Gapless Buffer Shoe Assembly for Masonry Block Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Masonry block manufacturing often results in undesirable dimensional variations and cracks due to the mounting of shoes in molds, leading to uneven pallet stacks and other unwanted characteristics.
Innovation Solution
The use of a shoe assembly with buffers and snubbers between the shoe and a backup plate, where the relaxed height of the buffers is equal to or less than the snubbers, providing flexibility to prevent upward displacement and formation of cracks while maintaining uniform block height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If shoes are mounted rigidly in molds, then structural stability is improved, but dimensional variations and cracks occur
Solution Approach 1:
The patent changes the physical state of the support structure from rigid to flexible by introducing buffers and snubbers. These components allow controlled deformation during the tamping process, enabling the shoe to adapt to variations in masonry mix consistency while maintaining overall structural stability and preventing cracks.
Solution Approach 2:
The support structure is transformed from a static rigid mounting to a dynamic flexible system. The buffers and snubbers provide motion absorption, allowing the shoe to move slightly in response to changing conditions during block formation, thereby eliminating dimensional variations while maintaining stability.
2Stability of the object's composition
If rigid support is used to prevent displacement, then position stability is improved, but spider cracks form
Solution Approach 1:
The patent applies beforehand cushioning by placing buffers and snubbers between the shoe and backup plate to absorb impact and stress before cracks can form. These cushioning elements prevent the transmission of excessive forces that would cause spider cracks while maintaining position stability during the tamping process.
Solution Approach 2:
The buffers and snubbers serve as intermediary elements between the rigid shoe and backup plate. They mediate the mechanical stress, allowing controlled deformation that prevents crack formation while maintaining overall position stability of the shoe assembly.
3Object-generated harmful factors
If flexible mounting is used to prevent cracks, then crack prevention is improved, but dimensional accuracy deteriorates
Solution Approach 1:
The patent applies local quality by providing flexibility only where needed (at the shoe-support interface) while maintaining rigidity elsewhere. The buffers and snubbers are strategically positioned to provide localized compliance that prevents cracks without compromising the overall dimensional accuracy of the manufactured block.
