Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mold systems for pouring concrete lack effective quality management, particularly in ensuring uniformity and preventing bleeding, as they rely on indirect methods such as air outlets for airtightness checks and do not efficiently manage pouring pressure.
Innovation Solution
A self-pouring mold system with a pouring pipe that passes through the mold from the rear to the front, utilizing a concrete pumping apparatus and a self-pouring apparatus with a horizontal and vertical pouring finishing plate system to lift the pouring pipe and ensure uniform concrete distribution without bleeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If concrete is poured through upper openings of molds, then pouring is simple and direct, but bleeding occurs and uniformity of material cannot be ensured
Solution Approach 1:
The patent inverts the conventional pouring approach by pouring concrete from the rear side of the mold toward the front side, rather than from the upper opening downward. This reverse pouring method allows concrete to be injected from below, preventing bleeding while ensuring uniform material distribution throughout the mold cavity.
Solution Approach 2:
The patent changes the pouring dimension from vertical (upper to lower) to horizontal (rear to front), introducing a new spatial dimension for concrete injection. This dimensional change enables better control over concrete flow and pressure distribution, eliminating bleeding while maintaining material uniformity.
2Adaptability or versatility
If concrete is poured toward sides of molds, then upper opening interference is avoided, but airtightness cannot be visually checked and quality management becomes difficult
Solution Approach 1:
The patent incorporates a feedback mechanism by including a vent hole that allows air to escape during pouring from the rear side. The emergence of air from the vent hole provides visual feedback confirming that the mold is properly sealed and airtight, enabling quality verification without direct visual inspection of the pouring interface.
Solution Approach 2:
The patent introduces a vent hole as an intermediary element that mediates between the concrete pouring process and quality verification. The vent hole serves as an indirect indicator of airtightness, allowing operators to confirm proper sealing through air escape observation rather than direct inspection of the concrete-mold interface.
3Reliability
If pouring pressure is increased to ensure airtightness, then concrete fills the mold more completely, but bleeding increases and material uniformity deteriorates
Solution Approach 1:
The patent changes the pouring pressure parameter by injecting concrete from the rear side at controlled pressure levels. This pressure control method ensures complete mold filling and airtightness while preventing excessive pressure that would cause bleeding, thereby maintaining material uniformity through optimized pressure parameters.

AI summary
The present invention relates to a self-pouring mold system which ensures uniformity of a material by laterally pouring concrete into a mold installed on a side of a wall structure and minimizing a fall head generated when the concrete is poured to prevent bleeding, thereby ensuring uniformity of a fire-proofing material and adjusting a required fire-proofing coating thickness, and a method of fire-proofing, repairing, and reinforcing using the same.
