Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern buildings with panel facades are susceptible to explosive forces, which can damage the panels and pose a risk to occupants, and existing blast absorption devices are often bulky, difficult to install, and require multiple configurations to cater to varying blast loads, leading to increased costs.
Innovation Solution
A panel assembly with extendable connecting assemblies that include a controlling portion and a connecting portion, where the connecting portion is clamped between plates to control its extension and absorb blast energy, allowing the panel to move in a controlled manner and dissipate energy without being blown away or shattered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional blast absorption devices are used to protect panels from explosive forces, then the blast load capacity is improved, but the device complexity and installation difficulty increase significantly
Solution Approach 1:
The patent employs flexible connecting assemblies with cable networks and elastic elements that can deform and extend under blast loads. These flexible components absorb explosive forces through controlled deformation rather than rigid resistance, reducing the complexity of bulky protective structures while maintaining blast load capacity. The flexible nature allows the system to cater to varying blast intensities without requiring multiple device configurations.
Solution Approach 2:
The connecting assemblies are designed with dynamic characteristics, allowing them to extend and contract based on the applied blast load. The elastic elements and cable networks can dynamically adjust their stiffness and energy absorption capacity, enabling a single device type to handle a range of blast intensities. This dynamic behavior eliminates the need for multiple static devices with different blast load capacities.
2Adaptability or versatility
If multiple devices with different blast load capacities are fabricated to cater to varying explosive loads, then the adaptability to different blast levels is improved, but the manufacturing cost and storage requirements increase
Solution Approach 1:
The connecting assembly is designed as a universal component that can handle multiple blast load levels through its extendable and elastic characteristics. The same device type can be used across different panel locations regardless of the expected blast intensity, as the assembly will naturally extend further or compress more under higher loads. This multi-functionality eliminates the need to manufacture and store multiple device variants with different blast load capacities.
Solution Approach 2:
The system utilizes parameter changes in the connecting assembly's physical state during operation. The elastic elements and cable networks change their effective stiffness, length, and energy absorption capacity based on the applied load magnitude. This allows a single device configuration to adapt to varying blast intensities by changing its mechanical parameters dynamically rather than requiring different device designs for different load levels.
3Stability of the object's composition
If panels are secured rigidly to withstand blast forces, then the structural stability is improved, but the energy absorption capability and damage mitigation are reduced
Solution Approach 1:
The connecting assemblies incorporate elastic elements and flexible cable networks that act as pre-configured cushioning mechanisms. These components are designed to deform and absorb energy during blast events, providing beforehand cushioning that protects the panels from direct blast impact. The elastic deformation of these elements dissipates explosive energy before it can damage the panels or occupants, while maintaining structural stability through controlled flexibility rather than rigid fixation.
