Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional mortar production methods face challenges such as long setting times, sagging, low capacity utilization, and unstable quality, with wet mixing resulting in large batch sizes and storage needs, and dry mixing leading to material separation during transportation, necessitating a more efficient and environmentally friendly solution.
Innovation Solution
An environmental-friendly mortar robot is designed with modular container modules for cement, fly-ash, sand, and water management, incorporating spiral conveying machines, level meters, and a stirring system, allowing for on-demand mixing and production of various mortar types while occupying a small area and being easily transported.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wet mixing is used to produce large amounts of mortar, then the production capacity is improved, but the setting time becomes long and sagging occurs
Solution Approach 1:
The system segments the mixing process into multiple small batches rather than producing large amounts at once. The modular container modules (first, second, third, and fourth container modules) enable divided production, allowing mortar to be mixed in smaller quantities with shorter setting times while maintaining high overall productivity through continuous operation.
2Productivity
If wet mixing is used to produce large amounts of mortar, then the production capacity is improved, but storage space requirements increase
Solution Approach 1:
The system divides the production process into segments, mixing mortar in small batches immediately before use rather than producing large quantities for storage. The modular container modules can be positioned close to the construction site, eliminating the need for large centralized storage facilities while maintaining high production capacity.
3Volume of stationary object
If dry mixing is used for transportation, then the storage space is reduced, but material separation occurs during transportation
Solution Approach 1:
The system uses dynamic control through the air compressor system and flow-aiding devices to maintain proper material composition during transportation and mixing. These systems actively manage the flow of materials, preventing separation while enabling compact storage and transport of dry-mixed mortar components.
4Volume of stationary object
If dry mixing is used, then the storage space is reduced, but secondary stirring is required at the construction site
Solution Approach 1:
The system combines multiple functions including mixing, transportation, and material management into an integrated modular platform. The container modules are pre-configured with all necessary components (air compressor, flow-aiding devices, stirring mechanisms), allowing the system to perform secondary stirring automatically at the construction site without requiring separate operations or additional equipment.
5Device complexity
If traditional mortar production methods are used, then the equipment is simple, but the production efficiency is low
Solution Approach 1:
The modular container module system is designed with multi-functionality, where each module can perform multiple operations (storage, mixing, transportation, dispensing). This universal design enables high production efficiency through automated multi-step processes while keeping individual module complexity manageable, achieving both efficiency and reasonable complexity.
