Granulate Portioning Module for Easier Electric Drive Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing granulate portioning means lack modularity and universality, necessitating separate servicing or repair of the electric drive device, and do not allow for conversion between portioning and band placement configurations without disassembly.
Innovation Solution
The electric drive device and portioning rotor are integrated into a removable module that can be detached non-destructively and reversibly, with the module including a housing cover and bearing, allowing for easy maintenance and conversion to a band placement configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the electric drive device is integrated permanently into the housing, then the structural stability is improved, but the ease of repair and maintenance deteriorates
Solution Approach 1:
The granulate portioning means is divided into modular components: a housing main body and a removable portioning module. The portioning module contains the portioning rotor and is detachably connected to the housing main body, allowing the electric drive device to be integrated with the portioning module while maintaining overall system stability. This segmentation enables the drive device to be serviced by simply removing the portioning module without disassembling the entire housing structure.
2Ease of operation
If the portioning rotor is loosely secured in the housing, then the ease of operation is improved, but the reliability deteriorates due to risk of detachment
Solution Approach 1:
The portioning module employs asymmetric securing mechanisms including a retention protrusion on the module that engages with a corresponding retention recess in the housing main body, combined with a retention element that locks in a specific orientation. This asymmetric design provides reliable prevention of detachment while maintaining ease of operation through simple modular removal and reattachment.
3Stability of the object's composition
If a complex disassembly procedure is used to service the electric drive device, then the structural integrity is maintained, but the loss of time increases
Solution Approach 1:
The portioning module is pre-assembled as a complete serviceable unit containing the portioning rotor and electric drive device. The module includes pre-configured retention elements and positioning features that enable quick attachment and detachment. This preliminary preparation allows the entire portioning module to be removed and serviced as a single unit without complex disassembly procedures, significantly reducing maintenance time while preserving structural integrity through proper retention mechanisms.
