Side-Port Ejection Pipe for Lateral Grease Supply in Narrow Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ejection devices are unable to supply fluidic substances, such as grease, in a direction crossing the insertion direction, limiting their applicability in certain applications.
Innovation Solution
The ejection device incorporates an insertion portion with an ejection unit that includes a fluidic substance supply pipe with ejection ports on its side surface, allowing the fluidic substance to be ejected and supplied in a direction perpendicular to the insertion direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ejection device uses a conventional insertion portion with ejection at the distal end, then the structure is simple and easy to manufacture, but the fluidic substance cannot be supplied in a direction crossing the insertion direction
Solution Approach 1:
The ejection ports are positioned on the side surface of the distal end portion rather than at the tip, changing the ejection direction from axial to lateral. This dimensional change enables the fluidic substance to be supplied in a direction crossing the insertion direction, resolving the contradiction between supply direction versatility and structural simplicity.
2Adaptability or versatility
If the ejection device provides multiple ejection ports on the side surface, then the fluidic substance can be supplied to multiple locations, but the manufacturing precision requirements increase
Solution Approach 1:
The ejection function is segmented into multiple discrete ports positioned at different locations on the side surface of the distal end portion. Each port can be independently positioned and manufactured, allowing flexible supply to multiple locations while maintaining manageable manufacturing precision requirements through modular design.

AI summary
An ejection device includes an insertion portion that is held by an operator and inserted toward a relevant portion in a narrow space. The insertion portion includes an ejection unit that is a fluidic substance supply pipe of which distal end portion is closed. A side surface of the distal end portion of the ejection unit includes at least one fluidic substance ejection port that extends from an outer peripheral surface to an inner peripheral surface of the distal end portion and from which a fluidic substance to be supplied through the ejection unit is ejected.
