Treatment Compartment Layout for Gravity Unloading of Loose Products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for treating loose products, such as washing and sterilization machines, face issues with blockages and accumulation of products during loading and unloading, as well as the risk of products escaping during the treatment process, particularly in machines where both operations occur on the same side.
Innovation Solution
A containing device with a treatment compartment featuring two flat lateral walls connected by a bottom wall and an open side for loading and unloading, equipped with rotation pins for the doors, allowing for efficient loading and unloading without obstacles, ensuring products can be conveyed by gravity to an unloading zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If machines treat loose products with loading and unloading on the same side to achieve compact design, then space efficiency is improved, but blockages and accumulation of products occur during loading and unloading
Solution Approach 1:
The containing device incorporates a movable bottom wall that can be tilted between a horizontal position during treatment and an inclined position during unloading. This dynamic adjustment allows the same-side loading/unloading design to function reliably by using gravity to guide products into the unloading zone when the bottom is inclined, preventing blockages while maintaining compact machine footprint.
Solution Approach 2:
The invention introduces a dimensional change by tilting the bottom wall from horizontal to inclined, creating a gravitational slope that directs products toward the unloading zone. This dimensional transformation of the bottom surface resolves the blockage issue inherent in same-side loading/unloading by adding a gravitational component to product movement.
2Reliability
If angular containing sectors are used to guarantee efficient washing and sterilization, then treatment effectiveness is improved, but products accumulate in the bottom and may escape during treatment
Solution Approach 1:
The bottom wall transitions from a static angular sector design to a dynamic, adjustable surface. During treatment, it maintains a horizontal position to prevent product escape, and during unloading, it tilts to an inclined position to facilitate product discharge into the unloading zone, eliminating accumulation problems while preserving treatment effectiveness.
Solution Approach 2:
The containing device features different local configurations: a horizontal bottom during treatment to prevent escape, and an inclined bottom during unloading to prevent accumulation. This local quality variation in the bottom wall's orientation addresses different functional requirements at different operational stages.
3Ease of manufacture
If conventional containing devices are used in same-side loading/unloading machines, then manufacturing simplicity is maintained, but products remain trapped in containers and cannot be efficiently unloaded
Solution Approach 1:
The containing device incorporates a movable bottom wall that tilts during unloading, creating a gravity-driven discharge path. This simple mechanical movement dramatically improves unloading efficiency by enabling products to slide into the unloading zone, while maintaining manufacturing simplicity through the use of basic hinge and spring mechanisms.
Solution Approach 2:
The unloading mechanism utilizes gravity itself to perform the work of product discharge. When the bottom wall is tilted, products automatically slide into the unloading zone without requiring additional mechanical force or complex actuation systems, achieving high productivity with minimal complexity.
