Solution Overview

Problem

Draining fluids, such as oil, from small engines is often tedious and time-consuming due to difficulty in accessing drain ports, leading to potential spillage and mess.

Innovation Solution

A fluid drain system comprising a hose, hose cap coupler, clip, and tether that allows for easy and tool-less drainage by mounting to the engine housing, with a flexible hose and secure clip configuration to reduce spillage and improve accessibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional draining methods are used, then the drain port is accessible, but the draining process is tedious and time-consuming

Engineering Contradiction:
Improvedraining speedVSAvoidaccessibility to drain port
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

A hose with a coupler is introduced as an intermediary component between the drain port and the fluid container. The coupler attaches to the drain port, and the hose extends the reach, allowing fluid to be drained without direct access to the drain port. This mediator enables faster draining while maintaining accessibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The hose extends the draining system in a different spatial dimension, allowing the fluid container to be positioned away from the engine. This dimensional extension solves the accessibility problem by allowing draining from a remote location while maintaining high productivity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If the drain port is difficult to access, then spillage is reduced, but the draining process becomes tedious and time-consuming

Engineering Contradiction:
Improvedraining efficiencyVSAvoidspillage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The hose and coupler assembly acts as an intermediary that provides a controlled fluid pathway. The coupler creates a secure connection to the drain port, and the hose provides a contained channel for fluid flow, preventing spillage while enabling efficient draining through extended reach.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The coupler is pre-attached to the drain port before draining begins, establishing a secure, spill-proof connection in advance. The hose is pre-positioned to receive the fluid flow, ensuring that when draining starts, the fluid is immediately contained and directed, preventing spillage while maximizing draining efficiency.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If a hose and coupler system is used, then draining becomes faster and less messy, but the device complexity increases

Engineering Contradiction:
Improvedraining speedVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The draining system is segmented into separate, simple components: a coupler that attaches to the drain port, a flexible hose for fluid transport, and a container for collecting fluid. Each component is simple in design, but together they achieve fast and clean draining, managing complexity through modular segmentation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupler is designed with universal applicability, featuring a generic mounting structure that can attach to various drain port configurations. The hose provides multi-functional capability by serving as both the fluid conduit and the positioning element. This universality reduces overall system complexity while maintaining high draining productivity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
