Telescopic Flushing Assembly for Outboard Motors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outboard motor flushing systems are overly complex, difficult to operate, and cannot be easily installed from various positions due to rigid and heavy extension members, making it challenging to attach and detach the earmuff flushing device, especially in saltwater environments where corrosion is a significant concern.
Innovation Solution
A telescopically adjustable motor flushing assembly with a flexible earmuff flushing accessory that uses alternate tubular end connectors, such as straight and 90-degree connectors, to allow for easy positioning and attachment from different angles, eliminating the need for separate hoses and providing a simple, compact, and lightweight design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If rigid extension members are used to support the earmuff flushing device, then the device can reach the inlet ports from a distance, but the device becomes heavy and difficult to operate and position
Solution Approach 1:
The patent replaces rigid extension members with a telescopic boom that can extend and retract. This dynamic structure allows the flushing device to reach inlet ports at various distances while remaining lightweight and easy to position. The telescopic mechanism enables the user to adjust the length of the boom to match the specific distance required, eliminating the need for heavy rigid extensions.
2Stability of the object's composition
If the flushing device is designed with fixed structure, then it provides stable support, but it cannot be easily attached or detached from various positions
Solution Approach 1:
The telescopic boom provides a dynamic support structure that can be adjusted to various lengths and positions. This allows the earmuff flushing device to be stably supported from multiple attachment positions, including from within the boat or from the side, providing both structural stability and attachment flexibility.
Solution Approach 2:
The flushing device is divided into separable components: the telescopic boom and the earmuff flushing accessory. This segmentation allows the earmuff device to be easily attached to and detached from the boom, enabling versatile positioning while maintaining structural integrity during use.
3Adaptability or versatility
If separate hoses are used to connect water supply to the earmuff flushing device, then the system is flexible, but the device complexity increases
Solution Approach 1:
The telescopic boom is designed to integrate the water supply function directly into its structure. The boom itself serves as both the support structure and the water delivery conduit, eliminating the need for separate hoses and connections. This merging of functions reduces system complexity while maintaining the flexibility to deliver water to the earmuff device at various positions.

AI summary
A flushing device that is used to remove salt water and other corrosive agents from the cooling system of an outboard motor. The flushing device includes an earmuff flushing accessory that is attached to the end of an elongate support member and is used to create sealed chambers that surround the end ports of the motor. The elongated member can either be directly coupled to the earmuff flushing accessory or coupled through an elbow extension member to allow for the operation of the device from various positions, including to the side, in front, or from behind the outboard motor. The device is configured so that the flushing liquid flows either directly from the elongated member or through a bent extension member into the earmuff flushing accessory, thereby eliminating the need for various separate components to control the flow of the liquid. The device, therefore, uses a simple design that is both inexpensive to manufacture and effective while eliminating potential sources of failure.
