Modular Mold System for Vacuum Break in Sand Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing molds for forming structures with molding substances like sand or snow often create vacuums that make it difficult to separate the mold from the formed structure, leading to potential damage or loss of structural integrity.
Innovation Solution
A modular mold system comprising separable sections that can be connected and secured using latches or buckles, allowing for denser packing and easier separation by using a separation tool to break the vacuum, enabling the creation of larger and more complex structures without damaging them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If molding substance is packed or compacted in the mold to create a sturdier structure, then the structural strength is improved, but a vacuum is created that makes mold separation difficult and may cause structure damage
Solution Approach 1:
The mold is divided into multiple separable sections that can be detached independently. This segmentation allows the mold to be separated from the molded structure in stages, making it easier to overcome the vacuum adhesion force without requiring excessive force that could damage the structure.
Solution Approach 2:
A vacuum breaking mechanism serves as an intermediary device between the user and the mold separation process. This mechanism actively breaks the vacuum seal formed during compaction, mediating the transition from a strongly adhered state to a separable state and enabling easy mold removal without structure damage.
2Manufacturing precision
If a vacuum is created inside the mold during compaction, then the molding substance is densely packed, but the vacuum may retain molding substance in the mold or cause structure breakage during separation
Solution Approach 1:
The vacuum breaking mechanism is activated before the mold separation process begins. This preliminary action eliminates the harmful vacuum effect in advance, preventing potential structure breakage or material retention issues that would occur during subsequent separation operations.
Solution Approach 2:
The vacuum, which initially causes harmful adhesion and potential structure damage, is converted into a beneficial controlled release mechanism. By deliberately introducing the vacuum breaking mechanism, the system transforms the harmful vacuum retention effect into a controlled process that enables clean separation while maintaining structure integrity.
3Ease of operation
If vertically-removed molds are used to simplify separation, then gravity assists in removal, but the molds are limited to forms that taper upward and cannot create higher structural elements
Solution Approach 1:
The mold is divided into multiple sections that can be removed in different directions and at different times. This segmentation frees the design from the constraint of requiring uniform tapering, allowing creation of complex structures with varying cross-sections and higher structural elements that would be impossible with single-piece vertical removal molds.
Solution Approach 2:
The mold system transitions from a static single-piece design to a dynamic multi-section design where sections can be independently manipulated. This dynamic approach allows adaptation to various structure shapes and sizes, enabling creation of complex geometries while maintaining ease of removal through coordinated section detachment.

AI summary
Systems, methods, and articles of manufacture provide for a mold system for molding structures (e.g., sand castles) from one or more various types of molding substances (e.g., sand, clay, snow). In one embodiment, a mold system comprises a split mold comprising at least two mold sections. In one embodiment, a modular mold system allows for different types of mold sections with corresponding joining elements to be joined together to create forms for molding various types of structures. In some embodiments, mold sections are configured to facilitate the breaking of a vacuum created when molding substances are packed into the mold system, thus making it easier to separate a mold from the formed structure.
