Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively dissipate the energy of explosions, particularly in the technical field of the construction of structures, specifically in terms of protecting structures from the potential collapse caused by explosions, especially in military and industrial settings, where conventional methods do not adequately address the instability and local collapse issues.
Innovation Solution
An explosion energy dissipating connector is used, comprising a sacrificial panel and dissipating connectors with energy absorption capacity, which absorbs and redistributes the loading from explosions through tubular inversion and core crushing mechanisms, ensuring the structure's stability by preventing direct contact with critical elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid elements are used to couple panels to the structure, then the panels are securely attached, but all explosion loads are transferred directly to the structure causing potential collapse
Solution Approach 1:
The patent introduces an intermediary energy-dissipating device between the panel and the structure. This device includes a deformable element that acts as a mediator, absorbing explosion energy through controlled deformation and preventing direct load transfer to the critical structural elements, thus resolving the contradiction between secure attachment and load protection
Solution Approach 2:
The energy-dissipating device uses sacrificial deformable elements designed to undergo permanent deformation or failure during explosion events. These elements are intentionally designed as consumable components that absorb energy through their destruction, protecting the more valuable permanent structure while accepting the loss of the disposable energy-absorbing elements
2Loss of energy
If dissipative devices are added to planar elements, then some energy is dissipated, but the maximum distance available for energy dissipation is very small limiting effectiveness
Solution Approach 1:
The patent transitions from planar surface-mounted dissipative devices to a three-dimensional deformable element that can compress axially. By utilizing the third dimension (axial compression direction) rather than relying solely on surface area, the system achieves significantly greater energy dissipation capacity through controlled collapse mechanisms that exploit volumetric deformation space
3Ease of manufacture
If the outer structure is just juxtaposed to the existing structure, then installation is simple, but all loads are transferred to contact elements causing local collapse
Solution Approach 1:
The patent inserts an intermediary coupling system between the juxtaposed structures that includes energy-dissipating components. This intermediary layer maintains the simplicity of juxtaposition installation while introducing controlled deformation elements that prevent direct load paths, thus preserving both installation ease and structural stability under explosion loads
