Adjustment Dowel for Insulation Surface Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulation systems face challenges in achieving a homogeneous surface due to uneven substructures and varying densities of insulating materials, leading to complex leveling and gluing processes, and potential stress cracks under environmental influences.
Innovation Solution
A dowel with a fastening element that allows stepless adjustment of the distance between the insulating material and the substructure, enabling flexible positioning and compression/decompression without loosening the anchoring, using a mechanism with a thread or expanding element for secure anchoring and adjustable holding means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a known retaining element is used to fasten insulating material to a substructure, then the insulation material is securely fixed, but the surface becomes uneven due to substructure unevenness and varying compression levels
Solution Approach 1:
The retaining element incorporates an adjustable holding means that can be continuously repositioned along the fastening element's length. This dynamic adjustment capability allows the holding means to be positioned at different distances from the substructure, compensating for surface unevenness and enabling creation of a uniform insulation surface while maintaining secure fastening.
Solution Approach 2:
The invention changes the parameter of distance between the holding means and the substructure by allowing continuous adjustment of the holding means position along the fastening element. This parameter change enables adaptation to varying substructure conditions and insulation material densities, achieving both secure fastening and surface uniformity.
2Reliability
If the retaining element compresses the insulation material to ensure contact with the substructure, then fastening is secure, but uneven pressure distribution causes misalignment and surface unevenness
Solution Approach 1:
The adjustable holding means allows dynamic control of compression force distribution. By repositioning the holding means along the fastening element, uniform pressure can be applied across the insulation board surface, preventing misalignment while maintaining secure contact with the substructure.
3Ease of manufacture
If the holding means is fixed at a specific position on the fastening element, then the installation is simple, but the distance between insulation material and substructure cannot be adjusted
Solution Approach 1:
The holding means is designed to be movable along the fastening element rather than fixed, providing continuous adjustability of the insulation material distance from the substructure. This dynamic design maintains relative installation simplicity while significantly improving adaptability to different installation conditions.
Solution Approach 2:
The adjustable mechanism serves multiple functions: it secures the insulation material, allows distance adjustment, and enables adaptation to various substructure conditions. This multi-functionality achieves both ease of installation and versatility without requiring multiple different retaining elements.
4Adaptability or versatility
If the fastening element is loosened to adjust the holding means position, then the distance can be changed, but the anchoring strength is reduced
Solution Approach 1:
The fastening element is segmented into distinct functional zones: an anchoring region that secures the element in the substructure and a adjustment region where the holding means can be repositioned. This segmentation allows the holding means to be adjusted along the fastening element without requiring loosening of the anchoring portion, maintaining anchoring strength while enabling distance adjustability.
