Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction of concrete foundations for freestanding objects like parasols and lampposts is complex, time-consuming, and prone to errors, requiring specialized expertise and individual design, which increases costs and can compromise durability and load-bearing capacity, especially in constrained spaces.
Innovation Solution
A construction unit comprising a sheet metal outer frame with integrated reinforcing bars, serving as permanent formwork, which is pre-configured for easy assembly on-site, eliminating the need for separate formwork and reinforcement, and allowing for standardized production of foundations with mechanical stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional formwork and reinforcement methods are used for concrete foundation construction, then the foundation can achieve required structural integrity, but the construction process becomes complex, time-consuming, and error-prone
Solution Approach 1:
The patent combines the formwork and reinforcement functions into a single integrated construction unit. The sheet metal outer frame serves as permanent formwork while reinforcing bars are pre-attached to the frame, merging two separate construction tasks (formwork installation and reinforcement placement) into one unified component that is installed as a single unit.
Solution Approach 2:
The construction unit is pre-configured off-site with reinforcing bars already attached to the outer frame in the correct positions and orientations. This preliminary assembly of reinforcement and formwork before transport to the construction site eliminates on-site errors in reinforcement placement and reduces construction time while maintaining structural integrity.
2Reliability
If individual design and specialized expertise are used for each concrete foundation, then the foundation quality and durability are improved, but construction costs and time increase
Solution Approach 1:
The construction unit is designed as a universal, standardized component that can be used for various foundation applications. The same basic design with sheet metal outer frame and pre-attached reinforcing bars can serve multiple purposes across different construction projects, eliminating the need for individual custom design while maintaining quality through standardized manufacturing processes.
Solution Approach 2:
Instead of creating unique designs for each foundation, the patent uses replicated standardized construction units that can be manufactured in advance and deployed repeatedly. This copying approach maintains consistent quality across multiple installations while significantly improving construction speed and reducing costs.
3Manufacturing precision
If traditional formwork methods are used, then the foundation can be constructed with proper reinforcement, but the excavations must be larger and more space is required on the construction site
Solution Approach 1:
By merging the reinforcement bars with the outer frame into a single integrated unit, the construction requires smaller excavations because the reinforcement is already positioned within the formwork boundaries. This eliminates the need for additional space that would be required for separate reinforcement installation and ensures precise reinforcement placement without requiring larger excavation areas.
4Reliability
If conventional construction methods are used, then the foundation can be built with proper formwork and reinforcement, but the process requires more time and increases construction costs
Solution Approach 1:
The construction unit is prepared in advance with reinforcing bars attached to the outer frame in the correct configurations. This preliminary assembly ensures that when the unit is installed on-site, both formwork and reinforcement are already in place, eliminating time-consuming on-site tasks while maintaining the load-bearing capacity through pre-verifiable reinforcement placement.
Solution Approach 2:
By combining formwork and reinforcement into one integrated unit that is installed as a single component, the patent reduces the number of construction steps required. This merging eliminates the sequential time requirements for separate formwork installation, reinforcement placement, and securing operations, significantly reducing construction time while ensuring proper load-bearing capacity through integrated design.

AI summary
A construction unit for producing a concrete foundation, in particular for a parasol, a use of a construction unit for producing a concrete foundation, and a method for producing a concrete foundation. A construction unit (1) for producing a concrete foundation, in particular for a parasol, comprises an outer frame (10) made of sheet metal, which serves as permanent formwork for concrete to be poured into the outer frame (10). The construction unit further comprises several reinforcing bars (20) arranged inside the outer frame (10). A first end (21) of each reinforcing bar (20) is attached to a first region (11) of the outer frame (10), and a second end (22) of the reinforcing bar (20), opposite the first end (21), is attached to a second region (12) of the outer frame (10). The construction unit can be pre-configured and supplied cost-effectively, ready for use on the construction site.The construction unit prevents errors during construction and increases the quality of the manufactured concrete foundations.
