Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building exterior and interior material systems lack sufficient earthquake resistance, with existing methods being inefficient, economically unviable, and prone to damage during seismic events due to heavy loads and poor workability.
Innovation Solution
A factory-assembled exterior material unit system using lightweight aluminum frames with guide grooves, clips, and anchor bolts, allowing for flexible installation and improved seismic performance, reducing workforce requirements and construction time while enhancing productivity and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a grid-form frame structure with holding brackets and finishing panels is installed, then the structural stability is improved, but the load increases making the system vulnerable to earthquakes
Solution Approach 1:
The patent extracts the heavy grid-form frame structure and replaces it with a simplified anchor bolt system. The finishing panels are directly anchored to the wall through brackets without requiring a comprehensive frame grid, thereby removing unnecessary structural weight while maintaining essential stability.
Solution Approach 2:
The system is segmented into discrete anchor bolt locations rather than a continuous frame grid. The brackets are positioned at specific intervals to provide necessary support while leaving gaps that reduce overall material usage and structural weight.
2Adaptability or versatility
If all construction work is carried out at the work site, then the adaptability to site conditions is improved, but the workability and constructability deteriorate
Solution Approach 1:
The brackets and finishing panels are prepared and positioned according to pre-determined anchor locations before the actual installation. The anchor bolt holes are marked and prepared in advance, allowing for systematic and efficient installation rather than improvising during construction.
3Strength
If the fixed part is fastened to the outer wall with bolts, then the structural strength is improved, but the durability deteriorates as the fixed part is easily separated during vibration
Solution Approach 1:
The bracket design incorporates movement capability that allows the finishing panel to respond dynamically to seismic vibrations. The bracket can move or deform elastically during earthquake vibrations, absorbing energy and preventing catastrophic failure while maintaining the structural connection.
4Reliability
If a moving member is inserted into the guide rail for vibration absorption, then the earthquake resistance is improved, but the device complexity increases
Solution Approach 1:
The bracket is designed with flexible elements that can deform and move to absorb vibration energy. Rather than using a complex moving member within a guide rail, the bracket itself incorporates flexible characteristics through its geometry and material properties, allowing simple yet effective seismic response.
