and reliable, but the manufacturing process becomes complex and costly
Solution Approach 1:
The screw channel is pre-configured with a specific edge geometry (protruding towards the central axis) that prepares the structure for automatic internal thread formation during screw insertion, eliminating the need for separate threading operations while ensuring reliable fixation
Solution Approach 2:
The screw insertion process itself performs the dual function of both fastening and creating the internal thread in the edge through material displacement, making the system self-servicing and eliminating separate manufacturing steps for thread formation
2Strength
If specialized screws with internal threads are used, then the fixation is robust, but the costs and manufacturing effort increase
Solution Approach 1:
Instead of forming the internal thread in the screw (as in conventional specialized screws), the invention inverts the approach by having the screw's external thread deform the edge material to create the internal thread in the component, using readily available standard screws instead of specialized ones
3Stability of the object's composition
If components are designed for permanent fixation, then the structure is stable, but repair and maintenance become difficult
Solution Approach 1:
The screw channel design allows the fixation to be dynamically reversible - the screw can be inserted to create a strong fixed connection, and later removed and reinserted for repairs or replacements, maintaining both structural stability during use and ease of repair when needed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy assembly and disassembly of components with standard screws, reducing manufacturing effort and costs while maintaining high load-bearing capacity, facilitating repair and maintenance.
Implementation Method 1
The edge is deformed by the metric or imperial external thread of the screw such that the edge, viewed in the direction of the central axis, has recesses at regular intervals into which the external thread of the screw engages

AI summary
The invention relates to a method for fixing a further component 2 to a component 1 using a metric or imperial screw 3, wherein the component 1 comprises a screw channel 4 which is bounded in cross-section by an inner cylindrical surface 5, the inner cylindrical surface 5 having an edge 6 which extends parallel to a central axis 7 of the screw channel 4 and projects towards the central axis 7 in cross-section, wherein the screw 3 is turned into the screw channel 4 in the direction of the central axis 7 to fix the two components 1, 2, thereby creating an internal thread in the edge 6. The invention further relates to a component and a system comprising the component and a screw. The components 1, 2 can thus be manufactured and assembled with particularly little effort.
