Solution Overview

Problem

Existing gas pressure reducers for internal combustion engines require complex and time-consuming calibration processes, involving disassembly and reassembly of components, which is inefficient and resource-intensive.

Innovation Solution

A pressure reducer design featuring a central containment body with a solenoid valve, pressure sensor, and a slider mechanism within a cylindrical jacket, allowing for adjustable pressure reduction without disassembly, using a screw connection and grub screw for precise positioning and locking, enabling easy adjustment of the pressure by rotating the jacket.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If precision calibration is done inside the jacket by inserting or removing spacers, then measurement precision is improved, but device complexity and loss of time increase due to required disassembly and reassembly

Engineering Contradiction:
Improvepressure calibration precisionVSAvoidcalibration time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The spacer is pre-positioned outside the jacket at a predetermined location that corresponds to the desired pressure calibration point. This eliminates the need for disassembly and reassembly during calibration, as the spacer's position is established in advance and simply needs to be engaged with the piston during operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The spacer acts as an intermediary element that translates a simple external positioning operation into precise internal calibration. By positioning the spacer externally at a predetermined location, the complex internal calibration process is simplified while maintaining measurement precision.

Inventive Principle:
Principle #24Intermediary (Mediator)
