Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing viscous material supply devices face challenges in efficiently removing adhered viscous material from the piston, particularly when switching between containers, leading to operational inefficiencies.
Innovation Solution
The proposed solution involves a viscous material supply device that includes a tank, a piston with a pressing surface and suction passage, and a covering sheet with a covering part and communication hole. The covering sheet is attached to the piston, covering the pressing surface and communicating with the suction passage, facilitating the removal of adhered viscous material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the piston is used to force-feed viscous material from the container, then the viscous material can be supplied efficiently, but the viscous material adheres to the piston making removal difficult
Solution Approach 1:
A sheet is introduced as an intermediary component between the piston and the viscous material. The sheet contacts the viscous material during force-feeding while the piston contacts the sheet, preventing direct adhesion between the piston and viscous material. This mediator approach resolves the contradiction by maintaining supply efficiency while enabling easy removal through simple sheet detachment.
2Quantity of substance
If the piston is temporarily removed from the container to supplement viscous material, then the container can be refilled, but the adhered viscous material on the piston must be removed first
Solution Approach 1:
The sheet serves as a mediator that prevents viscous material adhesion to the piston during storage and force-feeding operations. When the container needs refilling, the piston with the attached sheet can be removed without requiring time-consuming cleaning operations, as the sheet can be easily detached and replaced.
3Ease of operation
If the covering sheet is attached to cover the pressing surface, then viscous material adhesion to piston is prevented, but the device structure becomes more complex
Solution Approach 1:
A thin sheet is used to cover the pressing surface of the piston. This flexible film approach provides effective coverage to prevent viscous material adhesion while adding minimal structural complexity. The sheet can be made from simple materials and attached in straightforward ways, maintaining ease of operation without significantly complicating the device structure.
