Insulation Holder with Milling Profile for Torque Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating material holders face challenges in achieving efficient assembly and distribution of forces in soft insulation materials without being pulled through the insulation board, leading to high torque requirements during installation.
Innovation Solution
The insulating material holder features a disc-shaped insulation plate with profiling elevations that rotate to mill and grind insulation material, creating a friction-reducing intermediate layer, allowing for effective force distribution and reduced torque, with a spiral arrangement of elevations for efficient material removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a flat insulation disc is used to distribute force over a large surface area, then force distribution is improved, but the torque required for installation increases due to high friction
Solution Approach 1:
The insulation disc incorporates a porous structure that allows insulation material particles to penetrate into the disc during installation. This penetration creates a self-lubricating effect where the particles reduce friction between the disc and the insulation material, thereby lowering the torque required for installation while maintaining effective force distribution across the disc surface.
2Productivity
If the insulation holder is rotated using a rotary tool for efficient material removal, then installation speed is improved, but the complexity of the installation process increases
Solution Approach 1:
The insulation holder is designed with a universal interface that accepts both manual rotation and rotary tool operation. The holder incorporates a driving recess that can accommodate various drive types, allowing the same holder to be installed using either manual rotation for simple applications or rotary tools for high-productivity applications, thereby providing multi-functionality without increasing the holder's inherent complexity.

Function Achieved in This Case
This configuration significantly reduces the torque required for screwing, enhancing assembly efficiency and user handling while maintaining a secure hold in soft insulation materials.
Implementation Method 1
The profile is designed such that, when the insulation disc is rotated around its longitudinal axis using a rotary tool, it is suitable for the local removal of insulation material beneath the insulation disc by milling, loosening, and/or grinding away portions of the insulation board during countersunk installation.
Implementation Method 2
The raised sections are designed to mill and grind insulation material, creating a friction-reducing intermediate layer
