Drilling Jig Guide Means for Thick Insulation Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of insulating material and a waterproofing membrane on a concrete roof is challenging due to the thickness of the insulating material, which makes it difficult to align and screw a fixing piece correctly, as the screw becomes hidden in the barrel of the fixing part, hindering precise alignment with the drilled hole.
Innovation Solution
A drilling jig with guide means and a flange that secures the fastening means to the jig, allowing simultaneous drilling and installation of a fixing part in the insulating material, featuring a barrel with elastic radial friction and anti-rotation means to keep the drill bit aligned and prevent buckling, facilitating precise screw placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the insulating material is made thick to provide adequate insulation, then thermal insulation performance is improved, but the screw becomes hidden in the barrel of the fixing part making alignment difficult
Solution Approach 1:
The patent introduces a template as an intermediary tool that bridges the gap between the thick insulating material and the screw alignment. The template includes a guide means with a guide channel that receives and guides the screw, ensuring it remains aligned with the drilled hole throughout the screwing operation. This intermediary structure solves the visibility and alignment problem caused by the thick insulating material covering the hole.
Solution Approach 2:
The template is positioned and secured to the insulating material before the screwing operation begins. The guide means is pre-configured with the correct geometry and positioning to ensure the screw will be properly aligned with the hole. This preliminary setup eliminates the need for continuous visual monitoring and manual realignment during the screwing process.
2Temperature
If the insulating material thickness increases to 200 mm, then insulation effectiveness is improved, but the screw visibility and maneuverability deteriorate
Solution Approach 1:
The template serves as a mediator that provides a visual and physical reference system. The guide channel and other template features are visible and accessible from the surface, allowing the operator to detect and control screw positioning without needing to see the screw tip at the bottom of the 200 mm thick insulating material.
Solution Approach 2:
The solution moves the alignment reference from the vertical dimension (screw tip at the bottom of the hole) to the horizontal dimension (template features at the surface). By providing guide means and positioning references at the accessible surface level, the system enables screw visibility and control without requiring the operator to see deep into the hole through 200 mm of insulation.
3Productivity
If a single operation is used for drilling and screwing in thin steel, then installation efficiency is improved, but this method cannot be applied to thick insulating material on concrete
Solution Approach 1:
The template is designed as a multi-functional tool that can be adapted to different support materials (concrete, steel, etc.) and insulating material thicknesses. The guide means can be configured with different geometries and the template can be secured to various surfaces, making it universally applicable across different installation scenarios while maintaining the efficiency benefits of coordinated drilling and screwing.
Solution Approach 2:
The template system allows for dynamic adjustment and adaptation during the installation process. The guide means can accommodate different screw types and sizes, and the template positioning can be adjusted to suit different hole locations and orientations, enabling the system to maintain high efficiency across diverse application conditions.
