Solution Overview
Problem
Conventional hoppers are large, cumbersome, and require significant time and resources for transportation and assembly, with manual cleaning processes that disrupt industrial operations and increase operating expenses due to dust and material accumulation.
Innovation Solution
A modular hopper assembly composed of pre-fabricated units that can be easily transported and assembled, featuring an integrated auto-cleaning system using pressurized air to efficiently remove dust and debris from the interior surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional large hoppers are constructed on-site, then they can accommodate large storage capacity, but transportation and assembly time and costs increase significantly
Solution Approach 1:
The hopper is divided into multiple modular units (first hopper unit, second hopper unit, third hopper unit) that can be pre-assembled and transported separately, then quickly connected on-site. This segmentation maintains large storage capacity while reducing transportation and assembly time compared to building a single large hopper on-site.
2Ease of operation
If manual cleaning methods are used, then cleaning can be performed, but industrial process must be stopped and operating expenses increase
Solution Approach 1:
The hopper includes an automated cleaning system with cleaning members that can clean the interior surfaces without human intervention. The system can be activated to clean dust and material accumulation while the industrial process continues running, eliminating the need to stop production for manual cleaning.
3Ease of manufacture
If modular units are used, then transportation and assembly are easier and faster, but device complexity increases
Solution Approach 1:
The hopper is divided into standardized modular units with consistent connection interfaces. Each unit has a similar structure (hopper body, support members, cleaning members, outlets), making them easy to manufacture and assemble. The segmentation into repeating modules simplifies the manufacturing process despite the overall system complexity.
Solution Approach 2:
Multiple functional components are integrated into each modular unit: hopper body for storage, support members for structural integrity, cleaning members for maintenance, and outlets for material discharge. This merging of functions within standardized modules improves ease of manufacture and assembly while managing device complexity.
