Façade Board Fastener Geometry for Precise Plane Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fasteners for mounting façade boards to substructures do not adequately ensure precise alignment and stability in a defined plane, particularly for fibre-cement boards, and lack efficient mounting mechanisms.
Innovation Solution
A fastener design comprising a support leg, fastening and bottom legs with bended portions, and flaps, which allows for precise fixation of façade boards in a defined plane, utilizing a fastening device to secure the fastener to the substructure, with bended portions enhancing stability and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional fastener with simple leg structure is used to mount façade boards, then the device complexity is low and ease of manufacture is high, but the alignment precision and stability in a defined plane are insufficient
Solution Approach 1:
The fastener is divided into multiple functional segments: support leg for mounting, fastening leg with opening for fastening device, bottom leg for additional support, top flap and bottom flap for plane definition and board engagement. Each segment performs a specific function to achieve precise alignment and stability.
Solution Approach 2:
The fastener extends in multiple spatial dimensions with legs extending in top and bottom directions, and flaps extending from front and rear edges. This multi-dimensional structure provides precise positioning in three-dimensional space, ensuring the façade board is fixed in a well-defined plane.
2Stability of the object's composition
If a fastener with multiple legs and flaps is used to ensure stability and alignment, then the manufacturing precision and stability are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
Multiple functional elements (support leg, fastening leg, bottom leg, top flap, bottom flap) are merged into a single integrated fastener component. This unified structure provides stable mounting while simplifying manufacturing compared to assembling multiple separate parts.
Solution Approach 2:
The fastener performs multiple functions simultaneously: the support leg provides mounting support, the fastening leg with opening secures the fastening device, the bottom leg provides additional support, and the flaps define the mounting plane and engage with the board. This multi-functionality achieves stable positioning without requiring multiple separate components.
3Manufacturing precision
If existing fasteners are used for fibre-cement façade boards, then the mounting process is simple, but the fasteners do not provide adequate alignment control and plane definition
Solution Approach 1:
The fastener structure itself, with its specific geometry of legs and flaps, automatically defines the mounting plane and provides alignment control during the fastening operation. The flaps extend to engage with the façade board and establish a well-defined plane, while the legs provide stable support, making the alignment function inherent to the fastener design.
