Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete shaping inserts have complex production processes due to the need for custom-made two- or three-dimensional lattice works to hold displacement bodies in place, making them difficult to produce simply and flexibly, especially on construction sites.
Innovation Solution
A concrete shaping insert design featuring displacement bodies with interstitial tubes and connecting components that allow for easy assembly using standard reinforcement parts, such as reinforcing bars, without the need for specialized tools or lattice works, enabling flexible and cost-effective production on-site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If custom-made two- or three-dimensional lattice works are used to hold displacement bodies, then the displacement bodies are securely fixed in position, but the production process becomes very complex and difficult to manufacture
Solution Approach 1:
The lattice work is divided into multiple individual lattices (first lattice and second lattice) that are arranged parallel to each other. Each lattice independently holds displacement bodies through its own threading devices, eliminating the need for a single complex three-dimensional lattice structure while maintaining fixing stability.
Solution Approach 2:
The individual lattices are designed with universal threading devices that can accommodate various displacement bodies (hollow plastic balls, plastic balls, or plastic half-covers) of different sizes and shapes. This standardized design simplifies manufacturing while maintaining reliable fixation across different applications.
2Reliability
If complex lattice works are used to arrange displacement bodies, then the displacement bodies are held securely, but the production cost and manufacturing difficulty increase significantly
Solution Approach 1:
The structure is segmented into multiple simple parallel lattices rather than one complex lattice. Each lattice is easier to manufacture individually, and they can be produced using standard fabrication processes, significantly reducing production complexity and cost while maintaining secure fixation.
Solution Approach 2:
Instead of creating a unique complex lattice design, the invention uses replicated simple lattice structures. Each lattice is a copy of the same standardized design with identical threading devices, allowing for efficient manufacturing through repetition and standardization.
3Ease of manufacture
If standard reinforcement parts are used instead of custom lattice works, then production becomes simpler and more flexible, but the ability to securely hold displacement bodies may be compromised
Solution Approach 1:
The lattices are designed with universal threading devices that work with various types of displacement bodies. This standardized interface ensures reliable fixation while allowing the use of simple, easily manufactured lattice structures that can be produced with standard reinforcement parts.
Solution Approach 2:
The threading devices act as intermediary elements between the simple lattice structure and the displacement bodies. They provide the mechanical engagement needed for secure fixation while allowing the lattice itself to remain a simple, easily manufactured structure.

AI summary
The invention relates to a concrete shaping insert, which is formed to be arranged in a formwork mold before a concreting process, comprising a first and second fixing element, between which at least one displacement body is arranged. The concrete shaping insert is characterized in that, the displacement body has an interstitial tube and that the first and second fixing element are connected to one another with at least one connecting component, which proceed through the interstitial tube.
