Container Wall Composite Reduces Weight and Boosts Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current construction elements for containers are heavy due to thick walls made of concrete, which compromises their mobility and security, as they require significant effort and time to force, and existing solutions do not effectively balance weight and security.
Innovation Solution
A construction element comprising steel walls with transversally arranged sheet components and concrete in between, where the sheet components are welded to the walls and include holes for rebar, openings for concrete distribution, and additives like wood or metal pellets to reduce weight while increasing security by making penetration difficult and time-consuming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thick concrete walls are used in construction elements, then security and resistance to forcing are improved, but weight and mobility are worsened
Solution Approach 1:
The patent applies composite materials by combining steel sheet components with concrete in a layered construction element. The steel sheets provide structural strength and security resistance, while the concrete fills the spaces between sheets to provide additional protection and structural integrity. This composite approach achieves high security without requiring uniformly thick concrete walls, thereby reducing overall weight compared to traditional thick concrete construction.
Solution Approach 2:
The construction element is segmented into multiple steel sheet components arranged in parallel, with spaces between them filled with concrete. This segmentation allows the structure to achieve security through multiple layers of different materials rather than a single thick concrete wall, optimizing the weight-to-security ratio by using steel's higher strength-to-weight ratio in critical load-bearing positions.
2Reliability
If thick concrete walls are used to prevent forcing, then security against burglary is improved, but time and effort required for forced entry increase
Solution Approach 1:
The composite structure of steel sheets with concrete infill creates a multi-material barrier that resists forcing attempts. The steel sheets provide immediate structural resistance to cutting and piercing tools, while the concrete infill adds time-consuming resistance to demolition and forced entry. This combination significantly increases the time and effort required for forced entry compared to simple concrete or steel structures.
Solution Approach 2:
The segmented arrangement of steel sheets with concrete fill creates multiple resistance layers that must be penetrated sequentially. An attacker must overcome the steel sheets' resistance to cutting/piercing, then penetrate through the concrete infill, making the overall forced entry process more time-consuming and complex compared to single-material constructions.
3Strength
If steel sheet components are added between walls, then security and structural strength are improved, but device complexity increases
Solution Approach 1:
The construction element is divided into modular components: steel sheet components with standardized openings and concrete fill sections. This segmentation allows for simplified manufacturing and assembly of individual parts that can be combined to form the complete wall structure, reducing overall complexity compared to monolithic construction while maintaining enhanced strength.
Solution Approach 2:
The steel sheet components serve multiple functions simultaneously: they provide structural strength, create spacing for concrete infill, provide attachment surfaces for reinforcement bars, and offer security resistance. This multi-functionality reduces the need for separate components, thereby reducing device complexity while achieving enhanced structural strength.
