Positioning Device Spacer for Insulation Board Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning devices for insulating material holders require multiple dowel lengths to accommodate varying substrate thicknesses, leading to inefficiencies and increased working time, especially in old buildings with thicker non-load-bearing substrates.
Innovation Solution
A versatile positioning device that adjusts the position of the insulating material holder based on the thickness of the non-load-bearing substrate, using a single dowel length and optional spacers marked for 'new' and 'old' building types, allowing for tool-free attachment and precise drilling depth compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple dowel lengths are used to accommodate varying substrate thicknesses, then the positioning device can adapt to different building types, but the device complexity and working time increase
Solution Approach 1:
The positioning device uses a single dowel length that serves multiple functions by combining it with interchangeable spacers. The spacers are selectively attachable to the dowel to create different total lengths, allowing one dowel to function as multiple effective lengths for different substrate thicknesses. This eliminates the need for multiple dedicated dowels while maintaining adaptability.
Solution Approach 2:
The positioning device is segmented into modular components: a base dowel and separate spacers. These segments can be combined in different configurations by attaching the appropriate spacer to the dowel, enabling adaptation to various substrate thicknesses without requiring a complete set of different-length dowels.
2Adaptability or versatility
If multiple dowel lengths are used to accommodate varying substrate thicknesses, then the positioning device can adapt to different building types, but the loss of time in selection and operation increases
Solution Approach 1:
The spacers are pre-manufactured with specific lengths and attachment features that correspond to different substrate thickness requirements. The installer can quickly select and attach the appropriate spacer to the standard dowel based on the building type, eliminating the need to search through multiple dowel lengths and reducing selection time.
3Strength
If the insulation holder is screwed all the way into the insulation board, then the anchor is securely fastened, but the drilling depth into the load-bearing substrate increases unnecessarily
Solution Approach 1:
The spacer acts as an intermediary element between the dowel and the insulation board. It provides the necessary positioning and fastening function without requiring the dowel to extend through the entire thickness of the insulation board into the load-bearing substrate. The spacer mediates the connection, allowing secure fastening with reduced drilling depth.
4Adaptability or versatility
If spacers are made selectively attachable to the screwing tool, then the device can be adapted to different insulation board thicknesses, but the ease of operation decreases
Solution Approach 1:
The spacers are pre-configured with attachment features that simplify the selection and attachment process. The installer only needs to choose the appropriate spacer based on the insulation board thickness and attach it to the dowel, rather than dealing with complex adjustment mechanisms or multiple specialized tools.
