Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coating apparatuses used for coating loose materials like seeds suffer from slow, cumbersome, and dangerous methods for removing build-up, which leads to inefficiencies and increased costs.
Innovation Solution
A cleaning arrangement for a coating apparatus that includes a base-scraping arrangement and a mounting arrangement to reversibly lower the base-scraping arrangement from a coating position to a scraping position, allowing for efficient removal of build-up from the base and walls of the apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hand tools like chisels are used to remove build-up, then the build-up can be removed, but the process becomes slow and expensive
Solution Approach 1:
The base-scraping arrangement is designed to be automatically positioned against the base by the base's own rotation. As the base rotates, it automatically feeds the build-up against the scraping arrangement, eliminating the need for manual intervention and enabling continuous, high-speed cleaning without requiring external power sources or complex positioning mechanisms.
Solution Approach 2:
The invention replaces the manual mechanical system of hand-held chisels with an automated scraping system. The scraping arrangement includes a scraping element that mechanically engages with the build-up on the base, using the base's rotation to generate the necessary force and motion for effective removal, thereby eliminating slow manual labor.
2Ease of operation
If hand tools are used for cleaning, then build-up removal is possible, but the process becomes cumbersome and dangerous
Solution Approach 1:
The system eliminates the need for operators to manually handle dangerous cleaning tasks. The automated scraping arrangement performs the hazardous work of removing build-up without human intervention, thereby eliminating safety hazards associated with hand tools while improving ease of operation through simple automated control.
Solution Approach 2:
The scraping arrangement acts as an intermediary between the base and the build-up removal process. It mediates the dangerous interaction by providing a controlled, automated mechanism that safely engages with the build-up and removes it without requiring direct human contact with hazardous materials or moving parts.
3Productivity
If periodic manual cleaning is performed, then build-up is removed, but production efficiency decreases
Solution Approach 1:
The scraping arrangement enables continuous cleaning action during base rotation without interrupting the coating process. The system maintains constant contact between the scraping element and the build-up, ensuring uninterrupted removal throughout the operational cycle, thereby eliminating downtime and maximizing production efficiency.
Solution Approach 2:
The scraping arrangement is positioned to engage with build-up as it forms on the base, performing preliminary cleaning before the build-up becomes problematic. This proactive approach prevents excessive accumulation that would require lengthy manual intervention, thereby maintaining continuous production flow.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cleaning arrangement significantly improves the efficiency and safety of the coating process by quickly and effectively removing build-up, thereby increasing output by up to 50% and reducing operational costs.
Implementation Method 1
a base-scraping arrangement... positioned to scrape build-up from the base
Implementation Method 2
the base-scraping arrangement is shaped for build-up scraped from the base to be driven, by rotation of the base, outwardly along the base-scraping arrangement
Implementation Method 3
a wall-scraping arrangement configured to rotate within the space to scrape build-up from the wall arrangement
Implementation Method 4
the wall-scraping arrangement may include one or more portions for contacting the build-up and mounted adjustably to enable a clearance to the wall arrangement to be adjusted
