Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting structures for boost pressure sensors in electronic turbocharger engines face challenges such as heat damage, complex assembly processes, increased costs, and reduced precision of intake air pressure signals due to high temperatures and layout constraints, particularly in tropical climates where intake air temperatures exceed the sensor's heat resistance.
Innovation Solution
An adapter structure featuring a heat-resistant or heat-isolating pressure sensor adapter with a channel and a fixing unit that allows for secure mounting of the boost pressure sensor on the intake manifold without layout constraints, using a heat-resistant material and a channel design that minimizes heat transfer and maintains an airtight seal, along with a heat radiation unit to dissipate heat and improve signal precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the boost pressure sensor is directly mounted on the intake manifold, then the sensor can detect intake air pressure, but the sensor is damaged by high temperature intake air
Solution Approach 1:
The mounting structure is divided into separate components: a mounting bracket positioned away from the intake manifold and a hose connecting the manifold to the sensor. This segmentation allows the sensor to be isolated from high temperature zones while maintaining pressure detection capability through the connecting hose.
Solution Approach 2:
A hose is introduced as an intermediary element between the intake manifold and the boost pressure sensor. This mediator transmits the pressure signal from the high temperature environment to the sensor located in a cooler area, protecting the sensor from direct heat exposure while maintaining functional connectivity.
2Object-affected harmful factors
If the boost pressure sensor is mounted far from the intake manifold using a mounting bracket and hose, then the sensor is protected from heat, but the layout is constrained and assembly is complex
Solution Approach 1:
The mounting bracket is designed with multi-functionality, serving both as a structural support for the sensor and as a heat shielding element. This universal design consolidates multiple functions into a single component, reducing overall structural complexity while maintaining heat protection capabilities.
3Device complexity
If the sensor is mounted in high temperature environment, then the structure is simple, but the precision of pressure detection signal deteriorates
Solution Approach 1:
The hose acts as an intermediary that separates the sensor from the high temperature environment while transmitting the pressure signal. This mediator enables the sensor to operate in cooler conditions, maintaining signal precision without requiring a completely simple mounting structure.
