Solution Overview
Problem
Processing machines with load-bearing parts made of concrete suffer from dimensional inaccuracies due to shrinkage deformation, and existing solutions are costly and complex, failing to provide a simple and inexpensive design with minimal dimensional deviations.
Innovation Solution
A method for producing a processing machine with a load-bearing machine part made of concrete having a water-binding average value of at most 0.30, combined with high flexural strength and optional fiber reinforcement, which minimizes shrinkage deformations and eliminates the need for additional reinforcement, allowing for a simple and cost-effective design with negligible warping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional concrete with high water-binding value is used for load-bearing machine parts, then the concrete is easy to process and inexpensive, but shrinkage deformation occurs causing dimensional inaccuracies
Solution Approach 1:
The patent applies parameter changes by optimizing the water-binding value of concrete to at most 0.30 and flexural strength to at least 15 MPa. This fundamental material parameter change eliminates shrinkage deformation without requiring complex restraining structures, directly resolving the contradiction between dimensional accuracy and construction complexity
Solution Approach 2:
The patent converts the naturally occurring shrinkage deformation (harmful effect) into a beneficial process by allowing controlled early-stage shrinkage that stabilizes the concrete structure. This eliminates subsequent warping and dimensional deviations without requiring additional holding devices, transforming the harmful shrinkage into a self-stabilizing mechanism
2Manufacturing precision
If steel frame parts are added to concrete structure to prevent warping, then dimensional accuracy is maintained, but the construction becomes complicated and costs increase
Solution Approach 1:
The patent extracts and eliminates the need for steel frame parts and other holding devices by fundamentally improving the concrete material itself. Through optimized water-binding value and flexural strength, the concrete becomes self-sufficient in maintaining dimensional accuracy, removing the unnecessary steel components and simplifying construction
Solution Approach 2:
The patent replaces expensive, complex steel reinforcement structures with simple, optimized concrete that achieves the same dimensional stability function. This substitution uses inexpensive concrete material in a optimized configuration to replace costly steel frames, achieving both cost reduction and construction simplification
3Manufacturing precision
If concrete with low water-binding value is used, then shrinkage deformation is reduced, but the concrete requires special mixing and processing procedures
Solution Approach 1:
The patent applies parameter changes by setting specific thresholds for water-binding value (at most 0.30) and flexural strength (at least 15 MPa). These standardized parameters simplify the manufacturing process by providing clear material specifications that guide concrete mixing and processing, eliminating the need for complex or specialized procedures while ensuring shrinkage control
