Solution Overview
Problem
Planar drive devices face contamination issues on their outer shell, which complicates maintenance and requires effective cleaning methods, especially in environments demanding high cleanliness like pharmaceutical systems.
Innovation Solution
A planar drive device with a cleaning system integrated into its operational process, utilizing electromagnetic mobility to position the mover for cleaning, featuring a cleaning unit with spray elements, UV sources, and mechanical elements, allowing for efficient cleaning of the mover's underside, sides, and top, while maintaining mobility and minimizing manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mover is cleaned manually, then cleaning effectiveness is improved, but productivity is worsened due to operational interruption
Solution Approach 1:
The cleaning device enables the mover to clean itself automatically during transport between work areas. The cleaning unit with spray elements and suction装置 performs self-cleaning without manual intervention, resolving the contradiction by making the system self-maintaining while preserving operational continuity.
Solution Approach 2:
The mover is cleaned in advance during transit between work areas, before contamination affects operational requirements. This preliminary cleaning action ensures the mover is ready for the next task without interrupting the production workflow.
2Ease of operation
If the cleaning device is integrated into the drive surface, then ease of operation is improved, but device complexity is worsened
Solution Approach 1:
The drive surface is designed with multi-functionality, serving both as the propulsion surface for movers and as the mounting platform for cleaning devices. This universal design integrates cleaning functionality into the existing drive surface structure without adding separate complex systems.
Solution Approach 2:
The cleaning device is merged with the drive surface structure, combining two functions (driving and cleaning) into a single integrated system. The cleaning unit is positioned on the drive surface to share the same spatial and structural framework.
3Manufacturing precision
If the gap between drive sections is reduced, then manufacturing precision is improved, but ease of manufacture is worsened
Solution Approach 1:
The gap width is optimized to specific parameter ranges (3-60 mm, preferably 10-30 mm) that balance manufacturing precision requirements with ease of assembly. These parameter specifications provide clear manufacturing targets that are precise enough for functional requirements but broad enough to accommodate normal manufacturing tolerances.
