Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current panel fixing systems fail to accommodate structural deformations and dimensional tolerances in building structures, leading to mechanical stress and potential damage during load variations or earthquakes, and struggle with aligning panels on non-straight edges.
Innovation Solution
A non-rigid fastening system comprising a stirrup with a U-shaped shoe and a connecting piece with a sliding stud, allowing for three-dimensional adjustment and absorption of structural variations, along with a positioning bracket and leveling wedge for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid fixing systems are used to securely attach panels to structural elements, then panel fixation strength is improved, but the system cannot accommodate structural deformations and dimensional tolerances, leading to mechanical stress and potential damage
Solution Approach 1:
The connecting piece incorporates a slot that allows the stud to slide longitudinally, transforming the rigid connection into a dynamic one. This enables the panel fixing system to adapt to structural deformations and dimensional variations while maintaining secure attachment, resolving the contradiction between fixation strength and adaptability.
Solution Approach 2:
The slot in the connecting piece changes the positional parameter of the stud along the longitudinal axis, allowing adjustment to accommodate structural tolerances and deformations. This parameter change enables the system to maintain strong fixation while adapting to varying structural conditions.
2Reliability
If rigid fixing systems are used to ensure panels remain fixed during movements, then anti-seismic performance is improved, but the system transmits mechanical stresses that can damage panels during slab displacement
Solution Approach 1:
The slot acts as an intermediary mechanism between the stud and the structural element, allowing relative movement while maintaining connection. This intermediary enables the system to withstand seismic displacements without transmitting damaging mechanical stresses to the panels, thus improving reliability while reducing harmful effects.
Solution Approach 2:
The slot provides a predetermined movement path that cushions against seismic forces by allowing controlled sliding of the stud. This beforehand cushioning mechanism protects the panels from sudden mechanical stress transmission during earthquake-induced slab displacements.
3Manufacturing precision
If panels are perfectly flat and rigidly fixed, then manufacturing precision is improved, but it becomes difficult to correctly fix panels on structural elements with non-straight edges
Solution Approach 1:
The slot allows the connecting piece to dynamically adjust its position to accommodate non-straight edges of structural elements. This dynamic adjustment capability enables correct fixation of perfectly flat panels on imperfect structural surfaces, resolving the contradiction between manufacturing precision and ease of operation.
Solution Approach 2:
The longitudinal sliding capability of the stud in the slot changes the positional parameter of the connection point, allowing adaptation to varying edge geometries of structural elements. This parameter change enables easy fixation of precision-manufactured panels on non-straight edges.
