Liquid Ejecting Apparatus Electrical Component Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid ejecting apparatuses, the existing configuration where the liquid storing member is mounted with the liquid ejecting head and electrical components in a holder leads to short-circuiting issues due to liquid contact with electrical components during refilling, as the liquid can spill and adhere to them.
Innovation Solution
The electrical components are positioned deviated from the filling port in the liquid ejecting apparatus, with a cover mechanism that pivots about a pivot shaft to prevent the refilling container from entering the electrical component area, ensuring the liquid does not come into contact with them during refilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the liquid storing member is disposed above the electrical components in the holder, then the size of the liquid ejecting apparatus is reduced, but liquid may spill and contact the electrical components causing short-circuiting
Solution Approach 1:
The electrical component is extracted from the vertical stacking arrangement and disposed at a position deviated from the filling port in plan view, separating it from the potential liquid spill path while maintaining compact overall apparatus dimensions
Solution Approach 2:
The electrical component positioning transitions from a vertical arrangement (above the liquid ejecting head) to a horizontal deviation arrangement, changing the spatial dimension of protection from vertical stacking to horizontal separation, thereby preventing liquid contact while maintaining compact size
2Ease of operation
If the filling port is positioned for easy refilling, then ease of operation is improved, but the risk of liquid spilling onto electrical components increases
Solution Approach 1:
The filling port is positioned in a specific location on the liquid storing member that provides easy access for refilling operations, while the electrical component is positioned in a different local area that is deviated from this filling path, creating zone-based functional separation
