Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coolant draining devices for internal combustion engines often result in spilling, posing a slipping hazard and inefficiency in fluid collection.
Innovation Solution
A pipe attachable to the engine's coolant drain, equipped with a valve and a telescopically adjustable hose, allowing controlled flow and routing of coolant into a receptacle without spilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional rigid drain pipe is used, then the structure is simple and easy to manufacture, but the coolant spills during draining operations
Solution Approach 1:
The patent applies the dynamics principle by making the hose telescopic and adjustable in length, allowing it to adapt to different draining scenarios. The hose can extend or retract as needed, providing flexibility to reach the drain port accurately without spilling, while maintaining relatively simple construction through the use of a collapsible hose mechanism rather than complex rigid piping systems.
2Adaptability or versatility
If a fixed-length hose is used, then the device structure is simple, but the hose cannot be properly routed into the receptacle for various engine positions
Solution Approach 1:
The telescopic hose mechanism allows the hose length to dynamically adjust based on the distance between the drain port and receptacle. This enables proper routing for various engine positions and orientations without requiring multiple hose lengths or complex extension mechanisms, achieving versatility through a single dynamic component.
Solution Approach 2:
The telescopic hose employs a nested structure where one hose section is inserted within another, allowing compact storage when retracted and extended length when needed. This nesting mechanism provides adjustable length capability without adding significant complexity to the overall device structure.
3Reliability
If the valve is always open for draining, then the draining operation is simple and fast, but the coolant spills outside the receptacle
Solution Approach 1:
The valve mechanism allows the operator to preliminarily position the hose tip inside the receptacle and adjust the hose length before opening the valve. This preliminary positioning ensures that when the valve is opened for draining, the coolant flows directly into the receptacle without spilling, combining controlled flow with operational simplicity through proper sequencing of actions.

AI summary
An engine coolant draining device for draining fluid coolant from an internal combustion engine includes a pipe which is attachable to a coolant drain on an internal combustion engine to receive a fluid coolant from the coolant drain. A valve is in fluid communication with the pipe to enable the fluid coolant to flow through the valve. The valve is positionable in a closed condition or an open condition thereby inhibiting or enabling the fluid coolant to flow through the valve. A hose is in fluid communication with the valve to receive the fluid coolant from the valve. The hose has a telescopically adjustable length thereby enabling the hose to be routed to a fluid receptacle for collecting the fluid coolant in the fluid receptacle without spilling.
