Insulation Screw Insertion with High-Lead Thread and Upright Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulation screws are time-consuming and costly to insert, often damaging insulation materials due to their design, and require users to bend down repeatedly, which is ergonomically unfavorable.
Innovation Solution
An insulation screw with a lead pitch of at least 30 millimeters, designed for use with a mounting device that allows complete insertion in one operation step without rotating the head, ensuring controlled rotation and minimizing material damage, allowing users to stand upright during insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional insulation screws with standard lead pitch are used, then the screw can be inserted into insulation material, but the insertion process is time-consuming and requires multiple operation steps
Solution Approach 1:
The patent applies parameter changes by increasing the lead pitch of the screw thread from conventional values to at least 30 mm. This parameter modification allows the screw to advance further with each rotation, significantly reducing the number of rotations needed for insertion and enabling complete insertion in a single operation step, thus improving productivity and reducing insertion time
Solution Approach 2:
The mounting device performs preliminary action by pre-positioning and pre-aligning the insulation screw before insertion. The device holds the screw in the correct orientation and applies initial force, allowing the user to stand upright and eliminating the need for bending and repositioning during the insertion process
2Reliability
If insulation screws are inserted by conventional methods, then the screw can be attached to insulation panels, but the threaded section may function as a drill and destroy the insulation material
Solution Approach 1:
The mounting device performs preliminary action by creating a pilot hole or preparing the insertion path before the threaded section engages the insulation material. This preliminary preparation ensures that the screw follows the correct path and the threads engage properly without acting as a drill, preventing material destruction while maintaining reliable holding force
Solution Approach 2:
The mounting device acts as an intermediary between the user and the insulation screw. It controls the insertion process, manages the rotational speed and pressure application, and ensures that the screw is inserted with appropriate parameters to prevent the threaded section from damaging the insulation material
3Ease of operation
If conventional insulation screws are used, then the screw can be inserted into insulation panels, but the user must bend down repeatedly which is ergonomically unfavorable
Solution Approach 1:
The mounting device performs preliminary action by pre-positioning the insulation screw in an easily accessible location and maintaining it there throughout the insertion process. This allows the user to stand upright and perform the insertion without bending down repeatedly, significantly improving ergonomic performance and reducing physical strain
Solution Approach 2:
The mounting device changes the operational dimension by allowing vertical insertion while the user stands upright, rather than requiring horizontal or downward insertion that would necessitate bending. This dimensional change in the insertion approach eliminates the ergonomic disadvantage of repeated bending

AI summary
Insulation screw adapted to be inserted by a mounting device into insulation material, where the insulation screw comprises a body provided with at least one thread, where the tip of the body is pointed, where the outer diameter of the head is equal to or smaller than the outer diameter of the body and where the lead pitch of the thread is at least 30 millimetres. An insulation screw can be driven completely through a central opening since the insulation screw does not have a protruding head. The insulation screw is provided with a thread and the opening of a mounting device is provided with a corresponding threaded portion, such that the insulation screw is screwed into the insulation material by a non-rotating pushing force.
