Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oil filling devices are not adjustable and thus cannot accommodate various models and types of engines, leading to issues like over-filling, spillage, and air bubbles in the oil tube, causing inefficiency and environmental pollution.
Innovation Solution
An oil filling device with an extendable tube assembly and direction adjustment mechanism, allowing for adjustable direction and distance between the oil filling funnel and the engine oil filling hole, enabling smooth oil filling across different engine models and types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional non-adjustable oil filling devices are used, then the device structure is simple, but the device cannot accommodate various models and types of engines with different oil filling hole locations and directions
Solution Approach 1:
The patent applies the dynamics principle by making the tube assembly extendable and the connection assembly rotatable. The tube can extend or retract to adjust length, and the connection assembly can rotate to adjust the angle, transforming a static fixed-structure device into a dynamic adjustable one that adapts to different engine oil filling hole positions and directions.
Solution Approach 2:
The patent implements universality by designing a single oil filling device that can serve multiple engine models and types. Through the extendable tube assembly and rotatable connection assembly, one device can accommodate various oil filling hole locations and directions, eliminating the need for multiple specialized devices for different engine models.
2Reliability
If the oil filling funnel is fixed in position, then the device structure is simple, but over-filling and spillage occur when the oil filling hole location varies
Solution Approach 1:
The extendable tube assembly with extension and retraction capability allows the oil filling funnel to dynamically adjust its position and distance from the oil filling hole. This dynamic adjustment ensures the funnel can be precisely positioned for different engine models, preventing over-filling and spillage while maintaining reliable oil filling operation.
3Length of moving object
If a fixed-length tube is used, then the device structure is simple, but the oil filling funnel cannot be moved toward or away from the oil filling hole for different engine heights
Solution Approach 1:
The tube assembly is designed as an extendable dynamic structure that can increase or decrease its length. This allows the oil filling funnel to be moved toward or away from the oil filling hole according to different engine heights and positions, solving the limitation of fixed-length tubes while accommodating various engine configurations.
Solution Approach 2:
The extendable tube assembly likely employs a telescopic structure where one tube is nested within another, allowing the tube to extend or retract by sliding sections relative to each other. This nesting arrangement enables length adjustment while maintaining a compact form when retracted.
4Adaptability or versatility
If non-adjustable oil filling devices are used for different engine models, then each device is simple, but multiple devices are needed which is troublesome
Solution Approach 1:
The patent creates a universal oil filling device that can be used across multiple engine models and types. The extendable tube assembly and rotatable connection assembly enable a single device to adapt to various oil filling hole positions and directions, eliminating the need to change devices when working with different engine models and greatly improving operational convenience.

AI summary
An oil filling device includes an oil filling funnel, an extendable tube assembly, a direction adjustment assembly, and a coupling assembly. The oil filling funnel is mounted to a first end of the extendable tube assembly. The extendable tube assembly has a second end mounted to the direction adjustment assembly. The direction adjustment assembly is mounted to the coupling assembly that is attachable to an oil filling hole of an engine. The direction adjustment assembly enables adjustment of the direction of the extendable tube assembly and the oil filling funnel with respect to the engine, while the extendable tube assembly allows the oil filling funnel to be selectively moved toward or away from the oil filling hole. Thus, the oil filling device may accommodate various heights and angles of oil filling hole of engine and allows filling of oil into the engine to be conducted in a smoother manner.
