Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facade systems lack the ability to easily and securely attach and detach panel-shaped or profile-shaped components from building substrates, limiting design flexibility and reusability, as well as efficient force distribution.
Innovation Solution
A fastening element with a plate-like section and a shaft-like section, featuring pin, mushroom-head, hook, and loop-shaped connecting elements for non-positive and positive connections, allowing for secure attachment and easy removal of components, and optionally using a multi-part design for optimized material usage and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional disc anchors with receiving bores are used to fasten building elements to substrates, then secure anchoring is achieved, but easy and quick attachment and detachment is not possible
Solution Approach 1:
The fastening element is divided into a plate-like first fastening section with connecting elements and a shaft-like second fastening section for receiving the connecting element. This segmentation allows the plate section to provide secure anchoring while the shaft section enables easy attachment and detachment through the connecting element mechanism.
Solution Approach 2:
The connecting elements on the plate-like fastening section are designed to be elastically deformable, allowing them to dynamically adapt during attachment and detachment. The elastic deformation enables the connecting elements to engage with and disengage from corresponding elements on building components, facilitating quick and easy attachment and removal while maintaining secure anchoring when engaged.
2Adaptability or versatility
If conventional fastening elements are used, then structural stability is maintained, but design flexibility and reusability are limited
Solution Approach 1:
The fastening element serves multiple functions: the plate-like first fastening section with various connecting elements (pin, mushroom-head, hook, loop-shaped) provides versatility for different building components and configurations, while the shaft-like second fastening section ensures secure anchoring to the substrate. This multi-functionality enables design flexibility and reusability without compromising structural stability.
Solution Approach 2:
The fastening element is designed to be reusable rather than single-use. After detachment, the elastic connecting elements return to their original shape, allowing the fastening element to be reused for subsequent alignment or replacement of building components, thereby enhancing design flexibility and reducing material waste.
3Strength
If simple plate anchors are used, then easy attachment is achieved, but effective force distribution and secure anchoring are insufficient
Solution Approach 1:
The fastening element is segmented into a plate-like first fastening section for force distribution and a shaft-like second fastening section for anchoring. This segmentation allows each section to be optimized for its specific function while working together to provide effective force distribution and secure anchoring without excessive overall complexity.
Solution Approach 2:
Different parts of the fastening element have different local properties: the plate-like section provides a large surface area for force distribution, while the shaft-like section provides concentrated anchoring strength. The connecting elements have localized elastic properties for easy engagement and disengagement. This local quality optimization achieves effective force distribution and secure anchoring with minimal overall complexity.
