Grease Ejection Tip With Scraping Surface for Narrow-Space Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ejection devices fail to effectively remove foreign matter such as mud, dust, or dirt from relevant portions, leading to grease contamination when supplying grease to these areas.
Innovation Solution
An ejection device with an insertion portion featuring a foreign matter removing surface on its distal end, which can be operated to scrape off adhering foreign matter by withdrawing, inserting, or swinging the insertion portion, and optionally includes a projecting portion and an imaging device for precise operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an insertion portion is used to supply grease to a relevant portion in a narrow space, then grease can be delivered to the target area, but foreign matter cannot be removed and grease contaminated with foreign matter is supplied
Solution Approach 1:
The patent combines the grease ejection function and foreign matter removal function into a single insertion portion. The distal end portion includes both a fluidic substance ejection port for grease supply and a foreign matter removing surface for scraping off contaminants, allowing both functions to be performed by one tool without requiring separate devices.
Solution Approach 2:
The foreign matter removing surface is positioned at the distal end portion of the insertion portion, enabling foreign matter to be removed before grease is supplied. This preliminary cleaning action ensures that the grease is applied to a clean surface, preventing contamination that would occur if grease were applied first.
2Ease of operation
If the insertion portion is made simple for easy operation, then it can be easily handled, but it lacks the capability to remove foreign matter
Solution Approach 1:
The patent integrates multiple functions (grease ejection and foreign matter removal) into a single insertion portion structure. By combining these functions in one tool rather than requiring separate tools, the device maintains ease of operation while gaining enhanced versatility and adaptability for different maintenance needs.
Solution Approach 2:
The insertion portion is designed as a multi-functional tool that can both eject grease and remove foreign matter. This universal design allows a single device to handle multiple tasks that would otherwise require separate tools, improving adaptability without compromising operational simplicity.
3Object-affected harmful factors
If a foreign matter removing surface is added to the distal end portion, then foreign matter can be removed by scraping, but the device structure becomes more complex
Solution Approach 1:
The foreign matter removing surface is localized to only the distal end portion of the insertion portion where it is needed for scraping foreign matter. This localized approach adds the necessary functionality without requiring complex structures throughout the entire device, maintaining simplicity in non-critical areas while providing enhanced capability where required.
Solution Approach 2:
The distal end portion of the insertion portion is segmented into distinct functional zones: a fluidic substance ejection port for grease delivery and a foreign matter removing surface for scraping. This segmentation allows each component to perform its specific function efficiently without interfering with the other, achieving complex functionality through modular design.
4Area of stationary object
If the insertion portion is operated in narrow spaces, then access to relevant portions is achieved, but precise operation becomes difficult
Solution Approach 1:
The insertion portion is designed with a slender, elongated structure that allows it to extend into narrow spaces along the longitudinal dimension. The distal end portion with its ejection port and removing surface can access confined areas that would be inaccessible to bulkier tools, while the operator maintains control from the proximal end.
Solution Approach 2:
The distal end portion of the insertion portion is designed to be compact and streamlined, creating a simplified version of the full device that can navigate narrow spaces. This reduced-scale distal end maintains the essential functions (grease ejection and foreign matter removal) in a form factor suitable for confined access areas.
