Oil Suction Device Segmented Sleeve Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oil-refilling devices are prone to slipping due to oil contamination, leading to spills and contamination of the oil, and users struggle to distinguish between different types of oils, often resulting in incorrect oil being added to a vehicle.
Innovation Solution
An oil suction device with a main body and a sleeve member, featuring a flow hole, receiving space, and hollow-out portions for grip and visibility, where the sleeve member and main body are in different colors to facilitate easy identification of oil types and prevent slipping, and are made of lightweight materials for cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the tube body is made of metal with a smooth surface, then the manufacturing precision and durability are improved, but the ease of operation deteriorates because the smooth surface becomes slippery when contaminated by oil
Solution Approach 1:
The device is divided into two distinct parts: a metal tube body for maintaining manufacturing precision and durability, and a separate sleeve member with a rough outer surface for providing grip firmness. The sleeve member is disposed on the tube body, creating a segmented structure where each component fulfills its specific function without compromising the other.
Solution Approach 2:
Different parts of the device have different surface qualities tailored to their specific functions. The tube body maintains a smooth surface for manufacturing precision and oil flow, while the sleeve member has a rough outer surface specifically at the gripping area to provide friction and prevent slipping when contaminated by oil.
2Strength
If the tube body is made of metal, then the strength and durability are improved, but the weight of the device increases
Solution Approach 1:
The device uses a composite structure combining metal and plastic materials. The metal tube body provides structural strength and durability, while the plastic sleeve member reduces the overall weight of the device. This composite approach allows the device to maintain necessary strength while being lighter and more cost-effective than a fully metal construction.
3Adaptability or versatility
If multiple oil-refilling devices are prepared for different oil types, then the adaptability is improved, but the device complexity increases and users cannot easily distinguish between them
Solution Approach 1:
The sleeve member is provided in different colors corresponding to different types of oil (e.g., blue for engine oil, red for brake oil, green for coolant). This color-coding system allows users to easily distinguish between different oil types and select the appropriate device, eliminating the need to remember which device contains which oil and preventing mistakes.
4Manufacturing precision
If the tube body has a smooth surface, then the manufacturing precision is improved, but the object-affected harmful factors increase because oil contamination causes slipping and potential spills
Solution Approach 1:
The device is divided into two distinct parts: a metal tube body for maintaining manufacturing precision and durability, and a separate sleeve member with a rough outer surface for providing grip firmness. The sleeve member is disposed on the tube body, creating a segmented structure where each component fulfills its specific function without compromising the other.
Solution Approach 2:
The sleeve member acts as an intermediary between the user's hand and the oil-contaminated tube body. It provides a rough, high-friction surface that resists slipping even when oil is present, while the tube body maintains its smooth surface for proper oil flow and manufacturing precision. The intermediary sleeve protects against the harmful effect of oil contamination.

AI summary
An oil suction device is provided, including a main body and a sleeve member. A front end of the main body has a flow hole, an interior of the main body has a receiving space, one of two ends of a piston member is disposed in the receiving space and movable relative to the main body to allow a fluid to flow into or out of the receiving space through the flow hole, and the main body is light-penetrable. The sleeve member covers the main body, the sleeve member has at least one hollow-out portion formed radially, and the sleeve member and the main body are in different colors.
