Insulation Panel Mounting Tool With Slip Clutch Depth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly tools for driving screws into plate dowels for insulation boards struggle with maintaining a constant penetration depth and reproducible connection, leading to potential damage of the screw head and difficulty in loosening the dowel connection, especially for surface-flush installations.
Innovation Solution
An assembly tool featuring a non-rotatable inner body with a screwdriver bit, a slip clutch between the drive shaft and inner body, and a concentrically constructed slip clutch that ensures a constant penetration depth by maintaining the positive connection between the driving profile and screw head, and an adjustable slip clutch to prevent dowel marks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the stop washer diameter is increased to prevent marks in insulation board, then the load-bearing surface of the screw connection decreases, causing screw head damage and difficulty in loosening
Solution Approach 1:
The tool is segmented into a stationary outer body and a movable inner body that can shift relative to each other. This segmentation allows the stop washer to remain large in diameter for preventing marks while the inner body displacement maintains adequate load-bearing surface contact between the screw head and drive mechanism.
Solution Approach 2:
The inner body is designed to be movable relative to the outer body during the screwing process. This dynamic adjustment allows the system to adapt to different stages of screw insertion, maintaining optimal contact conditions while preventing surface damage through the larger stop washer.
2Manufacturing precision
If the screw is driven further into the substructure to ensure secure fastening, then the penetration depth increases, but the load-bearing surface of the screw connection becomes smaller
Solution Approach 1:
The tool incorporates a spring element that provides force feedback during the screwing process. The spring's resistance increases as the inner body displaces, providing tactile feedback to the operator about the penetration depth and connection status, enabling precise control to maintain both depth consistency and connection strength.
Solution Approach 2:
The movable inner body dynamically adjusts its position relative to the outer body during screw insertion, allowing the system to maintain optimal load-bearing surface contact while achieving the required penetration depth into the substructure.
3Object-affected harmful factors
If the assembly tool is designed with a large stop washer to prevent marks, then the handling complexity increases, but the penetration depth control improves
Solution Approach 1:
The tool is divided into modular components (outer body, inner body, spring element) that can be independently manufactured and assembled. This segmentation allows the large stop washer to be integrated without proportionally increasing overall tool complexity, as each component has a specific function.
Solution Approach 2:
The movable inner body mechanism serves multiple functions: it accommodates the large stop washer, maintains load-bearing surface contact, controls penetration depth, and provides operational feedback. This multi-functionality reduces the need for additional separate components, managing overall tool complexity.

AI summary
The invention relates to an assembly tool for driving a screw into a disc anchor for fastening an insulation board to a substructure. The invention also relates to a method for mounting an insulation board to a substructure using such an assembly tool. To ensure a consistently uniform penetration depth of the disc anchor's head into the insulation board, particularly for precise flush mounting, an assembly tool is proposed comprising a tool housing, a stop disc non-rotatably connected to the tool housing, an inner body movable along a longitudinal axis, a drive shaft, and a slip clutch integrated into the inner body and arranged between the drive shaft and the inner body. Furthermore, a method for mounting an insulation board to a substructure using such a tool is described.
