Removable CO Sensor Module for Portable Generator Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable generators operating in enclosed or semi-enclosed spaces face challenges with carbon monoxide (CO) gas buildup, as existing systems fail to effectively detect high CO levels and shut down the engine promptly to prevent further CO production.
Innovation Solution
A removable and replaceable CO sensor module is integrated into the portable generator, equipped with a CO sensor, module battery, and a mounting system that alerts users audibly and visually to high CO levels and automatically shuts down the engine to prevent further CO production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a CO sensor module is integrated into the portable generator, then CO detection capability is improved, but device complexity increases
Solution Approach 1:
The CO detection system is segmented into a separate, removable sensor module that can be independently installed and maintained. This module includes the CO sensor, battery, and alert system as distinct components from the generator engine, allowing the detection function to be added without redesigning the entire generator system.
Solution Approach 2:
The sensor module serves as an intermediary component between the generator exhaust and the user alert system. It detects CO levels in the exhaust stream and translates this information into user-friendly visual and audible alerts, bridging the gap between the harmful exhaust gas and the user without requiring direct integration into the engine control system.
2Ease of repair
If the CO sensor module is made removable and replaceable, then ease of repair is improved, but reliability may worsen due to connection points
Solution Approach 1:
The sensor module is designed as a separate, self-contained unit that can be removed and replaced without affecting the generator's core components. This segmentation allows the sensor to be easily replaced by users while maintaining reliable connections through dedicated mounting interfaces and wiring harnesses that are designed for repeated connection and disconnection.
3Measurement precision
If the sensor portion extends away from the mounting portion, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The sensor portion is extended away from the mounting portion along the longitudinal axis of the module, positioning the CO sensor closer to the exhaust stream while keeping the mounting interface at a convenient location on the control panel. This spatial arrangement in a different dimension allows the sensor to be optimally positioned for detection without complicating the mounting structure.
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
The CO sensor module effectively detects high CO levels (up to 400 ppm) and shuts down the engine before user alert systems are triggered, ensuring safety by preventing CO buildup in enclosed spaces.
Implementation Method 1
a CO sensor positioned within the sensor portion of the housing and configured to detect concentrations of CO

AI summary
A CO sensor module includes a housing, a CO sensor, and a module battery. The housing has a first portion that is configured to be removably inserted into a compartment of a generator and a second portion that is configured to be positioned outside of the compartment. The CO sensor is positioned within the first portion of the housing and is configured to detect concentrations of CO. The module battery is positioned within the housing and is configured to power the CO sensor module. The second portion of the housing includes a mounting ring that is configured to abut a control panel of the generator in an installed position.
