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

VSEngineering 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

Engineering Contradiction:
Improveforce distributionVSAvoidtorque requirement
Core Design Contradiction:
ForceVSUse of energy by moving object

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.

Inventive Principle:
Principle #31Porous materials

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

Engineering Contradiction:
Improveinstallation speedVSAvoidinstallation process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

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.
