Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unitized post tension systems for concrete masonry structures face challenges in accommodating larger wall widths, horizontal decks, and structural grade beams, requiring special construction methods, molds, and increased labor, while lacking adaptability for quasi-marsh areas and not fully utilizing the strength potential of standard concrete masonry units.
Innovation Solution
A mechanically secured block assembly system using a masonry block with recessed channels and anchor bars with specific aperture configurations, allowing for the assembly of multiple width walls, grade beams, and horizontal decks with simpler tools, reducing the need for specialized equipment and labor, and enhancing structural strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If existing unitized post tension systems are used for larger wall widths over eight inches, then wall width capacity is improved, but device complexity and manufacturing requirements worsen due to special molds and construction methods being required
Solution Approach 1:
The patent applies universality by designing a single standardized block configuration that can serve multiple functions: standard wall construction, wider wall assemblies (10-12 inch widths), grade beams, and horizontal decks. The block's recessed channels and aperture patterns are designed to accommodate various structural applications without requiring special molds or custom configurations, thereby reducing device complexity while maintaining expanded wall width capacity.
Solution Approach 2:
The patent segments the structural system into standardized blocks that can be assembled in different configurations. By dividing the wall assembly into modular units with standardized connection features (recessed channels and aperture patterns), the system enables wider walls to be constructed from standard blocks rather than requiring monolithic special molds, thus reducing manufacturing complexity.
2Area of stationary object
If wider blocks (10-12 inch widths) are used to achieve larger wall widths, then wall width capacity is improved, but ease of manufacture worsens due to requiring all new wider molds and additional tooling
Solution Approach 1:
The patent makes the block design universal by creating a single standardized configuration that can be used for standard walls and wider wall assemblies. The recessed channels and aperture patterns are designed to work with existing mold tooling while enabling the blocks to serve multiple structural functions including wider wall constructions, thereby eliminating the need for separate molds for different wall widths.
Solution Approach 2:
The patent merges the functions of standard block construction and wide wall construction into a single block design. By combining the structural requirements of both standard and wide wall applications into one standardized block configuration with appropriate recessed channels and aperture patterns, the system eliminates the need for separate mold sets and tooling for different wall width applications.
3Ease of operation
If traditional mortar construction is used, then construction simplicity is maintained, but structural strength and build speed worsen
Solution Approach 1:
The patent replaces the traditional mortar-based mechanical bonding system with a direct mechanical interlocking system. The blocks feature recessed channels and aperture patterns that allow for direct mechanical connection through anchor bars and fasteners, eliminating the need for mortar while providing superior structural strength and faster build speeds through simplified assembly operations.
4Productivity
If unitized post tension systems are used for horizontal decks and grade beams, then build speed is improved, but adaptability to quasi-marsh areas worsens due to spanning requirements
Solution Approach 1:
The patent applies dynamics by designing the block system with adjustable and reconfigurable connection features. The anchor bars and fastener systems can be configured to accommodate varying span requirements and settlement conditions typical of quasi-marsh areas. This dynamic adaptability allows the unitized system to maintain its build speed advantages while being flexible enough to handle the specific structural requirements of soft ground conditions.
Solution Approach 2:
The patent utilizes parameter changes by allowing modification of the block assembly parameters (such as anchor bar length, fastener configuration, and block arrangement) to adapt to different site conditions including quasi-marsh areas. This enables the standardized unitized system to be adjusted for specific structural requirements while maintaining the speed benefits of pre-fabricated components.
