Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers lack understanding of fuel system maintenance, leading to carbon buildup and performance issues in vehicles due to dirty fuel injectors, which can cause misfires and decreased efficiency.
Innovation Solution
A fuel system demonstrator device with dual spray nozzles and a pump system that visually demonstrates the impact of carbon buildup on spray patterns, using electric or manual pumps to simulate clean and dirty injector conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If consumers use fuel system cleaners to prevent carbon buildup, then engine performance is maintained, but consumers still lack understanding of the internal workings and importance of maintenance
Solution Approach 1:
The patent creates a simplified copy or model of the fuel injection system that replicates the spray patterns and carbon buildup effects. This demonstrator device allows consumers to visually observe the differences between clean and contaminated injectors without needing to open their actual engines, thereby educating them about maintenance importance while maintaining engine reliability through proper care
2Reliability
If fuel injectors accumulate carbon deposits, then spray pattern is distorted causing misfires, but visual observation of this process is difficult for consumers
Solution Approach 1:
The patent extracts the fuel injection spray process from the complex internal engine environment and presents it in an isolated, visible demonstrator device. By taking out the spray pattern generation and carbon buildup process from the opaque engine interior, consumers can directly observe the distortion effects that would otherwise be invisible, understanding how deposits cause misfires and efficiency loss
3Duration of action of stationary object
If preventative maintenance is performed regularly, then carbon buildup is inhibited and performance is preserved, but consumers often ignore maintenance until issues arise
Solution Approach 1:
The patent enables preliminary education about maintenance importance before problems occur. By allowing consumers to preview the negative effects of carbon buildup through the demonstrator device in advance, they can make informed decisions about preventative maintenance, increasing compliance with maintenance schedules and extending engine life before issues actually arise
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Educates consumers on the effects of carbon buildup, promoting preventative maintenance and maintaining engine performance by visually illustrating the difference in spray patterns.
Implementation Method 1
a pump system operatively connected to the plurality of spray nozzles and configured to draw liquid from a liquid reservoir and to provide liquid to the first spray nozzle and the second spray nozzle

AI summary
Disclosed is a fuel system demonstrator device having a housing assembly that defines a demonstrator cavity, a partition dividing the demonstrator cavity into a first nozzle chamber and a second nozzle chamber, a plurality of spray nozzles, and a pump system. The plurality of spray nozzles includes a first spray nozzle positioned in said first nozzle chamber and a second spray nozzle positioned in said second nozzle chamber. The pump system is operatively connected to said plurality of spray nozzles to draw liquid from a liquid reservoir and to provide liquid to said first spray nozzle and said second spray nozzle. The first spray nozzle creates a first spray pattern, and the second spray nozzle creates a second spray pattern that is different from the first spray pattern.
