Solution Overview

Problem

Existing oil collection systems in vehicles suffer from spillage, environmental contamination, and inefficiency due to their static nature, lack of heat resistance, and separate disposal requirements, leading to increased cleanup time and risk.

Innovation Solution

An oil shield device made from heat-resistant polycarbonate material with a transparent body, extended face, hollow handle, and spout for controlled oil flow, providing a one-handed solution for collection, containment, and disposal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a static receptacle is used to collect oil, then the collection system is simple in structure, but oil spillage and contamination occur due to uncontrolled oil flow

Engineering Contradiction:
Improvecollection system structureVSAvoidoil spillage and contamination
Core Design Contradiction:
Device complexityVSObject-generated harmful factors

Solution Approach 1:

The patent transforms the static receptacle into a dynamic system by integrating a pump that actively draws oil from the draining orifice. This dynamic oil extraction system controls the flow rate and direction, preventing uncontrolled spillage while maintaining relatively simple device structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces an intermediary containment chamber between the oil source and final storage. This intermediate chamber with controlled discharge mechanisms prevents direct uncontrolled flow, reducing spillage and contamination while adding only moderate structural complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If traditional materials are used for the receptacle, then the device is inexpensive to manufacture, but the receptacle warps or melts when exposed to hot motor oil

Engineering Contradiction:
Improvereceptacle manufacturing costVSAvoidreceptacle structural integrity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent employs composite or specially formulated heat-resistant materials for the receptacle construction. These materials combine thermal stability with manufacturing feasibility, ensuring the receptacle maintains structural integrity when exposed to hot motor oil while remaining practical to produce.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes the material parameters of the receptacle by selecting materials with higher melting points and thermal stability. This parameter change allows the receptacle to withstand hot oil temperatures without warping or melting, while still being manufacturable through standard processes.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If oil collection and disposal are separate operations, then each function can be optimized independently, but additional transfer steps increase time and spill risk

Engineering Contradiction:
Improveoil change efficiencyVSAvoidintegrated system design
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the oil collection, temporary storage, and disposal functions into a single integrated device. The receptacle system with built-in pump and controlled discharge combines these operations, eliminating separate transfer steps and reducing overall system complexity despite the multi-functional requirement.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent designs the receptacle as a multi-functional device that performs collection, containment, and controlled disposal of oil. This universal design consolidates multiple operations into one device, improving productivity by eliminating sequential transfer steps while managing complexity through integrated design.

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

4Ease of manufacture

If no visual monitoring feature is provided, then the device is simpler to manufacture, but the user cannot monitor oil level and may overflow

Engineering Contradiction:
Improvedevice manufacturing complexityVSAvoidoil collection control
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent incorporates visual monitoring features such as transparent or translucent sections in the receptacle, or level indicators that change color or become visible at specific oil levels. This allows users to monitor oil collection without complex manufacturing, preventing overflow while adding minimal structural complexity.

Inventive Principle:
Principle #32Color changes
