Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular concrete block molds with multiple parts face challenges in efficient repair and adaptation due to wear and defects, requiring costly and time-consuming replacement or modification processes, especially when production circumstances change.
Innovation Solution
The method employs additive manufacturing, specifically 3D metal printing, to create replacement or adapted mold parts that can be decentralized and manufactured on-site, allowing for quick repair and modification of mold parts without the need for traditional tools or extensive shipping, enabling the use of metal parts with improved topology and reduced weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional machining or casting processes are used to manufacture replacement mold parts, then manufacturing precision and reliability are maintained, but production time and cost increase
Solution Approach 1:
The patent changes the manufacturing method from conventional machining/casting to additive manufacturing, fundamentally altering the production parameters. This enables rapid fabrication of replacement mold parts while maintaining the required precision through controlled deposition processes, directly resolving the time-cost tradeoff in mold repair operations
2Reliability
If entire concrete block molds are replaced due to wear or defects, then reliability is maintained, but cost and resource waste increase
Solution Approach 1:
The patent applies segmentation by dividing the mold system into replaceable individual parts. Instead of replacing the entire concrete block mold when one part becomes defective or worn, only the specific affected component needs to be manufactured and replaced using additive manufacturing, thereby maintaining overall mold reliability while minimizing material waste
Solution Approach 2:
The patent enables recovery of functional mold parts by selectively replacing only the defective segments. The intact portions of the mold are retained and reused, recovering valuable materials and reducing the need for complete mold replacement, which aligns with sustainable manufacturing practices
3Strength
If mold parts are permanently welded, then structural integrity is maintained, but adaptability and repairability decrease
Solution Approach 1:
The patent introduces dynamics to the previously static, permanently welded mold structure. By using detachable connections and additive manufacturing for replacement parts, the mold system becomes dynamically reconfigurable, allowing parts to be removed, replaced, or modified without permanent joining, thus enhancing adaptability while maintaining structural integrity through proper connection design
4Manufacturing precision
If centralized manufacturing facilities are used for mold parts, then manufacturing precision is maintained, but transportation cost and time increase
Solution Approach 1:
The patent enables self-service manufacturing at the point of need. Additive manufacturing equipment can be deployed locally at construction sites or maintenance facilities, allowing mold parts to be manufactured on-demand without requiring centralized production facilities and subsequent transportation. This eliminates transportation energy consumption while maintaining manufacturing precision through controlled additive processes

AI summary
In a method for repairing or modifying a modular concrete block mold having multiple mold parts, a replacement mold part for a mold part to be replaced of the concrete block mold is additively manufactured and the replacement mold part is installed in the concrete block mold in place of the mold part to be replaced, or a region of a mold part to be adapted of the concrete block mold is additively manufactured and the mold part adapted in this way is then installed in the concrete block mold.
