Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a heating element is used to heat a medium, then heating efficiency is improved, but combustion gas leakage into the interior can cause damage and reduce efficiency
Solution Approach 1:
The detection means is installed in the interior of the heating device housing to proactively detect combustion gas leakage before it causes damage. The spectroscopy unit continuously monitors the interior space, enabling early warning and preventive action against leaks from the heating element.
Solution Approach 2:
The detection means acts as an intermediary between the heating element and the interior environment. It detects combustion gases that escape from the heating element through the exhaust pipe, providing a monitoring layer that alerts to potential failures without directly interfering with the heating process.
2Reliability
If detection means is added to detect combustion gas, then safety is improved, but device complexity increases
Solution Approach 1:
The detection means uses spectroscopy (optical/electromagnetic method) to detect combustion gases instead of mechanical or chemical detection methods. The spectroscopy unit analyzes the absorption characteristics of gases at specific wavelengths, providing a non-contact, highly specific detection approach that reduces mechanical complexity.
Solution Approach 2:
The detection means is designed to detect various combustion gases (CO, CO2, NOx, SO2) using a single spectroscopy unit that can analyze multiple gas types simultaneously by monitoring different wavelength absorptions, reducing the need for multiple separate detection systems.
3Measurement precision
If openings are provided in the detection device housing, then gas detection capability is improved, but dirt and liquid contamination increases
Solution Approach 1:
The opening in the detection device housing is oriented vertically to utilize gravitational separation. Combustion gases rise upward through the opening while heavier particles like dust and liquid droplets settle downward due to gravity, allowing the sensor to detect gases without being contaminated by particulate matter.
