Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to effectively adjust airflow characteristics in modified air intake and airflow pipes to match the requirements of sensors, leading to inaccurate monitoring due to differences in pipe diameters, and existing adapters do not provide a practical means to alter flow rates specifically for air flow sensors in automotive applications.
Innovation Solution
A flow adapter with interchangeable sleeve inserts of varying diameters that can be nested to alter airflow rates, allowing for installation and removal without sensor removal, and accommodating different sensor configurations to optimize airflow matching sensor requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pipe diameter is altered to match sensor requirements, then measurement precision is improved, but device complexity increases due to needing multiple sensor types for different pipe sizes
Solution Approach 1:
The adapter sleeve is inserted inside the existing pipe, creating a nested structure where the adapter (inner element) modifies the flow characteristics within the original pipe (outer element). This allows the sensor to remain in its original position while the adapter sleeve recreates the original pipe diameter, solving the measurement accuracy problem without requiring sensor replacement or complex reconfiguration
Solution Approach 2:
The adapter sleeve acts as an intermediary element between the modified large-diameter pipe and the sensor designed for a smaller diameter. It mediates the flow characteristics by restricting the flow path to match the original specifications, allowing the sensor to function correctly without direct modification to either the pipe or sensor
2Measurement precision
If adapter sleeve is inserted to restrict flow area, then air speed increases and sensor accuracy improves, but device complexity increases
Solution Approach 1:
The adapter sleeve applies flow restriction only in the specific local region where the sensor is located, rather than modifying the entire pipe system. The sleeve maintains the original pipe diameter elsewhere, creating a localized modification that affects only the measurement zone. This localized approach simplifies the overall device by avoiding comprehensive system redesign
Solution Approach 2:
The adapter system is segmented into removable, interchangeable sleeves that can be independently selected and installed. Each sleeve is a discrete component with specific dimensional characteristics, allowing the system to be divided into modular units rather than requiring a monolithic complex structure
3Adaptability or versatility
If multiple sleeve sizes are used to match different sensors, then adaptability improves, but device complexity increases
Solution Approach 1:
The adapter sleeve design incorporates universal features including standardized connection interfaces, adjustable positioning mechanisms, and a modular structure that can accommodate multiple sensor types and configurations. A single sleeve design can serve multiple functions by adjusting its position or combining with different end fittings, reducing the need for numerous specialized components

Function Achieved in This Case
The adapter effectively adjusts airflow to match sensor specifications, enhancing airflow speed and accuracy by varying the cross-sectional area within the pipe, thereby optimizing airflow monitoring for sensors, and allowing for flexible adaptation to different sensor sizes and positions.
Implementation Method 1
One or more adapter sleeves 50 are placed within an airflow tube to restrict the diameter of the tube resulting in an increase in the air speed through the area of the pipe where the adapter is placed
Data Source
AI summary
An adapter for a pipe is disclosed where the adapter changes the effective inside diameter of the tube to increase the airspeed flowing through the area where the adapter is placed. The adapter is utilized in automobiles where to adjust engine parameters based upon the requirements from the various sensors. This allows original sensors to be used in pipe while providing the overall appearance of a larger section of pipe. A kit including a number of nesting adapters is provided to allow altering of the cross sectional area of the pipe. The location of the sensor is maintained in the center of the pipe and the adapter(s) engage, nest, or connect to cause a progressive reduction of the pipe diameter until the optimal air flow speed is achieved based upon the requirements of the sensor.
