Building Material Packaging Lifting Device for Compact Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for providing building materials, such as mortar, either require significant manual labor and result in dust pollution or necessitate large investments in silos with complex logistics and high refilling costs, while also being limited in application flexibility and space usage.
Innovation Solution
A modular system comprising a packaging with a sleeve and hanging device, connected to a lifting device, and a mixing and conveying device, which allows for reduced manual work, minimized dust production, and flexible use in various spaces by positioning the packaging over the mixing device using a forklift truck with an inverted fork, enabling efficient material flow and compact system height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual emptying of sacks into a mixer is used, then low costs and simple logistics are achieved, but large amounts of manual work and severe dust pollution occur
Solution Approach 1:
The system enables self-service through automated mechanisms where the packaging device automatically positions itself over the mixer and the lifting device automatically transports packages, eliminating the need for manual emptying operations while maintaining cost-effectiveness
Solution Approach 2:
The lifting device acts as an intermediary between the packaging and the mixer, automatically transporting packages and positioning them for dumping, thereby mediating the operation to reduce manual work and dust pollution while maintaining system simplicity
2Ease of operation
If silos are used to provide building materials, then large quantities of material can be provided with little manual work, but large investments in silos and distribution centers are necessary
Solution Approach 1:
The system segments the building material storage and delivery function into individual packaging units that can be independently handled by the lifting device, eliminating the need for large silo infrastructure while maintaining automated operation
Solution Approach 2:
The system uses disposable or reusable packaging units instead of permanent silo infrastructure, achieving automated material provision with minimal investment in fixed equipment and simplified logistics
3Quantity of substance
If silos are used, then large quantities of building materials can be stored, but refilling of silos is expensive and complex
Solution Approach 1:
The system divides the material storage into discrete packaging units that can be individually refilled and replaced, simplifying the refilling process compared to large silos while maintaining adequate material storage capacity for construction projects
Solution Approach 2:
The system enables dynamic refilling of packaging units on demand rather than requiring complex refilling operations for large silos, allowing flexible and simple material replenishment while maintaining sufficient quantity for application
4Quantity of substance
If silos are used, then large quantities of building materials can be provided, but the height of silos limits setup locations to sheds or outside buildings
Solution Approach 1:
The system replaces tall silos with segmented packaging units that can be stacked to required heights, enabling material storage and provision in low-height spaces such as garages and houses while maintaining the ability to provide large quantities of material
Solution Approach 2:
The system transitions from vertical storage (tall silos) to a combination of vertical stacking of compact packages and horizontal arrangement, enabling material storage and access in low-height environments while maintaining adequate capacity
5Ease of operation
If a lifting device is used to position packaging over the mixer, then manual work is reduced and dust pollution is minimized, but the total height of the system must be kept under 230 cm
Solution Approach 1:
The lifting device provides dynamic height adjustment to position packaging units at the required height for dumping into the mixer, allowing the system to operate within the 230 cm height limit while maintaining automated operation and reducing manual work
Solution Approach 2:
The packaging units are designed as segmented, compact structures that can be efficiently handled by the lifting device, enabling automated positioning within the height constraint while minimizing manual intervention and dust pollution

AI summary
A system provides building materials including a packaging, a lifting device and a mixing and conveying device. The packaging can be positioned by the lifting device via the mixing and conveying device in such a way that a total height of the system is less than 230 cm.
